[Elecraft] KAT3 (not KAT3A) issue - older K3 take note
TL;DR: Got a KAT3 in your K3? Next time you have your K3 open, pull out KAT3 and preemptively remove L10 and C10, and replace with a jumper. You don't need them and they are probably messing you up at times. (Are there any other older K3 issues like this? Tell me!) I have an early model K3 that still has all of its original modules. I was having an issue where the power output was sometimes dropping to just a few watts. Running the TX calibration would sometimes fail completely with weird error messages, but if I could get it to run it would get through most of the way but always fail on 52MHz due to high SWR (over 2). With a dummy load or a matched antenna, SWR was over 2 also in normal operation. Of course, this low power situation would magically correct itself after some poking around, though the 52MHz high SWR was consistent. I finally decided that I wanted to do some 6m operating and I used the KAT3 to get matched to the load. I would just operate until something finally decided to fail fully. It did. After a few hours C10 on the KAT3 blew, LOUDLY and smokily. Undoubtedly due to some crazy high voltages presented by the tuner. After some sleuthing in the Elecraft reflector I found the C10/L10 filter issue being well discussed. Pulling them out and jumpering solved all my issues. With the K3, anyway. :) This filter was not included in the KAT3A. If you have one of those, you're good. If you want to know more about the history of this filter it's easy enough to find in the email archives. :) Hope this helps - jeff wk6i -- Jeff Stai ~ WK6I ~ wk6i.j...@gmail.com RTTY op at W7RN Twisted Oak Winery ~ http://www.twistedoak.com/ __ 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] XV222 Mods Question
hi Mike - I checked my notes from field testing the XV222 and didn't see any C12 mod, and I checked my actual XV222 and didn't find any extra caps there. Regarding Z4... there were a series of Builder's Alerts that came out with mods to be made. It's possible that yours is also a field test and/or some of the mods were not done in your version. Don W3FPR may be better able to talk to that, and to have the Builder's Alerts handy in digital form so I don't have to scan them for you. :) Anyway, Alert #5 says Z4 is supposed to be a 56 ohm resistor. I'll have to dig deeper to see what is up with Q1. 73 jeff wk6i On Thu, Jun 10, 2021 at 3:08 PM Don Wilhelm wrote: > Mike, > > Has the paint been cleared from all parts of the enclosure that contact > the 2D connectors? > If not, that could be reason for your observations. > > You might want to remove those capacitors to see if all is well without > them. > I have lots of experience with the Elecraft transverters and do not > recall that as a mod. > > 73, > Don W3FPR > > On 6/10/2021 5:37 PM, Mike Cizek W0VTT wrote: > > Greetings, > > > > > > > > I recently purchased a used XV222 that had some modifications done in the > > local oscillator circuit.

Re: [Elecraft] OT: High school drafting class, ~1975
Not offered in my HS as I recall in 1976 but in college one quarter of it was required. I enjoyed it so much I took the second quarter.

Re: [Elecraft] Where is Elecraft Support ?
Continuing the OT parade, I have one. When I first joined the ASIC team at Western Digital I was assigned to complete a SCSI interface chip and get it into manufacturing. It was a design that they had decided not to produce... except for the fact that one frisky salesman sold it to an passenger jet manufacturer. Said mfr needed, for the whole lifetime of the jet in question, something like 30 units. But since there was a contract signed, we made it. 73 jeff wk6i On Wed, Mar 11, 2020 at 1:19 PM Alan wrote: > My experience with lifetime buys was at HP/Agilent.

Re: [Elecraft] Mobile high power
You see lots of mobile radios out in rural areas. Volunteer fire departments. This need won't go away soon. Vehicle electronic sensitivity is nothing new. At least 20 years ago I recall keying 100 watts in traffic on my morning commute and seeing the trunk of the Lexus in front of me pop right open. Another time I pulled into a parking structure while wrapping up a UHF QSO (short antenna) and set off every car alarm on the floor. Good times. Hopefully improvements have been made since then. 73 jeff wk6i On Mon, May 6, 2019 at 10:12 AM Ken Winterling wrote: > I believe all of the vehicles I've owned have had a statement in their > manuals about transmitters.

