Manson Labs SSB Converter for R-390/R-1247
\'m selling a Manson Labs CV-1694 SSB Converter. This is similar to
better known CV-591 SSB converter that is used with the R-390 & R-390A receivers. The CV-1694 was designed for the R-1247 receiver which was the high stability version of the R-390A for the Apollo space program. This converter has both top and bottom covers and fits in a standard 19" rack. This SSB adaptor will work with any radio that has a 455kc IF. However, it needs some additional inputs: the 455kc reference signal, a 6.3v filament supply, and a 180v supply (I think). I searched the web to see if anyone had interfaced this with the regular R-390A and found some newsgroups where this was done. Though someone has written "good" on the top cover of this converter, I have no way to test it so it is sold as is. Price is $500.00 plus shipping from zip code 63105. Weight is only 9 lbs. but figure a little extra for double-boxing. I have created a web page with lots of photos: http://www.mindspring.com/~vibroplex/cv1694.html |
