Is anyone using solid-state amps at a competitive multi-multi station? Which? Any problems? 73, Jeff K8ND _______________________________________________ CQ-Contest mailing list CQ-Contest@contesting
Hi Jeff, I have been watching the specs closely as the SS technology has improved. So far no solid state amp is a clean as the single band 8877 amplifiers at 1500 watts that we use at K3LR (PI-L outp

Hi Jeff, I dont think right now is the right time to make such an evaluation. Consider the state of the market. LDMOS technology is now making itself present in the amateur radio mainstream. This is

Jeff, You may want to chat with K9CT. He is supposedly testing the new 4O3A amps. Solid state clearly offers great flexibility due to the instant band switching. The key to a M/M operation would be e
All great points Ria, I am really looking forward to radios and SS amplifiers that use the adaptive predistortion. As you mention - that possibly will make a huge impact in TX signals being cleaner.
I have been using home brew SS amps at my 8P5A station exclusively for the last two years. The flexibility and increased operator efficiency are a big advantage. As such, I am a true believer for thi
And, there ought to be lots of used tube amps on market now, as many of us switch over to SS amps. One of mine will be, for sure. 73, Scott K9MA -- Scott K9MA k9ma@sdellington.us ___________________
Ive used three models of SS amps here. The dirtiest of them all is the Tokyo HyPower 2.5. Next up is the SPE 1.3K, which uses a single LDMOS. Cleanest is the Power Genius XL (2 LDMOS) which is under
As I said, I am a believer, but the tradeoffs are more real than you allow While the LDMOS are more rugged than the MRF150 style parts, and a I have a jar full of 150s to show for it, they are still
Tom has great experience and knows what he is talking. He is using an amplifier that he built himself. We focused on designing a modern amplifier that has all the necessary specs to satisfy everyone
Interesting post, Tom. From the youtube videos that I saw a year or so ago I thought that LDMOS were nearly indestructible. Transmitting into no antenna, a broken antenna or a wrong antenna will even
