Carrier on lsb


First thing to check is the frequency of the carrier oscillator. In LSB it should be 7.7985 MHz. If it's much higher than that, this makes setting the carrier-balance trimpot VR7 incredibly touchy. Might check VR7 first just the same.

Best way to check that crystal is with a receiver that has good frequency accuracy. Using a frequency counter runs the risk that attaching a probe will knock the crystal off frequency while the probe is attached.

When you checked this were you running a power mic? If so you might first try turning the mic gain on the radio and mic down. Sometimes when this happens background noise can appear as a carrier. Good luck.
