What range of MHz to expect from commonly available VVCs
My own (as in yet another) calculator for small-loop transmitting antennas functions differently from all others. Hopefully in a way you will find handy. Focus is chiefly on tuning capacitor. Because once you have either rolled, brazed, or soldered the main loop into a unit whole, there’s no easy way to change that. Also, the loop you can make however you want. Your choices of tuning capacitor, though, can be very limited. Especially if you’re wanting to use a VVC.
Thus I present for your kind consideration my own contestant in an already well-packed arena. Two things it does better than most. Firstly that, for running in a continuous loop, there is no tiresome Calculate button to continually re-click. Secondly is that I have the highest personal confidence in its predictions for loop L (μH) and Cs (pF). This because of employing ultra-modern algorithms recently authored by Robert (Bob) Weaver and David Knight, G3YNH.

There are hundreds of HVAC books available, from the legendary ASHRAE Handbook to Refrigeration and Air Conditioning by C.P. Arora. So, why should you pick up the volume by Anant Narayan? Here are the critical differentiators:
As Anant worked on the final chapters, he knew that his book needed to be more than just a dry technical guide. He wanted it to be engaging, easy to understand, and full of practical examples. He included case studies of real-world projects, highlighting common mistakes and best practices.
The book you are referring to is likely by P.N. Ananthanarayan . It is widely considered a staple resource for students and professionals in the HVAC field due to its comprehensive coverage of both theoretical and practical concepts. Core Content and Structure
started his career as a service technician in the 1940s, eventually heading large service organizations for Voltas Limited
You’ll need two things for it to run: my *.exe application itself, plus also the interpreter program on which it runs. Kind of like Java that way, except that the Java interpreter is probably pre-installed on your system. The LabVIEW run-time engine will not be.

Otherwise, Windows will issue dire warnings of an unrecognized app. Once extracted from out of its ZIP archive, however, Windows will know to pass it off to the LabVIEW Run-Time Engine instead.There are hundreds of HVAC books available, from the legendary ASHRAE Handbook to Refrigeration and Air Conditioning by C.P.

*.ods spreadsheets.*.ods spreadsheets.Because I don’t know either BASIC or Python. And my skill in Perl is quite modest; not up to anything quite this complex. Especially not when it comes to the GUI. Even the math itself is largely beyond my poor understanding. Such are my faults. In LabVIEW however, I am fairly comfortable. Thirteen years now, I have put LabVIEW to use in regular support of my job as a test engineer. So I find myself well able to at the very least faithfully instantiate example equations authored by others. So I here tip my hat to the three maestros cited above (my Aussie bush hat to Owen Duffy).
