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, thereās 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 youāre 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 LĀ (Ī¼H) and Cs (pF). This because of employing ultra-modern algorithms recently authored by Robert (Bob) Weaver and David Knight, G3YNH.

Samyung SRG-1150DN/1250DN Service Manual is divided into three primary sections that cover initial setup, detailed circuitry, and troubleshooting.

The unit is praised for its rugged construction (often IPX4 rated) and high receiver sensitivity. However, common issues include tuner lock faults, power amplifier bias drift, and LCD backlight failure. This is precisely where the service manual becomes indispensable.

A service manual is a technical guide that provides detailed information on how to repair, maintain, and troubleshoot a specific device or system. It's usually written for technicians and repair professionals but can also be useful for owners who want to perform basic maintenance or repairs on their own. A service manual typically includes:
Youāll 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.J3E (USB), H3E (AM-compatible), F1B (FSK/DSC). š Manual Content Highlights

*.ods spreadsheets.*.ods spreadsheets.Because I donāt 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).
