<Peter## Agreed. It appears you folks have gotten the short end of
the stick....too bad.## We increase BW by using filters wider than
normal 2.8 khz. Which is done with either wider collins mech
filters at 455 IF,or wider xtal filters for a higher IF. Or any BW
you want with xcvrs like ANAN, flex etc. In my case, I use a 6khz
collins mech filter at 455...and a 5.8 khz xtal filter at the higher
IF..on both my yasesu FT-1000-MP-MKVs. Upper + lower BW is limited on
TX with the use of external digital EQ. IE: brickwall the top end at
say 3400 hz, or 3400 hz, 4500 hz etc...and ditto with bottom end.The
MK-V will generate a SSB signal in either the yaseu digital format....
with a max tx bw of 100/200/300 - 3100 hz. Or in the analog
conventional method, using mech + xtal filters. With the wider analog
filters, I can still narrow down the RX, using the width + shift c
ontrol. I also employ a lot of external audio processing on RX...
like adding harmonics to narrower ssb signals, +some RX eq....+
downward expanders etc. ## Several of us have run hundreds of tests
using varying top end BWs... with real weak ssb signals. In every
case, the widertx BWs prevail. Flip side is.... wider TX + RX BWs
are more prone to QRM. Jim VE7RF
