I think we can It seems to me that this band is primed and ready for an influx of hams. High-gain antennas are cheap/plentiful (mesh dishes abound). For a transceiver, the ADALM-PLUTO can easily be had for $150. SDR-console added support for receive/transmit and i have two observations about that: transmit audio is really good. receiver sensitivity seems good. L-com global has a 15dbi gain parabolic for $52.25. ADALM-PLUTO is $150. Add a cheap rotator for $? or possibly build. We need filters. Homebrew preferred, right? Can pipe-cap filters work at 2.4ghz? Is there something better? Needs moar powah. 20w on the cheap from sg lab. there are probably others out there. Thanks to the popularity of qo-100 around the world, a lot of equipment is being developed for 2.4ghz. The US and canada may not be able to use qo-100, but we could certainly help push the band into prominence in our own back yards.
