[GCARC] Fwd: [KPA1500] KPA1500 Panic Button: Forcing a Firmware Load

[Jim n2gxj]

It is strange, but 1 hour into a session, suddenly the remote showed the
swr. So i was like, lets turn from standby to active. Lo and behold, i got
it to sow 300 watts out with about 8-9 watts in!
Later, when i connected in that night i remote saw no swr and no power out,
even in standby. But get this - with radio out at. 20w i still completed
qso, even though remote kpa showing 0 out.
