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.
Great video and easily understandable dialogue as always. Glad to see your 160 setup is back on the air. What are future plans for the tower? Replacement or is an upgrade in the plan?
Excellentent presentation and execution. "Hatching a plan, modelling, design, engineering, validation, build, test and then validate. Why cant the ARRL Handbook and QST present projects like this that is professional ham engineering and technical skills at its best? It sure beat s arguments on reflectors, egos, fights and nothing achieved. A good example of putting your design money where your brain and mouth can do the job with professionalism.
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
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.
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: ua-cam.com/video/2DcvmGPLdT0/v-deo.html

This is some really cool stuff! Thanks for sharing!
Excellent engineering Steve. Bravo!
Thank you for great explanation of this systems. Hat off !
fantastic real fantastic station 73 from kb2uew
Excellent work!

That’s awesome

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

Unhealthy amount of jealousy!
