Back when I was writing software for “real-time” telemetry systems in 1992 or 93, I was assigned to write a routine that would identify stale data for electric utilities and change its color on-screen in the SCADA HMI (we weren’t very correct back then; we called it an MMI). Detecting stale data could be used to identify a sensor that had stuck somehow, such as pond level sensor in a hydro reservoir. “Pedantic” is my middle name!

When you say the setup will not talk more than 2 miles do you mean that 1. Transmissions from the RA87 cannot be heard beyond that range, or 2. The repeater will not receive transmissions from other radios beyond that range, or 3. Both.

A repeater in the myGMRS database which has had no data updates in over a year. The repeater might be just fine or not. Old data in a database is called “stale data.”

I think it is the manufacturer’s fault: https://www.amazon.com/TIDRADIO-TD-F9GP-Handheld-Upgraded-Kits-Black/dp/B091K1G9FZ

No. It’s a GMRS radio.

That’s really not “very poor.” 3.0:1 still means that 75% of your power is going out of your antenna.

Hams going out into the field sometimes lay down aluminum screen and place a ground plane antenna on the screen. They also use a product sold as “Faraday cloth.”

Yes

Why not just take the logical step from the Radio Merit Badge to earning an amateur radio Technician license?

How about menu 9: BEEP? And if not then menu 20 and tell it not to send an ID. You could be sending an ID at the end of PTT. This has several options. You want to turn it off.

Attributing this to sloppiness is presumptive. I wouldn’t be surprised if all the tone frequencies in the radio are based on a single oscillator. Components fail. That’s just a fact of life. Show me any manufacturer that has a perfect record.

There is no official channel. Some people have suggested 19, but millions of people can’t use it.

So we’re all of the tones incorrect? 10%, 50%, ? Did you see frequencies that were off also?

Or just push the PTT on the repeater channel and ask if someone hears you … Wake me when all is well with the universe. I suspect 80% of the tones on RayP’s radio were just fine.

All of the control functionality (such as tone encoding and decoding) except the RF front end is probably integrated into a chipset though, so in that sense it is a rig on a chip. Some radios (including Baofengs) have the ability to scan for tones. You could try transmitting every single tone while a friend of yours scans your signal to discern what tone you’re sending and make sure it matches. I make no guarantee that the friendship will survive the exercise.

I don’t think they intended to. The first post didn’t appear when I looked for unread posts until yesterday, even though it was posted Sunday.

I’m not, but when I went back to school the second time (because I failed to hand in assignments that were imperfect) I had to learn how to accept imperfections and make decisions. I had to learn to accept good enough instead of holding out for perfect.

I don’t know what Ray is talking about. I’ve never heard anyone else knock Wouxun for poorly functioning CTCSS. Just use the radio. Stop obsessing. Or set yourself up to be a communications service shop and buy a Communications Service Monitor: https://www.ebay.com/itm/374764319457?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&mkscid=101&itemid=374764319457&targetid=1530766779295&device=t&mktype=pla&googleloc=9021317&poi=&campaignid=19851828444&mkgroupid=145880009014&rlsatarget=pla-1530766779295&abcId=9307249&merchantid=8317664&gad_source=1&gbraid=0AAAAAD_QDh__asFTIQ3LwjckorkT9KnHA&gclid=Cj0KCQjwncWvBhD_ARIsAEb2HW9BC-CZAJgJEhs5gnqWCwUxrJCQcF4n8PYDMz4cJnx52S0j0biIhgkaAjdCEALw_wcB

Nobody does that. They’re right. CTCSS is an actual tone. DCS is a digital code. The mistake some people make is depending on numeric designators for the tones. Motorola only had 38 and they used numbers 1 through 38 to refer to them, but most other manufacturers have added a few extra tones so it’s crucial that you look up the actual tone, such as 100.0 Hz, and use that to ensure you’re comparing apples to apples.

You’re gonna need to tell us what you’re talking about. How do you test what?

I had to go look. So many things about his question sounded like the other thread. I discovered that it’s the same guy. He posted this question Sunday and in the same sub forum he posted the same question Monday. The Monday post got all the love, but the Sunday post didn’t show upon my device until wryc373 commented. Strange.

And DPL is the same as DCS or DTCSS.

It’s there today:

Q1. No. It doesn’t work like that. You would need two radios and a duplexer. Q2. Two radios plug into the high and low ports. For GMRS the receiver is plugged into the high port because it receives on the 467 MHz channel. The transmitter plugs into the low port because it transmits on the 462 MHz channel.

Just use one of the simplex channels (1-22) and add tones.
