Steve,
Stafford VA has 23cm DV and DD. Not sure HOW it’s used but it does exist.
Locally, KN2K / Ray and I tested our 9700 DV on 23cm simplex, my 16 el yagi at 30’ and his 11 ele yagi at 6’ (basically ground level) and had excellent results with no dropouts at 8 miles. Next test will be DD with same configuration. I expect similar results.
I agree that this band and mode are worthy of development and use. I can see in some rural areas where AREDN is not practical or achievable that sufficient tower access is accessible and distance requirements could be realized using DD on 23cm for networking and file exchanges in local EmComm situations.
