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.

However, if "Sendung 1" refers to the later period—specifically the aftermath of the July 20, 1944, assassination attempt within the Lair—the audio takes on a far more sinister and historic tone. Recordings from this era captured the frantic attempts by the Nazi hierarchy to assure the public that Hitler had survived. A "Broadcast 1" from this timeline would consist of a wounded but defiant Hitler addressing the nation, a rarity as his public appearances waned. These recordings strip away the veneer of the "invincible leader," replacing it with a trembling, vengeful voice that signaled the regime's desperate final spiral.
: Sites like LiveJournal often host niche communities that share links to specific radio episodes or "Sendungs".
For "Sendung 1," the content likely focuses on the early successes or the consolidation of the Eastern Front push. It serves as a prime example of how the Nazi regime sought to control the narrative of the war in real-time, broadcasting "victory" even as the logistical reality of the Russian winter began to set in.
The Wolfsschanze radio room (Funkzentrale) was destroyed 80 years ago. Yet, the idea of its "first broadcast" endures because it symbolises a moment when encrypted military traffic blurred into the dawn of modern electronic warfare. The "Dow" fragment—whether typho, timecode, or talisman—reminds us that historical audio is fragile. Entire transmissions survive only as broken metadata, awaiting a deeper decode.
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.However, if "Sendung 1" refers to the later period—specifically the aftermath of the July 20, 1944, assassination attempt within the Lair—the audio takes on a far more sinister and historic tone.

*.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).
