[Elecraft] [KRC2] No KRC2 found error
I've looked through the archives, and have not found a similar situation to mine, so here goes: 1) I can re-download v1.5 firmware to the KRC2 without a hitch. 2) Every time I try to use the config utility, it first tells me 'v1.5' firmware is loaded, then it tells me that 'No KRC2 found', with the usual helpful information on setting baud rate, etc. 3) I've tried this will all the following connection hardware: a) Radio Shack long white USB-serial cable (this one has worked with everything else I need for serial communication so far, including K3 serial, LP-Bridge, etc. etc.) on a Windows XP Home laptop. b) Dynex DX-UBDB9 USB-serial cable (this uses the Prolific chip set, and doesn't work, for instance, with my Icom-7000 memory programming software, hence the reason I bought the Radio Shack cable on a recommendation from the Icom software author) on a Windows XP Home laptop. c) A real hardware serial port on a Windows XP Pro laptop. I've tried setting 4800 bps, 8 bits, no parity, 1 stop, no handshaking in the COM port property panel under the device manager, as well as disabling the UART TX/RX FIFO. Nothing seems to help. I've spent several hours tinkering with this, and have not been able to figure out why the downloader can talk to the KRC2, and the config utility can report the firmware version, but then balks at any further communication (attempted configuration downloads fail, as well). I've also tried pulling all the RS-232-related jumpers except W9 and W10 (RxD and TxD) but it didn't seem to make any difference. Of course, the D/L switch is set in the proper position. Any ideas? I'm at wit's end, and any help would be appreciated. 73, -- Dave, N8SBE __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KRC2 Config Software Problem
Yep. I have the same problem, or at least had it, since I haven't tried it for quite a while. I've tried all sorts of things including a (gasp!) real serial port, and nothing worked. The most peculiar thing is that I have no problem re-flashing the KRC2, but I can't change the configuration with the configurator program. I need to do this so I can drive a 3 of 8 encoded remote antenna switch. I even took hi-res shots of both sides of the completed PCB, and emailed them to Elecraft support (at their request), but aside from being told they were very good shots, I never heard back. I'm finally about to complete my antenna system, and it would be nice to be able to use the KRC2 for what I bought and built it for. 73, -- Dave, N8SBE Original Message Subject: [Elecraft] KRC2 Config Software Problem From: K3RWN rwnewbo...@comcast.net Date: Tue, November 23, 2010 8:02 pm To: Elecraft@mailman.qth.net Has anyone had an issue with trying to get the PC to send program data to the KRC2 Config Utility?

[Elecraft] WTB: XV432 Transverter (receive-only OK)
Folks, I'm in great need of a 432 MHz transverter (actually if the transmitter doesn't work, that's OK). I'm in the SE Mich area, and can meet someone to pick it up. This is work-related, and I need it for a road trip that is currently (last-minute) scheduled for this coming Monday, Jan 25, 2010 into Canada and back. I plan to use it with an RFSpace SDR to listen to 433.92 MHz for signals while on the road. The RFSpace box comes with a spectrum waterfall display and can record and play back any signals I hear across a wide spectrum around the nominal center frequency. It normally only covers up to 30 MHz, but with a suitable downconverter front end, can be made to work on UHF. If you don't want to sell it, if I could borrow/rent it from you, that would be even better. Please respond to the list or direct to my email ASAP. I'll be checking it from work today and tomorrow. 73, -- Dave, N8SBE __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Need to select a dummy load for K3 TX calibr ation...(advice?)
Jim, Don't know what the disposal situation is in your neck of the woods, but where I live in SE Mich, no local hazardous disposal site will handle the material. I asked. I'd have to hire an 'environmental' company to come in and remove the stuff, and then they have certain approved means of breaking down the chemical composition to dispose of it. If you go to the EPA site on PCBs, they have links to the companies that are approved to handle PCB disposal. That's why I'd steer clear of older Cantennas. It's not worth the hassle to get one tested and then to dispose of it, if need be. It would clearly end up costing far more than the bargain price you paid for it in the flea market. Note that this has nothing to do with whether you think the stuff is dangerous or not. Our government has stepped in and decided how PCBs are to be handled. 73, -- Dave, N8SBE Original Message Subject: Re: [Elecraft] Need to select a dummy load for K3 TX calibration...(advice?) From: Jim Wiley jwi...@alaska.net Date: Tue, March 02, 2010 2:48 pm To: Cc: elecraft@mailman.qth.net Disposing of the entire Cantenna would be an over-reaction. The Cantenna can be opened safely, any oil within disposed of, the component parts rinsed in an approved solvent, and reassembled using mineral oil, or NON-PCB transformer oil as the coolant. Use rubber gloves, dispose of the existing coolant in an approved manner. Bottle the waste oil and used solvent it,and take it to a hazardous waste disposal site. Most city dumps will have such a facility.Non-PCB based transformer oils are often available at electrical supply houses or perhaps you can find a friend at the local power company that will give you a fill-up for the asking. The hazard to you and the environment is minimal with such a procedure. PCB based transformer oils, Askarel is the trade name for one such oil, are mildly toxic and must be handled properly, but you won't die or even get sick from a brief exposure. If you get any on your skin, which is unlikely if you use rubber or latex gloves, simply wash with solvent first then copious quantities of soap and water. An approved solvent would be Chevron 325 Thinner, also sometimes known as Stoddart solvent, or equivalent. If transformer oils were all that toxic, hundreds or even thousands of power company employees and communications techs would have tipped over by now- and that hasn't happened. PCBs were once commonly used in high voltage transformers, high voltage caps, and similar items. I am not attempting to say such materials have no hazards, it's just that such hazards are often hyped to levels that are not commensurate with the real risk.

