I think I have seen this discussed before, but I have not found it in the archives. So point me in the right direction or if you have the cause and cure please pass it along. The KPA500 Ser. No. between 1K & 2K or about 10 years old. It has been in daily use without a problem until this faithful day. I have not been able to do a full check yet because I changed computers sometime back and I no longer have a RS232 on the computer, so I ordered the necessary part from Elecraft.
What I am seeing ( using FT8) is no output on 6M, on the HF bands the power increases in steps 50W then 60W then 70W and on the next cycle it will start at 60W then 80W, 90W, etc. In a few cycles it might get up to 500W, but it varies as to which HF band I'm on. I'm thinking is it's microprocessor brain got scrambled with the RF. I can't check until I get the cable, its on order. If you had this problem, was more than a memory flash needed. Maybe a few parts replaced, etc? Did you discover any preventive measures? If so, let me hear from you. 73,Terry, KQ5U ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
