Pavel,
This may be part of the confusion. The Juentai site says:
General specification:
Frequency range
VHF:136~174MHz
245~245.9875MHz (220~260MHz)
UHF:400~490MHz
I believe that's 220-260 RX and 245-246 TX,
Hi to all, some news about the patches in the development queue and
some other infos.
The btech driver (for all supported radios looking similar to the
btechs) has a bug about the driver not retrying the identification
(aka: the driver does just one attempt) a patch for fixing that is
on the queue, the driver will do 3 attempts, all due to a line not
being tabulated correctly. (sorry, my fault)
That must fix what some user are reporting as "not working in the
first try" or "not working from a cold start"
A new generation for the BTECH UV-2510+220 was discovered today, if
any of you had faced a "Radio identification failed" error with this
model you must try the next daily of Chirp that will contain support
for this new version, all points that this is a second generation of
the BTECH UV-2510+220.
Mental note for you: If you found a BTECH like radio that is
supported on Chirp but it says "Radio identification failed" you may
have hit a new variant, go to the chirp forum and left us a issue
with a debug.log attached, that will speed up things a lot. (search
in the chirp's wiki for "how to report a bug" for instructions)
Support for the Sainsonic GT-890 is waiting on the develop queue to
be applied also.
Some users have experimented problems working the Juentai JT-6188 Mini
with Chirp, we realize today that there is a new spin on this
radios: the Juentai JT-6188 Plus. If any of you has this new
Plus radio we are willing to work with you for get it
supported on chirp, just drop me and email.
This is getting the users confused as Chirp listed the JT-6188 Mini
as a Clone of the QYT KT8900, but the new JT-6188 Plus is a
totally different radio and is not supported by Chirp yet (this new
model has 220Mhz and a fan)
