BTW, Dave Martin K6KOW and the former editor of Kitplanes Magazine and I did
the "Aircraft Mobile" chapter of the ARRL publication on mobile operation.
You may want to get ahold of a copy of that ARRL book.

Thanks for the tip; I just ordered a copy.

I think I can get AC 20-98 online from the FAA, as well, but their server
appears to be having problems.

AC 20-98 has been canceled by the FAA, but AC 20-67B is pertinent. Here ya
go:

--------------
AC 20-67B - AIRBORNE VHF COMMUNICATIONS EQUIPMENT INSTALLATIONS

Department of Transportation
Federal Aviation Administration

1/16/86

Initiated by: AWS-120

1. PURPOSE. This advisory circular (AC) sets forth one means, but not the
only means, of demonstrating compliance with the airworthiness rules
governing the functioning of airborne VHF communications equipment.

2. CANCELLATION. AC 20-67A, Airborne VHF communication System Installations,
dated October 17, 1972, is canceled.

3. RELATED FEDERAL AVIATION REGULATION (FAR) SECTIONS. FAR Sections .1301 of
FAR Parts 23, 25, 27, and 29 {23.1301, 25.1301, 27.1301, 29.1301};
25.1307(d), 29.1307(e); and .1309 of FAR Parts 25 and 29 {25.1309 and
29.1309}.

4. BACKGROUND. Airborne VHF communications systems and equipment have become
more complex over the last several years, using digital data applications
and computerized equipment and control. There has also been an increase in
the use of select calling and digital data link applications, in addition to
mandatory air traffic control air to ground voice communication. To meet
these developments, the Radio Technical Commission for Aeronautics (RTCA)
SC-148 committee has presented recommendations to cover performance and
compatibility for the wider variety of VHF communications equipment being
installed. Existing technical standard order design standards for VHF
communications equipment and for substitute equipment (PC 20-41A, Substitute
Technical Standard Order Aircraft Equipment) are still applicable for
specific systems and should be referred to for guidance.

5. ACCEPTABLE MEANS OF COMPLIANCE. An acceptable means of compliance with
the regulations referenced in paragraph 3, as they apply to the functioning
of airborne VHF communications equipment provided for use under IFR
conditions, is to satisfy the criteria set forth in Section 3 of RTCA
Document DO-186, "Minimum Operational Performance Standards for Airborne
Radio Communications Equipment Operating Within the Radio Frequency Range
117.975 to 137.000 MHz," dated January 20, 1984. This document may be
examined at any Federal Aviation Administration regional office or purchased
from: RTCA Secretariat, One McPherson Square, 1425 K Street, NW., Suite 500,
Washington, DC 20005.

I miswrote. I don't know for certain that AC 20-98 has been canceled, but I
think it has. I just don't have it. If anyone finds a copy, please let me
know.

I've got the damned thing, but it is just getting the time to scan it,
change the index page, and put it up.

If you will send it to me I will be happy to scan it and post it.

Yeah, like copying it, putting it in an envelope, running it down to the
post office is going to save me time.

I've offered to do put ALL my articles up if somebody will take the time to
take the raw files, make the graphics files, the index page, and post them.
As yet, no takers.

I'm not going to do it piecemeal.

AC 20-98 has been canceled by the FAA,

20-98 has not been cancelled, but it is not available in the current
downloadable list or anywhere else. For an AC to be CANCELLED, it has to be
done specifically. THere is a great difference between being obsolete and
being cancelled. And, until the FAA cancels it or comes out with an updated
edition, it is "the last available information" on the subject.

but AC 20-67B is pertinent.

I do not believe that it is pertinent. All of the references and
documentation point to AIRCRAFT VHF COM, and not VHF Com in general. I do
not believe that it covers amateur or other types of communications
equipment.
