We started roving seriously 20+ years ago using Xvrtrs for 222, 900, 1.2 and 
2304. We used 706MKii and an IC820 which doubled as an IF for 1.2 and the 
primary for 432. We have TE Systems higher power amps for the bottom four.  
There are beams for all bands.  There are two of us in the vehicle (K9ILT 
shotgun) and our weekend gear.

The release of the TS2000X simplified life dramatically.  It became the primary 
rig for 6, 2, 432 and 1.2.  The 706 became the IF for 900 and 2304 (with an 
attenuator).  The second SO239 for HF became the IF port for 222.  The remote 
head meant that we had control of everything right in front of us.

When the Limited Rover Class was introduced we simplified further, giving up 
2304, where we had little success.  We now run the bottom four bands using the 
TS2K and our amps for VHF contests and for the UHF Contest we use the 2 meter 
output as the IF for 900.  We may go to a higher power xvrtr from DEMI for 900.

I understand the the 9100 is large and heavy, so while we were initially 
interested, the lack of a remote head kept us away.  We do have a 7300, which 
is nice for home use and are planning to pick up a 9700 for home use as well.  
With the TS2K being discontinued we may pick up a spare if the close out price 
is attractive enough.

The Kenwood resides in the Rovermobile where we use it one in a while for 
portable ops on HF.  I prefer the performance of transverters but sometimes, 
the complexity of cables and power connections increases the ceiling of 
complexity to the point where the fun gets diminished.
