[Elecraft] K2 control of Icom PW1 via KRC2 band decoder
Hello, Has anyone been able to control an Icom PW-1 amplifier from the K2 using the KRC2 band decoder? THe KRC2 worked beautifully with my old Hercules II but lacks a conversion to the Icom band specific information that the PW-1 needs. I know the Microham Decoder will do it but at $330 there has to be a simpler way using the KRC2 and a conversion circuit. Any ideas, Tnx, Ralph W1ZK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] re kx1 weak receive
I have had good experiences peaking my KX1 using an AC voltmeter on the audio out. Tune to a place with no signal or use an RF noise generator. Also check the sensitivity of your headphones; you should have something north of 100 dB per mV.

[Elecraft] K2 Encoder - bare wires?
I'm building K2 # 5422 - and just finished the Control Board, and the Front Panel board. Assembling the FP board to the front panel and encoder, etc. K2 Manual calls out cut 4 hookup wires, 1-1/2 long, remove insulation . Are they talkiing remove insulation from each end of each wire, or making the 4 wires BARE? I already messed up one IC install - which took a solder sucker removal operation - don't want to go that route again! I wanted to thank all this list's members for the great help and advice you've given me already in the K2 # 5422 build.

[Elecraft] Computer control issues - unreliable firmware?
I recently completed my K2. I assume that it has the very latest firmware. Although it works fine with k2Remote, it doesn't work reliably with any third-party software that I've tried. I've tried the latest version of dxLab commander, HamRadioDelux, and even purchased HamStationExtreme. Comander won't even connect with the K2. HRD keeps stalling when updating the frequency display. The current release of HSE doesn't appear to work. I'm waiting for an update. As far as I can tell from research I've been able to do, there are firmware problems in the K2 that make the interface unreliable. Elecraft says they don't have any room in their program space to add any flow control. Does anyone have any information about this problem or comments about other control software?

RE: [Elecraft] K2 Encoder - bare wires?
Fred, Yes, bare wire is what is called for - I usually just use some of the longer component leads, but the supplied wire works fine, just remove the insulation from a length of the wire and cut the bare wire to length. After the encoder is soldered in, the leads are sufficiently short that there is no danger of them contacting each other. 73, Don W3FPR -Original Message- I'm building K2 # 5422 - and just finished the Control Board, and the Front Panel board.

RE: [Elecraft] Computer control issues - unreliable firmware?
Rich, I am running my K2 with the latest firmware and Ham Radio Deluxe works fine here. If the K2 operates properly with any program (check with a simplistic one, like HyperTerm), then the K2 is responding properly and you can look for the solution in your computer - the answer will be found in how Windows is working with your application. Yes, there is no flow control (and that is not a problem), it is strictly a command/response protocol, but it has always been that way, and it has always worked for me as long as I set up the computer port properly. Try setting the baud rate and flow control for the computer serial port from the Windows Device Manager as well as from the application and see if your responses are any better. If you are using a USB to serial port adapter, be certain you have the proper drivers - depending on how your computer handles task switching for that adapter device, you may find the problem there. 73, Don W3FPR -Original Message- I recently completed my K2.

RE: [Elecraft] K2 Encoder - bare wires?
Yep, bare wires. It took me by surprise as well (yesterday) but I just followed the directions exactly and all was fine. Also, there is a thermistor board that you'll have to build and install, again using 8 bare wires. That operation was a bit of a pain since the board is so small and I have no 3rd hand. When you do that board, keep components flat and your solder joints thin and flat against the board.

Re: [Elecraft] K2 Encoder - bare wires?
Hi Here is a little trick I use when building the thermistor board. After installing all of the components place the board flat on top of 2 thicknesses of the black anti-static foam. Stick the bare wires (I use resistor leads) into the holes on the board and down through the foam to the workbench. Then solder all of the wires on the board and clip off the excess flush with the board. Remove the foam and bend all the wires down 90 degrees so they stick down from the edge of the board much like a resistor pack. The board should then be easy to install on the RF board in the K2 Don Brown KD5NDB - Original Message - From: Darwin, Keith [EMAIL PROTECTED] To: Elecraft@mailman.qth.net Sent: Thursday, March 30, 2006 8:26 AM Subject: RE: [Elecraft] K2 Encoder - bare wires?

