If the XMTR is @ 10 W. at 1st. time to key up. and
then take a dive to 1.5 Watts, being I never seen this unit or schematic, I am
going to guess ..
A componet may not short until it gets x amt of
time the power is present then shorts out or opposite opens up and the pwr.
drops.
Just to add some information...
The upgrade to version 5 employs the Dallas Real Time Clock (DS1216) but it
goes in the U31 socket not the U30 socket
The upgrade does nothing to U30 and re-uses U31 in it's same state only it
goes into the Dallas socket.
Of course U34 is completely

Sometimes you get lucky, and it's only the chip; too often you'll be
checking individual pieces-parts. Those pass xstrs can be a real pain.
Suggestion: put that new chip in a socket -- makes it lots easier the
next time.
Test fixture: swipe a headlamp or two from, say, the XYL's car... 8-)

I am thinking of using LMR-400/600 ultra-flex as

Some one mentioned that there have been some problems with

Has any one experienced any problems with LMR

You would be better off with RG-214/U for jumpers. Or .25" of 1/2" supper
flex.
The problem with LMR 400 or 600 is it will crackle after a while in the
receiver side.
Good luck,

As a troubleshooting technique, you can plug in one pass transistor at a
time and the power supply will work so that you can measure voltage on the
output. I have had strange things happen to an Astron 35 which has included
a single pass transistor shorting out, a resistor in the reference
