Since you are using a Yaesu FT-2980, you might be driving it with too much audio into the microphone jack. When I had my FT-2980 in my go kit, I had a Signalink USB, but I had to keep the TX volume very low to keep from overdriving the transmitted signal. My VARA gateways use Digirigs but they are going into the 6 pin data plugs on their respective radios. Also the FT-2980 will do most of the VARA Wide speeds. I've achieved 19k bps when I had mine set up for Winlink/VARA connections. I always get confused with which set of Ping values are for which station.
