[Dx4win] SO2R Question

Paul or anyone on the reflector:
I just purchased a second K3 and have it working nicely as the second rig
within DX4WIN. I like the toggle feature that allows me to shift back and
forth between the two radios.
I am thinking about purchasing the DXDoubler SO2R product from Top Ten
Devices as well as their new band decoder. I would like to use one band
decoder with both rigs since I have one feed line running out to a remote
antenna switch. Here are my questions:
1. If I select Top Ten as the band decoder within the Control tab under
preferences and use LPT1 to connect the pc to the band decoder, will DX4WIN
send BCD data for both radios to the band decoder - depending on which one I
have toggled as the active radio (using Ctrl, Shift, F12)? For example, if
radio 1 is on 20M and radio 2 is on 40M will DX4WIN send the required BCD
data depending on which one is toggled in DX4WIN? The documentation
indicated that BCD data would be sent for radio 1 but did not appear to
mention if this would also happen if a second radio was also connected like
I have it now. I would hope that BCD data is sent anytime I toggle between
the two radios.
2. My second question is about the DXDoubler and how it works with
DX4WIN. Dave at Top Ten said that DX4WIN reverses the selected radio. I
assume that what he means is that if I select Radio 1 in DX4WIN the
DXDoubler device will select Radio 2. Is this a know issue with DX4WIN and
could this be fixed in a future update? That is why I am checking. Here is
a quote from the Top Ten Devices website:
DX4WIN, like many other logging programs (eg. CT, NA, TR, WriteLog), toggles
Pin 14 on the selected LPT port when the operator changes radios. The
defacto standard is that Pin 14 is high when Radio 1 is selected. However,
DX4WIN drives Pin 14 high when Radio 2 is selected. Although there are ways
to reverse cables and the like, so that switching works properly, the LEDs
on the DXD will always be reversed. The purpose of this modification is to
rearrange the internal logic in the DXD, so that everything functions
properly, and the LEDs truly reflect the selected radio.
I will also be using the DXD with N1MM, so I would want both logging
programs to handle the radios the same way. I would not want to make the
suggested Mod to the DXD to make it work with DX4WIN if it would then make
N1MM operate in reverse. I wonder if Paul has a reason for not following
the de facto standard? I would certainly want the LEDs to indicate the
correct radio when using either program.
Does anyone on the reflector use either of these products with DX4WIN? Any
tips or suggestions would be welcome.
Thank you.
