I recently got a small linear from a friend to use in the mobile when out on the road working. I hooked it up right after getting it and immediately noticed a problem. When trying to use it on SSB after I am done talking...I will have nothing but static in the receive....my needle is all the way pegged like i am transmitting...but the mic is unkeyed for sure. And the amplifier is making a hissing like sound. The only way to get the linear to stop doing it is to power it off. I right away checked the capacitor in the SSB relay circuit. If i remove the capacitor...the relay just clicks as I talk on Sideband....but no matter what size capacitor i use in the circuit....it does the same thing. I can use the amp fine on AM...but the SSB circuit just will not work as it is suppose to.
Anyone have any ideas?
