    I have a Yaesu FTM-350R that is used as a backup rig in my radio room and it has been working fine up until the other day when it randomly developed an issue. The receive signal strength on the "Main" band is all of the sudden very low and the receive signal on the "Sub" band is normal. It doesn't matter if I select the right or left side, UHF or VHF, the "Main" band RX is always low compared to the "Sub" band. I have tried different antennas, different coax, and even did a master reset and still get the same results. Looking through the menus I don't see an RF gain of any kind. Anyone else had an issue like this? Suggestions before I send it in?

    I'm going to take a very very very wild shot in the dark. A somewhat common problem with the Yaesu VX7R was one of the IF filters going bad. Perhaps something similar with the FTM350R.
    It would give same symptom, main band fine and sub-band deaf or vice versa. I have a dead sub-band on my VX7R at the moment

    Did you ever find out what the problem was?
