Another great episode. Thanks
Great episode. As soon as I got home I have been anxiously looking through the web site for Vince's audio switching notes/schematic. Any chance that is coming soon?
Hi Mark, I just updated the HRWB web site. Look in the Articles section for Vince's pics and schematic.
If you haven’t seen it yet, you can use QSOBot on the Morserino32 and have lovely QSOs with robots. You configure the WiFi peer, connect and send a qrl? It should respond with a k and then you can call CQ and start up a QSO with a virtual ham.
Hi guys! Allow me to make some comments on HRWB 130:
Just a small clarification on DC motors (2-wire brushed or 3-phase brushless) regarding a comment Mike made around 51:39 about lower voltage and "should be more torque" for the tower rotor... I offer a slight correction in mental model in the spirit of the amazing generosity your talented group provides to the community's collective lawn mowing experience.
Also, I heard the words “log periodic” mentioned, but no one picked up to comment further. Another fantastic design. While there is some trade-off when comparing to a yagi of similar size, the major benefit is broadband capability on a single feedline. Sure, the gain is not quite what you may find with a mono-band yagi, but the ability to spin the dial from 13-30MHz without the need for a tuner is nice. F/B ratio and rear/side rejection ranks well too.
