[VHFcontesting] [VHF] FM Contest Frequencies

Hi Les,

You have 2 good ideas for 2 meter FM. KISS, and I'd go one step further and 
recommend only one frequency---146.580 as the main go-to FM frequency during 
the contest. That would fit with the rules and as Chris mentioned, the 
regions that use either 15 or 20 KHz recommended spacing. Then, if they 
found .58 busy they could QSY to another local simplex frequency. Of course 
anyone can use any recognized simplex frequency, local option or national. 
But FM use in the contest is way down now, and newcomers looking for a place 
to find a contact might do well monitoring .58 during the contest. We want 
them to get interested in VHF contesting and they need to get some contacts 
in order to get interested. There would be no reason to change rules 
(ex:1.9) as promotion of 146.580 fits within the existing rules. And the 
idea to scan 2 meter simplex segments at 5Khz is a valid one also.

I'm not trying to make any rule change. Rule 1.9 currently lists ten or
more suggested simplex channels, and was drafted well before the
creation of the new "FM Only" category.

I'm simply trying to consolidate that list into two "calling channels",
with the hope that at least one of them will work nationwide. This
allows the activity to be concentrated, increases the odds of successful
contacts, and increases the fun for everyone.

Can you imagine being a newcomer to VHF Contesting? You hear something
on the local net, or club newsletter about the new "FM Only" category,
and then you spend all day calling without an answer on ten different
channels? Frustrating and not likely to be something you repeat.

In some areas (like Alabama) simplex activity is almost entirely on
146.520. I think it's far better to promote two frequencies, than an
entire group. K-I-S-S should be the rule when trying to attract newcomers.

Also, I've routinely made early morning contacts on simplex on .52 out
to 200+ miles. The "local" simplex frequencies that are popular can vary
quite a bit even in that distance. I think having nationwide watering
holes makes more sense than simply "scanning" ten + channels.

I've got to program my FM rig to scan the simplex channels on a
time-based basis (rather than looking for a broken squelch) as I expect
many signals to be too weak to break squelch.

I'm going to encourage local ARES and CERT groups to mobilize their
membership and use this as an opportunity to test out their simplex
