[K3] Subreceiver IF output

[Thomas Horsten]

Hi all,

I am using the K3 IF output extensively for I/Q downconversion and
panadapter display. The IF Out connector makes this very easy.

But it would think it would be very useful to have a separate I/Q stream
from the subreceiver (e.g. for monitoring a separate band, or a different
segment of the same band). I'm wondering if a mod would be possible to
allow access to the 2nd receiver IF, and if anyone has done this.

It's been done. A Google search for "krx3 if output" found:

Thanks Ian, and with complete instructions too. Now I just wonder how it
compares to the KXV3A output - I know there was a mod that made the IF
signal on the main receiver much stronger, I'm not sure if a similar one
applies to the sub as well.

For another approach look at
http://www.pvrc.org/Newsletters/jun12.pdf
and in the files section of the Yahoo  K3 user group.

This uses a small preamp from Clifton Labs to provide isolation and some
gain if
desired.
