New secret radio band

[PhulesAu]

Kinda lost in the shuffle is the FM mode on newer CB radios hitting the market in quantities. For those who need a short range communications solution, you might look in to it. It has the advantage of a level of security, because of the lack of it's popularity.

If you need to send a secure radio transmission, this easy and free solution is pretty cool.

I'm using an Alinco DR-735 with a digital board for secure comms. It only required plugging the board and a few key strokes for operation. Additional security is there were only a small number of the boards built and our group has about 20 percent of them.

Has anyone had success programming an Anytone AT-D878 in DMR mode? These radios have been more difficult to understand the programming than any I've ever seen.

I would say Chirp software if you haven't already tried it.

That would be too easy, if it worked. It doesn't support the 878.

I knew there was an answer that's not what I suggested.
Maybe someone else will jump in.

Has anyone actually tried FM CB yet?

One of the 'most secure' means of communicating is remaining incommunicado...

I'm not sure what your question was, but here goes. FM modulation on CB radio bands might be considered to be somewhat secure until such time as sales of CB radios with FM capability becomes popular.

Basically, only encryption is secure (assuming you protect the decryption codes) but is closely guarded by the FCC.

My view...the CB radio band (27mhz) utilizing.available modes of modulation, AM, FM, SSB is useful in emergency situations because it is easily monitored - or at least will be when FM transceivers are more available.

Ham radio transceivers can provide more "secure" communications on higher frequency bands and utilizing alternative modes of modulation, although again, without encryption, no transmission is really secure regardless of mode of modulation or frequency. Of course, Ham radio requires licensing but the process is much easier than it was in the past.

Not sure any of this helps you.

The 1.25m band, found only on some tri-band HT's, could also be considered a "secret" radio band for short range simplex FM communications.

The addition of the digital board on the Alinco DR-735 provides reasonably secure voice communications as there were only a small number of digital boards built by Alinco. Communications in the digital mode are unable to be received by radios without the digital board installed.

I'd estimate there are close to 2000 repeaters using this ham band.

But actually finding one on the air, is a real challenge .

A quick check shows over 60 repeaters on this band on the air in Texas a few minutes ago. It's a large state, only 3 or 4 are near me.

I've looked at the repeater guides, but actual on air machines are hard to find some times.

A repeater book only lists repeaters, look online for a list of repeaters actively on air, close to you. Wish I had found this resource before purchasing a repeater book.

Not one I can hit with an HT... For that matter, I haven't been able to hit one at 50w.... Closest 1.25m repeater to me is 64 miles.

I like the app better...

Cell phones also have the same problem.