Elecrafters others: I am trying to rescue an old KDK-2015R 2 meter FM tranceiver. The crystal for simplex transmit has failed. KDK doesn't support this relic any longer, but I suspect I can order a new one from Int'l Crystal. The XTAL is a 16.9 MHz (fundamental) crystal and measures close to a HC25 size case. I did some measuring and it looks like HC49U size is pretty close and should work as well. I have googled and come up dry.

[Elecraft] KDSP2 low pass and bypass problems
My KDSP2 seems to operate normally except for two problems. 1/ LOW PASS CW (widest bandwidth, 800Hz) No problems when increasing the center frequency up to 1.1 kHz - Spectogram confirms the filter setting. However, setting the center frequency to 1.2 kHz seems to actually lower the center frequency down to 1.0 kHz. Increasing further the center frequency set point results in LPASS being dispayed, but now the filter setting seems to be exactly the same as with 1.1 kHz center / 0.8 kHz bandwith. The pass band is not as broad as expected, the lower frequency is a few hundreds rather than a few tens of Hertz. RTTY (widest bandwidth, 2 kHz) Same problem as for CW. No problems when increasing the center frequency up to 2.3 kHz. However, setting the center frequency to 2.4 kHz seems to actually lower the center frequency down to 2.2 kHz. Increasing further the center frequency results in LPASS being dispayed, but now the filter setting seems to be exactly the same as with 2.3 kHz center / 2.0 kHz bandwidth. SSB Looks ok. 2/ BYPASS MODE The bypass mode can be set to DSP BYP using the menu. However, this does not actually bypass the KDSP2. In CW and RTTY, it looks like a change to a 2.3 kHz center / 2.0 kHz bandwidth filter (same as observed in RTTY LPASS mode). In SSB, it looks like a sharp filter with a 1000 Hz low cut and a 2000 Hz high cut. Any solution to this problem? Thanks in advance.

Re: [Elecraft] KDSP2 low pass and bypass problems
2/ BYPASS MODE The bypass mode can be set to DSP BYP using the menu. However, this does not actually bypass the KDSP2. Please note the current the K2 is drawing (use the DISP button) when in operating mode and in bypass mode. If the current drain is reduced, the KDSP2 is bypassed and the effect is from something else, perhaps the current crystal filter setting. In bypass mode, the DSP goes into a low power mode and the CODEC is mostly turned off, just leaving the analog section operating to pass the signal through. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

H i; Maybe some one can help. I am building K-2 # 5423 with the rework eliminators. I got the unmdules and missing parts but the instructions were not good for installing missing parts. I figured it all out except the 60 meter module. I installed D-19 and 20 before testing and alignment part II. All was fine until VCO control voltage setting. The low and high freq voltages at R-30 were well within range on all bands except 40 meters where it was 7.000--5.51v 7.300--7.91v and sensitivity seemed low on 40. Then I discovered on the K-2 schematic DO NOT install D 19, 20 with out changing C-71 from 82pf to 120pf. I replaced C-71 with the 120pf that came with the rework parts and now 40 is deaf and the VCO voltage is7.93 volts at 7.000 and hardly changes up to 7.300.

Re: [Elecraft] Computer control issues - unreliable firmware?
Thanks, I had a few responses about USB/Serial adapters. Since I've had poor luck with almost every control software program I've tried, I was suspecting the serial adapter or the K2. As you are probably aware, most notebooks no longer come with I/O ports. I've added 8 prolific USB/Serial adapters to control various radios and related devices. They seem to work on everything else I operate, so I was suspicious of the K2. There may be an issue with this particular device and the prolific ports though. I don't mind buying yet another serial adapter. Walmart is on my way home. I'll pick one up and try it. If it doesn't work, Walmart's pretty good about taking stuff back. Thanks for the info.