Re: [Elecraft] Ideas for an FT8 Radio
Well, since we are dreaming about things that probably won't happen...;) An all in one appeals because it is portable, perhaps even trail ready. There are plenty of good mini keyboard/trackpads units already out there, so use one of those. Since you are using an external keyboard, skip the complexity of a swivel screen. A kickstand would be nice though. You said all mode but it's an FT8 radio so keep it that way; you could maybe include CW if it is easy. It will also need a stable clock... There are more powerful options for CPU nowadays than Raspberry Pi. If you think ahead, this unit could have enough oomph for future digi modes. If it was a solder kit I'd probably be in for one. 5-10W with an option for more watts sounds okay for that.

Re: [Elecraft] CODEC
I bet Mike would appreciate getting back to his issue, which has nothing to do with VOX... Are you using a high end sound card/CODEC?

Re: [Elecraft] OT: Call letter license plate trivia
Years ago I was working with a catering dept at a hotel to set up a conference. I met the new manager named Kate, and it was decided to continue the meeting over lunch. We walked to where her car was parked and I noticed her Ohio license plate: K8WYT. I asked, "Oh, are you an amateur radio operator?" She said, "No. That's me. Kate White." 73 jeff wk6i On Mon, Jul 16, 2018 at 10:41 AM, Jim - N4ST wrote: > Years ago, during the 70's gas rationing in Maryland, I found I could get > gas on either odd or even days with my AA3O license plate. > > 73, > Jim - N4ST > > -Original Message- > From: elecraft-boun...@mailman.qth.net > On Behalf Of Rose > Sent: Monday, July 16, 2018 12:56 > To: Elecraft Reflector > Subject: [Elecraft] OT: Call letter license plate trivia > > Montana has a $25 vanity plate fee, regardless of what the plate "says", > -but- ham radio plates are exempt. > > BUT … I had a very difficult time convincing the local county folks that > my "K0PP" plates were -not- the usual vanity plate they were used to > issuing.

Re: [Elecraft] Who would spend 30 hours+ building an Elecraft K2? (plus: special pricing)
I've built two K2s. The second one was serial number 1250, which at the time was my street address.

Re: [Elecraft] Failing K3 at 3C0L
In a temp multi-op environment it's all to easy to make a mistake.

Re: [Elecraft] Performance of internal USB sound system compared to external one?
The built-in sound card in the K3S works just fine for RTTY decode - MMTTY and 2Tone - but RTTY doesn't require high performance from a sound card. For more demanding modes I can't comment, but I would definitely expect the K3s to meet or exceed the specs of the Rigblaster, which is nothing special. Ken, I would look into your setup in detail. If you can contrive to do a real time side by side test where you can observe both decodes at the same time that would give you confidence that there is really something wrong, or not. 73 jeff wk6i On Tue, Jun 14, 2016 at 11:50 AM, Robert Wood <wood...@gmail.com> wrote: > also curious if anyone has used the USB audio into MMTTY or 2Tone for > decoding RTTY and your report ? > 73 Robert W5AJ > > > -Original Message- > From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Ken > Arck > Sent: Sunday, June 12, 2016 8:27 PM > To: elecraft@mailman.qth.net > Subject: [Elecraft] Performance of internal USB sound system compared to > external one? > > Admittedly, I am a new owner of the K3s and am still learning my way around > it.

Re: [Elecraft] P3 Panadaptor
I'll echo what everyone has said about using the waterfall. Pretty much just maximize the area of the waterfall display to the extent the P3 will let you. Then S is a matter of hopping from trace to trace, and you don't miss the ones you would be missing by tuning past them without the display. Finding a space is easier too. I like a Span of 10 for RTTY. At that size you can see plenty of signals and with practice you can even use the P3 as a tuning aid to tune in the signal when it reappears. 73 jeff wk6i On Sat, Apr 2, 2016 at 1:29 PM, <j...@kk9a.com> wrote: > I added the P3 panadaptor to my K3S line this year I have used it twice - > in the CW WPX RTTY contest and in last weekend's WPX Phone contest.

