[ICOM] IC-2100 issues.

[Jerry Kessler]

Ken,

Carefully examine the connection of the fused power cable to the 
radio power receptacle for any deformed or poor contact.  The spring 
tensioning on the individual terminals may be required to improve the 
connections.  A poor connection can result in heating, which can 
further aggravate the intermittent operation.  Also, check the 
connection on the other end of the power cable to the DC source.  It 
seems like the OT's radio works but just has some intermittent 
problems.  The radio draws significant current on TX, which will 
stress low voltage DC connections.  Check those connections first 
prior to more invasive inspection or testing.
