Re: [Elecraft] Please do a KPA1500

Hi Fred Your looking for a bigger Elecraft amp? Just put two 500's side by side and drive them 180 degrees out of phase and take their output and drive a balanced line to your antenna. Be sure to come back and let us know how it works best for you. Have fun with it. NE7LS

Re: [Elecraft] Please do a KPA1500

Audio processing can create distortion only in the passband of the crystal filters. It may sound varying degrees of awful, but it doesn't cause splatter. You've got to overdrive an RF stage or have that stage drive a mismatched load, or drive it with AGC engaged, or stuff like that to generate

Re: [Elecraft] Please do a KPA1500

The Expert 1.3k is sold with the 15 db restriction. But anybody can do a low power mod and it is legal. ARLL Review (July 16) shows IMD at 1.3 KW level: 3rd/5th/7th/9th (14 MHz, 1300 W PEP): –31/–39/–57/–55 dB. Seems not to be worse than Acom 1500. The IMD as measured are misleading. Take

Re: [Elecraft] Please do a KPA1500

I think a KPA1000 would be pretty popular if priced appropriately. I love my KPA500, but a little extra oomph would be nice now and then. 73, Scott N9AA On 12/31/16 10:39 AM, j...@kk9a.com wrote: Since I sometimes bring my station to the Caribbean, one of the main reasons that I switched to

[Elecraft] Please do a KPA1500

Since I sometimes bring my station to the Caribbean, one of the main reasons that I switched to the Elecraft line was for the size and weight. I have a KPA500 and an it is an awesome amplifier but I would like a little more power at times. I considered the Expert 1.3k that many with similar needs

Re: [Elecraft] Please do a KPA1500

I have Expert 1.3k that I use with KX3 for > 1 KW. The Expert 1.3K also violates the 15 dB gain limitation rule and is a real garbage generator. Expert's own test data in their application for FCC approval showed IMD at -27 dB at 800 W! For your 1 KW, each of the IMD products are probably

Re: [Elecraft] Please do a KPA1500

With a little work, KPA500 can be a KW amp while losing weight. This is by using LDMOS and a commercial PS. But then KAT500 would have to be beefed up to KAT1000. I have Expert 1.3k that I use with KX3 for > 1 KW. The Expert is 21 lbs (lighter than Elecraft) with a 3:1 tuner + 4 antenna switch

That will be a lot of money for only an extra S unit (barely). Just over a 4db gain off the top of my head. It is the first 500 W that count. Mike va3mw > On Dec 30, 2016, at 1:27 PM, Dean L wrote: > > Fred > 500w 》1500 w -It's less than an S-unit increase in

Re: [Elecraft] Please do a KPA1500

Folks, we have not ever formally said we would never do a 1500W amp. We have said at times in the past that we were not doing one at that time, but we never rule anything out. We're always looking for good suggestions and marketing input on what we should do in the future. 73, Eric

Now more than ever there is a need for a 1500 watt amplifier of the quality and function of the KPA500. PLEASE, Elecraft, reconsider your decision to produce a KPA 1500. You could use the front end of the KPA500 as a controller? Fred Serota, K3BHX
