First, the good news is fldigi-3.21.11.dmg works with my Kenwood TS-590S using, the direct USB interface to an iMac using the Silicon Labs USB-to-UART VPC Driver - provided I use the fldigi RigCAT option for rig control.
The bad news is I have not been able to get the Hamlib option for rig control in fldigi to key or cause the TS-590S to transmit. I suspect the reason it will not transmit is the Hamlib option for "PTT via hamlib command" is checked but the option is dimmed or not active in the fldigi configuration panel. Dave W1HKJ, has not been able to duplicate problem most likely because he does have a Kenwood TS-590S and may not use a direct USB interface in his development setup. One guess was the problem could be related to the Silicon Labs USB to UART VPC driver used by Kenwood for the TS-590S and Icom for the IC-7410; however, RigCAT does not have an issue with this driver. For this reason I tend to discount the SL USB-to-UART as the problem child. I had no problem using the Hamlib interface when I used the SignaLink USB via the TS-590's Acc2 port. Keying the rig was handled by the Auto-PTT circuit in the SignaLink USB. There was no reason for me to check the box to "PTT via Hamlib command" and I never noticed if it was dimmed or active. I first noticed the inactive or dimmed out PTT option when took the SignaLink out of line and went to the direct USB interface for audio and rig control. When Hamlib would not transmit, I switch over to RigCAT that works but does not report VFO-B frequencies for DX split operations. When Dave W1HKJ could not duplicate the problem, I assumed there may something wrong with my setup so I started over as a new user. I let the fldigi Wizard do its thing and when it presented the rig control options, the PTT option was not dimmed in Hamlib. I selected it and when I pushed the red initialize button, fldigi crashed - hung - big time and I had to use the OS X Force Quit to escape. When I restarted, the PTT option was checked but the option was dimmed and fldigi could not key the rig. I have seen notes from Nate N0NB about a new version of Hamlib. Has the new version been tested with fldigi? I wonder if the new version will correct the noted PTT issue. Nate indicated Hamlib keys his K3 via a USB using his old .fldigi folder but I don't know how his K3 setup relates to a Kenwood. Someone mentioned there could be a port ownership issue with RigCAT or the Mac OS owning the USB port and not releasing for use by Hamlib. I have no way to assess or test for port ownership. I could not get Hamlib to work as a new user. Has any member of fldigi alpha team recently tested the Hamlib option to "PTT via Hamlib control" via a USB port? Anyone else using one of the Silicon Labs USB to UART drivers with Hamlib for Window, Linux and Mac OS X? http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx How about some feedback from another fldigi Kenwood TS-590S or Icom IC-7410 user with the USB interface? I am open to any suggestion to get Hamlib working with the Kenwood TS-590S USB interface. I don't think the Hamlib PTT option in fldigi should be dimmed out.
