RECEPTION

WHAT MAKES A RADIO PLAY LOWER BANDS GOOD SOMETIMES . THEN UPPER BANDS SOMETIMES .
NOT BOTH AT SAME TIME.
THANKS DENVER.

Depends on time of day or night.Propogation can make the high bands good during the day and once the sun sets the low freqs can work well.Sunspots have some affect on how the bands are as do other factors.Google shortwave propogation to see what all affects the bands.Sprman.: )

You could be having trouble with the bandswitch.It could be dirty,try cleaning it a few times .Sprman: )

Like caps sometimes, other times, not

If you want to know almost everything about the fading issue, (other than in the set itself) see

Ever listen to SW? You will find bands that are more active in the day, not the night. Then in the evening, just the opposite.

Once you know what you are hearing, you can see of it is in the radio itself, or if it is from propagation.

Thanks for the info. It was that mica cap.
