Version 2.03
AT-AUTO firmware version 2.03 includes this change/correction:
(tm)
1. A bug introduced in version 2.02 effectively disabled frequency following via the CAT
port of Kenwood and some Yaesu radios. Version 2.03 fixed this bug, restoring normal
CAT operation with the affected radio types. No other changes were made in version
2.03.
Version 2.02
AT-AUTO firmware version 2.02 includes these changes/corrections:
(tm)
1. Delayed CI-V command execution bug in version 2.01 - In version 2.01, CI-V bus col-
lision detection was incorporated by providing a fixed delay between decoding of the
command and execution of the command. After the delay, if the CI-V bus jamming
sequence (0xFC) had not detected, then the command was executed However, the very
last command was not being executed until the subsequent data string had decoded,
causing the the AT-AUTO
larly noticeable when changing bands using the Icom radio's band buttons and was not
observed when turning the VFO knob. CI-V data decoding and frequency following is
now corrected. This problem did not affect CAT operation with non-Icom radios.
Version 2.01
AT-AUTO firmware version 2.01 includes these changes/corrections:
(tm)
1. Change to the remote control C positioning command - Correct operation required a
third position byte (0x00) or else the command failed. Positioning command is now in
accordance with the description provided in the operating manual (See Table 9.1).
2. CI-V bus collision detection - In earlier firmware releases, the AT-AUTO
sometimes spontaneously QSY based upon collision-corrupted CI-V bus data, which
manifested as an illogical/erroneous QSY frequency. Likewise other bus collisions
would occasionally cause erroneous/unintended AT-AUTO
mand execution.
Version 2.00
The following is a partial summary of bugs found in previous firmware versions (in no
particular order of significance) and corrected with AT-AUTO
to be one frequency change behind. This was particu-