[Elecraft] K3S on RTTY
I haven't seen much here on the subject so I thought I would share my experience from this past weekend in the RTTY Roundup. We recently upgraded our multi-radio setup with two new K3S-es. Both were operated in FSK-D mode, one at the 2125/2295 tones, and the other at 1445/1615. (That helps me sort them out in the headphones quicker.) Both rigs get the FSK via the ACC port. One rig gets FSK via a Microham box, the other by FSK cables with level shifters built by me. I use Writelog as my contest logger in the mode that allows the K3 and K3S sub Rx to appear as a second radio. The K3S-es were connected via the USB interface. I used the K3S internal sound card on both rigs. And the P3s were connected accordingly with the special cable. I have to say that - other than that one weirdness with the VFO B cursor I posted about the other day - everything ran flawlessly. The internal sound card decoded at least as well as my external cards do. One thing I especially had my eye on was interference between the stations. We run full power and we have experienced wideband interference between 20/40 and 40/80 RTTY that no amount of filtering seemed to conquer. I'm happy to report that the interference is substantially reduced with the new KSYN3A on board. I used to have to pick my transmitting spots very carefully to avoid "bad zones" but now it is almost a non issue. (Woo hoo!) Also, and this of course is subjective, but QRM from neighboring stations also seemed to be substantially reduced. At least, I didn't have to QSY as much as I usually do to get away from someone's gudge. I'll have a better sense for this after a few more events. 73 jeff wk6i -- Jeff Stai ~ wk6i.j...@gmail.com Twisted Oak Winery ~ http://www.twistedoak.com/ Facebook ~ http://www.facebook.com/twistedoak __ 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] suggested PC???
Only you can decide how much PC you need to do what you want to do. If you are just control and logging you can get by with 2-4G of RAM and a fairly modest 160 gig disk drive, and a dual core. Even though the K3s has the USB port I would still get something that would allow you to add one or more real serial port via some flavor of PCI. You never know... A more economical approach is to get a refurbished PC. I currently use a refurbished HP with an added 8 port serial card for my RTTY work (I like hardware modems...). I think it cost me $200 for the PC at the time. And I recently purchased another one for my company that came with Win7 64-bit Pro, for just $75.

Mine isn't. It sends it once and stops. I also tried CW, same result. I
even tried typing the examples in the manual exactly as shown. No luck.
Macbook Pro, OSX Yosemite, USB cable, I downloaded the XG3 app today.
What am I missing? 73 jeff wk6i
ps: I'm using the Mac because my PC wouldn't recognize the USB (which I
think is a problem with the PC, it's USB ports are not behaving in

The decode on the K3 front panel is cool for computer-less work, but as soon as you have a computer it becomes less useful. This is from a serious contesting perspective. When I'm running I'm using several screens to pull out marginal signals. Those screens buffer the decoded text long enough for me to look at all of them and make a decision about what is correct. By this time the small display on the K3 has scrolled away. If on the other hand you had an overlay of text** on the P3 display I now have it buffered long enough to add it to my decision path as another set of data from a decoder that has different characteristics than my other decoders (MMTTY, 2Tone, hardware modems, etc.) A feature like this would seem to have a broader audience than for SSTV, but perhaps I'm partial...;) ** I would overlay the display with white text over the color waterfall so that I can still see waterfall history behind the text.

Re: [Elecraft] K3 Receiver Protection
The simplest get you there now solution is to simply disable complimentary bands in each K3. Set up the left radio for 80-20-10 and the right radio for 160-40-15, for one example. You didn't buy Steppirs to exclude bands on each radio, but this will give you protection now while you pursue one of the other suggestions. (Obviously, avoid using direct frequency entry to change bands...)

