Today I connected the TS-2000 to the Radio Boss from Green Heron. I struggled with the 13 pins connector on the back side of the TS-2000. Receive audio was no problem, transmit audio was. At the end I found out that the audio only goes through the radio if you put pin 9 of the 13 pins connector to ground (TX). My mistake was that I Tx-ed with the foot switch connected to the front connector of the radio. I thought transmit is transmit but that’s not the case….
Now I can use WSPR to study propagation on HF and 6 meter.
