I'm avoiding it now! My KPA1500 died for the second time since it
arrived last September. I contacted service last Thursday and, per request, sent them my configuration information. Nothing has been heard since. Now my "old" KPA500 and KPA500 are back in line and working fine! That appears to be a good fix as they've never let me down.

Hi Mike,
Wow! I apologize for the problem. I believe we reviewed your config file and fault log on Friday and we are authorizing return of the RF deck at our cost and will send you prepaid UPS shipping label on Monday. I will stay on top of this to make sure it proceeds quickly. I will take a closer look at the file myself and will follow up with you later this weekend via direct email to go over what I find and also review the operating conditions etc that led up to the failure. In any case, we will dig into this until we fully understand what caused the problem and resolve it for you. Regards, Eric elecraft.com _..._ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
