[Icom] Mods for ICOM 756 PROII

[Adam Farson]

Hi Ken,

As other reflector members have mentioned, the only mod of which we are
aware is the general-coverage transmit mod. As all the functionality of the
radio is hard-coded in CPU and DSP firmware, there are no other mods in the
conventional sense. And Icom are not about to release their source code!

Please refer to http://www.mods.dk/ for the general-coverage TX mods. They
involve SMT desoldering and soldering. There is no need to do these mods
unless you require the ability to transmit outside the amateur bands (as do
operators in MARS, the US Military Affiliate Radio System, or CFARS, the
Canadian equivalent).

As my friend Bill K3YC pointed out, the -6dB point of the  2 ~ 6 MHz
transmitter LPF (following the PA) falls in the 5.9 MHz region. As a result,
the output will fall to 25W at 5.9 ~ 5.999 MHz. At 6 MHz, when the 6 ~ 8 MHz
LPF is selected, the radio will again deliver full output.
