...no, they are independent on receive...so if you tune a signal on the r75 you must set the freq on the 718 manually..
The receiver SHOULD track the transceiver if this is set up correctly. But the transceiver shouldn't track the receiver if it's tuned independently.
its a lot like using the spot feature on the fl101 and fr101 of yesteryear...
Must have read my comments elsewhere on the site about FRs.

I bought a pair years ago, sold them...got another analog pair individually, then a couple more FR-101Ds. A YO-101 and SP-101B/PB followed. Some day I'll add an FL-2100B to that lineup. All the receivers I have are fully optioned, and I have a couple spare IF Units with different (narrower) filters that can be swapped in as warranted.
An op from Italy published a mod that adds rejection tuning to the FT-101, and this is directly applicable to the FR-101. I have all the required mechanical parts to add a concentric pot to the "Att" switch and will convert each receiver in turn. The new pot will control the notch frequency. Why Yaesu didn't implement such a feature (as they did with the FT-301) is puzzling.
