For any intermittent in any radio brand/ model, the first thing for you 
to do is the following:

One by one unplug and replug in carefully all jumper cables, flat 
cables, etc. on the rig boards. IF any show obvious corrosion you will 
need to procure some DeOxit contact cleaner and apply as per 
instructions.  This was carried by some Radio Shack stores, and hifi 
stores or ON Line.

If there are band switches with movable brass silver contacts you need 
to place a drop of De-Oxit on each contact area, and rotate the switch 
back and forth.

Usually the above will solve these type of problems.  If not, examine 
all solder joints for correctness of solder melting, shiny appearance, 
wetting, etc.
Examine any antenna contact jacks with spring loaded fingers to grip the 
matching connectors.

TT uses a crimp on miniature coaxial connector that could work loose 
over time, check those.
