Hello fellow Hams Calvin NI5Y I was like most hams getting into using my Kenwood TS-2000 for PSK-31 and FT8 data modes. I found out it was a bit of a pain in the neck to get the radio to work properly. I purchased a Rigblaster Plug & Play with the 6 PIN mini DIN plug so I could use it with my Yaesu FT-950 and Kenwood TS-2000. I purchased the 6 PIN mini DIN adaptor to 13 PIN DIN to use the Rigblaster Plug & Play on my Kenwood TS-2000. The 13 PIN DIN plug PTT is wired to ground PINS 9 & 13. I had to switch the PTT ground to PIN 13 only. I then loaded the Drivers for the Rigblaster Plug & Play and connected it to my PC USB jack and sound card jack. Most Hams have noted they get PTT to work but no transmit audio via the 13 PIN DIN plug in the ACC port. This is what I did to get the transmit audio to work for PSK-31 and FT8 I connected the speaker out jack of the Rigblaster Plug & Play into a mic adapter cable. I use my Heil sound Adapter cable from my PRO-Micro boom headset to input the transmit audio into the Mic Port on the front of the radio.
