Default CM Ham frequency

Nathaniel:

Attached is last year's trail list with Ham frequency and CB channel. Per our discussion at the meeting last week, I need to know what changes we need to make for this year. I tried to email to you, but it failed and couldn't figure how to attach a file to a PM, so I decided to use the HAM forum.

I have the Utah frequencies in a worksheet at home. I can post them up tomorrow, if you can wait (I'm out of town right now, flying back in the morning).

Thanks, Mary. I will get to it today.

Thanks, Hants. I just need to get the trail frequencies designated so that each trail has a freq, and those sharing freq's are far enough apart to not give intermod.

Check the actual Utah bandplan. They not simply 20Hhz separation -- they delete some frequencies & coordinate others.

That's true, Hants. Utah does use a 20KHz channel spacing, which is different than Colorado where we use 15KHz. I'd forgotten about that.

Checking the UVHFS bandplan, looks like 145.510 - 145.790 (odd 20KHz), 146.420 - 146.600 (even) and 147.400 - 147.600 (even) are FM simplex ranges. That gives them something like 36 simplex channels on 20KHz spacing. Simplex ranges are not coordinated, although some do get used by ARES, ERC and other groups. But they do not have exclusive use of the frequency.


144.000-144.100: CW - No voice modes allowed per FCC §97.305
144.000-144.050: CW EME (e.g. "moonbounce")
144.050-144.100: CW/Weak signal
144.100-144.300: Phone (SSB), etc. (no FM voice)

144.100-144.200: SSB (Weak Signal and EME)
144.200: SSB/CW weak signal calling frequency
144.200-144.275: General SSB operation
144.275-144.300: Propagation Beacons

144.300-144.500: Proposed OSCAR (Satellite and Spacecraft) subband (new) - Please avoid other types of operation.
144.390: Nationwide APRS (Automatic Position Reporting System) Packet chanel.
144.500-144.900: 2 Meter FM repeater inputs (odd-numbered 20 KHz channels beginning at 144.510 MHz)
144.900-145.200: Simplex/Duplex Packet operation
145.200-145.500: 2 Meter FM Repeater outputs (odd-numbered 20 KHz channels beginning with 145.210 MHz)

145.500-145.800: Simplex, miscellaneous/experimental (no repeater operation allowed per FCC part 97.205) using various modes (odd-numbered 20 KHz channels beginning with 145.510)
145.800-146.000: OSCAR (Satellite and Spacecraft) subband - Please avoid other types of operation.
146.000-146.400: 2 Meter FM repeater inputs (even-numbered 20 KHz channels beginning at 146.020 MHz)
146.420-146.600: 2 Meter FM simplex operation (even-numbered 20 KHz channels beginning at 146.420 MHz)
146.600-147.400: 2 Meter FM repeater outputs (even-numbered 20 KHz channels beginning at 146.620 MHz)

147.400-147.600: 2 Meter FM simplex operation (even-numbered 20 KHz channels beginning at 147.400 MHz)
147.600-148.000: 2 Meter FM repeater inputs (even-numbered 20 KHz channels from 147.620 MHz to 147.980 MHz)

Notes:
* For repeaters with outputs on 147.000 MHz and below, Utah uses a Negative 600 KHz split.
* Those repeaters with output above 147.000 MHz use a Positive 600 KHz split.
