But it appears VHF LO-Band still has some gasp of life, at least around Lexington and possibly towards Rockwell & Richfield.
Hearing a little traffic on 43.000 MHZ FM.

I still get a fair amount on VHF Lo from here in Forsyth County. I let my radio run for several hours not too long ago and these was my findings just in case anyone might be interested:

37.040 127.3 PL Smyth County, VA sheriff
37.320 85.4 PL Grayson County, VA sheriff
39.300 632 DCS Pulaski County, VA sheriff
39.960 192.8 PL Stokes County, NC school buses
46.450 - Rockingham County, NC fire
46.970 ? Unknown data
47.100 107.2 PL NCDOT Division 11 operations
49.480 67.0 PL Stokes County, NC Pike Electric - Mt. Airy


Also, I still hear a fair amount of NCDOT on VHF lo, especially during winter weather. Some of the flagmen still use lo band HTs, although now I am seeing more of them using FRS HTs instead.

I'm not familiar with 43.000 MHz, but maybe something to do with this perhaps? ULS License - Industrial/Business Pool, Conventional License - KUN809 - FONVILLE, GRADY L

I can confirm there was heavy encrypted traffic on 43.00 today and a little bit in the clear with a 151.4 tone. Monitored while heading down I-85 to Charlotte.

i logged on for only one reason.....Taking Care of Biznesss, It's Alright! Taking Care of Bizness on Military Time ! Freak out!

ya'll would love my singing voice. anyhoo 43.000 for first time today, in the clear comms AND the sound that ya'll call encryption, which is as good an answer as any. 43.15 too I believe but need to confirm. keep dem reports coming in guys. gotta run

Didn't log anything on either of the above frequencies today in Concord or on the way back North. Guess they finished whatever they were doing. 43.00 has been active around Southside VA a lot but I haven't heard it that far south before.

not rx'd anything off of 43.0 since, anyone else?

to those who are familiar with the encryption type signal, if you rx anything on 32.55, i'd like your judgement on if it sounds like the same thing to you heard on 43.0.

I have not heard anything on 32.55 but there was some traffic around Martinsville, VA last night on 43.05. Sounded like the same thing that was on 43.00 but I don't have any recordings to compare it to.

Also I should note that when I was hearing 43.00 in Concord on Friday I was also getting encrypted traffic on 164.550 NAC 1, 165.375 NAC 1, 164.650 NAC 1, and 410.800 NAC 201. Not sure if related or not. I don't make it a habit of scanning around low band to know what is and is not normal, but when 43.05 was active last night none of the above frequencies were active. Have not been able to decode a NAC on the low band.

I tend to think it was just coincidence as those fed freqs are fairly common in use
in the area, tho i could be wrong. i do make a habit of scanning low band
and thats why the 43.000 et al. gets my attention. cause its not normal.

last year when 43.0 and 43.04 were first reported i put them into heavy
rotation with a number of scanners most of the time running off outdoor/car
roof antennas and never got a peep. was starting to wonder if my gear was
busted. then with generally the same set-ups last thurs, got multiple
hits, some prob at same time as the original reporters, so that is
interesting. the little voice comms i got gave the impression of being a
fixed base station.

thanks for mentioning 43.05. gotta wonder what the situation is regarding step spacing, bandwidth and possible bleed over. i have seen it both ways so i dunno.

keep an eye out for any NAC, tho i am not optimistic. early 2018 i
purchased a 436HP for the sole reason of trying to see if it would catch a
NAC on low-band for what now appears to be the same type of transmissions
that we are hearing on the 43's, just on other frequencies (32.55, 38.3,
38.55 and a host of others). I had been monitoring the "mystery signals"
for some time with a PRO668 but was afraid maybe it just couldn't decode,
or wasn't designed to decode NAC's on low band.

i feel better knowing that NAC's on a low band freqs can be decoded by a 436HP (as others had noted, hence my purchase), but those occasions, based on the NAC and content....were VIPER transmissions :) didn't realize i was that close to a tower at the time.

anyhoo, so far the only ones i have recv'd have been 43.0, 32.55 and possibly 43.15 on the same day as the 43.0. so far voice comms only on 43.0. will report anything new and thanks for doing the same.

