This release - when controlling a Kenwood TS480, TS590, or TS2000, polls to determine which VFO will transmit so that the (TX) indication on Commander's Main window is accurate (tnx to Tim NZ8J) - when the primary transceiver is a Kenwood TS-480, TS590, or TS-2000, optionally provides A/B and TF-S buttons instead of AxB and XFC buttons (tnx to Tim NZ8J) - provides an option that when enabled directs a TS-590 to transmit from its ACC2 input rather than its MIC input - adds the FT-5000 to the Secondary CAT Port's Protocol selector (tnx to Joe K2XX) - enables a FlexRadio connected to the Secondary CAT port to lead the primary transceiver (tnx to Chris NJ5N, Bill AB4BJ, and Gary AB9M) - when the secondary transceiver is a Kenwood, Elecraft, or Flex, ensures that it identifies itself and is directed to report frequency and mode changes (tnx to Chris NJ5N, Bill AB4BJ, and Gary AB9M) - when the primary transceiver is a K3 equipped with a subreceiver and the Main window's Dual box is checked, provides a Dual Track checkbox that when enabled directs the subreceiver frequency to track the main frequency (tnx to Joe W4TV) - when the primary transceiver is a K3, provides a "RTTY submode" panel on the Config window's General tab that allows the user to specify FSK or AFSK; this panel's settings determine whether to place the K3 in FSK or AFSK A when Commander's mode is set to RTTY or RTTY-R, and are made available to other applications (tnx to Joe W4TV and Rich VE3KI) - makes the currently-selected radio's 2-bit ID available to other applications (tnx to Joe W4TV) - provides parallel port support on 64-bit flavors of Windows and handles parallel port base addresses up to to FFF0 (tnx to Joe W4TV and Koen ON7RK) - provides the ability to directly specify a Parallel Port address (tnx to Joe W4TV and Koen ON7RK) - accepts and commands in user-defined command sequences (tnx to Dave G4MUL) - updates the ChangingFrequency.htm, ChangingMode.htm, CommandSequences.htm, Configuration.htm, and ControllingMultipleRadios.htm documentation files Notes: 1. For K3 users, new "RTTY Submode" panel defaults to FSK; if your RTTY startup macro in WinWarbler includes CAT commands that place your K3 in in FSK or AFSK A, these commands will take precedence over the setting in Commander's "RTTY Submode" panel 2. to use A/B and TF-S buttons with your Kenwood TS-480, TS590, or TS-2000 instead of AxB and XFC buttons, check the "provide A/B and TF-SET buttons" box in the Radio panel on the Config window's General tab Commander 8.7.7 is available via the DXLab Launcher and via 73, Dave, AA6YQ
