Justin et all,
The Mark V Field power modification is simple but it will attract naysayers
that will warn of power supply damage/failure, finals failure, degraded
transmitted spectral purity, etc.
Pop the top and bottom covers. Gently turn the rig upside down on a hard
surface with the front of the rig facing you. There are three boards visible.
One is the "Control" board on the left side, the "AF" board on the back right
side and the "IF/Filter" board on the front right side. Go to VR3003 on the AF
board and turn it clockwise. It's marked "RF Power" (I think it was). Fully
clockwise gives you 190 watts in the CW mode on 14200 kc, 200 watts on 1845 kc
and 180 watts on 28400 kc. Of course connect an antenna with low VSWR or a good
dummy load.
I've tested the rig extensively at 175 watts on CW and RTTY and have suffered
no component failures, overheating, etc. and no transmit spectral degradation.
Of course like all mods. make it at your own risk.

Subject: Re: [FT-1000MP] Mark V Field 60 Meter/MARS Mod
Tom,
Thanks for your insight into performing this modification...I will be doing
it shortly. However, you piqued my curiosity at the mention of a 200W
modification for the Field. No amount of searching thus far yields any
information on this. Will you please provide details, or at least a link?
Also, do you really get 200W out? Need a beefier ps?
Cheers,

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.
73,
Thomas
