[Icom] Mods for ICOM 756 PROII

Tue, 21 Jan 2003 16:44:37 -0800

Hi Bruce,

On checking with the appropriate authorities, I found that the IC-756Pro/Pro
II are NTIA-compliant.

Here is the list of compliant HF equipment:

I would have expected the IC-781 to be compliant, as it meets NATO
requirements (as far as I am aware).

Adam and all,
Please check prior to doing any MARS/CAP/FEMA type mods for NTIA
compliance.
I just received the latest list of compliant rigs for VHF/UHF as tested
and OK'd by the higher ups and unfortunately almost none of the Icoms
and Yaesu rigs make the grade.

As far as HF is concerned, the 756 might be OK, but you need to check.
All I looked up was my 781 and 751A.  The 781 is good to go, the 751A is
not.

This is the newer requirement, not the stuff as of last year or so.
They do know too if you are not compliant.  I had a FEMA control op chew
me out for not being on the mark when in QSO with him at around 11 mhz,
or so, on the 751A.
The 781 has been just perfect.  But you do need to check!

73, Bruce K1XR

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.

Best 73,
