I have no knowledge regarding repairing your KPA1500. The KPA1500 is very inefficient at the power levels that you are using which may be causing your RF deck failures. Perhaps the KPA500 would be better suited?

First, I experienced 2 back to back OVR 61 - LOW GAIN freq 10120 inp 7W fwd 40W refl 2W swr 1.5 9A 23C adc169 power ratio 6 and then a single FLT 61 - - LOW GAIN freq 10120 inp 7W fwd 40W refl 2W swr 1.5 9A 23C adc169 power ratio 6 After that no error indications BUT I first observed that it took double the input power to get to my expected normal output power and Then audio reports that said I had RF on my signal (when the KPA 1500 was being used). Running barefoot audio was normal. Any ideas? I generally run the KPA1500 in the range of 200 watts (30M) to 700 watts (normally around 500 watts) Disappointed....This is the 3rd failure ( 2nd for RF deck) of my KPA1500 in less than 2 years. 73 -- Bruce, WA3AFS ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
