Flex is fully aware that the price of the V/U + the 5000 will limit the
sales of the V/U. For those already owning the 5000, the V/U together as
two sixty watt units with high performance and fully capable of full
duplex operation, and is CHEAPER than the same system assembled from
DEMI units. Now, you have to already have the 5000 to plug it in so it
is limited to the 5000.
The Flex equipment is fully capable of supporting external digital
programs and CAT. Both of these are supported via "virtual connections".
A pseudo sound card is set up and other programs connect to the pseudo
sound card to deliver audio to/from the radio. The same thing for CAT
control: a pseudo com port pair is set up, one at the radio and one at
the controlling program, to support control of the radio via CAT
commands. The radio has its own set of commands but implements Kenwood
commands as well.
I have the USB version of the LVB tracker and the latest model Kenpro
(5400A) with the relay control lines brought out to the plug. The LVB
plugs into that plug directly. This is good. I should have remembered
this because Brooks developed the KCT Tracker and Tuner with the
interface to Quiktrak at the beginning of our friendship. I used both to
command the Microsat's in the first days, I should have remembered and
should have realized that the plugin interface probably became a
standard when Kenpro did and Yaesu maintained it in the B model.
