PL tones are all over the place here in Missouri with 100.0, 127.3, 141.3 and 156.7 being the most commonly used tones.

Very good point ! I see it mostly in reaching out to other Trail Leaders when trails are being used used by several groups.

123.025 MHz is air-to-air for helicopters

I don’t see any tone pattern pertaining to different bands in my area. What I do see is a group, club or area may tend to use the same tones regardless of bands. For instance here in San Luis Obispo county the predominant tone is 127.3 and to the south in Santa Barbara county the predominant tone is 131.8. It’s not absolute but certainly the majority.

QUOTED FOR TRUTH. And a big reason I have pulled back even trying to properly and correctly answer this sort of question. I have ONLY been a commercial radio tech for 15 years. There are a couple others on here that have more time in this business than I have. At least one of them posted in here on this very topic. First off referring to an audio connection of a radio as Ethernet, or resembling Ethernet in any fashion.... WHAT??? Maybe it's like a telephone too since the RJ family of connectors is also used. Hell we probably don't even need DSL modems to get Internet. Just plug that Ethernet cord right into the phone jack and it should work just fine. While the racing radio setup does this, it's designed to do it and isn't a simple dual RJ45 adapter. Can it work, possibly. And possibly it will not. It could do any number of things including damage the radio depending on the switching of the PTT, power and other things in that mike connector. It COULD be fine, or it could not be fine. Without seeing the schematics and understanding the circuit for both the mike and the radio, I can't 100% say. I will say that you are taking a chance of letting the magic smoke out of the radio though. So be aware of that. This site has gotten to the point that it chides people that are knowledgeable and their factual and correct statements are frowned upon and made fun of by people that frankly don't know shit and have an over abundance of proving that with their statements. Or they just simply refer to the ones that are knowledgeable as 'some people'. So, do as you like. It might burn up your radio, or it might not. It might sound like crap on the air or it might not. I can promise you this. I don't really care. Others on here have attempted to explain with technical detail why what I just said is correct. Those points were argued by others that I would question if they posses the technical knowledge to make such statements and argue such details.

I honestly haven’t looked at the schematic for any of my mics and none have a speaker but they do have a keypad and led lights so I wonder if this might be an issue. I like @marcspaz’s idea for a Bluetooth mic but if it were me I would constantly forget where I put it .

No, not based on the schematics I’ve seen. The PTT does not connect the microphone to the radio. It’s a separate circuit. It has to be for VOX to work if enabled.

So on the impedance front... Isn't the microphone only connected when the PTT button is pressed? So unless both are pressed at the same time they never interfere with each others electrical properties. I can't say the same if you have speaker microphones because both speakers will be connected and in parallel and therefore cut the resistance load in half (if they are the same resistance)

simplest solution for removable antenna is nmo or even bnc bulkhead on an inspection plate. easy to replace the inspection plate when gmrs/ham/part 90 radio not in use...

This is the most ham radio this GMRS forum has ever looked

@nokones has this correct, talk around only changes your TX while of course using the tones of the repeater, the RX remains the same. Reverse on the other hand does just that, it reverses TX and RX frequencies. Which sounds like what @H8SPVMT is describing rather than talk around.

No, it doesn't reverse anything. The receive freq and tone stays as programmed and the transmit freqs changes to the same freq and tone as the receive freq and tone is programmed for simplex operation.

And some use recorded audio

Or bunions

Perhaps I could have stated that better. It reverses the transmit and receive repeater channels in the radio it is being used on.

Maybe we should start a thread about Hemorrhoids.

I wonder if that would work with the mic and the programming cable.

Nope, reverse is different. Talkaround uses the same frequency (e.g, repeater output) for RX and TX.

I use an RJ45 splitter to connect my KG1000G mic and my bluetooth mic at the same time. Works just fine and everyone says I sound fine. This is what I use

Also known as Reverse as it reverses the transmit and receive frequencies on a repeater channel.

It’s a tad bit more in that it will do this with the tones set for the repeater output automatically without you having to put them in separately for simplex. This makes it useful in my opinion to see if you are within simplex range with the touch of a button. it’s all magic This is my understanding as well.

Yes, with a probability of 97%

There's no way to know for sure without more information, but some repeaters do use Morse code to identify.

Talk Around Is Nothing More Than A Created Motorola Term For Simplex Communications. Nothing More - Nothing Less. No Magic Here......

Sometimes I hear Morse code from repeater that I have tuned to. Is this an identifier for the repeater or does it signify something else. Thanks in advance!
