Hi Ken,

I've hear from a friend it had something to do with the On-Off Switch (but I don't know how possible that would turn the amp off if it is not by pressing the switch).

I bought one last month, but only has five or six hours of use. Nontheless, I'm not phisically pressing any buttons, I use remote control software by HB9ZS instead.

BTW, I've sent an email to service at alpharfsystems.com, asking a few questions about the amp and they replied withing a couple of days. Maybe you can try that (if you haven't yet).

GL.

73,

I have a different strange issue with each of my Alpha 87As that showed up
this past weekend.

1.     One amp goes into standby without an error message and won't go into
the operate position no matter how many times I flip the OPR/STBY button. If
I turn the amp off and wait the longest 3 minutes in ham radio a few times,
the operate light will come back on and the problem goes away for a few
hours.

2.     The other amp gave me intermittent #20 errors, filament current
greater than 3.5 amps, for the first few hours it was turned on. It never
did that during the contest.

Any experience with these types of conditions? Suggestions?
