What's in this update
Restrict the changing of the band or detecting a band error to a time window of about 20 ms after the PTT is energized.
When Operate mode is selected by the operator, a band cable input if any, results in the band selection to revert to the band as input through that cable.
If the remote computer control connection changes to the operate mode, if the 4 bit band control cable is connected then the filter will change to that selected filter, or if the ICOM voltage control cable is connected the filter will change to that selected filter.
The AM1; command to select operate mode needs to be sent twice when the band filter has been set to the wrong value. (The second command to select operate mode then changes the mode) Add the detection of additional band frequency changes that return the amplifier to the standby mode when there is a change detected going from one band to another band and also in direct keying mode.
The 160M 80M and 6M band changes are handled by the filter select handling process already in effect.
The Kenwood and four bit band control will now include detection for changes between 30M, 40M, 20M, 17M, 15M, 12M, and 10M bands.
The ICOM band control cable will be able to control changes between 30M, 40M, and 20M bands.
The ICOM band control cable does not distinguish between the 10M and 12M bands, or the 15m and 17M bands.
