[MRCA] PRC-47 parts needed

[Tim]

Hi Steve - tough break....(I don't have a spare T1...)
One thing I advise is to do your initial transmit testing with a 5 amp
panel fuse in the DC power feed versus the stock configuration 20 amp
fuse.  The 5 Amp fuse will permit transmitter testing at the 20 watt power
level and protect the HVPS transistors.  Then go back to the 20 amp fuse
once you've got everything figured out for high power testing...

Anyway, works for me.
