It might be a good baseline when you get the board from Farhan. I can't see any other way to measure it than the alligator clips - as you learned, your mileage may vary. <br /><br />That method worked fine for tuning the BPF on the HSR....or did it? That is one of the experiments I intend to do with the receiver now that I have enjoyed listening to it. More to come on that...<br /><br /> <br /><br /><br /> Scotthttps://www.blogger.com/profile/04060208963557732890noreply@blogger.comtag:blogger.com,1999:blog-8097643730373567702.post-29391475079877098982024-02-12T18:08:56.502-08:002024-02-12T18:08:56.502-08:00Thanks for the note Bill.

Suggestion accepted!<br /><br />Several benefits: My upper range just expaanded 60Mhz !) and it is a workable/cheap but effective solution. Also, the extracted 2-3 ranges of LOW frequencies can easily be amplified using MOSFET drivers/ZVS power and other brute force means, and will be much more PURE. Additionally, I'll have the bonus of creating precise and arbitrary frequencies. There are three independent outputs, each with a different frequency. <br /><br />Off-the-wall Q - For you only:<br />Being that you are into working and using Low, Medium and High/Very High and Ultra High RF energy - have you ever done any work using your skills on either/both TESLA or LAKHOVSKY technologies that often used these and still higher frequencies?

I think you should be able run two off a single Arduino - but you would need 4 digital lines for each one. If you need three frequencies I would look at the SI5351 - it has three independent clocks and will generate signals from 2.5KHz to 200MHz. You can see an example of how to program it in my SSB Radio Control Sketch - https://github.com/kk4das/SSB_Radio_Control<br /><br />Good luck with your project,<br />Dean<br />KK4DASKK4DAShttps://www.blogger.com/profile/11139781579937189613noreply@blogger.com
