Thank you for great explanation of this systems. Hat off !

Excellent engineering Steve. Bravo!

[@PT9KK]

Your preamplifiers work like a charm, and so does the transmitter to fly under a drone. Thanks for another great work and those informative and helpful videos.

fantastic real fantastic station 73 from kb2uew

[@jameyevans29]

That’s awesome

Outstanding work . I am very curious how you tune the parasitic elements and how you determine the frequency to tune them. John Limanowski N9DNB

John, I may get that done, but in the meantime, this video I made a while ago explains the basic idea for tuning parasitic elements: kzbin.info/www/bejne/aHXGp6B9hbGXipI

Fantastic video Steve! Thanks for sharing! I have to ask. Why do you use several 0.5 uH inductors instead of one 0.5 uH, one 1 uH, one 2 uH? That would give you more combinations with fewer relays. 73 Joseph VE3GKT

[@ve6wz]

Yes, indeed that is a great option! I have done that on my 80m 2 element Yagi to tune across the band. Sometimes using cascaded (summed) inductors can be a little difficult to tune. With individual inductors its a bit easier to get each tune box to be identical.

Unhealthy amount of jealousy!

This is some really cool stuff! Thanks for sharing!
