looks like the model that was added for the QYT KT-UV980 has a file_id string that overlaps with the JT2705M radio. I'm looking for a solution so I can uniquely identify the radio.

The file_id is KTUV980_fp = "H28854".

The JT2705M has the same string at 0x3f70-0x3f75:

H28854, so the JT file is identified as a KT radio.

Here's the contents from 0x3f70-0x3f9f:

"H288540000000000000000000000HHTYHTY288H28854U880"

For the serial port query/response, here is the JT reponse:

WRITE 55 A5 B5 45 55 45 4D 02

(ascii) U A5 B5 E U E M 02

READ 06 01 03 06 01 07 04 04 00 00 04 08 00 57 48 4B 4A 48 54 59 32 38 38 48 32 38 38 35 34 55 38 38 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 55

Suggestions?

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.
