color:black'>I have a number of different preselectors. Some serial and some
parallel. It would be very cool to have a programmable user interface to
control some of this stuff. Summer is coming with high static and it would be
nice to have a tracking preselector on the receiver front end so local
broadband noise doesn't saturate the A/D. I presently use switches for control.
I'm sure we could never afford to build some of these cool mil preselectors.
Harris, Cubic, Racal and Collins made some nice ones. I was lucky to get a
couple optional preselector modules for the R3150. <o:p></o:p></span></p>
