Let me suggest a WISP work-around for the TS-2000, using UO-22 for an 
example:  
1. write the frequency before the pass to 435.130 MHz (command mode)
2. launch MSPE when scheduled by WISP (KISS mode)
3. read the calculated downlink frequency and use a serial or parallel port 
output to pulse the DOWN button on the mic jack to keep up with the 
Doppler-corrected frequency.

I know it sounds old-fashioned.  It's probably easier to just use an external 
TNC.  The TS-2000 will work UO-22 out of the box, but it requires manual 
intervention.  I get fully automated operation by using Uni-Trac to control 
the antennas and the rig frequency and an MFJ-1270 TNC connected thru the 
ACC2 port.  Maybe the TS-2005 will have a full-duplex TNC and separate serial 
outputs :-)
