HF preselector performance
Posted: Sat Oct 27, 2018 7:14 am
I have to be careful how I word this to try to avoid misunderstanding, but here goes...
Does the use of an HF preselector when radio reception is worse than usual increase the preselector's normal DB loss above it's norm?
Put a differnet way - If under normal reception conditions this loss is only a couple of DB, would one expect that in worsened reception conditions the loss could be in the order of 20 DB above that received without the preselector?