The environment was not well controlled and I'm pretty sure my receiver was damaged during a band change. On the last day of the operation I was calling CQ on 12m and getting no response. Turns out everyone was calling me but I was hearing almost nothing. On my bench I checked it using an XG2. The 50uV setting gave only S3. I then did a full parameter initialization and then tried to calibrate the RF gain using the K3 utility. The utility reported that there was not enough signal to perform the calibration. I also have an XG1 so I tried that. Same result. I tried turning the pre-amp on and off, which did cause about a 2 S unit difference as might be expected. The attenuator also caused an audible difference but not a useful S meter reading. One might suspect that I've blown out one or more of those PIN diodes before the preamp.

Re: [Elecraft] Advice on 6 meters...
Hi Phil, tune up your hex beam and start listening on 50.125. Also there are beacons between 50.060 and 50.080. Also watch for spots on your favorite cluster. But most importantly call CQ once in a while on 50.125 ssb. Sometimes you'll find a dead band is really open. You can also try CW around 50.099. This will get you started.

Re: [Elecraft] rtty via cw paddle
hi Todd - As I understand it, the K3 when transmitting RTTY via CW paddles does not send diddles - rather, it stays in a constant state until you give it a character via the paddles and then it sends the character. Some decoders and some decoders under some conditions do not respond well to this because the decoder gets out of sync - the start time of the second character is not an integral number of character periods from the first character. These decoders sync with the character cycle in an attempt to reduce errors. Most encoders send diddles - a non-printing character like LTRS sent over and over - to help the decoder maintain character sync when there is no printing character to send. A great explanation of this can be found here: http://www.aa5au.com/gettingstarted/rtty_diddles_technical.htm I probably have some detail of this wrong but I'm pretty sure the gist is correct. 73 jeff wk6i On Thu, Dec 19, 2013 at 9:23 AM, todd ruby t...@ruby-wine.com wrote: I tried working ZS9MADIBA today and he kept coming back saying my settings must be wrong because I was not printing correctly.

hi Dave - That was me, not Ted. No worries. Sometimes it hard to sort out. The full QSK idea sounds worth trying once you get it all working. Since most of my contesting is RTTY I hadn't considered that. The interlaced CW and phone transmit sounds crazy but could work - as long as it switches cleanly (as you noted). You could model it to hear how it sounds by rigging a CW signal to selectively mute a received phone signal. I don't have a clear idea on how to do that (as I type) but I bet someone here does.

Re: [Elecraft] Dueling CQ During Mixed Mode 10 Meter Contest
Sounds cool, and as noted is something we can do at least for RTTY, and might work for other modes and mixed modes. But given that you have to listen between CQs, that's a long time between CQs in each mode: CW-listen-phone-listen-CW-listen-phone... I think you'd be better off just calling a tighter cycle in one mode at a time, or using true SO2R with a second radio/antenna (if possible). Just my opinion. But that said... you would set up Writelog for two radios, and configure the Ports menu as two K3s on the same control port. Then in the entry windows L and R you can select the VFO and mode for each window.

Re: [Elecraft] K3 - getting a sub receiver - filter suggestions + dvr
hi Joe - I'll just add that your 2.7, 400, 200 sounds perfect for what you enjoy doing (CW, data, casual SSB). Unless you have identified a specific need for another filter that would seem to make sense. If you do want to try another filter, consider installing the Sub with 2.7 and 400, and put the other filter (like the 2.1 or 1.0) in the Main. That would give you two matching filters for diversity and two more filter for other conditions. Just a thought. - jeff wk6i On Sat, Nov 24, 2012 at 6:58 PM, Don Wilhelm w3...@embarqmail.com wrote: Joe, The filter match or not match question does revolve around your decision about diversity mode. How many times are you in QSO when QSB becomes a problem? The answer to that question is the real decision point for a casual operator. If your answer is that QSB is never or seldom a problem, then you do not need matched filters in the SubRX. OTOH, if your answer is that sometimes or frequently you experience QSB on a signal that you deem important enough to complete the contact, then you need to consider filters that match those in the main K3. 73, Don W3FPR On 11/24/2012 12:31 PM, Joseph Carter wrote: Greeting all. Between my birthday and Christmas my wife has OK'd the purchase of the sub-receiver for my K3 (#6623).

