[Elecraft] K3 remote issues - launching HRD
I have been experimenting with Remoterig and the K3 for awhile (since early April) after purchasing a system from someone on this reflector. I bought two of the RRC boxes and have had some challenges with getting it working correctly for business travel purposes. It first started with networking issues that change frequently especially since I am using a 3G USB card for remote control connectivity. With that problem solved I now am facing issues with getting HRD and/or TRX manager to launch. I am wondering if there is an issue with the radio RRC box connecting to the K3 and then be able to launch a control program such as HRD from my laptop. I am using 4.51 K3 software. I have gone through the settings many times and have the proper configuration set up from what I can see. I am wondering if I am missing something in configuring the K3 RS232 port or in the laptop. I have a post on the Remoterig forum but thought I would also post here. I am planning to get another K3/100 extremely soon and will be going to a twin setup though I am a bit concerned that my 3G setup might have some issues and the hotel I stay at for business has pretty miserable Internet connectivity.

If I enter it once from the keyboard correctly and then check back again, it will show the missing letter problem. Thus I can set the memories OK (with k3util) but I cannot edit them properly.

[Elecraft] k3util & editing CW memories (linux)
Hi, I am having problems with the k3util program & programming CW memories on linux. I have programmed Bank 1/M1 by keying with a paddle as: CQ CQ CQ DE AA6KJ AA6KJ AA6KJ CQ CQ CQ DE AA6KJ AA6KJ AA6KJ K Then I enter k3util and use Edit CW memories and I see Bank1/M1 as: CQ CQ CQ DE AA6KJ AA6KJ AA6KJ CQ CQ CQ DE AA6KJ AA6KJ AA6K K Note that J is missing from the last occurrence of my call sign. This happens consistently every time. If I save the memory at this point by clicking on save then I really have a missing J in the K3 memory as well. This is not specific to using M1 or the string length. I see the same behavior with M2 with: CQ CQ DX DX DE AA6KJ AA6KJ AA6KJ CQ CQ DX DX DE AA6KJ AA6K AA6KJ K Now the J is missing from the second last occurrence of my call sign. If I use a really short string, for example, just my call sign once, there is no problem. I though that this might be an rs232 transfer issue so I tried lowering the transfer rate down to 9600 (from 38400) but no change. I am using a usb based rs232 adapter and K3util version 1.12.3.28. Also, everything else seems to be working just fine (test communications and other functions). Any clues what is going on?

