Working Group
for
Frequency Coordination
Purpose of this Working Group:
The purpose of the Frequency Coordination Work Group is to discuss, develop, and .............used within the Michigan Packet Radio networks.
Objectives of this Working Group:
The primary objectives of the Frequency Coordination Work Group is to ...............
Members of this Working Group:
Jay Nugent WB8TKL jjn@nuge.com (734)484-5105
Jon Harris KC8VAB jonharris2@comcast.net
Next meeting of this Working Group:
- no date or location has been set -
- discussions will be conducted on the DRG mailing list -
Since the Michigan Area Repeater Council (MARC) does not coordinate frequencies for use by Packet Radio Nodes, BBS's and Network Backbones, it has been suggested that the DRG take on that task.
At this point in time these are the ONLY frequencies recognized and protected by the MARC:
From the MARC website:
======================
For packet operations, the following channels will be protected from coordinated operations.
2 meters
========
144.910, 144.930, 144.950, 144.970, 144.990
145.010, 145.030, 145.050, 145.070, 145.090
145.510, 145.530, 145.570, 145.590
145.610, 145.630, 145.650, 145.670
145.710, 145.730, 145.750, 145.770
147.540, 147.560, 147.580
(Note that 145.76 is *NOT* protected and also lays outside the RACES sub-band)
1.25 meters
===========
222.340 - 222.360 / 223.940 - 223.960 Repeater input/output
223.520, 223.540, 223.560, 223.580, 223.600
(Note that 223.4 and 223.44 are *NOT* protected)
70 centimeters
==============
-no frequencies are noted for Packet use-
(Note that the GL-Net 9600 baud backbone frequency of 445.6MHz is within the "Voice links" sub-band)
Band Plans for "Digital Communications"
---------------------------------------
904.00 - 906.00
916.00 - 918.00
1248 - 1252
1258 - 1260
1297 - 1300

MIPAC RESOLUTIONS
as of April 8, 1995
X-1. It was agreed for MIPAC and state users to start looking at using
145.510 - 145.690, as available per local conditions. Please note
that 145.550 is more or less a permament "space frequency", and
that 145.530 is in use in SWMI and Northern Indiana for bbs to bbs
forwarding.
X-2. It was recommended that where ever possible, 147.560 will be used
state wide primarily for TCP/IP use. Within the SEMI area 147.56
is designated as TCP/IP only, 9k6, and low level lan operations.
(Revised at 8 april 95 meeting)
X-3. That each bbs sysop within Michigan hold for review all bulletins
entered by local users till that sysop, or remote sysops review
said bulletins for proper content. In addition, all Michigan bbs
sysops will allow bulletins from other Michigan bbs's to be
forwarded automatically. This will put the burden of trust amongst
the sysops. Also, MIPAC sysops will pass around to other out of state
bbs's what we are doing here in Michigan to handle this situation.
(Reviewed at 14 Jan 95 meeting)
X-4. A resolution to support the following additional 2 meter frequencies
for digital use in Michigan.
145.510 145.530 145.570 145.590 145.610 145.650 145.670
145.710 145.730 145.750 145.770
Of these frequencies 145.530, 145.630, and 145.730 were set aside
along with the existing 145.030 for use as keyboard to keyboard,
chat and\or converse activities. A request made to the SEMI Regional
Coordinator to use 144.930 for the same activities in the SEMI
region only was approved.
X-5. MIPAC will join other amateur groups in asking hams to keep clear of
145.550 and 145.695 to help the Space Station and for use as a
national A.R.E.S. frequency.
(Refer to MARC Resolution #1 dtd 12 Sep 92)
X-6 The Digital Freqs for the 902mhz and 1.2ghz bands from ARRL REPEATER
DIRECTORY 94/95 Edition are adopted for use in the Michigan
bandplan. Following is that portion of the Directory with the
typos corrected:
Pg.41
903.000mhz - 906.000mhz Digital
915.000mhz - 918.000mhz Digital
Two 1.5Mbit/s links. They are 903 - 906mhz, and 915 - 918mhz
with 10.7 mhz spacing.
**********************************************************
Pg.45
1246.000mhz - 1248.000mhz Narrow-bandwidth FM point-to-
point links and digital, duplex
with 1258 - 1260.
1248.000mhz - 1252.000mhz Digital Communications
1258.000mhz - 1260.000mhz Narrow-bandwidth FM point-to-
point links and digital, duplex
width 1246 - 1248.
1297.000mhz - 1300.000mhz Digital Communications
1.) 2 mhz bandwidth channels at:
1249.00 1251.00 1298.00
2.) 100 khz bandwidth channels at:
1299.00 1299.45 1299.75
1299.15 1299.55 1299.85
1299.25 1299.65 1299.95
1299.35
3.) 26 khz bandwidth channels at:
1294.025 1294.125
1294.050 1294.150
1294.075 1294.175
1294.100 National packet simplex calling
(Revised 8 April 9)
X-7 That the following frequencies be used for TCP/IP only:
441.025 mhz 9k6
223.540 mhz 9k6 @ a later date
223.580 mhz 9k6 @ a later date
This pertains to SEMI area; and to be expanded to other areas as
the need increases with the hope of full state participation in
the near future.
(Adopted 8 April 95)
