[chirp_devel] [PATCH][BTECH] n8: Fixed a bug on the upload (BTECH UV2501+220), fixes #3015
by M.Sc. Pavel Milanes Costa 01 Apr '16

01 Apr '16

The BTECH UV2501+220 has a trick on the upload, it must push an ACK and get two bytes, ending with an ACK; this just before the data upload. Also the first block of data to upload must no start with an ACK.

Some radios like the BTECH UV2501+220 (and others) has a second id. Just a special string on a high zone of the mem, I improved and simplified the handling of this extra ID for the BTECH UV2501+220.

[chirp_devel] Btech driver and JT2705M radio
by David Fannin 01 Apr '16

01 Apr '16

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 (ascii) 06 01 03 06 01 07 04 04 00 00 04 08 00 W H K J H T Y 2 8 8 H 2 8 8 5 4 U 8 8 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 U Suggestions? thanks, Dave
