Hickory Fire!

[yardbird]

I wanted to see if you radio guru's could help me out?

I have been listening to Hickory Fire on the Viper System and it receives great.

I wanted to see if anybody had the 800 Mhz frequency they operate on for fire ground operations?

All I know is they advise switch to "Direct 6"

All the NPS 700 & 800 Mhz channels have been tried and nothing.

Just curious to listen.

Any help would be appreciated

Thanks

David

I haven't listened to Hickory FD in quite some time. When I did the Viper TGID was just a patch from the conventional freq..

I assume that Viper TGID 9555 or Hickory's trunked system bore no results for a fire ground transmission?

I would check the 800 tacs. I know that RFD uses some direct freqs that come from the 800 tacs. Wake County gave us a cheat sheet to convert RFD directs to 800 tacs on our TGs. Don't have it handy but basically like RFD Direct 4 = 8TAC94, I just made that up for an example.

Try 769.04375Mhz NAC 718 for Direct 6. I (mostly) exited the radio world on September 1st being as how I retired 5 years ago but radios didn't let me retire.

My apprentice and I programmed Direct 6 and Direct 7 into all the EMS portable radios last summer but I turned all my programming gear over to him on September 1st and I don't have the exact parameters. I can't even remember what frequency Direct 7 is.

This much I know for certain......there's no range for these simplex/digital frequencies......Hky Fire ran a call about a quarter mile from my house and operated on Direct 6 a few months ago and I could barely copy them on my formerly county issued radio.

They are used for close up interior fireground operations only.

That's a starting point Mr. Sigmon.

Does it stand to reason that all of those fire ground channels would fall in the regional low power section of the band plan? The frequency you listed is in that plan and is either on the 5 & 6 or 7 & 8 pair in the regional low power plan, base frequency (I don't recall which specifically).

If so it would stand to reason that 769.00625, 769.01875, 769.03125, 769.04375, 769.05625, 769.06875 could all be entered and assuming you were in range the fire ground channels could be sniffed out in a hurry. I think that covers all the regional low power freqs in that block.

Drafin,

Yes, that's the right idea

700Mhz F1 700Mhz F2 700Mhz F3 700Mhz F4 700Mhz F5
769.00625Mhz 769.01875Mhz 769.03125Mhz 769.04375Mhz 770.9625Mhz

These are the frequencies

Here's the NAC's

Catawba $518 $618 $718 $818 $918

Here's how they are supposed to play out

SO NAC LE NAC FIRE NAC EMS NAC PS NAC

Also, "Repeater 1" and "Repeater 2" are the 800 mhz Public Safety Interoperability Frequencies, but instead of analog they are P25 with NAC's attached.......but again, since I turned my stuff over I don't have the exact parameters. I'm supposed to be rigging up some base stations in the future, if I get a chance I'll look them up and post them.

In the meantime, life without the responsibility of radios is wonderful.
