==modification==[http://www.uksmg.org/content/ft847.htm The Frequency coverage] of the 847 TX once modified is:1.8Mhz to 76Mhz ( no gaps ) DO NOT TRANSMIT IN THE RANGE 32MHZ TO 37MHZ AS YOU ARE TRANSMITTING INTO A LOW PASS FILTER AND COULD DO DAMAGE TO THE POWER AMPLIFIER.137Mhz to 174 Mhz and 410Mhz to 470MhzThe modifications are quiet simple:Remove bottom cover you will see the backup battery, on the left hand side their are 6 solder pads numbered 1 to 6 pad one already has a 0 ohm chip resistor across it, short pads 2 and 3 with 0 ohm chip resistors or just use solder ( not as neat ).Check pad 6 if it has a chip resistor on it remove it ( if it is not removed the radio will not go out of band on HF and 6M )Replace cover , reconnect radio press the fast and lock buttons together at the same time and turn the radio on this will reset the micro ( you will loose all your memories ).Testing this mod on a dummy load and watt meter found 1.8Mhz to 30Mhz getting a good 100W right though, from 37Mhz to 50Mhz was also very close to a 100W!!From 54Mhz to 76Mhz the power did drop off the higher the frequency at 70Mhz getting approx 20W.137Mhz to 174Mhz was pretty good with output of 50W!! found the same on 410Mhz to 470Mhz !!
