Re: [Elecraft] KAT500 lost serial comms - try factory defaults?
Hi all, A follow-up on my problem: today I’ve opened up the belly of the KAT500 and have done some testing. With no USB cable connected and the KAT500 powered up, the Q1 drain voltage is 2.39V, where I would expect 5V. Also the gate voltage is 2.30V, where I would expect it to be floating. With the power off, I’ve measure the drain-gate resistance. It’s 5.5 k ohms. Oops! My conclusion must be that Q1 has failed. So now I’m about to learn how to SMD components, hi hi. Thanks for your help so far. 73 de Frank PA4N > On 4 Dec 2020, at 17:35, Rick Bates, NK7I wrote: > > Frank, > > I would start with a complete power removal (not just off) to the KAT500 and > the computer (unplugged from power).

[Elecraft] KAT500 lost serial comms - try factory defaults?
Hi all, I’ve used my KAT500 with pleasure for many years, but recently a problem has arisen: I’ve lost the serial communication feature. I’ve already swapped the KXUSB cable with another one (home-brew) so I’m pretty sure it’s not the KXUSB that’s gone kaput. And the PC is doing USB comms fine (e.g. the USB interfaces to my K3), so I guess it’s not the PC or the USB port either. I’m contemplating trying a KAT500 factory reset. But two questions arise: 1. Can I do a factory reset without having the serial comms working (so: can I do a factory reset other than from within the KAT500 Utility)? 2. What antennas are enabled after a factory reset? (Question 2 is because I have multiple antennas connected to the KAT500, and if the factory defaults would be that only ANT1 would be enabled, I would lose functionality until I’ve got the KAT500 repaired…) Hope the collective wisdom of the group can help me out. 73 de Frank PA4N __ 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

I haven't made any measurements myself, but I do believe there must be some error in your numbers. If RX draws 20A and TX at 100W draws 80A, that means 60A x 12V = 720W input power to create 100W RF output. The other 620W must be dissipated into heat, which, I guess, would melt the K3 over time :) There clearly must be an error somewhere. Also, 20A on RX seems way too high for me. The K3 by itself draws 2A on RX, IIRC. Add an extra 1A for the P3 and the KAT500 maybe, and we're still missing 17A. Was your measurement device faulty, or do you have an error in your maths? 73 de Frank PA4N __ 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] [K3] Disappearing VCO error
Hi group, For some months now, I had the same intermittent problems as Ian: after the K3 has been running for a few hours, it stops working with ERR PL1 (and PL2). The next morning, after cooling off, things are back to normal. Up to yesterday, I was always able to make this issue go away instantly by opening up the K3 and giving all cables going to the KREF3 board a twist. But not yesterday... Thanks to Ians email, I tried removing the KREF3 board, and removing and reseating the oscillator. I also gave all connectors (they were a bit oxidized) a very light scrub with fine sandpaper and then wiped them with a cloth with some anti-corrosive spray. After building things together again and doing the synthesizer re-calibration, my K3 now is back in working order. 73 de Frank PA4N On 28 okt. 2010, at 14:41, Ian White GM3SEK wrote: > Yesterday morning, I wrote: >> >> After the K3 had been running for a few hours yesterday evening, just >> listening to the bands, it stopped working with ERR PL1 (and PL2).

Re: [Elecraft] K3: CW in SSB mode broken?
Hi Gary, group, Elecraft support, I think I have found a strong correlation between CW in SSB not working and the QRQ setting. Here follows: To make CW in SSB work: set CONFIG:QRQ to OFF, power-cycle the K3. To break CW in SSB: set CONFIG:QRQ to ON, power-cycle the K3. 73, Frank PA4N At 21:36 31/01/2012, Gary Hinson wrote: >Hi Frank. > >I have the same problem: CW in SSB no longer works on K3#2887 running >firmware 4.39.

