[Premium-Rx] Racal RA 6790

[Doug Millar]

Dear List Members,
	I have a 6790 with the LF EPROM's in it and the LF reception is fairly 
good. I understand that they had a later modification of the radio that 
included some add on boards that made for better LF reception. Does anyone 
have any info on the addition or schematics? I think I have access to a set 
of boards, but no information.
	Any help appreciated,