Just pray the use something of a NAC greater than 000
where as Uniden drops the leading Zeros so it shows as P25 but no NAC

Got one ICE Net here in New England with $000 as the NAC

man you have got to be kidding me....... i have seen places where people were saying stuff like $67 or NAC 1 or whatever but i though they were being lazy.... out in the sticks where i live basically everything i have seen starts with something other than a 0. why in the world would uniden design it that way?????

that would be just my luck.

i know some marine systems are 00A....that doesn't bode well

between noon and now

36.7 151.4 A2A helo voice comms. in central nc talking bout concord stanly and g-boro

the most interesting though

44.8 151.4 "Flight Check 27, four four point eight fox mike radio check" generally semi-exact wording

of note a previously NOTAM'd freq for a TEMPO TOWER a KHRJ of 119.65 chirped in this afternoon with a "...eck two seven" KHRJ has a NOTAM up currently for a TEMPO TOWER tho on 122.7 so i dunno.

123.475 has had the airborne photographers/surveyors today as has been the case for a while but also a RAVENxx doing some sort of drops prob over near bragg. yesterday on adsbexchange saw a RAVENxx in same area which was a CV-22.

ta ta for now

ok so in the low band encryption/static-chirp category i have one addition
i feel confident on, 38.05. new one to me. 1700-1900 window. i got myself
to a good elevation point, and watching signal strength indicators
concluded one transmitter relatively close, 4-5 bars, and one distant 0-1
bars.

how close or distant? who knows. i don't even know what it is i am
listening to/nature of the transmitter. prior to the original report of
43.0 "go red" and then recently my hearing voice comms followed by my
"mystery signal" on 43.0 i had decided it was some sort of data signal.
having only heard digital P25 encryption i had kinda been expecting a more
structured signal.

the other part only kinda relates. 140.85 (AM) had been caught in some search
and stores and yesterday afternoon i caught a good bit of traffic on it
with a good clear signal. It was Flight Check 27 though a different pilot
from the 44.8 one. And yeah nothing terribly exciting. they're shooting
GCA approach's some where withing radio range and trying to calibrate a
radar. nothing more on 44.8 but 140.85, 119.65 were used, and at some point 27 asked
what they wanted to use for UHF, and of course only caught part of the
readback which he said "two five two two". so i dutifully punched in
225.225 and 325.225 and have heard nothing.

now the kicker: while i yet to hear anything (relevant) on this frequency, (but
it was repeated clearly multiple times, cause one side was having trouble
hearing the other on it) they were also using 47.125.

hmmmmmm

I wonder if any DOT guys are receiving on open squelch. or perhaps the
statistical odds of a coincidence actually indicate a FAA-DOT-GCA-FM-BFF
situation? 44.8 a DOT freq anywhere? hmmm. oh well.

i know, i know, nobody cares, sit down and shut up, yes ma'am i'm sorry.

a mildly interesting update on 140.85 (AM): after the initial day hearing it, silent ever since. well it had keyed up a number of times, but only static, prob RFI somewhere? well yesterday the static was clogging up the works so outta curiosity on the 668 i added 140.85 NFM with squelch open.

"CAP3213 at checkpoint hotel" etc type stuff. you can never tell what those guys are going to do.
apparently they are assisting with the GCA thing but didn't get enough to tell where tho. Richmond was mentioned but i am fairly certain that its a law that in the lower 48 each state must have 10 towns by that name.

if i catch a PL ill let me know.

LOL... Richmond, Greenwood, Greenville, Jackson.... Madison The most repeated town names, especially in the South. And hear them on VHF Lo in Fall, Winter, Spring... Good luck as this is skip season so unless they mention an actual location you have actual knowledge of nailing it could be problematic.