Re: [Elecraft] OT: Solar Panel Tests with K1 and A123 Battery
Eric, Don't put a solar panel on a battery without a charge controller! I fried a few batteries on a boat I had by going without a charge controller, and all I had was a good 10 W panel. I have been using 45-60 Watts of solar panels for the last few Field Days with 2 K2s, an FT-817, and a K1. The battery has been a size 24, ~85 Ah. On this operation, we have had charge controllers, and our battery has been useful for the entire time. The company that I would have suggested for a charge controller is belly up, but there are a number of sources for marine and RV controller that will work. Additionally, you might try Harbor Freight. They are the folk we got the 45 W worth of panels from. 73, Barry K3NDM - Original Message - From: "eric norris" To: elecraft@mailman.qth.net Sent: Sunday, June 10, 2012 7:18:24 PM Subject: [Elecraft] OT: Solar Panel Tests with K1 and A123 Battery Dear Gang: I'm a newbie to solar power, but I ran some tests today that I think might be of interest to those thinking of solar operation in the field. The story so far: I converted to Buddipole A123 packs for portable operation more than a year ago and have been deliriously happy with them. However, to my knowledge there were no solar charge controllers available for them when I bought them, and so last year, when I first used a solar panel for Field Day, I tried a using a small 5-watt, ancient glass panel I got at a flea market for $10 and plugged it directly into a gel cell. Though it could not keep up with the K2's power demands, it extended the discharge of the battery. To the best of my knowledge, an undersized panel can be used directly with a gel cell. I have read that you do not want to try this with an A123 pack, and I was not going to risk it. Buddipole now offers a solar charge controller for the A123 packs. However, it is currently sold out. I went with a Genasun GV-5 Li 14.2v controller (NOTE: these are offered at different cut-off voltages so make sure you order the correct one-- Li 14.2v for A123 packs). The Genasun controller has the added feature of dropping the battery out from the load when it reaches 12v so you don't damage the expensive A123 pack. I much prefer fail-safe features like this that prevent me from doing stoopid (sic) things. Today I hooked up my K1 (as a pre-test for the K2) to a dummy load, and had it calling CQ from its memory constantly. Using a 5w PowerFilm panel (these fold up small and are great for QRP operations in the field), it would not keep up with the K1's power drain at full tilt, about 7W out,as expected. I then hooked up a 10w PowerFilm panel, and it did keep up with the power drain, essentially keeping the 4s2P pack fully charged as indicated by the Genasun's LED. I disconnected the panel, and drained the battery a bit, then hooked it up again and it reached full charge as indicated by the LED, while still calling CQ. I confirmed this after the test by hooking up the battery pack to a Cellpro 10s charger which indicated the pack was at full charge. I further crash tested the Genasun by disconnecting it from the battery, panel, and load in random order to see if I could destroy it. I repeated this in every different order I could think of, and still it soldiered on. Better it get destroyed now than in the heat of the moment on Field Day. The 5w panel showed about 300ma of charging current. The 10w panel showed about 600ma of charging current. Put in parallel, for 15w, they showed about 850ma of current. Note: If you connect multiple panels in parallel you must use blocking diodes. PowerFilm panels supposedly have these built-in. The Genasun did its job, showing no current from the panel to the pack when the pack was fully charged. This was an "ideal" test, with the panels flat on the ground and near noon. However, I won't be calling CQ continuously during Field Day, either, and so I think this setup with 15W of panel power may be able to keep up with the K2 at 10 watts, given time talking to visitors, eating, and goofing off. Time will tell! Ultimately, having a fully-charged battery near the end of the day means night operations, too, but the need for enough excess panel capacity so that the pack will charge during the day even with the radio drawing power. You'd need more capacity for something other than casual operation. If I had it to do over again, I would have bought a 20w panel for use with the K2 (and eventually a KX3), though they are expensive. A 5w panel might be adequate for a KX1 in the field, but cloud cover, tree cover, limited charging time, and less-than-optimal angle between the sun and the panel all translate into the need for a bigger panel than you might think. PowerFilm sells a daisy-chain cable for hooking two panels together. It is expensive, but it does use their water-resistant connectors. I'd appreciate hearing from others with more experience with portable sola
[Elecraft] KX3 Operating Tip: Using the KXPD3 attached paddle as a hand key
The KX3's attached keyer paddle is very flexible. Normally it is configured for right-handed use (MENU:CW KEY2 set to LEFT=DOT). You can reverse it by setting the parameter to LEFT=DASH. In addition, you can set the CW KEY2 parameter to HAND. In this case both the left and right paddles will function like a hand key. The KEY jack on the left side panel has the same feature, under control of the CW KEY1 menu entry. You can independently set up CW KEY1 and CW KEY2. So, for example, you could use an external hand key at KEY while using the KXPD3 as a keyer paddle, or vice-versa. 73, Wayne N6KR __ 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] K2 hand key problem
Ron, Like other similar problems, we have to determine whether you have a hardware problem or an RF feedback problem. The answer to that question is usually determined by asking you to transmit into a dummy load (with no other changes). If you have normal transmit into the dummy load, then you have to solve the RF Feedback situation coming from your antenna(s). OTOH, if the problem persists when transmitting into a dummy load, then you have a hardware problem to be solved, so post again with the updated data. 73, Don W3FPR On 6/10/2012 7:55 PM, R Thompson wrote: > I was looking to make a contact with my hand key when I ran into an > unusual problem.