Re: [Elecraft] K3: CW in SSB mode broken?
Gary and others, Yes, I momentarily saw it working okay on 6 meters when I did a brief transmission on that band. Unfortunately, as I don't have an antenna for 6 meters, the K3 encountered a high SWR there. And now it outputs only about 5 watts on each band (also in CW mode) when I've dialed an output power less than 12W. If I select a power level over 12W, so the KPA100 should kick in, I get no output whatsoever. So maybe I broke something now. :-( Or the cryptic bug has manifested itself in the CW mode too. Any ideas whether I could do a software reset of the radio? Fingers crossed here now...

Hi Ken, No, I think not. If I assert PTT and speak, I see plenty output power. If I switch to CW mode and make CW, I see plenty output power. So it cannot be that...

[Elecraft] Slightly OT: Open-source CAT software available on sourceforge.net
Hi all, I just wanted to let you know that I've just uploaded my CatPad software package to the Sourceforge open-source community. CatPad is a software program that provides soft buttons which, if pressed, send CAT commands to your radio. This way you can send macros to your transceiver with a single button press (you may know this from the K3 Utility, or from K-Keys). CatPad also supports X-Keys hardware keyboards (currently only the 58-key keyboard shown at http://www.ymouse.com/xkeys/xkpro.php ). CatPad is available at http://sourceforge.net/projects/catpad/ . It needs a Java run-time environment (1.4 or higher) and as such should be platform-independent. For use with an X-Keys hardware keyboard, one needs a proprietary DLL, limiting the use with a hardware keyboard to Windows-only. I'm currently happily using the program with my K3, but I'm not doing any active development on the program at the moment. Anyone who wants to take the current source code and develop it further, is free to do so. 73, Frank PA4N __ 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] [P3] Additional P3 display idea
Hi all, This may have been suggested before, as I recall there was a thread on additional uses for the P3 display, but I haven't been able to find it in a search. What I would very much like, is that the AGC curve would be displayed on the P3 screen: on the horizontal axis the input signal in dB or S points; on the vertical axis the output signal. The AGC curve could then either be the actual curve, or a modelled version showing at the least the four important areas (horizontal part on the left, then the area with 1:1 slope, then the area in which AGC slope can be influenced by adjusting CONFIG:AGC SLP and finally the hardware AGC area). If the currently received signal would be displayed on the horizontal and vertical axes (maybe with a 'drop line' up to the displayed AGC curve and another going left to the vertical axis), it would become very visible what changing PRE, ATT, RF Gain or the various AGC config settings do to an actual input signal condition. E.g., one would see how the difference between a signal and the noise would increase on the output axis when reducing RF Gain, or when increasing the steepness of the AGC slope. This could also help in explaining what really happens, in case the "the K3 is a noisy receiver" thread comes round again... I'm curious whether I'm the only one wishing for this addition, and whether this idea is at all possible, given the P3's available processing power... 73, Frank PA4N __ 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] K3: overload protection with multiple rigs on same band?
Hi, First: happy new year to all! At PA6Z contest group, we're thinking about using 2 K3's in the upcoming CQWW 160 meter contest. This will be the first time we will be using two rigs on the same band. Of course, we're planning large antenna separation and we'll perform tests and take power measurements in advance, but still we're a bit anxious about possible harmful power levels at the antenna inputs. If I have read the documentation correctly, the K3 has carrier-operated relays on every *receive-only* antenna input, but not at the transmit antenna ports. So, what about this scenario: The first K3 is in receive mode. Its operator has just accidentally hit the 'RX ANT' button, switching the main receiver's antenna from the beverages on the RX ANT (which has C.O.R. protection) to the vertical on ANT 1 (which has no C.O.R. protection). Now, when the second K3 starts transmitting, which protection does the first K3 have, in case the antenna separation alone is not enough to prevent reduce RF levels on the ANT 1 input to a harmless level. Should I add outboard protection to the ANT 1 port, switching it to GND whenever the radio is not keyed?

