* IF A 2.8 KHZ FILTER IS INSTALLED, SSB "NORM" BW is 2.8 kHz
(was fixed at 2.7 kHz).
Can this be extended to CW and Data? It appears that "NORM" is
currently fixed at 400 Hz regardless of mode and filter. 500 Hz
would be more appropriate for CW with the 500 Hz crystal filter
and even wider values might be appropriate for some DATA A modes
with a 1000 Hz or 1.8 KHz filter.
Added to the list -- thanks.
* AUTO-SPOT (SPOT with CWT ON) now works with both very
weak and very strong signals.
Auto-spot consistently tunes to a tone 50 Hz low (50 Hz below
the value set for pitch).
I can't duplicate this. I tried various sidetone pitches and found that
auto-spot got to within a few Hz every time. What sidetone pitch are
you using? I suppose some kind of band noise could interfere with the
operation of CWT as well.
* SSB TRANSMIT BANDPASS EXTENDED AT LOW END. Improvement
is about 2 dB at 300 Hz, 3 dB at 200 Hz, and 6 dB at 100 Hz.
Can this be made optional? Excess LF response only wastes
power at low frequencies and occupies excess bandwidth.
We could add a menu entry for this -- it's on the list. Meanwhile, the
low end is rolled off a bit in hardware, too, so in practice I don't
think you'll have any problems with this.
Additional improvement possible via TX EQ.
Will TX EQ be made mode and/or input dependent? Setting TX EQ
for voice screws up the audio response for digital mode (AFSK A
and DATA A) operation. The same is true for RX EQ.
I believe both RX and TX EQ are bypassed in DATA modes. If not, they
should be. I'll mention this to Lyle.
Per-mode settings are on the list, too.
tnx