Re: [Elecraft] KPA500 Issues
Hi guys!
Seems I found the solution to my problem. I put ferrite cores next to the
amp AND I forgot the PTT line so that was added. Added one to the AC line,
there's two now. Now I'm able to get acceptable VSWR and run 350 watts out.
I never really thought that it was the amp's fault but my installation.
That's good cuz 6 meter prop is in so I'll work a few more Q's today!
I suppose that there is a lesson learned here, ISOLATE your installation
either by distance and/or add ferrite. I was pretty suspect that the
problem was the close proximity to the antennas. FYI, but thanks to all for
your technical support! It wasn't the product, it was the guy (that would
be me) and my installation that was the culprit.
Having said that, does the 500 maybe need a little more RF hardening? Not
a EE major, just asking the question.

Thanks Bob!
I actually did that and added those snap-on ferrite cores. I cleaned up
things a lot! I'm starting to think that there may be other things going
on. I took the advice of others that replied. Things such as using a dummy
load, no problems. I put the amp in STBY and when running 100 watts thru it
the VSWR was less than 1.5 to 1 and forward power was 100 watts (indicated
on the amp). I put the dummy load on the other end of my run of coax and it
was fine. Even with the extra balun and ferrite cores me thinks that it's
either the length of the coax or I have the antennas too close to the shack.
My 6 meter yagi is laterally about 30 feet from the rig/amp and the R8 about
36 feet.
Anyone else have any ideas? Thanks!

The R-8 is a radial-less vertical. Unfortunately it has a tendency to put
all sorts of RF down the coax as the "counterpoise" system is too short
given the wavelengths involved.
You might want to buy a heavy-duty coaxial choke from DX-Engineering like
the

I used a R8 for years and had trouble even with 100 watts of power. I can't
imagine how bad it would be at 500 watts. Your station ground is going to
have to be top notch if you want to avoid trouble.
Good luck!