RE: [Elecraft] Computer control issues - unreliable firmware?
Not sure of the others on this list but EVERYTIME I have ever used a USB/Serial adapter on a USB hub I have had problems. Often it was not recognized upon startup of the PC - it was only recognized when unplugged and then plugged in with the PC On. I had to place the adapter in every USB socket it was ever in and then Uninstall - the device. THEN place in the HUB. The serial adapter ALWAYS had to be in the same HUB socket. I ended up with 6 - 8 serial ports only one of which was any good. Ended up restoring (can only do with WIN-XP) the PC to before I ever bought the @#$% thing. I now only place it in a specific non-HUB USB socket and always the same one. Might be a good idea to put some fingernail polish on the socket/plug.

I got the unmdules and missing parts but the instructions were not good for installing missing parts. I figured it all out except the 60 meter module. I installed D-19 and 20 before testing and alignment part II. All was fine until VCO control voltage setting.

I replaced C-71 with the 120pf that came with the rework parts and now 40 is deaf and the VCO voltage is7.93 volts at 7.000 and hardly changes up to 7.300.

RE: [Elecraft] Rework stuff
Phil, This is one aspect that I would like to see the rework eliminator guys reconsider, but since you have now added D19 and D20 and have changed C71 to 120 pF, do the next step and enter the K2 menu and set D19 to ON - then you should be able to get all bands within range. By the way, the range of voltages allowable after making these changes is between 1.0 and 7.5 volts, but make an attempt to get them all within the 1.5 to 7.0 volt range first. 73, Don W3FPR -Original Message- Maybe some one can help.

[Elecraft] More problems with K2 #5061
Hello again folks, A week or so ago I contacted Gary about a problem with excessive current on Q6 when I was trying to do the 40 meter transmitter cal. Turns out that Q10 was shorted driving the base to 4 volts key down. Replaced Q10 and that problem is fixed. Now, however, the VFO is inoperative. It had worked FB before and the receiver seemed very hot. Now I can hear background noise and QRN but can't tune in stations. The readout changes like it should but the oscillator stays at one frequency. I verified this with an external frequency counter as well as the built-in one and same with a spectrum analyzer. The oscillator is running and it puts out RF as it should but not on a given frequency. With 80 meters selected I get the following frequencies; TP1 7788.6, TP2 4914.17, TP3 12092.17. I checked U6B pin 5 and get the 4V ref, pins 6 and 7 never change their values regardless of turning the frequency knob. Am I overlooking something? Is there some hidden menu I might have activated? I was very careful when removing and replacing Q10 and besides, it isn't anywhere near the affected circuitry. Any ideas? 73, Pat Haynes-K4BEH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] Computer control issues - unreliable firmware?
Actually, I'm designing one as we speak. It's a compound USB device containing a sound card and serial port. I did a proof of concept with the design strung out on my bench. I never used it on the air but the USB side of things worked quite well. The signals on the waterfall looked very good. I tested it with Digipan 2.0, MixW, and Ham Radio Deluxe. I was never able to get my current external USB interface to work with HRD so I was very pleased. I'm purposely designing it to use the Windows-supplied drivers so no driver installation CD is required. This I hope will make it work with a wide range of software programs. However, it requires Windows XP equipped computers. I'm not sure if many people are still using the older versions of Windows. Anyway, I'm designing a prototype circuit board to test it with the K2. If that's successful, the next stage is to redesign the PC board again to get it inside the K2. I just have the base K2 so I need to determine a shape for the PCB that will work inside a basic K2 as well as a fully-loaded K2. I'm sure it's quite crowded inside with all the options. I think I might have to separate the USB Type B connector from the rest of the board in order to make installation more flexible. The design is still in the early stages but I'll be interested in enlisting the help of some testers in the future. If you'd like to help test this contraption in exchange for a completed product when released, then send me an e-mail.