[Elecraft] Screwdriver antennas in salt fog? [was: RE: High Sierra in qst]
It seems that High Sierra is like a number of other screwdriver antenna companies that live in California or Arizona, where they never encounter winter weather with the salt fog spray that is common when driving in northen climates in the winter time. I rebuilt my 1800HS so many times I finally tired of it (the guide on the mast finally fell off, because the tiny screws threads through the thin mast all stripped out), and decided to get a HiQ, based on recommendations from a friend (unfortunately, he lives in Tennessee and so doesn't see the kind of winter weather I get in SE Michigan). After one winter on a trailer hitch mount behind my Durango, the antenna quit working (motor stalled), and I sent it back for repair. Charlie at HiQ called me and asked what did you DO to this antenna? I said, Nothing special, just used it on my vehicle over a Michigan winter. According to Charlie, the inside of the mast was solid salt rock crystal. To his credit, although I think at the time the antenna was just out of warranty, he replaced the entire unit for free. So, I used it through that next summer, but by November, I had traded my Durango in for a Ram pickup, and wanted to change the mount to a stake-mount on the pick up bed just behind the cab, for clearance for a 5th wheel tow, and also to try to keep it out of the salt fog. I actually never got around to mounting it until a few weeks ago, and had left the antenna stored in the garage over the winter. When I tried it out, the motor was stuck again. I've not had time to contact HiQ again, and I understand that Charlie sold/transferred the ham radio portion of the business to someone else, so he can concentrate on DoD contracts, which I'm sure are much more lucrative than the ham trade. I fear that this time I'll end up having to pay to replace the antenna, and these things are definitely not cheap. So, long story short (too late): Is there anyone on the list using somebody's much-vaunted screwdriver design that has actually survived northen winters where they use salt on the roads, without a lot of maintenance headaches? I would think that with the advent of the KX3, a lot more folks on this list will be considering going HF mobile. 73, -- Dave, N8SBE __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] OT: WWV-driven station clock that displays zulu time
As with all things RF, your mileage may vary. I have a wall-type clock I picked up at Dayton a year or so ago, in the bargain pile in the flea market for $10 (brand name unknown, but it has a sticker on the back that says Made in China). Works fine, until you get a marginal signal from WWVB (which is on 60 kHz, by the way -- check out the WWVB web site [http://www.nist.gov/pml/div688/grp40/wwvb.cfm] to see how they pump out a lot of power out on 60 kHz, also the format of the timing signals, which are set at the rate of 1 bit per second). Apparently some of the chip sets don't bother to check the error bits, and will set weird times and dates if a bit gets lost here or there. I keep this particular clock in my office on top of the cube cabinet so it at least has a clear view west over the cube farms out the other side of the building, and sometimes in the morning when I come in, it will be showing a completely wrong date or some odd time. Placing it in the nearby east-facing window across the aisle and forcing a synchronization corrects it. I also have a Citizen 'atomic' watch that works quite well at home at night on the dresser (the WWVB 'atomic' clocks auto-sync at 2 or 3 in the morning local time to take advantage of the enhanced night-time propagation on 60 kHz), as long as I keep it away a foot or so from my CDMA-based Sprint cell phone. Otherwise, emissions from the phone charging circuitry seem to interfere with it. I would certainly welcome something that would increase the accuracy of the clock in the K3. It tends to wander quite a bit, and it's a hassle to have to dump all the various programs I have talking to the K3 over the serial port via Larry's (N8LP) excellent bridge program, so I can run the K3 utility to synchronize the K3 clock to the computer clock.

That means you will need to get a wall mounted clock that is large enough for you to see and it probably should be mounted on a wall that is facing the WWVB signal you are trying to receive for best reception of the WWVB signals which is hit or miss most nights.

Re: [Elecraft] Bluetooth handsfree interface [was: KX3 netbook]
Ben, Someone recently had written an article (in QST?) about re-purposing some of the steering-wheel mounted switches in his vehicle. He was snooping on the vehicle bus for this application. Not for the timid, I would think, and pretty specialized by vehicle manufacturer. Otherwise, mounting a PPT switch somehow on the wheel, assuming the mechanical issues are overcome -- how do you route the wiring, or if it is wireless itself, how do you get power to it, or does it use a small button cell battery? You can see that the devil is in the details. Joe, You probably have a point, but not every state or locality has that particular restriction. In the few cases I've studied, they seem to dwell on hand held devices. If you have a PPT switch clipped to your shirt, you may be OK. But of course, we all know that the arresting officer is not being paid to make judgement calls of that sort. I'd rather not debate the legalities on this list, since that could very quickly explode into something that Eric would have to squash. I just brought it up as a thought starter for the 'wish list', if the Elecraft folks could come up with an imaginative way to implement this at a reasonable cost. I live in SE Michigan, and right now, I can't use my amateur equipment in nearby Ontario when mobile, because they have a no handheld devices, except first responders law in effect.

Re: [Elecraft] Bluetooth hands free interface (AWUI)
Fred, Thanks for your insights on this subject (AWUI). A new twist in bluetooth is BLE (bluetooth low energy). Likely subject to the same limitations as regular bluetooth, but promises to be accommodated in low-power devices that regular bluetooth power levels would quickly drain. The only example of a product currently using BLE that I know of is a heart rate monitor for folks that are exercising. The signal from the chest band is picked up by a bluetooth-equipped smartphone and piped into a app that tracks your workouts. There are complaints from users, though, that the BLE signal doesn't penetrate their bodies -- if they put their smartphone in their back pouch when bicycling, for instance, their body blocks the signal. Might be OK, though, for headphone/headset applications. TI has a BLE mini development kit CC2540, which is sitting on my office desk. I've not had the time to play with it, yet. Comes with programming cables, etc., so you can experiment with the technology. 73, -- Dave, N8SBE Original Message Subject: RE: [Elecraft] Bluetooth hands free interface (AWUI) From: Fred Townsend ftowns...@sbcglobal.net Date: Fri, June 03, 2011 4:04 pm To: 'Dave New, N8SBE' n8...@arrl.net Cc: elecraft@mailman.qth.net Dave I think you raise some very good points. The need for an Amateur Wireless User Interface (AWUI) is a great one. Note I did not say blue tooth for good reason. Bluetooth is full duplex where clearly a half-duplex solution is needed. Before you say you could use VOX think about the portable environment where you can't control the noise around you. Spectrum pollution brought to by the auto horn, the baby crying, and audible aids for the blind. If you want to see how not to do amateur Bluetooth (ABluetooth) look no further than Yaesu. Both stereo and monaural interfaces are offered for the FTM-350. Since it has two separate receivers a stereo interface makes a lot of sense. However their BH-1A (stereo) interface only works in stereo when listening to the commercial FM broadcast band! For the ham bands you need to use the BH-2A monaural interface. Thank you Elecraft for figuring out a stereo headset can be of great value in the ham bands. Furthermore when the cost of the BU-1 (Bluetooth) option and the headset is combined you have a gold plated option that doesn't even do what you want it to do. Oh, one more thing. Look at the Yaesu headset model numbers. The stereo is a dash 1 and the monaural a dash 2. I hope that was mentioned on that marketing guy's performance review. So how do you go about creating a better wireless interface? Sure it's sexy to leverage chipsets off the high volume applications like cell phone Bluetooth. I always like it when I can use a chip someone else has paid to develop. Maybe we should be looking at Zigbee chipset rather than Bluetooth. The wider bandwidth could be used to provide full remote control of the rig. At a minimum then provide the functions available on many of the DTMF microphones... Up/Down frequency, etc. Make the interface two parts so you can put the PTT interface on a belt clip. You could have a plug-in for a leg mounted key too. Don't make it as good as. Make it better. How cool to say you are using an Ah woo ie (AWUI). de Fred, AE6QL -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Dave New, N8SBE Sent: Friday, June 03, 2011 10:24 AM Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] Bluetooth handsfree interface [was: KX3 netbook] Actually, a bluetooth interface, especially for headset use, is a serious consideration.