[Elecraft] Audio mixer request: A - A and B - B
Hello, I have noticed that the CONFIG:L-MIX-R configuration setting currently has six options: A - B A - AB AB - B AB - AB A - B A - AB The keen reader will notice that option 5 equals option 1, and option 6 equals option 2. This is probably a (cosmetic) bug. Instead of correcting this flaw by removing options 5 and 6, I would love to have the following settings for options 5 and 6: A - A B - B This would enable me to implement an elegant AutoHotHey mono/stereo toggle for my SO2V K3 (people doing SO2R with N1MM may know the mono/stereo toggle as that what happens when you push the back-quote (`) key). (Currently, I must use an ugly workaround in my AutoHotKey script in order to achieve the mono/stereo toggle: in mono mode, I set CONFIG:L-MIX-R= AB - AB and then set the RF gain of the receiver that must be muted to 0 and the other RF gain to max. While this does work, using the script I cannot use the RF gain front panel controls in their intended manner, thus reducing the number of options that I have to combat strong signals at the upper range of the K3's dynamic range...) 73, Frank PA4N __ 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] [P3] another idea
Hi, I also use the SPAN feature very much. I have it often set to wide for checking out whether a band is open at all, then move it down to quite narrow when I encounter a pile-up and want to look at the details. I would be much helped by the option to assign "SPAN nn" to a function key. This way I could program one function key with "SPAN 10" and another with "SPAN 200". 73, Frank PA4N At 15:30 03/09/2010, Craig D.

[Elecraft] [P3] and latency
Hi all, I'm loving my P3! I don't know whether this has already been posted in one of the latency posts, but when I send multiple CAT commands to the P3/K3 combination in quick succession (e.g. "FA00010102000;MD7;"), then the second command is missed by the K3. When I switch off the P3, both commands do make it to the K3. 73, Frank PA4N __ 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] [K3] MD3; or MD7; command changes VFO B filter settings
Hi all, I have noticed that when I send an MD3; or MD7; command to my K3 (which sets the VFO A mode to CW or CW REV respectively), the VFO B filter settings (selected filter, filter shift and width) are changed to the values that are currently active for VFO A. This happens with both 3.77 and 3.79 firmware. VFO B must already be in CW mode for this phenomenon to occur. Can anyone reproduce this? 73, Frank PA4N P.S. Maybe this phenomenon is a side effect of the following. In general, the MD command only acts on VFO A. (The MD$ command is the equivalent command for VFO B.) However, if VFO A and B are both in CW mode and you send a MD7; (CW REV) command to VFO A, *both* VFOs are set to CW REV. Apparently, the normal / rev setting applies to the whole K3, not just one VFO. This makes sense. However, I wouldn't expect *all* VFO A settings to be copied over to VFO B when an MD3; or MD7; command is issued. __ 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] K3: L-mix-R
Hi, In addition to Arie's remarks, I would like to be able to select these options in the L-MIX-R menu: A-A B-B If these options are in the L-MIX-R menu, I can use the MN111 and MP commands to set the audio mixing to: main receiver only (A-A) or sub receiver only (B-B). It may look silly to want to select these options, but during SO2V contesting it is sometimes very handy to be able to listen to one receiver on both ears and completely mute the other receiver. 73, Frank PA4N P.S. Currently, I have implemented something similar by using the !bec3; and !bed8; commands, but sometimes this results in very loud audio.

