<< If you tune an FM radio to a stereo station, there is a pilot signal at 19 kHz that is used to regenerate the carrier used for the left - right separation. At least this is true for Europe, don't
<< I asked if they were goingto put a schedule up on the outage page at there site, and they said there would be. Threre is nothing there about right now. >> Actually, there has been something about
So that's why the CFA works miracles for its inventors and merely acts like a short vertical for everyone else. We're not true enough believers in magick....
<< For simplicity's sake, let's assume that we have a phase comparator that needs a 1 Hz difference between its two inputs before it creates a DC correction signal large enough to control the VCO (no
<< I appreciate that some readers may not be au fait with vector potential and perhaps its fundamental role deserves to be lightly aired in the amateur radio journals. >> I would have to agree. Very,
Welcome, Marcus! For other readers of this list who may not be aware, Marcus' web site is familiar to many NDB DXers on this side of the pond. It contains databases of South American and other beacon
<< To me, the idea of being able to actually see ionospheric effects on skywave signals at LF, which to my knowledge have never before been characterised, is more exciting than being the first to mak
It is not just you, Alberto; qsl.net does seem to be down, hopefully just temporarily. Interestingly, qth.net is also down, although the lookup does seem to work for them. 73, John Davis
Well, I don't think we need to be surprised at this. It's not Microsoft being underhanded about cash maximization or anything. It's a step toward their (and other publishers') well-publicized goals f
<< Can you get German satellite TV over there ? If so, my understanding is that in D land TV sync is used to disseminate the official time and frequency standard, and this extends to the ZDF satellit
<< I am also having a sniff at locking to off-air TV which has Rubidium accuracy in the pulse TIMING. >> Are you able to verify the use of a rubidium source there? Hardly any TV stations here use an
<< I am a bit sceptical about the "Grab" feature of Coherent - the longer the grab length, the less random the output data seems to become, even with just noise being fed into the demodulator input.
<< ...my favorite theory for the major cause of loss resistance at the moment is that it is caused mainly by dielectric losses in the ground, where the electric field of the antenna penetrates to som
<< Now we all know what a steckdosen ham is... Could you enlighten me as to what a "view-grap engineer" is??!! >> I think that's a typo for "view-graph," and refers to someone who spends his time mak
<< I believe that the 'basic rule' with an elevated loading coil is that the current remains constant from the bottom end (feeding point) up to the coil and will drop linear from the coil toward the
<< If a sufficiently large L is raised to the top of the vertical to self resonate a practical top load, this behaves as an infinite load. Think about a series tuned circuit, at just below resonance
<< Haha! The WOM - The Write Only Memory! >> I think Johan and Jim have hit on something here. I've already implemented that type of memory in wetware (between the ears). It's not quite perfected yet
<< Is anyone currently using the QSK facility ? The combination of QSK and precise timing will cause some major changes in the programme (and some extra hours of work). I am willing to keep the QSK f
<< Using DFCW instead of QRSS will reduce the QSO time to abt. 1/3 and the required stability to 1/2 (0.02ppm). More sophisticated methods (FDK etc..) might even give better results. >> I wonder...wa
