Special on IC706mkII
From: SM6WXO
I have tried some special buttons on IC706mkII:
Push TS and DISPLAY while power up and you will see a strange power on check.
Push P.AMP/ATT and RIT/SUB while power up and you will be able to see SHIFT-ADJ on your 706mkII. Dont know what this
is for, recalibrating ?
I think that these things even works on the older version of 706, dont know.

TX range expansion for IC-706MKIIG
Author: Karel OK1DNH - kebert@ext.epe.cz
TX range expansion on HF, VHF and UHF is very simple. When modified the radio will also transmit AM mode in the aircraft
band with approximately 1 watt at 118 MHz to about 17 watts am carrier at 136 MHz.
On MAIN BOARD under speaker near Xtal you can see two rows of solder dots for SMD components. Only on position 10 (from
left) is diode (D2030), which is necessary to remove.
Thats all.
After connecting power radio will be reseted and TX range is expanded.