I note form Frank Cady's book that the primary reason for having the filters the same is diversity reception and that do not need to be the same. Right now finances only allow 2 additional filters. So I have been giving it some thought - would it be reasonable to put say a 1,0 filter and a 2.1 filter in the sub or perhaps match the 400 and add either a 1.0 or 2.1? I realize that my operating style influences this - I am not a contester - just enjoy casual operating and some DX. The other issue would be adding the DVR - I was thinking of getting it just because it looks like it is easiest to install it at the time of the subreceiver addition though I am not sure how much I would use it and if I don't get it - I can probably add one more filter.

I didn't read the reflector for all of the horror stories, but I didn't install mine right away because of work - the same reason I checked out of reading the reflector for a while. I finally did it a couple weeks ago, and did find it to be rather involved - but at no point did I feel like I was out of my depth. I don't consider myself the most mechanically able guy by any means. I will admit that when I saw that the front panel had to be removed, I did groan a little. I remembered that the initial assembly and install had been kinda gnarly. But the instructions were very clear and you only have to remove the items that are strictly necessary. A lot less trouble than I feared! By the time I was done I realized that, in a way, by doing all of the necessary disassembly and removal and re-installs, it was kind of like getting to build another radio.

Re: [Elecraft] K3 selectivity display?
hi Barry - Look at the owners manual for the Display page (in my copy here rev B1 it is on page 12). On the lower right of the display are 7 digits, which are used to display a multitude of things, normally the VFO B setting - but also the CW decode and parameter changes. Just sitting there the K3 does not display the BW, but if you turn the WIDTH knob this lower right display will show you the setting as it changes. This is also the case for the POWER setting and many other settings. When you stop turning the knob the display reverts back to VFO B (or CW or DATA decode if you have that enabled.) 73 - jeff wk6i Barry N1EU wrote: Is there any numeric indication of the K3 rx bandwidth on the display?

Re: [Elecraft] K3 selectivity display?
hi Barry - just based on my limited contest operating, the trapezoid seems sufficient to remind me of where I am with BW and shift. Also, the XFIL display helps because you know what you have installed in each slot - for example if XFIL4 is 400Hz, I know when XFIL4 is lit that I am less than or equal to 400, and the trapezoid gives relative BW size from there. Hope I am making sense, it would be much easier to just show you! - jeff wk6i Barry N1EU wrote: Thanks for all the clarification. It's good that bandwidth is displayed at adjustment time, but it would be great if there were some way (eventually?) to display it full time. Seems like in cw/ssb contesting and dx'ing, it's a parameter I want to be intimately aware of. I realize the work-around will be to adjust it in order to read it. -- Jeff Stai [EMAIL PROTECTED] Twisted Oak Winery http://www.twistedoak.com/ Winery Blog http://www.elbloggotorcido.com/ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 selectivity display?
hi Craig - three things: 1. The manual advises you to order the filters from widest in XFIL 1 and go narrower from there. I think this is good advise, to keep it easy to remember where they are. You can order them any way you want, this is just a recommendation. 2. I don't think you will move filters very often. It is a lot of screws to remove since both the bottom and top covers have to come off. I think 95% of the time you are just adding a new one into an empty slot. 3. I understood that additional filters are planned, including variable filters, which would further complicate the display if not using the XFIL notation. hope this helps! - jeff wk6i Craig D. Smith wrote: Also, the XFIL display helps because you know what you have installed in each slot - for example if XFIL4 is 400Hz, I know when XFIL4 is lit that I am less than or equal to 400, I'm still a couple months away from my K3, but this kind of jumped out at me when I read the K3 manual. Why should I need to remember what roofing filter I installed in each slot? Besides, the filters might be swapped from time to time. My personal preference would be to see the nominal roofing filter bandwidth displayed rather than the FL number. To me this would be much more convenient. Is it just me, or am a missing something? Would be interesting to hear from Eric/Wayne on this design decision as well as the preference of other users. 73 ...