[Elecraft] [K3] N1MM SO2V and slow TX focus switching?
Hi group, This weekend I've for the first time tried out N1MM SO2V with my K3 with sub-receiver, in the ARRL DX contest CW. The combination works great. There is one peculiar thing, though. When RX focus is on one VFO and TX focus is on the other, and I press a Fn key, N1MM will move TX focus to the VFO where the RX focus is. This does work, but the timing is awkward: - I see that N1MM switches TX focus (the red dot moves from the one entry window to the other, and on the K3 I see the SPLIT symbol turn on or off [depending on whether the TX focus moves to VFO B or VFO A]) - Then nothing happens for about 1.5 seconds - Then N1MM sends the message stored in the Fn key that I pressed What's causing the 1.5 seconds time delay? Any pointers? 73, Frank PA4N P.S. When I manually move the TX focus to the VFO having RX focus (using Alt-Left arrow or Alt-Right arrow) followed immediately by an Fn key, transmission starts immediately. (And yes, the radio is ready for transmit: I've many times switched TX focus manually using this method, followed by F4 (=PA4N), and each time the other station got my call okay; if the radio wouldn't have been ready, I'd except the other stations mistaking for e.g. GA4N). __ 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] AFSK A not working, while DATA A is!?
Hi, Most of my operating time, I do CW, but sometimes I do some RTTY QSOs. Today, after what must have been a couple of months, I felt an urge to fire up MMTTY again, so I tweaked the necessary controls on my K3 and on my PC soundcard. But no transmit output?! The PTT is asserted and the receiver is muted, but no transmit output and no monitor output. I rechecked all controls and referenced my notes, but nothing wrong was found. After experimenting a bit more, I found out that everything was working fine when I changed the DATA MD from AFSK A to DATA A! Now I'm puzzled: as far as I know, these two modes use exactly the same inputs and controls... Can anyone help me out? What setting or control can be the cause of this?

Re: [Elecraft] [K3] Macro control of AH-4 remote tuner (and other projects).
Hi Glen, Having a remote tuner, integrated with the K3 would be great... I'm currently at work, so am recalling from my head. I think you can achieve steps 1) through 5) by a hold on the TUNE front panel button. Holding TUNE will set power output to the power specified in the CONFIG:TUN PWR setting. IIRC, pressing and holding a front panel button can be done from a macro with a SWHnn; command. Steps 7) and 8) are performed by a button tap, ending tune mode (SWTnn;). Thus, your problem is reduced to step 6). I think the current macro capabilities don't include reading the accessory socket and acting on a certain condition on it. I'm curious whether Wayne has a good idea on this matter.

Re: [Elecraft] Any solution to the audio blast issue yet ?
Hi Gary, I think Enno was making his remarks here on the Elecraft reflector because of an earlier remark that *I* made on a Dutch K3 email list, and that he was referring to the audio blast that *I* encountered. I was in a CW QSO on 20 meters at the moment the audio blast occurred. I probably had bandwidth set to 400 Hz, using my 400 Hz filter, and may very well have had the NR on, probably at setting F1-1. NB most probably was off. I don't recall having adjusted any controls just before. At the moment the audio blast happened, I was in QSO with DP1POL and was sending my report at that very moment. Although the blast startled me, I did have the wits to continue sending my report, before pulling off my headphones and switching the rig off and on in order to stop the sound. AF GAIN was set to low. This may explain my relatively cool reaction, as I have heard from others here on the reflector that had only one thing left in their minds when the blast occurred: get them phones off my ears! Hope this helps a bit. 73, Frank PA4N At 21:17 25/09/2009, Gary Hinson wrote: > > I wonder what the status of the audio 'artifact' or blast is. > >Hi Enno > >FWIW I have been installing and using the latest Betas as they are >released.

I switched on the noise blanker and noticed that I could only adjust the DSP NB; the second line said "IF N/A". I am sure this worked some time ago, but as I don't regularly use the noise blanker, I can't say at which moment it stopped working... Has anyone experienced this before?

Re: [Elecraft] K3 Subreceiver ANT selection doesn't work - always uses the AUX antenna
Thanks to all people who responded on and off-list to my questions. I've looked at the K3 schematics and have come to the conclusion that the problem most probably is that the digital signal driving the subreceiver's MAIN/AUX relay isn't arriving at the subreceiver. I'm going to check the subin ans subout boards to see whether all pins are connected okay. Merry christmas to everybody! 73, Frank PA4N At 01:15 25/12/2008, Barry N1EU wrote: Frank R.

