From the 2023 thread:

Freemor said:
QTH south west New Brunswick Canada
15:30 UTC and 15:40 UTC

31.325 Odd pulses. MFSK?
31.480 Voice (talking about street locations but didn't sound taxi related)
31.975 Sampe type of pulses as 31.325

Image of those odd pulses attached. Will try to get a baseband recording next time

31.325 and 31.975 are French - they are signalling systems for turning on and off public utilities. I hear them via Sporadic E regularly. 31.6875 is another freq they use.

Thanks, I receive these regularly when conditions are right, but didn't know what they are until now. Some kind of SCADA/telemetry was an obvious guess but very interesting to know what they actually are.

If you have a high quality sample, it would be interesting to have this in SigID wiki too.


edit: Sorry for messing up the quotes. I hate these new fancy forum editors.

Another regularly seen data-like signal, does anyone recognize this? About 17 kHz wide, apparently FSK.

Right now on 32325 kHz and 31575 kHz. Sometimes also on 30.0 MHz.

This is not always there and its strength varies so I think it's not local.

Sorry for multi-posting but this doesn't allow me to edit my previous post?

Several RTTY-like signals right now (13:00 UTC):

31450 kHz (possibly two overlapping?)
31475 kHz (also saw those French polytones here)
31500 kHz

Shift is about 130 Hz but no luck with decoding. Tried baud rates 45 ... 100 bd.

Hi Forum,
Just a quick question from a cold UK - Back in the 90's Low Band monitoring was great fun listening to Police, Fire etc from the US.
Obviously conditions haven't been fantastic , but the posts have motivated me to see what there is to hear in the 30-45 mhz area.
Hope this isn't a dumb question , but are the low band freqs posted mainly FM or AM or a mixture ?
Thanks in advance,
Kevin ( East of England)

FM, hence the PL/DPL's being shared
AM would not have PL/DPL