Re: [Elecraft] K3 CW set up
I set up my K3 for RTTY and CW especially with the 8poles and 400 and 250. It depends what you want for CW - do you want to isolate signals or is a wider passband your normal procedure? I can tell you that the DSP does a very nice job narrowing the BW to isolate signals down to 100 or even 50 Hz (nice for isolating the response of a weak VO1 from the QRM of calling stations, for example.) But when you cross from 450 to 400 or 300 to 250 and the narrower roofing filter kicks in it is like a brick wall slams down. You really can hear the difference. Reducing interference from close stations is imperative in RTTY, I'm looking forward to trying it out in the next RTTY contest. I've also ordered the 1.8KHz filter for phone contests - especially SS phone! I have the 1.8KHz roofer for the FT1000D, it'll be interesting to compare them. hope this helps - jeff wk6i -- Jeff Stai [EMAIL PROTECTED] Twisted Oak Winery http://www.twistedoak.com/ Winery Blog http://www.elbloggotorcido.com/ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] k3 observed in SS
K3 #27 was also in the SS CW to the tune of 546 QSOs. I'll post more later, but very briefly: I am totally blown away by the K3. There was a point where I had to separate one signal from another maybe 200Hz or 300Hz away, and call and work him. And I just turned a knob and the other signal went away*. And I worked the desired station like it was almost nothing. Damn. I have never operated a radio that was so easy to tune and isolate a signal. You just center it, and crank down the width, and there it is. Damn. - jeff wk6i *OK, there were some clicks - but they didn't matter!

Yes - updating the firmware would be recommended. Several of us early recipients did get an email to that effect right after we got our K3s.

[Elecraft] K3 - very brief first impressions...
Trying to grab a moment to post some first impressions - here goes: - The kit arrived in perfect condition with a complete inventory, no missing parts! Doing the inventory took me about 90 minutes, but I've done a few Elecraft inventories before... - I didn't keep good notes on time, but after inventory it took about 5 hours to assemble the basic K3/10 at a non-hurried rate, and about half an hour to do the alignment and final checks. - On a windows machine firmware download is easy and quick. You install the downloader and it knows how to find the server and check versions. The downloader includes a port test to make sure your serial port is speaking with the K3. Worked perfectly on COM6 (which is more than you can say about a lot of programs...) - There were a couple places where the assembly was a little tight and weird. I will say that if you are forcing it, you may be doing it wrong - and if something won't go where it is supposed to, try other angles until it does. Taking a step back helps too. - If you have built a K2, you can do this. The mechanical assembly is similar enough. - The part of the assembly process that is most like the K2 is installing the KPA3 100 watt amp - specifically the early K2... For the K3, you assemble and test it as a 10W radio before you install the KPA3. Then you disassemble half the rig to put in the KPA3: top and bottom covers, the KNB3, and so forth. Parts everywhere and a pile of screws! You end up making a lot of changes to the back of the radio. Needless to say, I also found this part to be the most fun! (OK, the Front Panel was also a lot of fun to piece together :) - Be sure to run a complete set of TX Gain calibrations on each band at both 5W and 50W, or it won't let you transmit! Operating: - I took advantage of the CQWW phone this weekend and operated phone only to start. This week is CW if I can stop working long enough. I'll do RTTY once my connector order comes in and I can hook up FSK. - The K3 swims in a space formerly occupied by an FT1000D! - During the CQWW I wanted to practice tuning in difficult and closely spaced phone signals. Good news: the K3 can do that! I found by just fiddling with the Width and Shift I could pull out a weak signal hidden by an adjacent strong signal a few 100HZ away. Many voices were readable down to a 1.2KHz width! And the auto notch works like a charm. - The Monitor works well, and once you read the instructions the Mic Gain and Comp are easy to set. My hearing has a little trouble figuring out how much Comp is too much, however... - All my stuff is set up for Yaesu but I had a spare cable for the Goldline which I converted to the Elecraft pinout by moving two wires. (I like using the boom mic because it forces me to sit up straight...) Works like a champ. - Also got it working with the ACOM2000A - the power control makes it easy to nail the 15W necessary to tune the amp the first time. - Made a few dozen contacts in the CQWW just for fun. Busting pileups no problem. A cool treat: I received tonight a video file from V73RY of him working me! I think he just did some video of some contacts and decided to share them with the stations he worked - but now I know what the K3 sounds like in Tonga. That's all for tonight - any questions, fire away! 73 - jeff wk6i -- Jeff Stai [EMAIL PROTECTED] Twisted Oak Winery http://www.twistedoak.com/ Winery Blog http://www.elbloggotorcido.com/ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

