[ICOM] Icom 706 MKIIG cap/mars mod

[David Nagel]

Dick;

Most amateur radios do not meet some of the more esoteric specifications found in the NTIA Red Book. (If you suffer from insomnia I recomend the Red Book.)
One of the Civil Air Patrol work groups has review the specifications of virtually all the available transceivers and compiled a list of those that meet the specs. Many radios fail only on spurious emissions limitations. The only specifically approved HF amateur radio is the Yeasu FT-817/ND. Then only at the 5 watt output level, which is the maximum these radios put out. The Icom IC-706mkIIG will meet the specs if the output power is limited to 5 watts also.
Go to http://ntc.cap.af.mil/ for a complete list of HF and VHF radios. 
It should be noted that this file is used by many US Government agencies to justify their radios. However, as may be surmised, most radios are commercial types with their associated costs.

National Telecommunications and Information Administration (NTIA) is the 
President's principal adviser on telecommunications and information policy 
and in recent years has specified the technical requirements for CAP and 
MARS transmitters.  To operate on CAP and MARS frequencies, the transmitter 
must meet these requirements.

I believe some of the newer amateur transmitters meet NTIA specs, but my 
understanding is that most do not.  I am sure others on the list can 
clarify this latter point.
