KPA-500 Combiner
Locked
 
|
Since a KPA-1000 or KPA-1500 have not come to fruition..how about making a Elecraft KPA-500 Combiner for stacking either two or three KPA 500's? Sell more KPA500's as required to go with the RF Combiner

Acom has a splitter/combiner for 3 of their 2000A amps.

Looking at specs show SWR <2:1 and 160-10M.
Could live with not having 6M but the 2:1 SWR spec may be unacceptable. 73 de Brian/K3KO On 3/3/2014 06:18, Dr. William J. Schmidt, II wrote: > Done.

Yes....BUT....the SWR is NOT 2:1, it is LESS than 2:1. IMHO you will be hard pressed to find RF circuits that would be less than 2:1 SWR and cover that wide frequency range and if you do, you really need to look into marketing 'wishes' from that company! It can be done, but not at ham radio owners price range. Look at the K3 specifications and tell me what max SWR the transmitter will work into without a tuner? 73, Tom - W4BQF -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of alsopb Sent: Monday, March 3, 2014 7:54 AM To: [hidden email] Subject: Re: [Elecraft] KPA-500 Combiner Looking at specs show SWR <2:1 and 160-10M.

On the other hand we are hard pressed to find a solid state amp that is
happy at 2:1 SWR. I understood the note was <2:1. It would be nice to know what it actually is in the ham bands. 73 de Brian/K3KO On 3/3/2014 13:37, Chester Alderman wrote: > > Yes....BUT....the SWR is NOT 2:1, it is LESS than 2:1.

Speaking of solid-state amps I am a happy SPE 1K FA owner and it says you can go up to 3:1 but it isn't very happy above 2:1. Nor do I run the amp on anything above 2:1. The warranty is also invalidated if you use an external autotuner and it breaks. Still a real nice amp but everything has its pros and cons.
