Re: the TS2000, I've had one since 2011. Early on I got an xref from VK3HZ. It stabilizes the 2000 perfectly from a 10MHz GPSDO but unfortunately they are no longer available. The DSP is off freq about 1.7Hz, not a biggie. Also the sub band is only AM/FM so there are no SSB digi modes usable there. Sub rx does tune 118-174 and 220 to 500MHz (AM/FM only) but no TX there except in the 2M and 70cm band. If you're using UHF for small signal work you should probably use an amp at the antenna. I've had no issues with mine except one time it stopped accepting audio input on the AUX2 input correctly. I rectified it by resetting the unit. Yes, there is a spur on one of the satellites that's objectionable. I've heard the 'menu' button can get erratic, I've been careful with mine, I'm sure some can be brutal with that knob, it's easy to use to change freq fast as well as menu items. There's lots of features I've never used with it. Minimum of soft keys is a plus in my book, most things are right on the front panel. The DSP shift and bandwidth is functional but probably not the best. It is an old design.
