I've also connected my spare SignaLink sound card unit for audio input for digital modes.
The TS2000 is quite deaf on 70m, but I plan to connect a PGA432 preamp through a 12v transfer relay to improve sensitivity. If I can be bothered, with the low level of 70cm activity, I will move the preamp to masthead in due course. 0.8dB system noise figure is far better than 6 or 7dB!
Maybe conditions will improve and I'll get to work a few stations outside the county........
