Stumbled upon this 380MHz freq in use

[robbage]

381.600 FMN. I noticed this freq while sweeping the last couple of weeks. It was very strong (120 out of 100 according to WinRadio) but very infrequent; in the western suburbs. Two-way simplex. Probably not overly entertaining but interesting frequency. I'm just guessing here but possibly active over the next few days.

From the ACMA database
No matches were found for your query.

It is either a transmitter on that frequency or it's like what I have found with my radios, it is receiving a transmission from another frequency on that frequency. Similar to interference, but it has it's own technological term that I can't seem to remember.

I get weird transmissions on my handheld motorolas on CB, usually around CH 25-26-27, kind of like a constant interference, but very strong, and seems to be central to certain locations, as the constant interference becomes intermittent and kind of pulsating the further I move from a location...

Definately some weird transmissions out there

Cross-modulation?

[robbage]

It's definitely on that frequency. Also, I got a hit on that freq at the ACMA database. You're possibly using the wrong postcodes

380Mhz = miltary band.. prob some opp out of swanbourne.
back when i worked for a commercial comms company one of our customers was military and trying to supply radio's to them was a mission as the manufacture asks 20questions as to why you need one in that band.

[robbage]

That's definitely a possibility, which is why I didn't want to say what the communications were about. Don't fancy the men in cams knocking on my bedroom door

(waves to men in cams )

I came across a frequncy in use that was channel 7's Talkback link.

382.700Mhz

Has anyone else recieved the during the news?

[yorky]

Nothing found on the ACMA database with that one either.

[stoz]

i wouldn't think men in cams at swanbourne would be silly enough to let you hear them

That is interesting info, SOR.

Do you reckon they'd be AM of FM (or even both?)
