Hi Gordon,
Yes, the antenna will take some work.? I plan to start small (inefficient) and work my way up.? I have an Ultimate 3S that works well on 630 M with WSPR, but I'd like to try some JT-9 on 630 M.? I've ordered the QRP Labs VFO kit that uses the SI5351.? I plan to stabilize (discipline) the VFO with a GPS, like with the Ultimate 3S, so it should be very stable.? The VFO can then be used to provide the two frequencies for the converted BITX40.
Fred
