[Kenwood] Kenwood TS-850

[k0bx at arrl.net]

Hi Mark, this is a common problem with the TS-850.  The replacement board cost 
about $11.00.
My website has detail instructions on this problem.

Hope this helps.

Hello all! My name is Mark, W4TGB.

I own a highly reliable TS-850 that has just developed a power output issue.

At somewhat random times, when I key the transmitter in RTTY or other full
carrier mode, the output power will go to full output and then drop off to
nearly zero within about 3 seconds and then back to full power.

In some cases, the rig will go to full power, drop to near zero and then
back to full power followed by another drop to near zero and then to full
power... repeat...

Has anyone else seen this issue? Any thoughts on a repair?

Thank you,
Mark
W4TGB
