Interesting find

[INDY72]

I did find an interesting factoid while looking at the new narrowband changes for several agencies.... They even narrowbanded their low band frequencies. Even though they no longer use the VHF Low Band interop freqs anymore, and there is no reason to narrowband low band. Apparently they just decided to upgrade all the gear to narrowband capable. Not all agencies did this, just a few. But it was just an interesting thing to find VHF Low Band with the narrowband designation. Now if I see the NexEDGE, or MotoTRBO designation on VHF Low Band, I may start questioning folk's sanity a LOT more.

Low band P25? Ought to qualify for a federal grant.

LOL now that would be interesting...... Would also be the first time Low Band range would be far less than normal. Of course that qualifies for ANY digital that would be on Low Band.... Makes me wonder if on HAM way down in the freqs, if anyone has tried like D-Star over the air long range on them. Not through an internet linkage, or node... Straight up radio to radio.

But as for the narrowbanding on low... would narrowband work on AM, aka CB, or HAM, or HF?

I have seen them add P25 emission designators to a low band license. Probably just a pencil pusher that modified every frequency on the license regardless of what band it was in.

Here is one with P25 on 37.180

There is already one digital voice modem for use on HF ham bands.
AOR ARD 9000 DIGITAL VOICE MODEM - DIGITAL SSB FOR HF!
Some of the encryption used on HF by the military, etc. is basically the same thing.

So 8K10F1E is P25? Somewhere I'd like to find a list of those designations.
