I have a marine radio that needed to be replaced. I bought 2 new radios and programmed the proper frequencies into each of them. Both new radios can transmit and receive to and from the old radio but the 2 new ones neither transmit nor receive between themselves. What can the problem be? It's a mystery to me. Thanks

Is there a CTCSS, PL or other squelch code programmed?

I think we need a clarification:
This is in the Amateur Radio forum, as in the hobby amateur radio.
You are talking about a "marine radio" (VHF Marine or HF Marine?)
Then you mention "programmed proper frequencies into both of them". Marine radios come pre-programmed for the ITU specified marine VHF frequencies and do not require programming. Radios that require programming are usually amateur radios or commercial radios.
Sounds like you are talking about 3 different not necessarily compatible radio services. Giving us more details would help immensely.

Yes. The proper codes were programmed into both radios using the same program template.
I posted to this forum because I thought the amateur radio forum would have some knowledgeable people who could answer the question for me. Even though marine radios are not in the amateur spectrum, the principals of radio would remain the same as far as I know. Unless I'm mistaken, it's not illegal to program your programmable radio to the marine frequencies.
This runs up the RED FLAG.
What do you mean by that?

You may be mistaken.
Depending on what country you live in, the rules can vary. If you are in the USA, FCC Type Acceptance is something you need to consider. The FCC Part 80 (Marine radio) rules require that all radios used in the service have a Type Certification for Part 80 use. 80.203 covers that:
Electronic Code of Federal Regulations (eCFR)
Electronic Code of Federal Regulations (eCFR) published by the Government Publishing Office
www.ecfr.gov
Radios intended for use in the amateur radio hobby rarely have any type certification on their transmitters, as it's not required.
"Commercial" radios often only have Part 90.
A -lot- of the cheap Chinese radios have no type certification.
So, depending on exactly what radio you are using and where you are using it, it may very well be illegal to program those into your radio.
No one is trying to bust you over this. We're attempting to gather enough information so we can provide you with an accurate answer. What you chose to do or not do with that info is entirely up to you. None of us are the "radio police" here, and most of us really don't care what you do. We will, for the most part, attempt to accurately answer your questions.
Thanks for the information.
Of course if you only receive and NOT transmit you can listen on any radio.

The closest to radio policing I get is to consume coffee and donuts while sitting near my Yaesu FT3D.
Had we got to the part yet where we ask "which radios do you have?".

Here in Australia, even having a "non approved" radio can be an issue, even if it is NEVER used for TX.

Same here in the US on some services. Having frequencies programmed into a Part 90 radio that the licensee is not properly licensed for can be a problem. A shop was busted last year for doing that.

Nope. Trying to assist, but I cannot make anyone accept help if they don't want it. Might be an easy fix….
I think this should probably go in one of the Commercial Radio forums.
To the OP, if your radio is a brand listed (Motorola, Kenwood, Icom, etc.), please post your question in the appropriate brand-specific forum. If it's not one of those brands, post in Industry Discussion. Either way, provide as much information as you can: make and model of the radio, what frequencies you are trying to program, at a minimum.
And, with that, I'm locking this thread.
