Hi All,


During some time now, I have been trying to locate on the internet 
information on mods for the R4C, in particular for the product detector,
the mixers, as well as the RF/IF stages.

I have found some 30 references from power supplies, audio amplifiers
and of course, the Sherwood publications.

I also have all the issues of ham radio here as well as most of QEX 
going back to the start.

I believe that over the years, there must have been quite some traffic
about these subjects.....?

I have a R4C ( S/N 26000 )that I like to bring up to a state of the art 
receiver mainly because of the low phase noise characteristics of the 
PTO, still hard to beat for the amount of money I paid for the R4C.

The level of phase noise is important for IF applications.

If you can help me on the way, please contact me direct.

Regards

Rein, W6/PA0ZN
