Hi David,
I can't say whether the extended transmit modification "changes to FT-857 with no D". But here is what I believe happens when the modification is made:The radio has transmit coverage which matches the receive coverage, except no transmit below 1.8 MHz; no transmit in the FM broadcast band; no transmit in the aeronautical VHF band.There are no special channel positions on the radio for the five amateur 5 MHz channels. However, with the extended transmit capability the five channels can simply be programmed into five of the 200 memory channels.Two-meter band and 440 MHz band amateur repeater offsets are no longer set automatically. However, any offset can be set before saving a repeater pair into a radio memory.All memories are erased on the radio... but with CHIRP, you can easily restore your previously programmed memory channels.For programming with CHIRP, specify FT-857/FT-897 (not FT-857D/FT-897D).The details on how to make the modification are available online -- e.g., see MARS Modification For Yaesu FT-897D. I understand that upon presentation of proof of MARS or CAP participation, Yaesu technical support will also provide the modification instructions.

Is this one of the changes that happens when you open up the FT-857D?  I never did that mod because I thought it would no longer work correctly on 5 MHz amateur shared band.
It changes to FT-857 with no D?
