[ICOM] Icom 706 MKIIG cap/mars mod

[David Nagel]

Jim;

The power limit is to the transmission line feeding the antenna. Therefore an external power amp will take the radio out of compliance. Believe me we have looked at all the options.
Sixty meters is an amateur radio band. Any governmental radio operations must follow the NTIA requirements. Once again, believe me we have looked all the options.
NTIA does not affect any FCC controlled operations and is completely separate.

be possible to run the 706mkIIG at 5 watts into an Ameritron ALS-500
amplifier for instance to bring the power back up some?

2.  It is my understanding that 60 meters does NOT require any NTIA
certification and that "opened up" radios CAN be used (within the allowable
power limits) on 60 meters.

Tnx es 73, de Jim KG0KP

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.