Re: [Elecraft] K3 Subreceiver ANT selection doesn't work - always uses the AUX antenna
Barry, Thanks for your information. Is the mechanical click when switching between MAIN and AUX also if you have the CONFIG KRX3 set to ANT=BNC, or only when using ANT=ATU ? According to Willis 'Cookie' Cooke, K5EWJ, the switching is in the KAT3 only, and the KAT3 is of course out of the circuit when using the BNC connector as the subreceiver's aux antenna input...

Re: [Elecraft] K3 Subreceiver ANT selection doesn't work - always uses the AUX antenna
Barry, Thanks for your suggestions. Indeed, when I toggle BSET ANT I see "MAIN" and "AUX" alternately. You mention a possible faulty relay. Should there be an audible relay click when toggling BSET ANT I between "MAIN" and "AUX"? When I do that, there is no relay click whatsoever... 73, Frank PA4N At 16:18 24/12/2008, Barry N1EU wrote: Frank R. Oppedijk wrote: > > Hi, > > I've just installed my KRX3.

I assume you alternately see "MAIN" and "AUX" displayed when you toggle the BSET ANT switch and even when "MAIN" is displayed, you're certain that you are listening to the AUX antenna.

[Elecraft] K3 Subreceiver ANT selection doesn't work - always uses the AUX antenna
Hi, I've just installed my KRX3. All went okay. Although I do have a KAT3 installed, I chose the subreceiver's alternative antenna to be the BNC one. If I've understood correctly, pressing BSET followed by ANT allowes me to switch the subreceiver's input between the main receiver's antenna and the BNC antenna. But, irrespective of whether I've selected MAIN or AUX, the subreceiver always uses the AUX antenna. Any clues as to what could be wrong? 73, Frank PA4N --- drs. ing. F.R.

[Elecraft] K3 problem with distorted audio on AM receive
Guys, I'm experiencing a strange behavior on AM receive of strong medium-wave broadcast stations. My K3 is equipped with the FM roofing filter in the FL1 position. It uses this filter for AM receive. Before the problem occurred, I had set VFO A to 1.008 kHz by direct frequency entry. There's a strong (S-9+40 dB) broadcast station there. At that moment the sound quality was good. Then I moved the VFO A dial a couple of kHz and then moved back. This led to the audio becoming very distorted. I could only undo the distortion by re-loading firmware. (I've noticed this problem with the 2.63 firmware, but I see it also with the 2.58 amd 2.45 versions...) Some further investigation learned me that the amount that I can move VFO A before the problem starts occurring depends on the settings of the DSP filter: (1) With LO=0.00, HI=3.00, FC=1.50 and BW=6.00, the problem occurs as soon as move VFO A more then 2.0 kHz from the start frequency of 1.008 kHz. (2) With LO=0.00, HI=2.95, FC=0.45 and BW=10.00, the problem occurs as soon as move VFO A more then 0.90 kHz from the start frequency of 1.008 kHz. Has anyone else experienced this? Any ideas as to the cause of it? 73, Frank PA4N P.S. Another strange thing, that may or may not be related and which I don't understand: why isn't the DSP BW value displayed equal to HI - LO ? Can anyone enlighten me? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K3 #1851 is (mostly) alive!
Hi all! Another K3 has been built! K3 #1851 was ordered on 17 June, shipped on 30 September and was delivered and subsequently built today, 3 October. It's a K3/100, with KAT3, KBPF3, and KXV3. It has the stock 2,7 kHz, FM and 400 Hz filters. The KRX3 and accompanying filters are on back-order (expected in about two months). All calibrations and tests passed, but while trying the rig out on 40 meters, a nasty problem turned up. Transmissing at full power let some of the smoke out. I understand the desired operating practice is to keep the smoke inside at all times. After removing the top cover and doing some more tests at reduced power (30 to 50W), I found out that one toroid on the KAT3 board is getting very hot. It is the blue toroid, possibly labeled K16 (can't quite see) which has 3 windings on it. I'm guessing this toroid is part of the circuit sensing the reflected power. The problem occurs only when transmitting on 40 meters into my antenna (a 2x24 meters doublet), using the KAT3 in AUTO mode. The MFJ-949E external ATU sits in-line, connected with about two feet of coax, but is switched to bypass mode. Interestingly, the MFJ does show a very high SWR (1:6 or worse), while the K3 shows a perfect 1:1 match! The problem with the heating occurs only on 40 meters; on other bands it stays cool. Still, on these other bands, the external tuner shows high readings too. When transmitting into the MFJs dummy load, both the K3 and the MFJ agree that the SWR is perfect. Does anyone know what could cause this? FWIW, I am still using the factory-supplied firmware (MCU 2.38 and DSP 1.90).