[Elecraft] OT: Solar Panel Tests with K1 and A123 Battery
Dear Gang: I'm a newbie to solar power, but I ran some tests today that I think might be of interest to those thinking of solar operation in the field. The story so far: I converted to Buddipole A123 packs for portable operation more than a year ago and have been deliriously happy with them. However, to my knowledge there were no solar charge controllers available for them when I bought them, and so last year, when I first used a solar panel for Field Day, I tried a using a small 5-watt, ancient glass panel I got at a flea market for $10 and plugged it directly into a gel cell. Though it could not keep up with the K2's power demands, it extended the discharge of the battery. To the best of my knowledge, an undersized panel can be used directly with a gel cell. I have read that you do not want to try this with an A123 pack, and I was not going to risk it. Buddipole now offers a solar charge controller for the A123 packs. However, it is currently sold out. I went with a Genasun GV-5 Li 14.2v controller (NOTE: these are offered at different cut-off voltages so make sure you order the correct one-- Li 14.2v for A123 packs). The Genasun controller has the added feature of dropping the battery out from the load when it reaches 12v so you don't damage the expensive A123 pack. I much prefer fail-safe features like this that prevent me from doing stoopid (sic) things. Today I hooked up my K1 (as a pre-test for the K2) to a dummy load, and had it calling CQ from its memory constantly. Using a 5w PowerFilm panel (these fold up small and are great for QRP operations in the field), it would not keep up with the K1's power drain at full tilt, about 7W out,as expected. I then hooked up a 10w PowerFilm panel, and it did keep up with the power drain, essentially keeping the 4s2P pack fully charged as indicated by the Genasun's LED. I disconnected the panel, and drained the battery a bit, then hooked it up again and it reached full charge as indicated by the LED, while still calling CQ. I confirmed this after the test by hooking up the battery pack to a Cellpro 10s charger which indicated the pack was at full charge. I further crash tested the Genasun by disconnecting it from the battery, panel, and load in random order to see if I could destroy it. I repeated this in every different order I could think of, and still it soldiered on. Better it get destroyed now than in the heat of the moment on Field Day. The 5w panel showed about 300ma of charging current. The 10w panel showed about 600ma of charging current. Put in parallel, for 15w, they showed about 850ma of current. Note: If you connect multiple panels in parallel you must use blocking diodes. PowerFilm panels supposedly have these built-in. The Genasun did its job, showing no current from the panel to the pack when the pack was fully charged. This was an "ideal" test, with the panels flat on the ground and near noon. However, I won't be calling CQ continuously during Field Day, either, and so I think this setup with 15W of panel power may be able to keep up with the K2 at 10 watts, given time talking to visitors, eating, and goofing off. Time will tell! Ultimately, having a fully-charged battery near the end of the day means night operations, too, but the need for enough excess panel capacity so that the pack will charge during the day even with the radio drawing power. You'd need more capacity for something other than casual operation. If I had it to do over again, I would have bought a 20w panel for use with the K2 (and eventually a KX3), though they are expensive. A 5w panel might be adequate for a KX1 in the field, but cloud cover, tree cover, limited charging time, and less-than-optimal angle between the sun and the panel all translate into the need for a bigger panel than you might think. PowerFilm sells a daisy-chain cable for hooking two panels together. It is expensive, but it does use their water-resistant connectors. I'd appreciate hearing from others with more experience with portable solar power for the Elecraft rigs. I have no financial relationship with any of the companies listed, though I am still seriously in love with Elecraft :-) 73, Eric WD6DBM __ 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] KPA500 Interface with Kenwood TS-590
You don't need the rig and amp to communicate for auto band changing to occur. The KPA500 will sense the frequency of the RF and change automatically. No need for the cable. But, if you desire to interface the TS-590 and the KPA500, make sure the serial cable is plugged into the (XCVR) port on the back of the amp and in the "Radio" menu, set the parameter to "serial." It defaults to K3. 73, Scott, N9AA On 6/10/12 3:19 PM, Doug Person wrote: > Hi all, > > I was attempting to demo my KPA500 with my friend's new TS-590. > Everything is fine except I can't get automatic band change to work. > Serial port speed is set to 19.2 on the radio and amp.

Re: [Elecraft] P3 External Monitor Displaying CW at HamCom Yesterday
Since Eric probably isn't back home yet, and I was there helping them with the displays, I'll answer this as best I can. It was some new code for the P3SVGA that iwios still in test and hasn't been released to the public as a Beta version yet. The CW, PSK and RTTY decode is not being done in the SVGA option, but in the K3 itself. It's the same data that shows up in the VFO-B area on the K3's LCD display, just being passed to the P3's SVGA option and displayed on the big screen. The USB keyboard interface is already included in the P3SVGA option but the code is still being worked on. I wasn't told how soon this would be out in the world, but the display of the K3's decoded data is at least working. I believe, and Eric will correct me if I'm wrong that even though there won't be a keyboard interface without having the SVGA installed in the P3 that eventually the decoded DATA will be able to be displayed on the P3's screen. That's about all the info I have that I feel comfortable passing on right now and once Eric gets home and rested up from the show (which was, by the way, a good one.) Lots of interest in all things Elecraft and especially in the KX3 and the P3 with the SVGA adapter. Eric's wife Lerma was pretty much kept busy taking orders for all sorts of stuff. It was nice that the Plano Center convention venue had open Wi-Fi available. Of particular interest in the KX3 camp was the ability to use an i-Pad and a little device called the i-MIC along with an APP to take the info from the KX3 and display it on the i-Pad making it into a very nice high resolution panadapter. Nuff said for now as I'm sure Eric will have lots more to say about Ham-Com when he gets rested up.

