Just saw this, Bill,
I guess nobody commented?
Sounds like something is about to get worse inside. Probably good you noticed it when you did. [No, never had that happen.
I think we always used Mosely STL stuff.
Snow about gone for the summer yet?

Before sending off for repair, anyone have rapidly fluctuating RF output from an analog 950 MHz TFT transmitter?

 

The UNLOCKED light on the front panel is not coming on, and it sounds really nice and clear on the air in spite of fluctuating output.

 

I just replaced both RF module cooling fans, one had died.   But it is running nice and cool and the RF output is fluctuating between 3 and 6 watts.   Long before a fan died I have seen the RF fluctuate between 5 and 6 watts.   Reflected is zero.

 

I know TFT went out of business but support is still available.
