Title: Muting Racal RA6790 Post by: N2GHX Ken on June 01, 2017, 11:02:30 AM Greetings:
Does anyone know the procedure to mute the Racal RA6790? Can't locate Gary Wingerd anymore... Thanx Title: Re: Muting Racal RA6790 Post by: KL7OF on June 04, 2017, 12:57:43 PM Gary told me that there is no good way to mute the 6790...I am using an antenna relay to disconnect the antenna and It worked well for quite a while...however, I still managed to fry the input board. I need to repair it as soon as I can figure out how to repair it... any ideas? thanx and gud luk
