Hi, Max - 

I'd go for the mods that improve on the solid-state circuits.  Because of the 
period when these radios were made, many of the early solid-state circuits that 
were used in the C's have had significant improvements - particularly the audio 
chain.

I owned a couple of C-Line sets (one early and one late) and both had the 
Sherwood audio amps - which I consider to be worthwhile.  There was another mod 
that may not have been Sherwood that involved the third mixer and placing an RF 
choke there (IIRC, it was in the cathode circuit, but we're dealing with a 
25-year-old memory here...) - it applied only to the late-production and got 
rid of much of the hiss in the audio.

Bear in mind that a lot of those mods turned the C-Line into contest-ready 
radios, which - if you're only operating casually - will not return as much 
value.

I used my C-Lines in several CQWW contests and they definitely held their own.

73,

Subject: [Drakelist] R4C Sherwood mods


I am thinking about doing the full works Sherwood mods on my R4-C. Which are 
the best to do?  I don't mind how far I go with this, I just want the best 
receiver for my money, I would like it for Top band use but I know it will be 
good for all frequencies however 160M is where I want to go.
