I received my new 400 Hz filter midway through the WAE RTTY contest and since I
wasn't really contesting, took the time to install it.
I guess I'm a little underwhelmed so far, but to be fair I wanted to compare it
under fire with the 2.8 KHz filter I have been using. (I expected less buckshot
from out-of-the-passband adjacent signals with the narrower filter, although
this may be a commentary on the lousy transmitted signals)
I continued to allow the 2.8 KHz filter to be used on data modes because if I
decide to use the PSK modes, I might want the wider BW.
Problem is... when switching the crystal filters manually, the DSP bandwidth
defaults to 2.8 KHz when I select the 2.8 KHz crystal filter and 400 Hz when I
select the 400 Hz crystal filter, even though I may have previously reduced the
Width setting to something narrower. Likewise, when in
Data mode with the 2.8KHz filter selected, hitting "NORM" defaults to 400 Hz
BW, which again selects the 400 Hz filter.
I suppose this is by design, but why can't the radio simply maintain some
independence between the crystal and DSP filters?
