No Tim, it is "stable" at all times. Extremely low volume on my local transmitter but blasting away (on my scope) to the grid of the second detector. Doesn't appear to be heat related. I should have been clearer. Each day I turn it on just for a check and for several days in a row it kept coming up lower in volume until such time (now) full volume can barely be heard.
