[Premium-Rx] Racal RA6790/GM improvements

[DAVEINBHAM at aol.com]

A few days back there was a discussion on improvements to the Racal 
RA6790/GM.

I suggested we post all that information somewhere. Did anything come of that 
?

Yesterday I found something really interesting at 
http://www.eham.net/reviews/detail/488  

It seems there was a VLF/ ELF version of the 6790 that actually tuned down to 
1kHz. 
It had the famous VLF version of the EPROM's, a different first mixer and a 
few other differences from the "standard" 6790. Anyone have any information on 
this ?
Better yet, does anyone have the goodies to convert a " standard" 5790 to 
VLF/ELF that they would part with ? I sure would like to get at least one of my 
6790's to tune down to 1kHz. 

Last question for today. Would there be any interest in reproductions of some 
of the options that were available for the Racal RA6790/GM ? Such as the 
optional RF amplifier, the A5 ISB board, the spectrum analyzer output board, the 
VLF/ELF option etc. I have a small company that might be able to do that if 
there is enough interest. It ain't gonna happen next week but maybe by mid 
summer. It is a ( sometimes ) for profit company. I did the ReCap kits for the 
R-390A through the company for a couple years. The total profits from that venture 
bought a case and a half of Guinness Stout. The profit margin will have to be 
a tad higher this time, say, two cases of Guinness per month minimum.
Anyone interested ?

Kindest regards,
Dave
