2-Tone - IC-F221 / 221S

[W1RH]

I've programmed many, many radios for 2-tone encode and decode, but this is my first Icom.

My question is: How the heck to I get the radio to recognize the 2-tone page with an audible alert out of the speaker? The tones are correct. I have the timings at the default settings. I'm testing the radio using a Motorola HT-1250 to generate the tones. Vertex, Motorola, Kenwood and Tait radios all decode the tones without issue.

Any suggestions will be greatly appreciated. I am using the latest versions of software for the 221-1 and the 221-S

You need to turn on the RX 2 Tone decode (up to 10) in the memory screen on a per channel basis.

Bob, I have both a ic121 and ic221 xcvrs. I can send you a code plug that has the default settings.
When I monitor public safety comms, sometimes the sound of a siren will cause the radio to
beep and the display flash.

Just a thought, for you.

12db: Yes, I did do that when programming the radios. No audible alert when the radio is paged.

Jim: If you have a radio that issues an audible alert when paged (2-tone), yes, I'd like the file. Good to hear from you.

The other thing that could be going on is the 221's are famous for drifting off frequency far enough it will not decode 2 tone or even PL. If you have the means, check the RX/TX. I've seen it many times with these radios and may need to be brought back into alignment.

Bob, check my posting on Oct 13, 2019. I UPLOADED MY Codeplugs for the ic121 and ic221.
It is 5 or so pages inside this topic.

Jim: Got your file. No 2-tone programmed into it.

12db: I'm having this issue with every 221-S and 221-1 I have here. I do have a service analyzer. Transmit tones received OK when sent from an Icom F221 to Vertex and Motorola radios. Got to be something I'm doing wrong.

Have you tried the hangup michrphone ?

Great idea Jim, and I was sure this would fix it.....but still no 2-tone decode. Tested on two different radios. One F221-S and one F221-1. Verified hangup was grounded by testing scan.

Any other suggestions?
