    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

WMNF Ops

Laconia is the Hq but really isn't near the forest itself. There are some ranger offices scattered throughout.

The PL tones listed are used to access the various repeaters. All units monitor open squelch (CSQ). Some repeaters carry the PL and some don't so the best bet is to listen to it w/out PL.

There has been mention of 168.050 being used for "Fire Tactical" ops but I've never heard it (nor are there many forest fires there). That is coincidentally NIFC "Tac-1".

Hello:
I don't mean to bum posts here, but could someone explain why each of these mountains have frequencies? Do they have repeaters and rangers on each mountain with different radio channels?

Thanks,
Eric

Eric - let me try to explain. WMNF is a very mountainous area. One repeater site cannot adeequately cover all areas, therefore multiple repeater sites are needed. All of the repeaters use a common input freq and a common output freq. In order to prevent multiple repeaters from activating at the same time, different PLs are used on the inputs of the various repeaters.

You have to be familiar with "repeaters" and with "PLs / CTCSS" in order to get a good handle of the WMNF radio system.

I have the URL for the WMNF Radio Operators Guide. Let me dig it up. here ya go - https://sites.google.com/site/usfsradiofreqs/home/new-hampshire-freqs
