Hi Anthony,
The reason the receive in the B band is down is that is less sensitive than
the A "amateur only" receiver. I think the antenna is a good deal of the
problem with the THF6A. According to the review in QST the receive dynamic
range isn't as good as single band rigs. I think this is do to the large
bandwidth of the 6A. Did you do any experiments with other antennas?
