[Elecraft] K2/100 + Icom AH-4 Antenna Tuner?

Hi Does anyone have experience in using the remote Icom AH-4 Antenna Tuner with the K2/100? Does anyone know the signal flow between the KIO2 and the KPA100? Could it be used to control the AH-4? I know what the AH-4 needs. 73 Gert, OE3ZK K2#2200 Member of FOC & HSC

[Elecraft] K2 lowest power output

Hi Don, I do not have any power meter which can measure any RF power output less than 1 watt. Could you please advise the minimum output power level of K2 with the power knot fully CCW? BTW, under the SEC menu of K2, the transverter output (without the installation of KV60) can be lowered

Re: [Elecraft] General SMD Soldering Question

Thanks, Don: I have a larger iron and will try that approach first. I could also have tried to source other caps but instinctively went first for something similar to what was there before. Again, greatly appraciate your advice, 73 Wyn, VR2AX - Original Message - From: "Don Wilhelm"

RE: [Elecraft] K2: Can't get frequency counter to work on TP2

Carroll, Unless you are using someone else's email, it is neat to know that there is another Wilhelm in the K2 family - I started with SN 20 and it is still going strong. If your RF Probe is anywhere near correct, it would seem that you have plenty of RF signal at TP2, so the problem must be in t

[Elecraft] Building the XG-3

While building the K1, I had to come up with a signal source for alignment on 30m and 17m. The Norcal tuner upper for 30m (10116 kHz) works great as a signal source, but I had to resort to a noise generator for 17m. So I figured I could build myself an XG-3, the WARC band signal generator. I

A few recent units have shown problems that at least sound similar to this one. See, for example: http://www.ac6rm.net/mailarchive/html/elecraft-list/2005-03/msg00676.html http://www.ac6rm.net/mailarchive/html/elecraft-list/2005-12/msg00408.html These two, at least, were due to the KSB2 ALC circ

[Elecraft] K2: Can't get frequency counter to work on TP2

Hi, I finished construction of my K2 (serial #5400) last month and all was working well. At the time of construction all of the filter alignment went well. It has been lots of fun... I'm selling my Yaesu. :-) Since then I decided to calibrate the VFO on my K2 to get the frequency better align

RE: [Elecraft] Blown R58 relpaced, still no power out, does anyone have any hints?

Steve, With R58 almost a direct short, there is a possibility that the PA transistors were conducting too hard and caused their untimely demise. But it would be best to check the RF voltages first before drawing any drastic conclusions like that. There actually could be any number of guesses abo

[Elecraft] Blown R58 relpaced, still no power out, does anyone have any hints?

Hi Guys, A few weeks ago I managed to induce a fault into my K2 by transmitting into no load when testing the top band option. I found that R58, the 180 ohm, half watt resitior at the far end of T4 had been damaged and had a value of 4 ohms. So I replaced it and reassembled the K2 and I still

RE: [Elecraft] General SMD Soldering Question

Wyn, If you have the hot air gun or oven and solder paste and know how to use it, by all means go that route, but if not, then just use the Hakko - you will be soldering two widely spaced tabs on the capacitors rather than finely spaced leads like are encountered on SMD ICs. Yes, the Kester 44 wi

RE: [Elecraft] "de-sensitizing" C22

Vern, Use a long slender metal screwdriver that nicely fits into the cap slot and you will find it much easier to adjust. If you are using the alignment tool supplied with the K2, it is too flexible for precise adjustment. If you mounted C22 the right way 'round, the adjustment slot should be gr

[Elecraft] General SMD Soldering Question

This is distantly related to the mainstream of Q&A on this net.I intend to use my new K2 to drive a Icom IC-2KL amplifier. Please imagine for now, there is an intermediate amp between the K2 and the 2KL. One of the twin PA boards on the 2KL ( a backup, I have 2 of them) is unfortunately, smoked

RE: [Elecraft] KPA-100 Problems

Dave, Is this a new KPA100? or have you had it for a couple years? Some (but very few) KPA100s had a similar situation a while back. If it is recent, I have no immediate answers, but if it is older, put the change on it for the increased TR switch voltage (change R4 to 39k) and add a 1k resistor

Hi Guys, I am having problems with the KPA-100. 80m reports of distorted audio, like a vibrating effect associated with it. And even when I have the PO adjusted to a max of 15 watts it seems to transmit up to 60w out. I know it's not RF feedback caused by antenna because I have the same prob