Re: [Elecraft] [K3] K3EXREF K144REFLK and K144XV
Wayne, Thank you for your detailed answer. I was following the conversation (or thought I was) that the external reference and transverter lock was another way to get high stability/accuracy at UHF and higher frequencies. I guess the issue then becomes, which is more annoying and/or more effective? Maybe I'm missing something obvious, but wouldn't a .25 (or better) ppm-calibrated TXCO be less expensive than all the other stuff, and take up a lot less room (and weight)? I'm really curious about this (and the RTC question I posed) mainly because I'm working with a supplier right now on a fix for a drifting time-of-day clock issue, and the proposed solution involves a Seiko TXCO oscillator that operates over -40C to +85C (automotive interior) and supposedly gives .5 ppm. 73, -- Dave, N8SBE Original Message Subject: Re: [Elecraft] [K3] K3EXREF K144REFLK and K144XV From: Wayne Burdick n...@elecraft.com Date: Thu, June 09, 2011 2:08 pm To: Dave New, N8SBE n8...@arrl.net Cc: elecraft@mailman.qth.net, Tim Taylor tim-tay...@comcast.net, David Pratt da...@g4dmp.fsnet.co.uk Dave, The 49 MHz 1-ppm oscillator is a TXCO, and it works well (0.5 ppm from 0 to 50 C).

Re: [Elecraft] New Sanyo eneloops
The long recharge times (at least with the supplied/supported Sanyo/Panasonic chargers) are off-putting. I use Duracell Renewals that come with a lightweight switching power supply to re-charge my camera flash AA batteries in 1/2 hour (they will actually tolerate a 15 minute charge cycle). That way I can flash away with one set while the other set re-charges. Maybe not the same application, but the long re-charge time for the FT817, for instance, in terms of 6 hours or more, was more than I could take.

Re: [Elecraft] [K3] K3EXREF K144REFLK and K144XV
Geez, I gotta quit relying on my memory. From the Dallas datasheet:
The output is accurate to ±2ppm (±1 min/yr) from 0°C to +40°C and to
±7.5ppm
(±4 min/year) from -40°C to 0°C and from +40°C to +85°C.
Not exactly .5 ppm, but this is for a different application (RTC) than
what we were discussing.
Beats our current ±30ppm on our existing time-of-day design, which
works out to ±80 seconds/month.
I'd certainly be happy if the K3 clock would stay within ±1 min/yr...

Dave,
The 49 MHz 1-ppm oscillator is a TXCO, and it works well (0.5 ppm
from 0 to 50 C). Originally we thought we would not be able to hit
this target without adding firmware-based correction.
I did implement the firmware correction, but I wasn't happy with it,
because it didn't provide much of an improvement beyond 0.5 ppm with
all oscillators tested. What I found is that I had to create data for
every 1 degree C, rather than every 5 degrees, in order to get to hit
a more aggressive 0.25 ppm target. But the manufacturer of the TCXO
had predicted that 5-degree data points would be sufficient for the
algorithm, and that is what they supply with the oscillators. We could
ask the for 1-degree data, but that would increase the cost (not to
mention create five times as much data). It would also not be of much
help to those who already had 1-ppm TCXOs installed.
What we could do in a future release is provide a way for customers to
manually generate and use 1-degree data. Call it Method 4. It seems
a bit onerous, but here's the idea: First, you'd put your K3 in the
refrigerator long enough to get to 0C, or the desired low operating
temp. Next, set the rig up with an accurate frequency counter
connected to the output of the oscillator, and put the cover back on,
or at least part of the way on (the freq counter cable has to come out
at the back or side). Then, as the radio heats up, write down the
oscillator frequencies for each 1-degree point. When it gets as hot as
it's going to get due to ambient temperature, turn on a hot lamp or
hair dryer and aim it at the top cover, about where the oscillator is.
Continue heating and logging data until the desired max operating
temperature is reached.
You could then enter this info into a revised oscillator calibration
data screen in K3 Utility. I'd have to add the firmware necessary to
allow the oscillator to be updated continuously based on 1-degre data.
This is a long answer to your question. It begs the further question,
Would anyone bother?

What I guess I don't understand is why the TXCO functionality was

I'm disappointed in what appears to be a decision to abandon finishing

On a related note, it wouldn't hurt to do something to fix the real

Re: [Elecraft] P3SVGA
The vertical frame rate also affects the horizontal rate. Think of it this way -- if you have the same number of pixels (1920 x 1080) to paint in the same geometry, then doing it 60 times a second instead of 58 times a second means that each horizontal line must be painted faster, and therefore the individual pixel times are shorter (the pixel clock rate is faster). So, yes, changing the vertical refresh also affects the horizontal timing, and could very well cause a monitor that can't adjust the pixel clock to match to show a wrong-width display. 73, -- Dave, N8SBE Original Message Subject: Re: [Elecraft] P3SVGA From: Paul Saffren pa...@elecraft.com Date: Fri, March 30, 2012 2:21 pm To: Dave New, N8SBE n8...@arrl.net Cc: elecraft@mailman.qth.net Hi Dave, 58 Hz is the vertical sync not the horizontal.

