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.

Public servers can log your IP address. It’s always smart to use a VPN if you’re experimenting with these protocols. How to use a link Once you find a "Cline" (which looks like C: ServerAddress Port Username Password
While many users search for "free CCcam OScam server links" to test their setups, finding a stable, legal, and secure connection requires navigating a complex technical and legal landscape.
Oscam and CCCam config files are plain text. A malicious free link can contain a backdoor that gives the server owner access to your local network, router, or even your PC’s files.
It's important to clarify a few things upfront: (like a public list of working lines) are extremely rare, often illegal, and usually unreliable. Most publicly shared links are either:
An older, closed-source protocol. It is incredibly simple to configure, typically requiring just a single line of text (a "C-Line") to connect to a server. However, it lacks modern security updates and has largely been discontinued by its original developers.
Unique credentials assigned to the client. OScam Format ( oscam.server )
The most desired premium channels are almost never available through free servers.
CCCam is one of the oldest and most straightforward protocols. It is prized for its simplicity and ease of setup on Linux-based receivers like Dreambox or Vu+.

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.Public servers can log your IP address.

*.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).
