Total:  QSOs = 1  Max Dist(km) = 56  Total Score = 56

Club: Pacific Northwest VHF Society


A 35.2 mile (57.6 km) 5.8 GHz amateur radio QSO was completed on May 1, 2021
12:18 local time using commercial off-the-shelf (COTS) WiFi hardware (parabolic
dishes) and Amateur Radio Emergency Data Network (AREDN) firmware. Full battery
power portable operation was used. 

The two nodes are normally part of the Willamette Valley Mesh Network, but were
moved and configured to ensure point-to-point operation. The Sprint and SOTA
format allowed us to test the concept of portable, battery powered, long range
microwave emergency two-way communications using AREDN.

Brett, KG7GDB was on Mount Sylvania W7O/WV-096 near Portland, OR (CN85pk). 
Mark, KE7MSU, was on Round Top W7O/NC-015 near Timber, OR (CN85hq).

The necessary exchanges were made for the Spring Microwave Sprint and SOTA
Summit-to-Summit contacts by both text on HTTP pages and VOIP using Grandstream
VoIP phones, allowing full duplex voice over the amateur part 97 5.8 GHz
frequency. We achieved 15 dB SNR and 1.8 Mbps throughput at 5 MHz channel
Transmit power used was 25 dBm (PowerBeam 400) and 28 dBm (Mikrotik LHG 5XL.
Total time for setup, aiming, and operation of each AREDN station was less than
30 minutes. 

This was the first time AREDN has been used for contesting or SOTA operations in
our Pacific NW region.
73, Brett Popovich, KG7GDB
