I am one of the [few] guys who would prefer to use the new
N8VB *vSOUND* interface and *independent digi programs*. I
believe that MixW and HRD and others have perfected their
interface and CODEC in ways that would be hard to improve
upon. I also use MixW LOGGING as my main electronic log. I
have developed some [simple minded] perl scripts to
extract log data and publish it to the web
(http://www.n9vv.com/log.html) and I would hate to lose
that functionality. I believe that IC-7800 owners who have
PSK and RTTY built-in, find that the lack of sophisticated
logging makes it just a bell/whistle and not a practical
mode to integrate into the rig. I can't imagine building
all that into the console when it has already been done so
well by so many others.
My IC-746pro has a DIGITAL mode for SSB that narrows the
filters, changed the tuning to 1/4 step size and DISABLES
THE MIC. I believe it also offsets the IF SHIFT for
European or US tones (low or high tones) on RTTY. That
capability would be welcome in the console for sure.

I've been considering doing just that for PSK. It's fairly east to enable
the existing PSK (or RTTY) mode buttons on the console and then use their
click event to set the radio up to whatever you want. Main reason I want to
do it is because I keep forgetting to run the power down when I start PSK31.
The only problem from a third-party standpoint is whether or not they
support a corresponding mode button in their software. Not a problem for
HRD or DXLab since they have been super cooperative in matching the SDR1K
interface, but you might have to manually switch the SDR console for some of
the others.

Subject: [Flexradio] Power fluxuations on 1.4.3 RTTY modes
It took me a while, but I've tracked something down.
When I run any RTTY mode under 1.4.3, power output levels fluxuate in a
way they don't in 1.4.1.
When I set the power level in 1.4.1, and transmit, the wattage is what
it has been since I started doing RTTY (about a month or two back is all).
If I set PWR where I get 25 watts on a given band, that's where it
transmits.
On 1.4.3, however, power level fluxuates, especially (it superficially
appears) when space characters are transmitted. Or, maybe it's not
space characters. But, the output can drop to near zero. I've had
several cases where it kind of hangs out a half power or two thirds.
The wattmeter on my MFJ, always reliable in the past, shows the
fluxuation as does the SDR power output indications.
There is, by contrast, little or no fluxuation on 1.4.1.
Now, I am making contacts, but the low power levels have probably cost
me a few. The obvious workaround is to use 1.4.1 for RTTY.
But, in terms of what was changed recently, could it be a cause? The
obvious stuff (compressor and compandor) are "off" and set to 0 dB gain
in any event.
Independent of this, I'm beginning to wonder if we need a new
"pseudo-mode" which would be "digital SSB". It would go to upper side
band, but it would set the power output to a lower level and make the
other needed adjustments (like forcing the compandor and compactor to
off) that are starting to become necessary. Making that work with 3rd
party software via CAT could be a bit of a challenge, though, since one
presumes that we want the regular SSB to still respond and at least so
far, we haven't put in our own RTTY modes into the base console.
