I picked up a general Washington radio a twin radio to the general Lee 10 meter mobile. When I get new radios in I like to do receive and transmit alignments because I don't know whose been in them before and they're usually off some. The transmit is perfect in this radio I just can't align the receive at all and with a freq counter just plugged into the radio it keeps showing 24 to 29 megahertz just moving everywhere on receive but transmits to my locals perfect and on frequency. Could this be a crystal, ic, or 455if filter problem.