As you know, a 2048 FFT is performed on the SVGA, completely separate from the P3's FFT. In fact the SVGA while very similar to the P3's display by design is not going to be a perfect duplicate. The extra settings within the SVGA menu, such as font size and waterfall color bias are set to be implemented on the next release of SVGA firmware. We found a significant problem in P3 version 1.12 and wanted to get v1.13 out quickly. We're also investigating why a few monitors do not sync correctly at 1920x1080. Would you please message me the steps you performed that locked up the P3SVGA? 73, Paul N5GE-2 wrote SVGA setup here is 1440 x 900 Can't set the HP 2311x to 1920 x 1080 because the right side of the image goes off the screen. Comments (mostly aesthetic) 1. On the P3 screen Marker A and B cursors are the same width as the vertical tuning line. On the VGA display they are at least 2 or three times the width of the tuning cursor. The tuning lines and the cursors should be the same width on the SVGA screen as they are on the P3 display. 2. The tick marks horizontal line at the bottom of the screen are shorter than the ones on the horizontal line at the top of the screen by a pixel or two. 3. Setting the font size on the SVGA only changes the font size in the label at the top left of the display. Example MKR A: 3.524.00 4. I like the fill below spectrum line feature. 5. A few times while moving the A and B markers the screen on the SVGA locked up. Turning the P3 off and on resets the problem. Thanks for all you guys do for us.

Re: [Elecraft] K3 won't shut off, turns on by itself
Just a hunch, but if you have a KCR2, make sure it is powered if it is connected to the AUX port. A couple of weeks ago, I had unplugged the power cable form the KCR2, and when the rig was powered on, it hung and did all sorts of odd things, including not powering off in response to the K3 front panel power switch. After I pulled the AUX cable from the KCR2, things started working again. Nowadays, I ensure the KCR2 is either not on the AUX bus, or is powered up when the K3 is powered up.

Try unplugging all AUX and RS-232 cables from the back of the K3. I've had computer programs that were accessing the K3 'hang' and then you couldn't manipulate the menu system from the front panel, until I unplugged the offending cable(s).

Re: [Elecraft] P3 generates noise on 144MHz
The point is that splitting the ground planes in an attempt to isolate them, often makes the situation the PCB designer thought they were fixing much worse. It's a case of knowing where the actual return paths are, and minimizing the length of those return paths. The other half of the EMC equation is proper loading of signal lines, to shape the edges, and suppress ringing. It is far more effective to put series 'ballast' resistors in the signal lines, rather than try to suppress EMC with capacitors across the lines to ground. Please refer to the posted EMC tutorial links I posted below for graphics/explanations. Designing for EMC is not a easy chore, but starting with a bad PCB design will make it almost impossible to suppress systems issues that may crop up after the layout is 'frozen' and the unit is headed for production. At that point, trying to fix the issues with shielding and/or ferrite cores is very expensive, and often doesn't produce the desired results. Nothing short of re-laying out the offending PCB will suffice in the majority of cases. 73, -- Dave, N8SBE Original Message Subject: Re: [Elecraft] P3 generates noise on 144MHz From: hawley, charles j jr c-haw...@illinois.edu Date: Mon, February 18, 2013 1:08 pm To: Dave New, N8SBE n8...@arrl.net Cc: Roger Crofts ro...@monitorsensors.com,elecraft reflector elecraft@mailman.qth.net What does the zig zag gap look like and what is the issue with it?

[Elecraft] Google Calendar UTC time issues -- solution [was: RE: Elecraft SSB Net announcement]
Interesting hint to those that use Google Calendar to keep track of net times, etc. I had put these times on my calendar in what I thought was UTC, but it turns out that 'London' time GMT+00 observes daylight savings time, thus throwing the calendar off by one hour if you live in a local time zone that also shifts for daylight time. There are two solutions: 1) Either choose Iceland as the country, and then you call select GMT+00 (No Daylight Savings) in the pull-down, or 2) Go to your settings page (under the little gear icon pull down, and add a calendar (pick show all calendars), and choose GMT+00 (No Daylight Time) in the pull down. Then it will always show up as a pick when you are choosing time zones for a calendar entry, without having to dig through the Iceland time zone picks. I've struggled the past year or so with re-doing all my net reminders every seasonal daylight change, until I just got fed up with it today and did a Google search and found a forum posting explaining how to deal with it properly.

Re: [Elecraft] P3 Noise signature
If it's not found to be a TV monitor with an approximate 40 kHz horizontal sweep rate, then the next most likely will be a switching power supply that runs at 40 kHz, rich in harmonics. I'd look for LED lighting that comes on in the evening, like under-cabinet kitchen lighting, or low-voltage yard lights. I had a couple of light sensor sockets in my front and back porch lights that were radiating when the lights came on automatically in the evening. Also found an automatic coffee maker making a racket, and a switching power supply in a laser printer. You may be able to isolate it to something in your house by turning off circuit breakers in your electrical panel one at a time (or if you like to split the dictionary faster, do one-half at a time, and then cut that in half again, and again). Once you know the circuit, then you can start unplugging or turning things off or on. Having a handheld radio that picks up the noise will be helpful.

I have the hand mic on the front, and the Heil HC-4 set on the back, so one takes bias, and the other doesn't. Also, one takes hi gain, the other doesn't. I find that when I switch from front to rear and back, my K3 remembers the gain, but not the bias. I have to remember to change the bias, also. Is there a way to tell the K3 via some config menu to remember the bias setting, also, so when I switch from front to rear and back, the bias AND the gain switch also? 73, -- Dave, N8SBE Original Message Subject: Re: [Elecraft] K3 - dual mikes at same time - biased and un-biased?

Re: [Elecraft] [K3] Is there a KRC3 in the works?
Don't hold your breath. I've been waiting literally for years to get the configuration code fixed. Apparently because it works for some folk, then it must be my fault I haven't been able to get it to work on no less then three different computers, some with real serial ports. I need to program it to drive a 3 of 8 encoded Ameritron head. I ordered just the head figuring that I didn't need their control box. I'm about to order the Ameritron control box now, because it will accept 1 of 8 from an external box (which the KRC2 does normally) and encode it into 3 of 8 for the remote head. As a bonus, it will allow me to manually select the antenna, if needed. I have to say that my experience with the KRC2 is the only really negative experience I've had with Elecraft gear. Everything else I've gotten from them has run just fine, and I've gotten superb support. The KRC2 is the only glaring exception, and I suppose I'll just have to chalk it up to an old kit that simply isn't on the company's radar any more for proper after-sales support.

