I suspect that hams and other experience and INTERESTED radio users can get reliable comms with portables over a greater range than the people who just use them as tools. We detect noise and automatically adjust our position, orientation and even speech to optimise the path. They don't. Digital means it will be even worse because the clues are missing.

Has anyone got an up to date listing of their official channels and I'll give them a listen here where we have a well funded group with decent people.

You're quite right, their MO is offering medical assistance, not radio. As a user service though, going digital would seem to me to be a strange decision, not to mention expensive. I wonder what the reasoning is behind it?

Data protection act, to accepted into the emergency services club they have to be able to pass sensitive information in a secure manner.
NXDN/Nextel/Iden have digital scrambling as standard - which is decodable using the AOR AR-DV1...

The aor can't decrypt the AES encryption scrambling if it has been enabled , only the 15 bit standard key type as I found out with my local frequency that use it mike so just a head's up if they do use aes etc ;)

The AES encryption modules are an add on plug in that are quite expensive, they would need to have all their radios fitted for interoperability.. Don't think that matches the £250 per radio price tag..

Have found what I think is a cab company on an oddball frequency using AES encryption and you are quite right the DV1 will not touch it..

Yeah I found out the hard way mike , especially after having to buy a dv1 just to test the theory out :) , I'm also still trying to find some software that will interrogate idas/nexedge systems to see which scrambling security there using but so far I'm coming up with blanks and not finding it available anywhere ?

I don't know of any, my info tends to be from service engineers I have worked with and still keep in touch..
