[Elecraft] K1 in big contest

Hi list, I'm planning to be on vacation in southern spain in cqww cw this year. I wonder if in those crowded bands it is possible to use a K1, which I'd prefer to bring along. I don't want to win anything, just join the test for some hours. - Will I have fun? - Will the receiver handle the crowd

[Elecraft] K2 receiver problem

Hi list, got a K2 from another OM on my workbench. It's got a receiver problem and I just want to make sure I do the checks in the correct order and I'm looking for hints, if available! Thanks in advance! So here's the problem and what I want to do. It seems the receiver runs with "handbrake on"

[Elecraft] WAS: Temperature with KPA100 and XV144

OK, I found out that I put out too much power with my XV144. This is because I did alignment with 12V and later ran the rig with 13,8V. I did two things to nearly solve the problem of overheating my XV144. 1st I realigned power with 13,8V 2nd I disassembled the chassis, removed the heat rubbers

[Elecraft] Temperature with KPA100 and XV144

Hi list, I have run into some minor problems regarding temperature rises with the mentioned devices and like your opinion/solution. 1st, the KPA100. I noticed that even when I only answer some CQs in a contest (CW) the fins get very hot - of course the little fan fights it. Not to speak of CQing

[Elecraft] WAS: K1 Problem with Power Out on 30/40m

Hello all, my problem(s) are solved. Due to circumstances I don't know two things at once happened and made it hard to find the problem: - first I had a cold solder joint on the filter board in the 30/40 section of the premix bandpass filter which was hard to find and then - second I have a bad

[Elecraft] Elecraft family growing...

Hi elecrafters, as of yesterday a new member of my elecraft family is on the air. Joining my K2 #4309 I built a K1-4 #1985 with KAT1 and KBT1. Made the first contacts with 10m of wire tossed into a bush this weekend. Worked G and LA and some DL with K1 running on internal NiMH 2100mAh with 5W. I

[Elecraft] KPA100 check result questions

Good morning, I'm still in the process of building my kpa100. After my learning process concerning soldering :-) I stumbled upon some voltages. I'm on page 43 in the manual now and got some numbers a bit off the given values (PS is 14V). D13 154V U4 -27.4V TP1 0V J3+ 0.1V Are these numbers ok?

[Elecraft] Control board mod with KAT2 and KAT100

Hi, just read the manual for the KAT100. It states to remove C44 on K2 control board before using KAT100. OK. How does this affect the use of the K2 without the KAT100, with KAT2? You see, I want to switch covers from qrp to qro :-) Thanks Gerhard __

[Elecraft] Two K2 top covers...

Hi, I'm just thinking if it's possible to have two top covers for my K2 and if yes what is there to be thought of? Are they to be changed without problem - just unplug and plug? I currently have the "qrp cover" :-) SPKR, ATU, BAT and KIO and I am thinking about one "qro cover". Merry x-mas to ev

[Elecraft] K2 PLY and keying

Hi, I would like to suggest a minor modification for the next firmware release of the K2. When I press PLAY MSG with no number following the K2 doesn't respond to keying from my paddle. It would be nice if it would cancel the PLAY command and key the transmitter. Until I noticed the behaviour I

Re: [Elecraft] K2 - no TX power problem -- D36 WANTED in Germany!!!

Hi, thanks for recommending another Diode. The vendor suggested to use UF4007 instead of 1N4007 maybe. What do you think? Of course it's hard to get the D36 here in Germany. Any idea, German readers??? I think of getting it at - HAM Radio, - QRP-Projekt - or Elecraft 73 Gerhard --- Don Wi

[Elecraft] Vrms measurements with oscilloscope

Hi, if I signal trace with my oscilloscope and want to know the Vrms values at certain points in my K2... ... is ist correct to measure the amplitude (not peak to peak) of the signal and then divide by the square root of 2? Will I get values I can check against the given Vrms values in the manua

[Elecraft] K2 T3

Hi all, I have a problem. After assembly my K2 (#4309) doesn't have any output at all. So I went examining... I suspect maybe T3 is wrong: Looking at the pictures (appendix, not drawing in assembly section) in the manual T3 clearly has more then 5 turns. Looking at K2 toroid pictures of ac6kw thi

[Elecraft] Resistance Checks...

Hi all, I'm currently building my K2 and am at the first point to measure resistances in the circuits. I'm using a Standard - DMM. Now the problem: When a check should bring up let's say 70-90k and I switch the DMM to 200k it will read abt 40k. Do I switch it to 2M I'll get a reading much highe
