I can receive most analog voice stations that I want, but the quality of the reception is often poor to very poor. I do not think that this is due to mand-made or natural interference. I use the same antenna for H.F. and V.H.F. with my transceiver, as I do for FUNcube, and do not have the similar problems. I would like to know what I need to do to improve the quality. Thank you for any help. Alex.