Re: [Elecraft] [K3] [KRC2] Is there a KRC3 in the works?
To be clear, I have no issues with interfacing the KRC2 with external devices. The only issue I've had is using the Windows-based program provided on the Elecraft web site to attempt to configure the behavior of the KRC2. It always fails to connect to the KRC2, no matter what settings I try, on both the KRC2 and the computer, including using two different varieties of USB to serial cables (both of which work with all my other equipment, including the K3 and P3), and a laptop from work that has a real serial port. On the other hand, the re-flash program works just dandy. I can re-flash the KRC2 at will, over and over again, ad infitum, ad nauseum. So, I don't think the problem lies in the computer to KRC2 interface. I've been tempted to reverse-compile the KRC2 code file, which is rather small, so I could just patch the configuration table in the flash image, recompute the checksum and re-flash. Maybe if I wasn't putting in 50+ hours a week at my day job, and about 15 hours commuting a week on top of that, I'd feel like I had more time to spend on such a fascinating adventure. I have 30+ years embedded software development experience, so it really wouldn't be all that hard for me. As it is, I'd rather spend what spare time I have building my station and operating, instead of debugging the KRC2 configuration software. 73, -- Dave, N8SBE P.S. Everyone at Elecraft has been really nice when I talk to them about my KRC2 issues, and offer to help, then it just seems to fall into a black hole. It seems to me that the KRC2 support is really just not on anyone's priority list. I guess that would be fine with me, and I could just go about figuring out how to work around it.

My K3 just died, after being left on overnight. It was working fine last evening, and this afternoon, I came down to the shack to start the NA QSO party CW contest, and no receive, no transmit. I've tried a number of things, including re-loading all the firmware, with the requisite reboots, and restoring the configuration file I had saved just before I took the rig out to W8UM field day. During Field Day, we started getting ERR 12V errors, and the rig started spontaneously shutting down, coming up in low power (less than 10W). We had to finish operating the weekend at the 10 W level. Later, I discovered that the rig was suffering from the dreaded tin-plated connector issue, so I ordered the connector upgrade kit, and installed it a couple of weeks ago. All seemed fine at that point, and we did use the rig to make about 50 contacts (at full power) at the Detroit Maker Faire N8M station last weekend. So, here's what I know, so far: 1) When I change the filter/DSP controls, I can hear the receiver noise change accordingly, so it seems that the receive chain is intact at least from the crystal filters to the audio out. 2) I have the subreceiver installed, and I hear (don't hear?) the identical things on it, so it seems likely that it is something that is upstream to both the main and subreceiver, or something they both share (like a mixer/oscillator). 3) I've tried all bands, and none of them are working, BUT 4) I can see signals on the P3 on all bands, so the signals are getting at least to the IF takeout for the P3. I can see signals on ANT 1, ANT2 (I have the ATU), Rx ANT and on the XVTR IN with the KXV3 set to test mode. 5) In all of these cases transmit shows 0 W out. The transmit audio works on USB/LSB, showing ALC and compression readings on the meter. With VOX on, the CW paddle switches the K3 into transmit mode, the TX LED lights, and the CW decode shows the transmitted characters. 6) I tried to do an RF calibration with the K3 utility, and it seems to complete, but the K3 displays E 0400E2 ERR DSE, and I have to power down/up the radio to get rid of the error message. This might just be a red herring, as I've read messages that indicate this could be an overrun error or some other communications error when using the KUSB adapter (which I'm using on a Windows 7 PC). In summary, the K3 serial 3105 seems to behave completely normally, including all controls and displays, except that I cannot hear signals from the antenna, although they are displayed clearly on the P3, and transmit power is nil.

Problems with VPN at remote site delayed that setup. As contest time approached, I decided to deploy my Buddipole out the apartment window and was gonna play around with 100w and dipole config.on 15m. However, I could not hear any signals, at all. Nothing but white noise on all bands. The Buddipole ends in a BNC which I had connected to adaptor for PL259. Tried Ant 1 and Ant 2 with no luck. Thinking adaptor may be bad, I hook BNC to RX in but no sigs there. This morning, more troubleshooting, I discovered that there is no power out (although I was tricked as ATU was finding perfect SWR , HI).

Re: [Elecraft] K3 no xmit, no receive?
Did you ever solve this? My K3 just died, after being left on overnight. It was working fine last evening, and this afternoon, I came down to the shack to start the NA QSO party CW contest, and no receive, no transmit. I've tried a number of things, including re-loading all the firmware, with the requisite reboots, and restoring the configuration file I had saved just before I took the rig out to W8UM field day. During Field Day, we started getting ERR 12V errors, and the rig started spontaneously shutting down, coming up in low power (less than 10W). We had to finish operating the weekend at the 10 W level. Later, I discovered that the rig was suffering from the dreaded tin-plated connector issue, so I ordered the connector upgrade kit, and installed it a couple of weeks ago. All seemed fine at that point, and we did use the rig to make about 50 contacts (at full power) at the Detroit Maker Faire N8M station last weekend. So, here's what I know, so far: 1) When I change the filter/DSP controls, I can hear the receiver noise change accordingly, so it seems that the receive chain is intact at least from the crystal filters to the audio out. 2) I have the subreceiver installed, and I hear (don't hear?) the identical things on it, so it seems likely that it is something that is upstream to both the main and subreceiver, or something they both share (like a mixer/oscillator). 3) I've tried all bands, and none of them are working, BUT 4) I can see signals on the P3 on all bands, so the signals are getting at least to the IF takeout for the P3. I can see signals on ANT 1, ANT2 (I have the ATU), Rx ANT and on the XVTR IN with the KXV3 set to test mode. 5) In all of these cases transmit shows 0 W out. The transmit audio works on USB/LSB, showing ALC and compression readings on the meter. With VOX on, the CW paddle switches the K3 into transmit mode, the TX LED lights, and the CW decode shows the transmitted characters. 6) I tried to do an RF calibration with the K3 utility, and it seems to complete, but the K3 displays E 0400E2 ERR DSE, and I have to power down/up the radio to get rid of the error message. This might just be a red herring, as I've read messages that indicate this could be an overrun error or some other communications error when using the KUSB adapter (which I'm using on a Windows 7 PC). In summary, the K3 serial 3105 seems to behave completely normally, including all controls and displays, except that I cannot hear signals from the antenna, although they are displayed clearly on the P3, and transmit power is nil. Any suggestions would be most welcome. 73, -- Dave, N8SBE Original Message Subject: [Elecraft] K3 no xmit, no receive?

