Hank,
I have my 5000A setup for both VAC on the same computer or AFSK from
a second computer. I sometimes run by Logic 8 and MixW from my other
computer. When using AFSK without VAC I found that I need to run fairly
high levels of audio in to the mic or line input because PowerSDR does
NO preprocessing when in the DIGL mode. Be careful if you switch to LSB
because then the level will be very high. The RX and TX gain have no
effect when using DIGL without VAC. The Line in RCA input gain does
work (Audio Mixer). I feed both my mic input and AFSK input into this
line input because of my multi rig switching arrangement. I have to
bump up the gain by 20db when using DIGL AFSK without VAC.
If you are only using one computer, then I think VAC is the best
solution !!! I often use VAC, Dual channel MixW, and MultRX on the
PowerSDR. I can then copy both the DX station and the pileup. When doing
this, I TX and search the pile up using the Main RX and listen to the DX
station on the SubRX. This works better for tuning. I just click on the
pileup and fine tune using the mouse roller wheel. In my case I use a
wireless Logictech trackball. It is very very fast and easy to tune. I
have found a bug in the version I'm using(SVN 1606). When I click tune,
the SubRX jumps freq and I have to toggle MultRX on and off. This bug
may all ready be fixed on more current versions.
I also have a problem with a slight delay between MixW and PowerSDR
when using VAC. MixW trails behind PowerSDR by a few hundred msecs
causing a little problem in fine tuning. This is NOT a 1000 vs 5000
problem. I think it has something to do with my new computer and its
setup. I played around with different Sample rates to minimize this but
will need to do more experimenting
I only need to run the 5000A at 25-30 watts. If I want more power I
turn on the linear. 25 watts drives my Acom 2000A to all the power I
want.
I love PowerSDR (5000A or SDR-1000) on RTTY except for one issue.
The display freq is always set to carrier freq and not mark freq that is
customary for RTTY. I use to correct for this by setting both XIT and
RIT to -2125 but that no longer works because the RIT is reset to zero
every time I click tune. Hopefully a solution will be found when more
time is available for enhancements.

Hi folks. New Flex-5000 user, and Just getting around to setting up the
digital modes, and need to draw on some of your experiences. First, rig
is
purely awesome! Gerald and Team, well done.
I am not using VAC as my limited experience with it before the Flex is
that
it tries to take over audio in/out and overall was a pain in the butt if
you
did not use it all the time. That's not the question anyway, but I do
wonder why the close association with VAC. I have two soundcards
installed, and both receive Flex audio via a mixer (left main out)) and
the
line-out of each sound card feeds a mixer port, and audio bound for the
Flex
RCA line-in is supplied by the right channel out of the mixer. This
works
fine, and I have used it with my PRO III before in a similar manner.
I use Serial Splitter by Eltima as a one-to-many means of sharing COM
ports,
and run DXLab, MixW, HRD and Writelog. So far, I have DXLab, HRD and
MixW
working with the Flex and Kenwood 2000 CAT emulation.
When in a digital mode on the Flex, does the RX and TX Gains function
for
non-VAC input and output of audio signals? Also, on previous rigs one
always looked for no ALC movement when setting up audio levels. In the
Flex
manual I believe I saw somewhere to check ALC and to make sure 0 DB was
not
exceeded. Appreciate if someone could confirm this.
Next relates to duty-cycle and RTTY. While I am sure this is available
in
the documentation somewhere, I admit to being one of those that grabs
the
manual as a last resort, and apologize in advance. Tried to post this
to
the Forums, but had trouble uploading.
Thanks and 73,
Harold Aaron KI4MF
