Trying to have "private" communication.

[WA4DIS]

Forgive the MURS newbie here please.

I am trying to set up a "private" net for my property. I understand there is no real privacy but I don't want to hear people outside our property. I have tried using CHIRP setting tones and sql and any other settings Google, (yeah, I hear ya) told me.

Note: I am using baofeng uv-5r radios. (Yes I am aware they are not technical "legal" for MURS.)

Any assistance would be greatly appreciated.

Thanks.

Using the Zello app on cell phones would be a good choice for secure comms.

Cell service/wifi is not an option.

I'm not really sure what you are doing as far as a coded squelch setting. If you set the same CTCSS (Continuous Tone Coded Squelch System) or DCS (Digital-Coded Squelch) code in each radio, you should only be able to hear each other, unless by coincidence someone else nearby is using the same code.

IDK either. LOL
If I set the Tone Mode to TSQL and then try to set the Tone and Tone Sql, it removes one or the other.

Of course the comms is not private as anyone with a MURS capable receiver can monitor the transmissions. Also, if @WA4DIS is communicating with one of their like coded radios, they could receive interference from an external party since their squelch would be open.

@WA4DIS, is this for personal use or business use?

personal on my property between other family members.

Looks like you are using CTCSS tone 67.0. Use the same setting in each radio and you should be good to go.

I have radios A and B with those settings, and radio C without any special tone settings (acting as the outsider radio for testing), and A and B can still hear C.

Better quality radios with reliable CTCSS/DCS decoding...or better yet, some low cost DMR radios with your own custom talk group settings and...wait for it...basic encryption. Some of the AnyTone radios support AES-256. No one with a scanner will stalk your family on those.

You are doing it wrong. TSQL sets the transmit and receive tone. Tone sets only the transmit tone. Use TSQL.

This appears to be a Baofeng specific programming issue. I'll leave it to others that are familiar with these radios. Good luck!

Make certain radio C isn't transmitting any tone (or set it to transmit some tone other than 67.0).

Than make certain radios A & B are set to enable tone receive (TSQL).

If set up properly, Radios A & B will be able to hear each other, but not hear Radio C. But Radio C will hear both Radios A and B because it does not have tone squelch enabled.

That's above my budget. I just want a simple communication net between the house and the barn, without hearing any other MURS hikers or whatever may be nearby. I don't care if they hear me.

You are doing it wrong. TSQL sets the transmit and receive tone. Tone sets only the transmit tone. Use TSQL.

Here are Radio C's settings,

I appreciate your help.

Not legal in the USA without a business band license.

Make sure you are not testing the radios right next to each other.

Make sure you are not testing the radios right next to each other.

If they are all on the same simplex frequency then being close will have no effect.

I've had direct sampling CCRs exhibit weird behavior at close distances. I have indeed seen this particular type of issue when testing radio programming. i.e. I have had a CCR with it's squelch set for tone open from a transmitter NOT set to transmit a tone. I have also seen properly programmed CCRs not open tone squelch when properly programmed but operated right next to each other. It's not common but it has happened to me with these junk radios.

I moved the radios ~30 feet away from each other and still not working as intended.

<snip> I just want a simple communication net between the house and the barn… <snip>

How far apart are the house and the barn? Maybe we are over complicating the need. There are other ways to have everyday comms between two structures. Perhaps we need to think outside the box. As I see it, the system requirements thus far include the following:

• House to barn comms needed
• Distance is to be determined
• Does not want to hear other people in the area talking if using a compatible system
• It is okay for others to hear the house to barn comms if monitoring with a compatible system
• Whether point to point comms or point to multipoint comms or multipoint to multipoint comms is needed in the house and barn is to be determined
• Number of subscribers that will use the comms system is three but need to confirm
• Whether comms is required outside of the house and barn is to be determined
• Whether the system needs expansion capabilities is to be determined
• Whether there are other requirements is to be determined

So thinking outside the box, what other comms solutions exist that meet the requirements?
