It's fun but may be time consuming. Project leader Dan Smith has a page for new developers at :</div><div> <a href="https://chirp.danplanet.com/projects/chirp/wiki/Developers">https://chirp.danplanet.com/projects/chirp/wiki/Developers</a></div><div>I think I'm probably still the newest developer.

Other approaches are required for a "real" serial port cable or for any protocol that is not a real or pseudo async serial protocol. There are also alternatives if you prefer to use Windows.</div><div>Another CHIRP user was able to use my sniffing page's instructions to sniff a Yaesu FT-25, so the page must not be completely incomprehensible.</div><div><br></div><div>After you successfully capture a full protocol interaction, the next step is to stare at the result to see if it looks like any of the protocols CHIRP uses in any of the hundreds of radios already supported. CHIRP code does not formally subdivide the radios based on the protocols, but there are several obvious informal "families" of protocols. If you see a match, look at the actual contents of the memory as conveyed by the protocol to see if it looks like one of the radios that use that protocol, then find that driver and see if you can tweak it to handle the new radio.<br></div><div><br></div><div><br></div><div><br></div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, May 8, 2019 at 1:21 PM Gary Craig <<a href="mailto:gcraig@webcoindustries.com">gcraig@webcoindustries.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

Within the CHIRP code, there is (supposed of be) an "alias" defined for any radio that has the IDENTICAL programming interface with another radio. "identical" means completely indistinguishable, including any internal version or ID string.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:10pt;font-family:"Calibri",sans-serif">If a radio is "almost" identical, then the CHIRP code needs to be updated so it knows the differences. If the radio is truly identical, then you can program it using the original
name or any of the aliases. If you think you radio might be identical and you are very brave, you can try it: please report the result here. If you think it may be a variant, please consider learning how to "sniff" the protocol, and report the result here.
Please do not try any of this unless you are willing to risk temporary or permanent problems with your radio up to and including totally bricking it. (very unlikely but you must take assume the responsibility for this.)<u></u><u></u></span></p>
