* * *
MCU 2.19 / DSP 1.87, 7-22-08
* AGC: Slope is now approximately linear in dB. Threshold
moved about 10 dB lower, closely matching earlier DSP revisions.
* USER INTERFACE: Minor clean-up of menu entry text and parameters,
help text, error messages, etc., to make operation more intuitive.
* SUB RX ON/OFF now has no effect on SPLIT, RIT, or XIT.
* SUB RX SYNTHESIZER is no longer updated when sub RX is turned off,
even with VFOs linked. This prevents an audio artifact when tuning.
Also
eliminated interaction between main and sub synthesizers during T-R
switching that was causing keying artifacts at very specific
frequencies
on some bands.
* IIR DSP FILTER ON/OFF SELECTION now applies to both main and sub
receivers. (IIR filter on/off is selected by tapping the ‘7’ switch
while in the
FLx BW menu entry. IIR filters apply only to 100 Hz and narrower DSP
bandwidths. They have slightly more ringing than the default FIR
filters.)
