    Steve:

I made no recent changes in wiring, but I'm convinced that the problem was 
in the transfer box, so I'll tear into that sometime, but right now, I'm up 
for celebrating Christmas and the fact that if I have any extra money, I 
won't have to spend it on rig repairs.

>> Hi, all.

>> Believe it or not, I think I've found the problem with the low output
>> power
>> on my IC746.
>>
>> Based on a comment I read in a E-ham review, I connected the Ic746 up to
>> the
>> new Samlex 35-amp power supply I got for my new TS480, and guess what:
>> Output power was within a watt or two of 100 watts on both my talking sWR
>> unit, and on the radio's power meter when connected to a resonant antenna
>> with a 1.1 to 1 SWR reading.
>>
>> So, now, I'm thinking something might have gone south on my old 
>> dependable
>> Astron RS35 power supply that might be giving the rig insufficient power
>> voltage or something like that.
>>
>> Has anyone heard of similar results?
>>
>> Merry Christmas to all on the list, and thanks for putting up with this
>> latest round of troubleshooting efforts.
>>
>> That's the life of we hams--always something to challenge us.
