FL-101/FR-101D. All band segment crystals populated including WARC and the SWBC segments. FM board and both VHF converters installed, as were all RX filters.

FT-201/FR-101D. Ditto the above.

The only things in the 101 line I didn't own were the FL-2100B and an FT-101/FV-101/FTV combo. My main gripe with the twins was the hokey way Yaesu chose to implement transceiving. They allowed each radio's HFO to run independently when in transceive mode, rather than using the TX or RX HFO to control both pieces (Drake did this with the 7 line and Kenwood's 599/820 series utilized the same scheme.) If the HFO crystals varied significantly in frequency between the transmitter and receiver it was very hard to net them - and on some bands it was simply impossible. You had to run the setup in "independent" mode.

No notch filter was another biggie. I can live without a PBT most of the time if the RX filter skirts are sufficiently steep but a notch is almost a must-have.
