FM is not AM/SSB
Remember, these are suggestions for FM operation on 2 meters in Wyoming. There are different bandplans and spacings used for AM/SSB. Also, the Considerate Operators Guide is good to keep in mind.
Frequency Coordinator
Each state's Frequency Coordinator is tasked with publishing and establishing the common FM simplex channel spacings for their state. However, due to a persistent and apparently absolute silence from the WY Frequency Coordinator on the subject (or, any other subject), we developed our own suggestion and offer the following table of 2m Simplex frequencies for routine use.
NOTE: The WY coordination group has published a Wyoming plan Find it here. It covers 2m, 6m and 70cm This IS the authoritative plan for Wyoming and supersedes all others.
Channel Spacing
The following table shows the best information we have as to what our neighbouring states are using for channel spacing.
Wyoming uses the 15Khz channel spacing scheme.
| 15kHz | 20kHz |
|---|---|
| Wyoming | |
| S. Dakota | Montana |
| Nebraska | Idaho |
| Colorado | Utah |
WY 2m Simplex
This is not LAW! This is merely a suggested guide for the convenience of the community. As long as any operator is following Part 97, they're allowed to do what they choose.
| 146 | 147 |
|---|---|
| 146.400 | 147.420 |
| 146.415 | 147.435 |
| 146.430 | 147.450 |
| 146.445 | 147.465 |
| 146.460 | 147.480 |
| 146.475 | 147.495 |
| 146.490 | 147.510 |
| 146.505 | 147.525 |
| 146.520 | 147.540 |
| 146.535 | 147.550 |
| 146.550 | 147.570 |
| 146.565 | 147.585 |
| 146.580 |
2m FM Calling
And, as is the case in the rest of North America, the 2m FM calling frequency is 146.520Mhz.
Once you've made contact and established a QSO, it's considered 'best practice' to move your QSO to another, agreed frequency. However, due to the lack of use, many choose to remain on 146.520 for the duration of their QSO.
