Hello, all. I have a question regarding my home and mobile setups, which are similar in nature.
In both home and mobile, I have both a 2m and an 11m (CB) radio setup. In the car, the 2m and CB antennas are aboue 2.5 feet from each other and at the house they're about 6' apart. If I have a QSO on 2m, I turn the RF Gain on the CB radio down to zero in an attempt to mitigate high levels of RF coming into the radio, but I recently noticed that the CB's meter was rising to a 1 when I keyed up the 2m radio.
Do I still have to worry about cooking the front end of the CB running my 2m rigs at 10W? The antennas in questiion are correct for their respectrive bands. Additionally when mobile, I have a third radio that I just use as a receiver via another 2m antenna, but I have attempted to shield it from high RF levels by placing an RF limiter designed for SDR radios in the coax.
I'm just curious everyone's thoughts if I could be causing equipment damage or anything better I could do. Will putting the RF Gain to zero actually reduce the RF that is reaching the front end of the CB?
