Everyone has different needs. I personally like the bandwidth as it
stands. On 80m nets in a crowded band, the narrow bandwidth is a big
help in isolating net members from others only 2khz away. I know others
say my audio sounds "constricted" on transmit but it's not a lot
different than what many DX'ers use for maximum "punch" in a pile up,
again a big help on a net frequency on a crowded 80m band.

The filter on my ubitx seems narrow. By feeding in a 1000 hz signal
into the mic input and measuring the power output and then going up
and down in the audio frequency I seem to have about a 1650 hz to the
3 db down in output power. Only about 1800 hz or less and the power
out drops 10 db or more.
I though by now someone may have tried to broaden the filter. I have
not had time to,but hope to lower the capacitors in the filter some
to see if it helps.
The small electric microphones seem not to be all that good either
from several I tried. I switched to a Shure amplified mic and get
much better audio reports from several I talk to on an 80 meter
sched. I do feed it through an amplifier for about 150 watts to
bring the signal up to what they are used to hearing me at.

Thank you all. I like Jazz. On my mp3 player I have a 3 piece
band. Drums, bass, and piano. The drummer is playing on the snare
with brushes. I plug my SSB-Mite in it and it sounds good. When I
flip the bypass switch to filter the drummer on the snare and the
bass disappear but the piano still sounds good. . When I tried it
in my uBitx it sounded better in bypass than in filter mode. Now
I know why. I can use it on other non-filtered radios.
