I have a 3 year old FT-2500M. All has been working until last week. Let me
tell you the problem and see if you might have an opinion of a solution:
1. Receive Ok
2. Transmit - Full output and then NOTHING. Right in the middle of a
sentence, output to zero.
Then after a minute or two, full output again, may last the whole qso.
I first thought it might the high SWR on the antenna causing the shutdown. But
the antenna checked ok, and I moved the rig in the house and put it on the
station antenna and later on a dummy load. Same problem. Hi/med/low power
setting made no different.
The 3 things that come to mind that could be the problem are:
1. BAD PA.
2. BAD antenna relay
3. BAD SWR circuit.
Anyone have any ideas? The PA is $90.00. So Sending it to Yaesu, postage and
parts would exceed the cost of a new rig.
Also if anyone has a circuit diagram that they could send me I would appricate
it.