Re: [Elecraft] KPA500 Issues
I came in late so may have missed a point or two. The R8 is an end fed half wave vertical and the 'matching box' includes a common mode choke. It has a very low angle of radiation. If it is on the same vertical plane as your station, the antenna will 'hose' it with RF (have that situation here, so I'm waiting for the KAT500 to heat up the dipole; it's 50' away). Placing the R8 directly above your station puts you in a null, which may give enough lower signal strength to keep things content and the added height won't hurt either. This presumes that the 'matching box' contents are still effective as the ferrite has been known to crack. It is time to pop open the side of the black box and see how it looks inside (spider webs arcing, wires burned/intact etc.). I'd look for a cracked ferrite, which may show good SWR at low power, yet when it gets RF hot may do something completely sideways. What happens when you turn the Yagi away from your station (most nulls will be ~45 deg off of the rear)? When you add ferrites to the cables in the shack, don't forget that RF can enter at ANY point; audio, USB/serial etc); filter everything. 73, Rick wa6nhc -Original Message- From: Kent Tiburski Thanks Bob! I actually did that and added those snap-on ferrite cores. I cleaned up things a lot! I'm starting to think that there may be other things going on. I took the advice of others that replied. Things such as using a dummy load, no problems. I put the amp in STBY and when running 100 watts thru it the VSWR was less than 1.5 to 1 and forward power was 100 watts (indicated on the amp). I put the dummy load on the other end of my run of coax and it was fine. Even with the extra balun and ferrite cores me thinks that it's either the length of the coax or I have the antennas too close to the shack. My 6 meter yagi is laterally about 30 feet from the rig/amp and the R8 about 36 feet. Anyone else have any ideas?

The R-8 is a radial-less vertical. Unfortunately it has a tendency to put
all sorts of RF down the coax as the "counterpoise" system is too short
given the wavelengths involved.

imagine how bad it would be at 500 watts. Your station ground is going to

Re: [Elecraft] P3 External Monitor Displaying CW at HamCom Yesterday
I was told this was a test of new firmware for the P3SVGA. It seemed to do a fine job of decoding both PSK31 and CW (they had two P3s running, each decoding a different mode), although the signals consisted simply of an endlessly repeated callsign. At one point Friday afternoon we had a total power loss to the exhibit hall. The new firmware was sufficiently robust that it recovered from this unanticipated test. I didn't think to ask if keyboard input was also in this firmware, but I don't recall seeing a keyboard connected to either P3. 73...

Re: [Elecraft] Picked up used K2
Mike, I believe you need to do a good IF filter alignment. There is a change in sidebands for 15 meters and above. due to the placement of the VFO above or below the received signal. You will need the internal counter probe - if you did not receive it with your K2 (and it is not inside), you will need to obtain the parts from Elecraft. I recommend you use an audio spectrum analyzer such as Spectrogram and your computer soundcard to see where the filter passband is placed. Look at the K2 Dial Calibration article on my website www.w3fpr.com - part 3 of that article deals with filter alignment, although you may want to do the whole procedure and have good dial calibration too. 73, Don W3FPR On 6/10/2012 9:52 AM, Mike Bellow wrote: > I just picked up a used K2 and have been checking it out.I think I found > 2 issues with the radio,Receive on 15m,12m,10m is fine sounds good seems > to be right on.On 17m and 20m the receive audio is very sharp not like > the other higher bands,My question is where do I start to get these two > bands back inline correctly?This is my first Elecraft and am very > impressed with it's operation,I actually like the rec better than my new > Ft-950. > > __ 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] KX3 and KPA500
ACC2 IO setting > LO=PTT (input; apply 0 V or ground to activate PTT) > I can't figure out how to set the ACC2IO on the KX3 so that it will key the KPA500 properly. I currently have the >ACC2IO in the off position. When I connect the cable between the ACC2IO and the PA Key on the back of the KPA500 it puts >the KPA500 in a transmit mode. I have to manually put the KPA500 in standby to receive and then Operate to transmit. I >have tried a number of different settings on the KX3 and KPA500 with no success. What am I doing wrong?
