Since this is basically a question for 2M AM operation in the South East, I
would first recommend looking at the current 2 meter band plan as established
by the South Eastern Repeater Association (SERA) and recommended reference
material by anyone in the SE when scoping out band usage guidelines. This is
the reference >
http://www.sera.org/2.html
You will notice that the segment of 144.300 - 144.500 is labeled as
"Multi-mode" which would cover AM operation and stay away from the recognized
beacon bands. At one time, part of this segment was a AMSAT downlink band for
some of the early OSCARs but to my knowledge, there is no active birds
operating in that segment now, with the exception of 1 frequency still being
used as a ARISS uplink. Check here for the latest >
http://www.amsat.org/amsat-new/satellites/frequencies.php
But, remember that 144.39 MHz is the national APRS packet frequency.
I am aware of at least a couple of states still holding 2 meter AM nets and rag
chews on 144.450 MHz. Given that none of the above references show any conflict
with that frequency, I would recommend monitoring the frequency around the
Atlanta area for awhile to see if there are any other users, other modes, etc.
If you don't hear anything, try some QSO's there to see how it works for you.
If anyone copied here knows of a potential problem around Atlanta by using the
144.450 MHz frequency, please chime in.

Hi John,
I do not know the answer, but would be interested in it, so I have forwarded
your email question out to some of the local and national groups that are VHF
in nature.
I have some 2 meter tube AM gear also, including a CD Gonset rig with matching
amp. I will be interested in QSOs with you.
I will forward you the answers as I get them,
Bob

Folks,
I am interested in putting some of my restored 2 meter AM gear back on the air.
Most of it is crystal controlled and so picking the right frequency is
important. Unfortunately while on 6 the amateur radio community has settled on
50.4MHz for AM work no such consensus seems to exist for 2 meters. I can find
no published standard for GA or the Southeast. According to "The AM Window" (
www.amwindow. org/freg. htm ) NYC-Long Island uses 144.28 MHz and LA uses
144.265 Mhz. The problem I see with 144.28 MHz is the presence of beacons in
CO, VA, QC, ON, NB, TN and TX on the same frequency. The frequency used in LA
is on the high end of the general SSB assignment (144.200 MHz to 144.275 MHz)
and seems a good possibility.
So my question, especially to those of you who operate 2 meter SSB is would AM
operations in North GA on 144.265 MHz cause inordinate problems? If so, is
there another 2 meter AM frequency already in use in GA/North GA and if so,
what is it? Or is there another frequency that you can suggest?
Two meters has always been a popular band. Before FM and SSB came along, it was
the place many of us got started on AM phone. There is lots of vintage 2 meter
AM gear out there. It would be fun to get some of it back on the air.
Please advise,
John, K7SYS
