Hello Mike.  What you want to do is key the sequencer and then use it to key 
everything else including the IF transceiver.  The order you want to key in 
is Toshiba PA, DEMI transverter then the ft726r last.  Adding a preamp is no 
big deal.  You just make it the first device you key then the Toshiba PA, 
etc.  I can't make any comments on the setup of your DEMI sequencer, how to 
key the Toshiba PA, etc. since I haven't seen any of it.  Bob and I have 
used the DEMI sequencer, transverters, etc. extensively with the microwave 
and 432 setups at W4NH.  Feel free to contact Bob and I directly for advice, 
help, etc.  We would love to get you on 3456 and work you in June and/or 
September.  Bob, do you have any other comments?
