I set the dead key on AM to one watt and when the radio gets hot, it goes
back up to almost full wattage and modulation sounds "pinchy" according to
reports. I have to then cool it off before it will act normal again. Does
anyone else see this with theirs? Mine is in my vehicle so the temperatures
do get extreme. I find this happens a lot after it's been parked in the sun
for a while. Today I tested my temperature theory by taking the cover off
and holding the radio in front of the ac vent so it would cool off fast. It
went back to normal in just under a minute. Sounds like a weak regulator. I
hope some one has seen this before and knows the solution. I don't have a
schematic for it. :-(
