[Premium-Rx] Racal RA 6790

[Mark S. Holden]

I'm not sure what else is involved, but they replace a mixer, and the better version includes a preamp.

On the LF eproms, you need to be careful - I bought a set for mine, and the radio would tune low, but it failed BITE, and some filters weren't detected. 

I'm guessing they made slightly different versions of the eproms to account for minor revisions to the basic radio.  Obviously the ones I had were close to correct - most of the radio worked.
