RACAL RA6790/GM-13 RECEIVER WITH A6A2 (F-RAM) Memory Adapter Board
RACAL RA6790GM
This is the RA6790/GM-13 AT&T Receiver S/N 9908 has the A1 RF Amplifier with MUTE and  the RS232 A6A1 card installed. This unit now has a brand new A6A2 card installed with the (F-RAM) Memory Adapter Board, this unit has no battery & no RAM chips 5101 needed because the F-RAM is installed. The 5101 chips will not get corrupted when the caps go bad and you will never have to replace the battery and the battery will not leak causing the card to go bad. This is a must have upgrade that I will be installing in all of the units that I refurbish.
Unit has been fully refurbished & aligned by Gary E. Wingerd, I have installed NEW MODE & FREQUENCY Displays, has LED Board, NEW A6A2 with F-RAM Memory Adapter Board, NEW Handles, the 6 mechanical filters are 7883-6 LSB, 8771 USB, 7883-1 .3 KHz, 7883-2 1 KHz, 7883-3 3 KHz, 7883-4 6 KHz and Jumper for the last slot that gives 20 KHz.  I have repaired the A2 with new caps, A3 with new cap, A7 with new caps and 1 10 ohm resistor, A10 power supply has all new filter capacitors, A4 card has  a new audio IC installed and 2 other IC’s.  New control knobs, new handles, new disc on the A9 card as well as new MODE and FREQUENCY Displays & A6A2 mating connector, repaired the audio output cable, installed all missing hardware, fully aligned the unit and cleaned the unit.
The front panel is not perfect; it has some marks from years of service. Unit works well and has great gain.
The receiver comes with all internal covers installed and the outside covers have been reversed and Dzus buttons reinstalled. I will ship box in a box with packing peanuts to give the receiver the protection it needs.
