[ICOM] Squirrely IC-751A

[Gary Fiber]

Tom,

If you still have the old ram unit and your magnifying glass handy 
look around the connectors and see if there are cracked solder 
joints. Most times that is the cause with sometimes corrupt ram 
programming.  Also measure the battery and see what voltage its at, 
should be 3 to 3.3 volts.

If you gave the old ram unit the boot oh well.I am just curious.

Glad you got it working.

Something to remember if you power up an IC-751A and you are missing 
memories you know you have programmed make sure the mode scan button 
is not depressed. As when the mode scan button is depressed only 
memories that will have displayed information in then will be the 
ones with a mode common to the VFO.
