New to GMRS - neighborhood watch
SteveShannon replied to WRXY704's topic in National and Regional GMRS Nets
Or, when trees are blowing down how do you keep your antenna up? -
Welcome, Paulie!

How does anyone know you have a Credence Clearwater Revival unless you tell them? Practice saying Motorola. You want an ECR? Expensive Chinese Radio, or do you want something not made in China? Wouxun is an ECR that’s pretty highly considered. It doesn’t sound any different than a UV5R though. My Garmin Rhino is made in Taiwan, which is the other Chinese government, but definitely not our communist foe. It’s very well built, but will not allow the antenna to be interchanged. It has the best screen of any radio I have.

Radioddity Scan Features Question
SteveShannon replied to WSFJ540's question in Technical Discussion
There’s a scan group. Go to a channel and hit SCAN ADD then select On or Off. You can add memory channels to it or take them out of it. Then, whenever you scan, the ones that say “On” will be scanned and the ones set to “Off” won’t be. -
I’m out. You couldn’t keep it candidate free.

I guess it depends on what you call rigged and which “New World Order” you fear most and whether you think the country will look exactly the same if either candidate is elected in any of the races. it should be very obvious that the outcomes of the races aren’t predetermined. If they were, far less money would be spent both during the primaries and the general elections. But, yes, once the individual parties and PACs make a decision on whom they want to run there’s little individual voters can do but vote for the candidates the machines present us. Until something unexpected happens, like one candidate’s disastrous debate performance and the change in candidates that followed. I’m speaking only about the process of selecting and supporting candidates. I don’t want this to become a discussion that pits members of this forum against each other based on their personal choice of candidates. I will not engage in any discussion about why one party and candidate might be preferable to another. That would get this thread locked, removed, or at least moderated.

Anybody can complain about the government. That’s part of the first amendment, but failing to vote means you missed your opportunity to do something about it. .

So far it’s much slower this year. Only 20 so far.

We get about a hundred each year, depending on weather.

ICOM IC-F21GM setup of two used radios (newbie)
SteveShannon replied to WSDF258's topic in General Discussion
If you're really thinking of spending $75 on programming software, I would recommend spending the same amount of money to get more current radios instead. -
You worry too much my friend. You don't need to apologize. I have no intentions of protesting, no matter which way the election goes. That's just how it works. Whoever is elected will be my president, even if I disagree with them. And in two more years the cycle of campaigning will begin again. If I could change one thing it would be to prohibit campaigning until 30 days before the primaries. If they cannot make their case in 30 days they shouldn't be running.

ICOM IC-F21GM setup of two used radios (newbie)
SteveShannon replied to WSDF258's topic in General Discussion
Okay, but please don’t give up on learning to set and clear tones from the front panel. The Icom is a good radio. Being able to program it from the front panel could be extremely useful. -
Happy Halloween!

Yup, no offset on any of the the non-repeater channels. Good job figuring it out!
-
You certainly haven’t offended anyone yet! If all you want to do is listen, simply make sure all of the CTCSS tones or DCS codes are cleared out and set the radio to scan all of the channels. GMRS and FRS have 22 channels for simplex communications, where radios take turns talking to each other one at a time, so radio A transmits to radio B on 462.550 MHz. When it’s done radio B transmits back on 462.550 MHz. 462.550 MHz is channel 15. There are eight main channels, which are numbered 15-22. They’re actually called the 462 MHz main channels in the regulations. Those eight channels are shared by people transmitting simplex to each other and by repeaters. Those are the only channels repeaters may transmit on and remain compliant with the regulations: https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-E?toc=1 But repeaters must receive signals at exactly the same time as they transmit. So they receive on frequencies that are 5 MHz higher so the received signal and the transmitted signal may be handled separately. Receiving and transmitting at the same time is called duplex (sometimes old people like me call it full duplex but most people simply say duplex.) The eight channels that handheld and mobile radios use to transmit to a repeater are called the 467 MHz main channels. GMRS radios are set up so when you’re tuned to one of the repeater channels your radio automatically transmits on one of the 467 MHz channels and receives on the 462 MHz channel exactly 5 MHz below it. Unfortunately, there’s no standard for how those repeater channels are labeled. Going back to the example 462.550/467.550 channel pair, that is called channel 23 by some radios and RP15 by others. If all you want to do is listen, leave the tone/codes out. But, if you want to transmit through a repeater, you almost always will be required to set a matching tone in your radio or the repeater will not allow your signal through from its receiver to its transmitter.

Provide us with a screenshot from Chirp. Maybe we can see what’s going on. Are you on a repeater channel? There won’t be an offset otherwise.

So I’m not sure how the Retevis RT-10 implements DMR on an unlicensed radio. Where does the DMR ID come from? But, it’s the closest thing to affordable that I could find. https://a.co/d/i96kTIS DMR is not frequency hopping, although many DMR radios have the capability of encrypting communications. I have no idea what the regulations say about that for 900 MHz. Being unlicensed is not the same as being regulation free. The only FHSS radios I found were the Motorola DLR radios. They’re digital and FHSS but not inexpensive. Good luck finding something for your son.

ICOM IC-F21GM setup of two used radios (newbie)
SteveShannon replied to WSDF258's topic in General Discussion
First, for every channel, remove any CTCSS tones or DCS codes on both transmit and receive. Then just change them both to the same channel and you should be able to transmit from one to the other. Don’t try to transmit from one to the other when they’re just a few feet (or inches) from each other. That can cause desensing, which is when the strong transmit power from one overwhelms the sensitive receiver of the other. Put some distance between them. Good luck! -
DMR radios require licensing anyway. Is there some reason why you want the 900 MHz instead of license free MURS in the VHF band or license free FRS in the UHF band? Either can be had for pretty low prices.

(UPDATE) Favorite Magmount Antenna?
SteveShannon replied to Lambda's question in Technical Discussion
I also have MXTA26 antennas. -
Just to clarify, those tones are well within the range of human hearing. For comparison the lowest note on a piano is 27.5 Hz (lowest A). After the tones are no longer needed, but before being converted to audio, radio circuitry filters out everything below 300 Hz to prevent us from hearing the tones.