[Elecraft] KX1 ATU low power indication
Hi all, Does anyone have any idea about the possible cause of the low power reading by the KX1 ATU? Thanks, Frank Hi, After having been off the air for about a year (moving house; other interests) I have recently fired up my KX1 again. When tuning up a random length of wire, I noticed that the output power indicated by the KX1 ATU was only 0.4 to 0.5 Watts (while SWR was good: 1:1.0 to 1:1.1). I attached a 50 ohm dummy load and hooked up my oscilloscope and saw a nice 24V peak-to-peak voltage on key down. That's 1.4 Watts and IIRC not bad for a battery-powered KX1 (battery voltage indicated by the KX1: 8.5V on receive, 8.4V on transmit). Why then the low power indication by the ATU? I have already taken the unit apart and have resoldered all solder joints on the ATU PCB, but to no avail. Does anyone have any ideas?

Re: [Elecraft] KX1 Frequencies Between Bands
Ha! Matt, now that you've added the statement about turning power off, I think I know what you are experiencing. See http://qrp.kd4ab.org/2004/040101/0036.html . If you tap the BAND switch once before powering off, I expect your KX1 _will_ remember the frequency.

It also seems to only happen when I am running on external power, but leave the power plug plugged in with both the KX1 and the power supply off.

[Elecraft] Balun for KX1 - doublet combo?
Hi, I've been lurking on this list for about a month now, so I guess this is my official "hello" to the group. (Great group, BTW; excellent posts; am learning a lot here!) In the meantime I've bought and assembled a KX1 and am now thinking about which antenne should accompany it on my upcoming holiday to the Alps... I'm considering buying one of those DK9SQ telescopic masts (as soon as I've got a definitive answer about the mast being RF absorbent or not; I want to be able to use it to put up a vertical too) so I can put up a doublet antenna in inverted vee mode. I don't like the 3 dB loss from 10 meters (that's 33' for you non-metric people out there) of lightweight RG174 coax, so I'm contemplating feeding with open wire. Now the big question: how to connect the symmetric open wire feeders to the KX1? a) Don't bother; just plug one wire into the hot side and connect the other side to the case b) Use a balun c) Something else. If b), then what configuration would you use? How small a toroid would keep up with the torturing that it might get in such a high SWR environment?... Thanks in advance for all the help!

Hi Al and others, I've bought KX1 #1166 from the European Elecraft distributor qrpproject.de, roughly around the same time. Mine came alive yesterday evening. It's a very nice rig indeed! Because of the mediocre conditions, I have only worked some contacts in the Field Day contest, up to 2000 kilometers, but it looks like everything is working quite nicely. I must still add the 30 mtrs board and the ATU, and I await the paddle option from qrpproject.de that was out of stock. I'm really trying to get those finished before I start my summer vacation in 3 weeks time. It must be fabulous to lie in my tent in the dark, in some lonely place in the Alps, enjoying CW contacts on my KX1. This is going to be great! BTW, I wonder how many more KX1s live in Europe. I think there are some in Germany and Austria, but not many more and none in the Netherlands, as far as I can see. We might try a sked while you're in Spain, Al...