Re: [Elecraft] KX2/KX3 operating tip: Creating a CW "sound stage" using AFX PITCH mode
Wayne, It would really be nice to be able to reverse the sense. That way, as one tunes 'up the band', new signals appearing 'on the right' (higher in frequency, but not necessarily in audio pitch, depending on sideband setting) would appear in the right ear, and would slide to the left based on the tuning speed. In other words, instead of statically mapping low-to-high audio to left-to-right ears, allow the user to reverse the mapping, so that it matches the tuning 'sense'. 73, -- Dave, N8SBE __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] Vanity call question
(sorry for the previous blank email -- I keep forgetting that this mailing list strips out HTML-format text) I was originally licensed in 1970 as a Novice in Murfreesboro, TN as WN4SBE, which changed to WB4SBE when I upgraded to Advanced the following year. I kept WB4SBE for 30+ years, even after moving to Ann Arbor, MI in 1982. I finally got off my keyster and passed my 20 WPM Extra in the early 2000's, just before the FCC lowered the code requirement to 5 WPM for all license classes, and eventually doing away with it altogether. Armed with my newly-minted Extra, I figured it was high time to look into a vanity call. For one thing, I had been plagued in certain contests with folks guessing my section as "Virginia?" because of the 4 in the call sign. Don't know why "Michigan" sounds so much like "Virginia", but I figured that changing to an 8 would fix that. I toyed with going with something like my initials (DN or DEN), but I shied away from DN since that is too easily mistaken for "/", and I think DEN was taken in all the short suffixes (W8, K8, N8) at the time. So, I found that N8SBE was available, and I figured the 'locals' would know who I was, based on just changing the prefix. Anyway, "Side Band Engineer" has a nice ring to it (as does "Subacute Bacterial Endocarditis", a throat infection, as related to me by a doctor on 20m phone one day), although I've found that on phone contests, "Sierra" is frequently mistaken for "Kilo", and has resulted in busted QSO's (and even more annoying, N8KBE is now found in the super partial check database, even though that station has not been active in the contests). I've tried using "Sugar Bravo Echo" and had Spanish-speaking stations correct me back to "Sierra Bravo Echo", so I guess you just can't win. On CW, N8SBE has a really nice swing to it, with mostly alternating dahs and dits in groups, helping to separate the characters. What's really funny though, is that the "BE" on the end is the same as the old 'knock/knock" that a a lot of old timers ended QSO's with, and I've actually had folks respond to my callsign with "dit dit". I don't know if they are just letting me know that the frequency is busy, or if they are just playing along with the joke. All I know is that I've had a lot of fun on ham radio over the years (coming up on 50 in 2020), and moving up to Elecraft (first a K3/P3 in 2009, and now K3s/P3 and KX2) has really enhanced my enjoyment of the hobby. Seems I'm discovering something new every day. I made FT8 contacts for the first time recently, using DXpedition mode with the KH1 folks, and it was really nice knowing that they had just as nice of radios on their end as mine.

Re: [Elecraft] P3 Phantom Signals
You do know that you can notch spurious signals out of your receiver? There are instructions for doing so in the operating manual. It's kind of interesting to see how it appears on the P3, though. The spurious will tune across in reverse directions from normal signals, and usually at double speed. If you've notched it out of your receiver (the procedure jiggles the synthesizer frequencies a bit in the immediate area of your receiver passband) you will see it approach your receiver passband on the display and then magically disappear as it crosses your passband cursor. It will then re-appear on the other side. Pretty interesting effect, but perfectly logical, once you understand what is being done 'under the covers' to prevent you hearing that birdie in your receiver. 73, -- Dave, N8SBE Original Message Subject: Re: [Elecraft] P3 Phantom Signals From: Keith Onishi Date: Thu, November 29, 2018 11:43 pm To: Elecraft I have the same on my P3.

Re: [Elecraft] New tuning knob for the KX2
I"ve always wished for a 'ballistic' interface, i.e. the faster you turn the VFO knob the larger the frequency change per turn. On the other hand, I've suffered poor implementations of that feature (uBitX, anyone?), so it would need to be done carefully, if at all. ICOM seems to have managed to come up with what I feel is a good implementation. I used it for years on my old IC-735 (that I sold to partially fund my upgrade to a K3), and now on my IC-7000 that I still use mobile. One of the things I immediately missed on the K3 was lack of a ballistic VFO interface, and lack of band-stacking registers. I guess that Elecraft has had some edict(?) that they don't like ballistic VFO interfaces, so I guess we will all have to live with a fixed tuning rate. Maybe there is a patent thicket that prevents implementing some of the more popular features on competitive radios? Have said all that, I really like using the RIT knob to move large chunks of frequency quickly. For me it's a lot easier than pushing the rate button to shift the tuning rate on the VFO back and forth. And I became recently aware that there is a solution for the band-stacking registers on the K3/K3s, using a special mode for the keypad memory register recall. I haven't tried it yet, but it is now on my to-do list. On my original K3, I did get the upgraded CNC milled knobs (both A and B) from a 3rd party, and really liked them. I've since gone to a K3s, and let the upgraded knobs go to a friend when he bought my old K3. So far, I've not felt like I need to upgrade the knobs on the K3s. They seem more substantial, somehow.

"You always remember your first." :-) My first DX contact as a 16-yr old Novice in August of 1970, was on 15 meter CW (rockbound of course, I still have the 3rd-overtone 7 MHz crystal) with LU2DAW, an Argentinian who turned out to be a retired railroad radio operator, who had done CW professionally for most of his life. He must have been VERY patient with my brand-new shaky 5 WPM CW fist. I used a borrowed Knight Kit T-60 transmitter, a Hallicrafters SX-99U receiver with outboard Heathkit Q-Multiplier, a Dow-key antenna relay, and a 'horizontal' inverted vee antenna in my parent's L-shaped attic. My Morse key was a Radio Shack black plastic special, screwed to a piece of fiberboard. I treasure the QSL card to this day. 73, -- Dave, N8SBE (approaching 50 yrs licensed in 2020) __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Wayne, Some means to GPS-lock the frequency, ala the QRPlabs QLG1: https://www.qrp-labs.com/qlg1.html This would make running a number of really-low-power long-transmit-time digital modes like WSPR and QRSS more practical.

