MCU 1.88 / DSP 1.70

[Stewart Baker]

Wayne and Team,
Many thanks for your sterling efforts on the latest firmware.

After sorting out an upload problem the end result is a radio
which as some might say in |England "is cooking with Gas" !

I can't comment the number of changes made to modes such as AM, FM
and Data which are not my primary  interest, but the ones that
effect CW and SSB are great.

The SSB transmit performance now seems about optimal, with the
COMP and ALC working as they should. There are, however more
artifacts when using Monitor on SSB. In addition I also appreciate
the increased range of the Wattmeter HP settings.

On the receive side the DSP filter setting appear to be more
stable with band change etc, but I still have the intermittent RX
loss after TX.

All in all a great job, keep up the good work...

I noticed that the LINE IN input is less sensitive with this version. I had to increase the output at the computer end. Not a problem, but I did wonder what was wrong for a moment.

However, I'm still finding that in DATA A mode when I feed in a pure tone I'm only getting 3W when I have requested 5W out, or 7W when 10W is set. Other constant carrier modes like CW and FM do give 5W out.

We increased the resolution of the MIC and LINE IN controls, so you need
  a higher setting, in the vicinity of 3x, for the same net gain.

Please see if CONFIG:TXG VCE will compensate for the difference you are
observing between audio-based Tx output versus non-audio (CW/FSK/PSK-D)
Tx levels.
