Hello Jim, well I have both the R7A & the TR7A mated together and I see very little if any difference in the receiving capability of either unit. The R7 is basically the same as the receive section of a fully loaded TR7, but with a few minor exceptions like the notch filter and noise blanker upgrade. The ability to switch between receivers is nice if you need that but for a typical QSO having the twins is no real advantage. I do notice with my setup if you don't have all three oscillators set perfectly in both units, in transceiver there could be an offset in frequency between receive and transmit. Both units interconnect the VFO and 40Mhz master oscillator signals to sync together but there are two more crystal oscillators in each unit that could be off a little to cause the offset.
Overall, having both pieces is nice to have if you want the entire station but no real noticeable difference in the basic receiving capability of either unit.

I know the R7 isn't *exactly* the same as the TR7 RX, and there is some loss through the R7 antenna splitter. I would just like to hear some opinions on how they differ in real world performance when connected together. (Yes, I cut the jumper in the TR7...). Is there anyone out there?
