I used to have one of those back in 1973 and yes it wasn´t that good. Back then I made a quick fix, I attenuated the signal before 2:nd mixer and amplified it back up again after, 20 dB I think it was.
Understand you dont like to modify it a lot however if you can find QEX Jan/Feb 2006 and read what VK6APH and VK6VZ did with the R-4C, this will make a very good radio. 73 Jim SM2EKM ------------------------ GALE STEWARD wrote:
I recently acquired a C-line in very good condition. I never had one "in the day" and always wanted one. Before the purchase, I asked my friend if the R4C was the later model (5 position mode switch) and he told me it was. As I picked up the radios, I noticed that the R4C was the earlier model (4 position switch). I went ahead with the deal as the price was good. Since I do a lot of DXing/contesting I really didn't want the terrible FET second mixer receiver. I've heard the "old" and "new" versions side-by-side in the past on a band with lots of loud signals and there in a huge difference. I recall hearing (somewhere) that Drake would modify the early R4C's by removing the FET and installing a tube 2nd mixer if the customer requested the change. Does anyone actually know any details of the factory mod? It would be pretty easy to rewire the noise blanker socket to accept a 6BE6 second mixer. Has anyone done this previously? I guess the final question is, do I sell this R4C and buy the later model? This earlier receiver is in good condition and I'm not going to do any mods where I'm drilling extra holes, etc. Since I actually use all of my older gear, I want the best performance out of them that I can get. Any info appreciated! 73, Stew K3ND
