I agree 100% about the R4C as I said it's a great rx!!! I wish I had never sold the one I had years ago that I had maxed out. Oh well live and learn!

It also depends upon your operating habits (modes/dxing/contesting/etc.) but the crystal filters and electronic passband tuning of the R-4C give it a big advantage over the B line receiver for operating in CW or SSB contests, weak signal dxing, etc. For general AM/CW/SSB operation the R-4B (or earlier R-4 and R-4A) are great receivers. For most people the standard SSB filter plus the 500 hz CW filter will cover their C line filter needs. Both of mine have the accessory 1.5 Khz, 500 hz, and 250 hz filters but 90% of my CW operating is done with the 500 hz filter. I only have the noise blanker in one of mine but I never use it. I haven’t added the AM filter to either of mine and rarely use the C line for AM but the “roofing” filter in the first IF provides decent AM selectivity and a resistor placed across the open accessory terminals allows AM operation without the accessory filter.

When I went in to place the order Dave had just taken a pristine loaded C line in on trade and I bought it (R-4C with all filters/NB/extra crystals, T-4XC, MS-4/AC4, and mic) for $350. I should have just stopped with that instead of ordering the Yaesu because the FT-980 looked good and had a lot of features but it had a very noisy receiver and a poorly designed internal power supply. The FT-980 shared the same heat sink assembly with the FT-One but instead of the “new fangled” switching supply of the FT-One the FT-980 had a traditional analog supply and the heat sink and fan were far too small. Even in receive only mode the noisy supply fan would cut on after about 5 to 10 minutes and run continuously. I later rewired it to use an external Astron supply to supply the 12 volt (and through it 5 volt) power needs so all the internal supply had to cope with was the 24 volt finals and it did OK with that. Fast forward 10 years and I had ordered a new FT-1000MP with a full set of Inrad filters and my first major use of it was a friend and I operated in a 160 meter CW contest. I had built a homebrew triple 4CX800 amp to conservatively run the legal limit in any mode and was using a Hy Gain Hy tower modified as a full power inverted L on 160. We worked quite a few South American and Caribbean stations but several hours in nothing from Europe. I then checked my email and found several EU amateurs questioning/complaining about me not answering their calls. I went back into the shack and added the R-4C with Autek QF1A as an external receiver to the FT-1000MP and started hearing EU CW signals that were inaudible on the Yaesu. That solidified my respect for the performance of the R-4C.