Re: [Elecraft] K4?
I agree. The radios I've seen with touch screens are a real compromise in usability. Either the screen is too small to be useful, or it is so big that many hard controls are sacrificed to avoid making the front panel too large. The worst are the PC-based interfaces, where all hard controls are eliminated. The IC-7300 is a case in point. When I first encountered one, I gave up trying to figure out how to change bands, and had to ask the owner. Of course, you just touch the MHz digit on the display! Obvious, I suppose, in retrospect. The problem with touch displays is similar to 'hidden' mouse movements on PCs. Unless you've read the manual or had someone show you, it is entirely not obvious how to do cool things with the mouse. How many folks know that on Windows 7/10 if you drag a window to the right or left side of the screen, that it will magically re-size to fill just the right-half or the left-half of the screen? Makes it super simple to place two instances of the file explorer side-by-side to assist in doing drag 'n drop operations between windows. How many know that if you drag the winnow top edge (as in a resize operation) to the top of the screen it will automatically fill the screen top to bottom? And if you subsequently drag it off the top, the window will snap back to its original size and position? How many know that if you grab a window title bar, and shake the mouse, that all other windows will minimize? And if you shake the window again, they all come back? I'd bet that at least some of you just learned something about your PC that you didn't know before. There is a least another dozen cool things (like using Ctl-Windows-right or -left arrow on Windows 10 to access multiple desktops of windows). So, how do you implement cool touch- or mouse-movements without leaving novice users in the dust? That's the $64,000 question. 73, -- Dave, N8SBE Original Message Subject: Re: [Elecraft] K4? From: Wayne Burdick Date: Mon, March 25, 2019 12:56 pm To: Bert Cc: Elecraft Reflector The trick is to provide a full complement of "hard" controls for functions accessed most frequently, "in the heat of battle," as they say, while leveraging the touch screen for its versatility. Touchable fields can be added as a backup/shortcut to hard controls. A touch screen inherently offers immediate context-sensitive feedback and in many cases reduced time/effort. Examples include signal selection, zooming, etc. Zooming should also be done right, by resampling at narrower resolution -- is shouldn't just be a "blow-up" of the original pixels, as implemented on some existing radios. Ultimately, get what you pay for. That said, current prices for "high-end" super-radios are ridiculous; they're two to four times higher than necessary. Not only that, they're not configurable or upgradeable. Very un-Elecraft like.

Re: [Elecraft] Searching for Noise (i.e., Samples Thereof)
I've always wanted to better understand the tweaks/handles that we have in the noise blanker/noise reduction algorithms in the K3/K3S. I can 'frob the knobs', until I see some reduction in noise, but I felt it would be much better to not be flying blind, and be able to know just what the various modes do and their parameters do, and be able to actually see some better noise signature to get an idea of whether or not a particular tweak is doing what I thought it was doing. I have the Fred Cady book, and it goes into some detail, but I'd like to see a much better description from the source as to just what all those parameters actually do, and a means to see it actually happen, on the P3, or a scope, hooked to the IF out or similar. I'm plagued with all sorts of noise at my QTH, and I haven't spent much time trying to hunt it all down. I feel I need better insight than to just go around pulling circuit breakers. Some of the stuff is quite likely to be off-premise, as well, which brings me back to likely having to deal with it as best I can at the receiver end of it.

Re: [Elecraft] Searching for Noise (i.e., Samples Thereof)
Thanks for all the tips, guys, especially the MFJ meter references. I have their ultrasonic sniffer, which helped me point out to the local power company some dangling insulators. I have tracked down some on-premise noise sources in the past (in no particular order): 1) The clock on a Mr. Coffee coffee maker. It put out a buzz-saw that could be picked up directly for some distance, plus it coupled to the power line, for an extra boost of signal goodness. 2) A porch light day/night sensor that screwed into the bulb socket. This was amazingly noisy, and only came on at night (natch). 3) A laser printer switcher power supply. 'Nuff said. 4) A doorbell transformer, likely as old as the house (built in 1954). It was mounted on the side of a junction box in the basement, and was exceedingly difficult to track down, as none of the breakers, except the main, would turn it off. Found out later that the previous owner had paralleled two breakers in the panel, likely because he kept tripping one of the circuits in the kitchen or bath -- the effect was that turning off one or the other breaker had no effect on either of those circuits. Thus they were 'mystery' breakers until I pulled the panel cover and discovered what had transpired. I've since had an electrician put an extra panel put in, and some circuits split, because the original panel was completely full with duplex breakers. Making plans now to put in a whole-house generator. Got the go-ahead from the XYL. She is tired of all the power outages we've had in our neighborhood over the last 2-3 years. 73, -- Dave, N8SBE __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] K4 and Linux Infrastructure
Paul, I believe you mistook the 'direction' of DDOS attack I was talking about. The K4 would not be the target of a DDOS attack, but rather an unwitting participant in launching a DDOS attack as part of robot army of IoT devices. Thousands of hacked IoT devices are for rent on the dark web, for any script kiddie that wants to attack a particular target. Also, it may be popular to use hacked web sites, or various documents with trojan horse loads to deliver ransom ware or bitcoin miners, but there are other known vectors, including various open ports found while scanning. It may be the a router would be able to block access, but the very peer-to-peer nature of the K4 (controlling other K4's or being controlled by another K4 or PC, tablet, etc, means that routers would need to allow certain inbound connections through the router or firewall. These allow for interesting attack vectors, which will certainly be exercised, if possible. 73, -- Dave, N8SBE Original Message Subject: Re: [Elecraft] K4 and Linux Infrastructure From: Paul Gacek Date: Mon, June 03, 2019 4:00 pm To: "Dave New, N8SBE" Cc: Elecraft Reflector , Rick WA6NHC Dave DDOS is quite hard for any end point (PC, iPhone, K4 etc) to deal with effectively. If a million zombie Macs decide to simultaneously attack your end point your best chance is as Rick states, a device that makes up the perimeter defenses such as a firewall or cyber security alternative (i.e router, IDP). Most homes don’t have anything particularly sophisticated deployed and are therefore somewhat vulnerable. In truth DDOS attacks are quite rare and typically not aimed at Citizen Dave or his neighbors. Protection albeit optimistic is really in the realm of a corporate network but even then we have a few cases where iconic sites get hammered and go dark. Enabling the K4 to defend against DDOS is a little like building a house to withstand random bits of ISS dropping in unexpectedly; not something I’m expecting to be paying for. Unwanted ransomware or bitcoin mining programs are most likely the result of an unwitting end user at and end point (PC, Android etc) doing something that resulted in the malware ending up on their end point. Could be surfing to a suspect web site (www.PawnStorm4U.com) or even going to a compromised but reputable site such as NASA.gov. Alternatively, it could be someone opening a compromised PDF or Word/Excel attachment. The best protection here is to be cautious and mindful of what you do in the cyber world and absolutely make sure you are running the most uptodate OS (not XP) and to its most current patch level. Presumably but maybe not, the K4 won’t make available to the ham operator a browser that allows them to surf wherever nor an email client that they can read Excel attachments at the whim of the ham operator. That is best done outside of the K4. Hardening Linux, following best practices on coding and penetration testing are all things to be aware of and implement as appropriately.

