The question I still have is about the parallel port card in the
computer. From reading the reflector, I notice that the modern day PCI
parallel port plug in cards are generally not " true" parallel ports.
They don't conform to all the standards.
Apparently some people using the SDR-1000 found this out while trying to
use them with it. So does the DDUtil application of the parallel port
need a "true" port that conforms to all the standards or will one of
these plug in PCI ones be sufficent to do the job we are asking?

I'm also about to interface a homebrew amp (AN762 with an
external switched

I gather from the links above that I can control the filter box
(and antenna
switching) via the paralell port and DDUtils which I already have
installed.
I had been wondering how to use it for HB amplifier switching.
Hello Brian,
Since DDUTIL uses only four of the eight available data lines of the
parallel port interface to control the amplifier band switching relays, so
you can tell DDUTIL to "talk" to the other four data lines and connect them
to a second BCD-10 interface and let it control something else.
Two remaining questions.
1 I'm using flex 1500 with (currently) amplifier switching from a slave
relay from the flexwire port ptt. Is there any need to alter
this, does it
affect so2r ampkey setup? This is also probably relavent to the OP.
I think it would work the same. After all, with the F5K, you take the amp
key signal for the amplifier from the jack on the back of the F5K, which
would be virtually the same thing as the Flexwire port.
2 Is there any way to get the PowerSDR tune button to send a signal to one
of my auto ATUs (LDG) to tune, and then to accept a signal back
from the atu
once it has found a match. I suspect it can be achieved with a macro in
DDUtils.
Usually the amp key line is routed through the ATU which decides when to
tune. Before it does so, it breaks the amp key line and routes the driver
power to the ATU, which then tunes and when tuning is complete, reconnects
the amp key line. That requires that you manually key the radio, wait for
the tuner to cycle, then unkey the radio. AFAIK, there's no way for PSDR to
"see" the tuner.
