Hi Don:

I ran a remote rig from 2010 to 2011.
I ran it with a Yaesu FT-450. I had a netbook running HRD here in my 
apartment, connected to 1 of the remote rig sets, you get 2 in a 
pair. I had an  external speaker, desk mic and CW paddles connected 
to it and it worked just fine.
At the remote site, I had the radio controler connected to my FT-450, 
a LAN connection and a Carolina Windom at 45 feet. You will need an 
no-ip or in my case I used dyns DNS, which now you have to pay monthly for.
On the apartment side, my setup again was connected to the LAN and 
there are 2 pages you have to administer to configure everything. Its 
pretty easy to do and the team at remote rig are pretty helpful.
I don't see any problems with configuring for kenwood, just a couple 
of jumper settings, which you would find in the manual. Mine worked 
out of the box for the FT-450.
I'd highly recommend going remote for restricted hams if you could 
access a site to remote too.
I traded mine because my dream transceiver came available and wanted 
to jump on it.
If you got any more questions, you can post to the list or email me directly.

HTH and 73:
