Tonight we setup a Meshtastic BBS node. This will allow you to receive messages while away from your station. Asynchronous messaging is incredibly value for off-grid communication.

INSANE Signal Strength! COMTEK 40m 4-Square Antenna from DX Engineering
Today we’re commissioning the COMTEK / DX Engineering 40m 4-Square Antenna system here at DX Commander HQ. This is one of the most powerful setups for the 40m band — insane signal strength and front-to-back ratio. In this video I’ll take you through the build, wiring, tuning, fault-finding, and finally the moment of truth… including working Japan at +20dB over S9!
If you’re interested in serious DXing or contesting on 40m, the 4-Square is a game-changer.
Thanks to:
Tim Duffy K3LR and the DX Engineering team for the Comtek
Stefano at Messi & Paoloni for the 75 ohm coax
Martin and Mike for radial work and installation help
