Anyone had a fault like this. After switch-on the received signal vanishes
after a few seconds to a minute (as evidenced by listening to the local
ATIS). Of course it is a great problem if you are tuned to a not very busy
ATC fequency. Can be restored instantly by switching off then on immediately.
This behaviour is present always below about 15 deg. C. though oddly enough
I have run it in the fridge with no problem ! I know of another
installation with the same behaviour. He has taken to keeping it in the
house. Haven't got anything out of Narco via the vendor so far.
