Hi David,

We have a problem here, one like the baofeng's with his shared ids...

I have a bunch of radios from BTECH, QYT and WACCOM in the driver. The 
BTECH, QYT and WACCOM has a *unique fingerprint* and some times a shared 
magic string to enter clone mode, that's not a problem.

But I have detected two IDENTIC clones (as Magic and Fingerprint concerns):
QYT KT8900     <=> Juentai JT-6188
QYT KT-UV980 <=> JetStream JT2705M

The pair QYT KT8900 and Juentai JT-6188 has an extra step on the UPLOAD 
just after the second ID read, that require sending a ACK, the QYT 
answer back with one byte but the Juentai answer two of them (just like 
the BTECH 2501+220 do) this is a little difference but one to notice.

My solution is making all of them hangs under the same denominator until 
we figure out how to separate one from the another. Just like the 
Baofeng UV-5R do now on the Supported Radios wiki page. With a few more 
iterations not covered in the driver (Zastone, etc..) we may encounter 
some other clones here to.

See the attached file about  the identities of this radios (this is a 
improved work that Jim started and proved of great help)

Dan, any advice on this?

A curious tip: in some magic strings has dates encoded, and you can see 
with the features and use of the magics the evolution of the family if 
you pay attention... This is just speculating: so far Waccom Mini-8900 
is the oldest and BTECH UV2501+220 and UV5001 gen 2 are the newer.
