[Ham-Mac] Need Help for a fldigi/K3 Interface

[Jack Brindle]

Dick;

The Signalink USB does not have a USB-serial interface, only an audio one. It uses the built-in Mac audio software, and thus needs no serial drivers.

The Signalink has a built-in VOX that triggers the PTT signal from the transmit audio. This sounds like the transmit audio levels are not set up properly in the repaired mini, or something else has changed, like perhaps the audio out level or microphone source selection in the K3. The PTT output is obviously wring on the SL, but no audio is going to the DSP in the K3. My first thought is to check the K3 sources.

When he opens the fldigi-3.21.76 Rig Control configuration panel, the SLAB_USBtoUART Device is not visible. Maybe the K3 uses a different device or maybe there is an issue with his recently repaired Mac by Apple?

>> I have been using a SignalInk USB for the connection between he computer and radio.  It plugs into the radio and the cable goes into the SL.  Then it goes out of the SL and then to a USB port on the computer  It has a volume control for both TX and RX/ volume.  I have used it with the K3 for several years since I bought  it.  The RX seems to through to the computer with the volume control and it is still working fine.  The  TX control goes from the computer and usually show a PTT red llight on the SL and the red light on the K3.  However now it shows the red light  on the SL USB and the  K3 but no power is shown on the power meter on the K3 or on the separate power meter.  I am wondering if it is still working on TX?
