You make that look very easy! The contacts are tiny, I did my 'D' model mainly with a silver conductive pen, as my solder skills were not as good a yours. I managed to remove some of the contacts with a fine tipped iron as required, but used the pen for the rest. Been working fine for quite a few years now.
I had the MARS mod done on one of my 857Ds. It messed up the automatic frequency shift for repeaters. The mod allowed me to transmit on 11m but since the radio isn't FCC certified it was legal unless under emergency situation. No longer interested in MARS I went back to original configuration. After I joined a volunteer fire department I kind of wished I left it alone. However, transmitting on FD frequencies on a non type accepted radio also puts a frown on the FCC's faces. Now the department uses UHF digital radios that are P25 so it doesn't matter anymore.
I did the Softmod on mine from 2003 . Someone hacked it to bits trying to do it with I assume a welding iron. I have 2 Japan models that the softmod opens up the RX but not the TX....The Japan models are only really good for HF since the VHF and UHF are different (minus 60M)

The result gives the month in which the radio was manufactured. Note that the letters will range from C (January) through N (December). Thus, my FT-817 radio with a serial number of 9J271567 would have been manufactured in 2009 (9), during the month of August (J, August is the 8th month), was part of lot 27, and was the 1567th radio in that lot.

This was a huge help. Thanks for your work.
Always impressed with your knowledge!

Can you transmit on GMRS with it?