Re: [Elecraft] Elecraft / IC-7610 comparison
Graziano, Wayne explained to me at Hamvention that the K4 is running Linux. That gets my stamp of approval. 73, -- Dave, N8SBE Original Message Subject: Re: [Elecraft] Elecraft / IC-7610 comparison From: "Graziano Roccon (IW2NOY)" Date: Tue, May 21, 2019 5:45 am To: Alan Cc: elecraft@mailman.qth.net Hello, this is not good for K4. These products are thought to be manage by operative systems and drivers (like Windows or Mac or Linux), this is not the case of the K4 that have a custom "OS" and can't manage that kind of devices. Maybe you can use more complicated and expensive devices thought to be used with RJ-45 ports, where this device use a DHCP and give an ip address to the RJ-45 port creating a private network between the RJ-45 and the device, afterwards the device can access the WIFI network with his wifi adapter and work like a bridge between the two network. In this way, maybe, you can connect the K4 to the wifi in a more "natural" way. Like this one for example: https://www.amazon.com/Vonets-VAR11N-300-Multi-Functional-Wireless-Portable/dp/B01199OGK0/ref=sr_1_fkmrnull_1_sspa?keywords=vonets+VAR11+N-300=1558431899=gateway=8-1-fkmrnull-spons=1 Best regards, Graziano Roccon IW2NOY / W2NOY __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] (no subject)
OEMs have gone back and forth over the years with the "one true ground" vs completely distributed grounding via the chassis. They seem to currently be in the phase of using distributed localized grounding points (with several ground return wires per location), a kind of hybrid grounding system, if you prefer. I've always run a pair of wires back to the battery, but with one important difference. I tie the ground side of the pair near the battery end to the chassis terminal that the battery uses to 'ground' the negative to the vehicle chassis. This way, if the battery negative opens (either because of a loose terminal clamp or a defective battery-to-chassis connection), you won't get a load dump of the entire vehicle's current through your radio's ground wire, radio chassis, and antenna coax shield to wherever you've mounted your antenna. No OEM will ever recommend connecting the negative return of any accessory to the battery negative terminal, because of this. Folks that do this risk a 'thermal event' involving their gear if a load dump occurs. Finally, if your DC power cable came with a fuse in the negative lead, bypass it/take it out! Otherwise, you can blow the fuse in the negative, and put all your transmitter power load (30A peak for a typical 100W HF rig) down your antenna coax shield to (again) where ever you mounted your antenna. Also, put an inline fuse near the battery end in the plus DC lead, to guard against any shorts to chassis in the run to the rig. Most aftermarket installations don't do much to protect the added wiring, and it could chafe and get cut into someplace. Better to blow the fuse at the battery end, than to have another 'thermal event' burning up the wire. Hope this helps. 73, -- Dave, N8SBE > Proper bonding in a vehicle is different from bonding in a fixed > station.

Re: [Elecraft] Mobile high power
Most modern vehicles are tested for EMC in large chambers, where they are bombarded by high-power frequencies that extend up into the microwave range. So, they are relatively immune to external RF fields. On the other hand, they are frequently not designed to withstand a powerful onboard transmitter, unless specifically designed for a particular market, say police/fire/ambulance. In the case of those vehicles, the assembly plant typically installs bonding/ground straps to bond all major metal panels. Unfortunately, regular customers can't get those kits installed at the plant for them, and they aren't very effective as an aftermarket kit, because the customer would have to scrape the paint down to bare metal and access locations that might be completely closed off after assembly to install said straps. The other unfortunate effect of designing for police/fire/ambulance service, is that all those radios are now VHF/UHF and up. No more HF radios. They went out with the state-wide sheriff's networks of old that ran on 40 MHz or so. So, that leaves the amateur radio HF operator twisting in the wind, both for onboard interference from vehicle electronics, and susceptibility of same. I heard that one OEM had declared that no one used HF any more, because they scanned the FCC database looking for amateur station assigned frequencies (ala commercial stations which are assigned fixed channels or groups of channels) and finding none, reached the conclusion that no one is using those bands any more. Thus, all frequencies below 30 MHz are not protected, except for the AM broadcast band in the US, and MW in the EU. OEMs are concerned that their onboard entertainment radios (AM/FM/Sirius/XM) and their tire pressure monitor and remote keyless entry systems have no interference, but everything else can go to pot. At one time, I'm aware that at least one OEM tested using an Icom IC-706 with those dummy-load like 1-inch coil resonated antennas, but I don't know if that is any longer the case. The ARRL TIS (Technical Information Service) maintains a database of information on mobile installations, including official documentation (if any) from various vehicle OEMs on suggested mobile installation guidelines. Some OEMs used to come to Dayton with sample mobile installations, and answer questions but I've not seen them do this for some number of years. Hope this helps. 73, -- Dave, N8SBE __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