David Ferrington, M0XDF wrote: I have an HM10 dual I'm planning on using with my K3 - did you find any issues with setup for a Goldline.

I plan on using the ProSet-K2 from the front mic connector and the HM10 on a boom in the back. I think the Proset will need bias (does it?) and the HM10 not - I haven't figured out from the op manual whether the bias is settable on a per connection basis yet? Yes - you can set bias and gain *range* from the main menu separately for the front and back mic inputs. You do have to set which one is active, and you do have to set the gain level from the knob on the front panel *I think*. It wasn't a concern of mine so I don't know if they save the value when you switch between front and rear connector. The ProSet-K2 does need bias and you can set that separately for front and back connector.

Is there any reason why they weren't made part of the radio - or why I shouldn't put them in when I get my K3? (Assuming of course I can get into that part to do so...) The K3 accepts open collector(or open drain) to ground as inputs, or can be driven with 0 = x = +5 volts. Some stations use RS232 levels (which can be as high as +/- 25V) for direct FSK. Such levels need to be converted to 5 volts for the K3 digital inputs. Further, RS232 specifies a 1 as -3 x -25V and a 0 as +3 x +25V, so a polarity inversion (in hardware or software) is also required. hi Lyle - I appreciate that - but I believe that in 2007 the chances are pretty darn good that those inputs will be driven by a station computer, and that serial port is pretty well known - kind of like the serial port for controlling the radio, right?

Re: [Elecraft] N6XI NAQP RTTY July, 2007 with K3
hi Don - I'm confused. Open collector FSK inputs have been around for at least 20 years, probably longer. Radios have already been slaves to that particular way. What I'm saying is let's make it easier to get on FSK using a standard DB9 cable, and not require the user to build a special cable. In this aspect, the K3 is already locked in the past! And I'm afraid my skill set has never been up to the micro-surgery required to build circuits inside a connector shell a much better place for circuits is safely inside the chassis. 73 - jeff wk6i ps: I predict that RTTY, PSK, CW, and horseback riding will experience no significant changes in the manner in which they are performed in the next 20 years. :) Don Wilhelm wrote: As a counter to Jeff's perspective, I find that similar things which are integrated inside the radio will slave that radio to one particular way of providing that function.

The exception is FSK, which is on the ACC connector. In the present incarnation, driving this line from a PC requires two external parts (one garden-variety NPN transistor and one resistor). I used MMTTY with this interface during NAQP this weekend. But one nice thing about the K3 is its modularity. Both the main I/O card and its audio and digital daughter boards can be easily changed to meet future needs. If for example we added an FSK interface to the digital daughter board, you'd be able to upgrade it very inexpensively, and installing it would take about 2 minutes. Also, we plan to design an external general-purpose I/O unit that would connect to the ACC jack. It would provide pre-wired connectors for use with various PC interfaces, transverters, the KRC2, etc. 73, Wayne N6KR --- http://www.elecraft.com -- Jeff Stai [EMAIL PROTECTED] Twisted Oak Winery http://www.twistedoak.com/ Winery Blog http://www.elbloggotorcido.com/ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
