[Icom] Need help/suggestions on IC-2710H problem

Sun, 17 Feb 2002 21:26:43 -0800

Hi Al,
     What is your high power output on 440 MHz?  If it's not okay, then
start by measuring the supply voltage inside the radio while keying at
high power.  Be careful to use a voltmeter that isn't effected by the rf.
 (an analog meter preferably).  Work your way back towards the power
supply source.  You may want to use a beefier power connector arrangement
like I did. Fuses tight in their fuse holders?  If the high power 440
output is normal, then?  
Good luck,  Bill, W7ERH
