Hello dear friends, i have a strange problem with my GD77 (latest firmware 29th november).
So the problem is that the radio pickin signal on whole VHF band, and show that signal every 2 seconds as if it receiving cap plus frequencie, but there isn't any cap plus on that frequency not even close to it... It also interupting audio when someone talking on VHF.
I already checked settings, and tryed few different things to change, but without any success.
I was wonder if it is bug or i must change something?...
I using Diamond X50 antenna.
GD77 - Mystery signal on VHF
Re: GD77 - Mystery signal on VHF
The GD77 RF design doesn't perform well when using an external antenna. It is very easy to overload the receiver. Especially on VHF. That's sounds like what you are hearing.
There is probably a very strong signal on another frequency.
The only way to fix this is to use an external bandpass filter or an attenuator to reduce the signal level. However this will also reduce the wanted signal.
