[Elecraft] new KPA 500 question

I finally succumbed to temptation and ordered a KPA 500 which will arrive tomorrow. This may be a question that can't be answered on this reflector but I thought I would try. I have an HF 2500 Commander, the Palstar version, which I have been using with the k3 and other radios. I am not sure

Re: [Elecraft] new KPA 500 question

bruce , I also have two amps...which I flip between using two topten a/b switches. works like a charm... used to be a TT titan and a Hercules... now an ACOM and the kpa500 easy to automate or just put a little toggle led array see bottom center of pix

Re: [Elecraft] new KPA 500 question

This will depend on the input relay or other switching circuit used in the Commander. Some QSK circuits use a small reed relay in the input and a vacuum relay for the output. In that case it's possible that 500-600w from the KPA500 will be too much for it. Others use a pair of vacuum relays,

Re: [Elecraft] new KPA 500 question

If you are 20db over S9 with the KPA500, you can be 25 to 27db over S9 with the Commander in line. The path is clear... Sent from my iPad Chuck, KE9UW (Jack for BMW motorcycles) On Dec 18, 2012, at 11:45 AM, Bruce McLaughlin bmcla...@bex.net wrote: I finally succumbed to temptation and

Re: [Elecraft] new KPA 500 question

I agree, the path is clear -- it is obvious --- sell the Commander as 5 to 7 dB is not worth having extra stuff around to fool with. As said by a person with a growing interest and desire for QRP contacts. 73, phil, K7PEH On Dec 18, 2012, at 12:28 PM, hawley, charles j jr

Re: [Elecraft] new KPA 500 question

Sure could have used the extra 5-7 db when chasing the recent ZL9 Dxpedition on RTTY from the East Coast. 73 DE Brian/K3KO On 12/18/2012 20:31, Phil Hystad wrote: I agree, the path is clear -- it is obvious --- sell the Commander as 5 to 7 dB is not worth having extra stuff around to fool

Re: [Elecraft] new KPA 500 question

I disconnected my Alpha 87A when I got the KPA500. Working DX doesn't seem any more difficult after learning to watch the pile-up with the P3, but I don't use SSB, where one might notice a difference. 73, Tom Amateur Radio Operator N5GE ARRL Lifetime Member QCWA Lifetime Member On Tue, 18 Dec

Re: [Elecraft] new KPA 500 question

I hate to be a contrarian, but the path is not quite so clear. That 5 to 7 dB can be the difference between making a contact or not making a contact, especially on the low bands. We're not always talking about the difference between S9, plus 20 or 25, but the difference between S0 or S.5, or

Re: [Elecraft] new KPA 500 question

I totally agree ... there is nothing clear about that path at all. 5 db is a HUGE difference if you're anywhere near the noise level on the other end, and it is a major difference if you're competing against other weak stations for a contact. Under the right circumstances even 2 db can make

Re: [Elecraft] new KPA 500 question

Ok...I was a little hasty I think. I've never been a contester and didn't consider HAVING to make the contact in adverse conditions. Sent from my iPad Chuck, KE9UW (Jack for BMW motorcycles) On Dec 18, 2012, at 5:05 PM, David Gilbert xda...@cis-broadband.com wrote: I totally agree ...
