In the middle of October 2017 I was observing the 5 GHz band during strong tropopsheric ducting propagation in Central Poland.
I logged many networks out of the line of sight and some signals exceeded 300 km, incl. Czechia. I used a MikroTik radio (RB912) with a 31dBi dual-pol dish antenna on a rotator. I sucessfully estabilished a connection at a distance of over 360 km (according to the Wigle.net database).
A detailed report with some screenshots and videos is available there:

I didn’t even know DXing on 5GHz was a thing until I saw this. Impressive stuff!
This sounds like fun. How about a free log in standard in 'TikOS for messaging when we get Mikrotik DX? Look for 100 KM or more distance by return signal time? Maybe we should set up a Facebook DX with Mikrotik page. Can we have a certificate for WAC, (Worked All Countries)? Transpacific should come first. I used to do Hawaii to San Francisco in FM. In the United States it can be a WAS (Worked All States). If ARRL can do it, why not Mikrotik?
Of maybe I can frequency shift a Mikrotik down to High Frequency, get a super narrow band mode by slowing down the clock crystal, and bounce a signal off the moon. A 6 meter dish and 100 Watt power amp might do it.