Re: [Elecraft] Balloon as antenna support
Ah yes the kitoon. Had heard of it but forgotten. Seared in my memory instead was two Field Day attempts by my club at balloon antennas, both ending in blow overs. Much overrated as an antenna support. Most balloons of the WX type cannot lift no. 12 antenna wire of a big antenna, or lift it vertically. Of course on a hill as we are, you always have a part of the day windy. The kitoon aims to take the wind and steer the balloon lift so that lay over is not the problem. But then, you are back to the kids and BB guns, too heavy of antennas, and the constant SWR changes as the wire moves around. Required constant retuning, thus losing QSO time in FD.

[Elecraft] K2 Options - when?
Hi - As I just finished K2 #5422 Control Board, and Front Panel ( got good AOK resistance checks) - I'm wondering as I start on RF Board - just how much REWORK is it to add NOISE BLANKER and SSB OPTION to my K2, after the base K2 is completed? Is it a major take-apart operation, to add these options after the base K2 is up and running and all buttoned up in its case, etc.? I guess I'm fearing having to dissassemble circuit boards, and take all stuff back apart - just to add options. I can't imagine having to take the RF PCB back out - once its all in and running.

NOTHING requires pulling the RF board out. The Elecraft enclosures let you get at everything by just pulling individual enclosure panels. The most complicated disassembly is in the front panel where the control and front-panel boards are stacked, and it comes off as a unit. The SSB and Noise Blanker only require removing one part of the bottom cover. Very easy. The only disassembly anyone has grumbled about that I've seen is in removing the part of the bottom cover used for the final amplifier heat sink, since some hardware is attached to it. I have done it many times without any bother, but some folks find it intimidating. The only options that requires you remove that part of the cover is to install the 160 meter option board and, if I recall correctly, the K60XV interface that provides coverage of the 60 meter frequencies available for Ham SSB and an optional low-level interface for the XV50, XV144, XV222 or XV432 transverters.

[Elecraft] Optimum AGC threshold setting
W3FPR's answer (below) to S-meter settings triggered a question: The manual says to set the AGC to 3.80 V, which I have done, but if I wanted to set it for optimum receiver performance, as Don suggests, which way and how far do I go? I usually use the XG1 and check the S-meter with the preamp off on 40 meters - if the AGC Threshold is set for optimum receiver performance, and CAL S Hi and Lo are set the S-meter usually comes right in at S-9 with the preamp off.

Re: [Elecraft] Uses for K1 MCU?
I love it. I have quite a few PICs of various types since I do a lot of designing with them. Yet I, too, have a small collection of the programmed microcontrollers that were upgraded. Why? Dunno... But, if you cut off the legs (and file the stubs down), and drill a small hole in one corner for a small hook, you can then use them as Christmas tree ornaments. My YF (KB4TGE) even has a pair of ear rings made from gold ceramic LM107s that I scrounged many years ago. So those old chips _do_ have a use. You just need to repurpose them!

The 'C' versions of the PICs are not re-programmable - OTOH, if it has an 'F' designation, it could be re-programmed for other uses. 73, Don W3FPR -Original Message- Long ago I upgraded my K1 from firmware version 1.06 to 1.09. I kept the old MCU, a PIC16C77-04/P, but I'm not sure why. If I'm not a programmer, would I have any use for it beyond reverting to 1.06 in an emergency? What have other K1 upgraders do with theirs?

[Elecraft] Re: Uses for K1 [EMAIL PROTECTED]
Scott, As the author of the firmware, I can assure you the best use of that old K1 code is to flatten its pins and put it in a scrapbook, or maybe turn it into a mobile, along with other electronic thingamabobs. (Along this same line, PCBs make nice jewelry.) Seriously, as Don mentioned, the older PICs with a C in the middle have UV-erasable EPROM code store, but no UV window, so they can't be erased. Newer models with an F in the middle have FLASH code store and can be electrically erased. We're gradually phasing out the C parts. There's only one interesting thing you could do with the old code: connect the MCU to a K1 LCD and a couple of switches, and turn it into a 3-digit frequency counter. See K1 front panel schematic. The rest is left to the reader as an exercise :) 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
