[R-390] R-390a not receiving below 8 MHz

[Larry H]

Hi Gary,  Try v207, also.  And, the mini coax connector (MB) at j221 makes
bad contact sometimes.  And then there's the band switch section s208
rear.   If it's out of alignment or making bad contact, can do it.

Has it worked correctly recently?

Regards, Larry
