[aprssig] Group filtering bug in Kenwood TM-D710 (firmware version 2.10)

[Guido Trentalancia]

Hello !

It appears to me that the Kenwood TM-D710 with Operation Panel firmware
version 2.10 (and possibly any other previously released version) has a
bug/limitation within the "Group Filtering" menu settings (APRS) and in
particular it does not appear to be fully compliant with the APRS
protocol specification.

Basically it is not possible to set the above mentioned filter for group
bulletins with group names longer than 4 characters. The APRS protocol
specifies that the Group Name for bulletins can be up to 5 characters
long.

Given the above, at present time, the Kenwood TM-D710 is not able to
filter group bulletins having a group name of 5 characters and this
constitutes a rather severe limitation.

Can somebody please forward this message directly to Kenwod Engineering
or Kenwood Support as appropriate ? Thanks.
