I've been trying to avoid using a tuner, for the sake of ease in
bandscanning, but I'm not sure that's practical. What I might end up
doing is attaching a random wire and tuned loop to the receiver via a
switchbox. Use the random wire just to check for signals in the clear
and switch to the tuned/tunable loop to improve reception, reduce
As a photographer I've accumulated way too many tripods. I'll
probably dedicated one of 'em to a loop stand. The nearly infinitely
adjustable angles should make it handy for reorienting a loop to
minimize local noise.
