Today I made the 60 Meter/MARS transmit mod. on my FT-1000 MP Mark V Field, posted on http://www.mods.dk/view.php?ArticleId=2605 by W6AAV. The mod. requires good eyes and a steady hand but I have neither, so I used a fixed magnifying glass, tweezers, a jewelers screwdriver, desoldering wick braid and a 15 watt soldering iron to desolder and resolder the chip resistor.

I had already gone into the 9-9 menu when I first bought the rig months ago and changed it to "GEN", not realizing at the time that the 60 meter/MARS mod. on the Mark V Field was more complicated then the Mark V. I left it on "GEN" even though it didn't work. In any event today I did not have to do the master reset of CPU as described on the mods.dk site by W6AAV, repeated below:

4. Reset the CPU by holding down the "SUB" + "29" + "ENT" buttons while you power on the radio.

All I did was close up the rig and fired it up and now have all band transmit with 200 watts from 1500 kc to 30000 kc and did not lose my customized menu settings or my auto tuner memories or 100 frequency memories. Yeah 200 watts as I made the power increase mod. too recently but only run the rig at 125 watts, as I found that my Field only transmitted with 90 watts out of the box on 160 meters.
