In case anyone was wondering, here are the coordinated band plans for Colorado on 2m, 1.25m and 70cm.

As a major aside...

Does anyone know was some of the terminology means?

16K0F3E
SNP - Shared No Protection pair
E&SE - Emergency & Special Events

So OK, SNP and E&SE sorta make sense, right? At least in that they are words you can figure out meaning for. The other one, though, 16K0F3E. That one is an odd one, eh? That designates the type of emission modulation you are expected to do. If you look in your radio manuals you will see similar designations. Anyone wonder what it means?

16k0f3e is an analog modulation standard governed by:

TIA/EIA 603-C--- Land Mobile FM or PM Communications Equipment Measurement and Performance Standards


Which as far as I can tell is related to emissions standards maybe originally set forth by NIST and adopted for use by the FCC? My look-up skilz might be bad.

Yeah, you are on the right track, the emissions types are ITU designations, adopted by the FCC.

OK, you break down modulation types by parts, so 16K0F3E.

16K0 designates bandwidth, literally read. So 16K0 means 16.0KHz bandwidth.
F is modulation type, in this case FM
3 is signal type, here 3 means single channel analog
E is expect type of information and E means voice.

There are many types and this does not just cover ham radio. For example, 20KOW7W is 20.0KHz bandwidth (20K0), Special Case (W), TDMA (7), Multiple mode (W, i.e. data and voice). That defines the emissions type for Motorola iDEN cell phones like Nextel used. They say special case because iDEN uses multiple modulation modes for data and voice, I think M16QAM and QPSK, rather than just one like our radios.

How about 10K0A3E? That is 10K0, A, 3, E, so 10.0K bandwidth, A = double side band, full carrier AM, 3 = one channel analog and E = Voice. Can you guess what that is? That's regular AM broadcast radio.

How about soon-to-be ancient TV. With unknown bandwidth, you can say that the type would be C3FN, where 'C' is vestigial sideband (ever heard of NTSC), '3' is single channel analog, color ('N') video ('F').

My FT-8800 says it can do F3 and F2 emissions. The F means it can do FM as the only modulation type and the 2 and 3 designate it can do voice (the 3) and non-voice (the 2). Non-voice in this case means it is capable of transmitting something besides voice, so digital modes. That might be TTY, PSK31, APRS, etc. So if it was doing full channel bandwidth APRS, I would be doing 16K0F2D, 16.0KHz, FM, non-voice data. In this case non-voice means digital, but the channel is not technically digital because you might also do Morse Code for example.

:confused:



I think I need a class in just how to use my radio. I'm lost.
I do have some beer though Dave... Just sayin'... hint...

The big round thingy changes where yer talkin.

The little round thingy changes how much yellin you have to do to talk over the radio thingamagig.

Other than that, I dunno, there's a lot of switches n' buttins n' stuff.:hill:

Is the Band Plan sheet something good to keep in a cruiser to be able to call out and reach someone? How about a Utah band plan?

Please note that the highlighted sections are for FM repeater and/or simplex operation. Also note that Utah is among a handfull of states that do not go by the 15kHz separation, they use 20kHz.

Utah 2 Meter Bandplan:

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.
