Scrambling on 446mhz

[Naughtyboy331]

Anyone know which radio is capable of scrambled transmission? and is it simple voice inversion. I heard this today quite strong to me in S. Yorks.

There are different inversion frequencies, so a rig with a single frequency won't guarantee you'll be able to hear them. I think there is software out there which can revert the voice based on any inversion frequency, I'm not sure though as I've never used it.

A number of them now have basic voice inversion, most available one will be the Radioddity R2.

I heard that about 10 miles away. Definitely weren't using 446 sets.

It could be
Baofeng feature Beat Shift 'Scrambler'

Would that do 10miles? Mine are like 1.5w

there are LOTS of 446 sets that support encryption. both legal and not so legal.

it is almost certainly a local lidl / aldi store (I forget which of the two) who
tend to use channel 3 for their staff headset comms - which are encrypted.
its fixed point inversion and dull as ditch-water to monitor

my own cobra branded sets support it

If you have a map of south wales to hand (e.g. maps.google.com)

I was some years ago driving between Shirenewton and Usk along
a hilltop ridge. my cobra set scanning the 8 channels on top of the dash
I heard my mate in Bulwark (Chepstow) call his missus
"Put the kettle on love, just coming back with doggy now"

Recognizing both voices I picked up the handset and chimed in
"no sugar in mine please Joan"

"Whose that ?"
"Hiya its just me - wont be calling in as Im heading towards Usk"

"Where are you?"my mate asked

I told him
"On the back road between Shirenewton and Usk , high ground, heading away
from you"

My mate replied
"b***r off - where are you really?"

I repeated my location , "seriously?" he replied amazed

"Were in the Motorhome , just stopped to walk the dog, were in a lay-by on dartmoor
about 2 and-a-bit miles from the prison"

that was a cobra set used in car to a telcom tw-1000 used outdoors handheld - if theres a path
10miles / no issue

Yes I suppose it is possible in the right conditions, however my location is very low and they were giving positions a good distance away.
