Any thoughts as to tuning it or not tuning it with a capacitor? Would tuning result in any better S/N ratio? I have a preamp and have had problems in the past with tuned loops changing with age/weather/spiders etc but could do the varactor thing.

For an example of varactor tuning, see:

You shouldn't need a preamp with this loop.
