- Hi Alex,
Your BPF mobo was already supported by PowerSDR-IQ in 'direct' lets
say mode via LPT (CMOS) lines or the HSUSB interface via CY7C68013A
port (LVTTL) lines regardless of VFO and interface used.
PowerSDR-IQ can work with BCD multiplexing like it is in your mobo or
in Tony's BPF from version 1.12.06 in any line/filter/band combination
(configurable) regarding also band edges. :-)

- Hi Christos,
Great! Thanks for the info. The Mobo v3.5 is in Beta now and this
will give the builders more options to do the band switching :-)
- Hmm. I lost all email from Yahoo Groups from 5:34 PM last evening (DST)
till 5:09 AM today. Maybe it was nothing you did?
