Hi! I have hade my k2 about 14 years with number 4503 and it been a pleasure to build and operate it but now I got problems with distorsion on the TX audio.
It will usully work fine when it been resting over the night but after a while the distorsion slowly comes. I t start with the base in the audio are reduced and then the treble are cracking up. It sounds like you driving a audioamplifier just alittle to hard. The problem is the same with thek2/100 or when it removed from the k2. I have used a 2 tone signalgenerator and loked with a scope att the signal after the ne602 and after the 10w amplifier and it looks fine to me but the bandwith of the scope is just 15Mhz so I might be missing something. I have replaced u5, Q1, D2and some capacitors on the ksb2 board, tried to find any bad soldering but no luck. Can it be a bad capicotor in the ssb filter or in the Tx signal path? Grateful for any advise. -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ 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]
