It does 2 single tones, one after the other. Like 459.3 and 829.6 Also it will do the group call using a 3rd long tone.

This group call with a long tone of 1050 works great on the weather channels. That way you can leave the radio on at night, and still get alerted if the weather service issues an advisory. Note, when you are on the weather channel, it will not receive anything else.

I don't think it does DTMF decode.

Does the TYT do 2 Tone or 2 Tone DTMF? Our FD does 2 tone but only two single tone frequencies. I imagine that most fire paging consists of a combination of single tones at different frequencies. I remember when I was a volunteer fireman that I only had a pager. And it received the two single tone multi frequency tones depending upon what station was signaling. I guess you would call this STMF toning. I'm pretty sure my Anytone AT-5888UV when doing 2 or 5 tone signaling uses DTMF tones for both encode and decode. And that's not going to work unless the public service entity also used DTMF signaling.

The only Chinese talkie that I know does 2 tone decode like the fire department page, is the TYT model TH-UVF1 like this one. http://www.kightradio.com/TH-UVF1-Dual-Band-VHFUHF-Handheld_p_78.html

I don't have any thing in this web site, other then I have bought several radios from here.

Thanks Jim, that did the trick. I did figure out what "tuning
step" meant around 3am, but didn't want to write back and admit
that I was still up and obsessing over it :) I'm glad I went to bed.

I have all my channels configured now, except for the "page"
channel on the Icom that I wish to emulate in the Baofeng. In
the Icom, the channel is muted until it receives a 2-tone page
signal. I can see how it is set up in the Icom CS-F14 program,
but I'm not finding any functionality like that in CHIRP. When I
click on "Settings" in CHIRP, I only get a blank field. Can I do
this in CHIRP? I see nothing in the wiki about functions like this.

And, perhaps similarly, in CS-F14 under Common>Set Mode there is
a squelch value variable that has been set to 125. Is that
something I need to set in the UV-B5?

Thanks much! Doug

Doug,

CHIRP will program a great number of brands and models of radios. Each type or radio (or family of radios) needs a specific driver that matches up to that radio's capabilities. CHIRP cannot make a radio do something that is isn't capable of doing. In this case, the UV-B5 (or any of the Chinese radios that I am familiar with) are not capable of decoding a 2-tone page signal. So you won't see that functionality for the UV-B5 in CHIRP.

You will only be able to use a CTCSS tone or a DTCS code for selective squelch operations. But be careful setting up a receive tone or code. If you don't know how to do it properly, your settings could wind up programming a channel that will never hear anything. Having no Rx CTCSS tone or Rx DTCS code always work (but you may hear other station on the channel that you may not want to).
