[chirp_users] Tuning step roadblock

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.

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

                  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.

>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).
