Megacycles per second was a measure in the past. To be precise, until 1960. With the organization of the International System of Units (SI), the cycle per second was officially replaced by the "hertz"

No-brainer? Who would need to write kk (or Kk)?

Well said. Capitalization (not to mention punctuation) is going down the drain in this age of phone texting. That said... SI missed its chance to dump "k" for "K", so that capitalization is consistent

:-) Martin was prescient as he has anticipated all the problems arising from the first arrangement.

Hi Dave, Are you referring to the balun inside the dummy aerial? If yes, I have initially constructed the dummy aerial as in the top circuit (balun in between single-ended L-network & preamp) in the

Fun discussion. I once found a 31.6875nHz signal in a 50-year barometric pressure record of midnight samples. The rest was 1/f noise. Andrew VK5CV Get Outlook for

Even as a radio hobbyist, I was looking for mHz signals in the 90's. I imagine many more were, for many more decades before me. Here's something to think about, I like to toss it out there every now

44.7 microHertz = [approx.] 6.7067664^12 meters THAT'S a REALLY long wavelength. -- Phil, K0TWA

Physicist here... beware. mHz --> means millihertz,? ?10^-3 Hz MHz --> means megahertz, 10^6 Hz mc? ?--> means nothing... only mc/s, i.e. megacycles per second is a measure of

If the L-network is single ended - common mode for coax - the balun belongs BEFORE the network! The balun converts differential mode to common mode. That's why it is termed a "balun: Balanced (to)

Hi Mike, Thanks for correcting my mistaken assumption. I was thinking that the imbalance can increase 2nd harmonic generation (IP2), which in turn also increases IP3 because the latter also depends on

Always wondered what about R1 and R2 being replaced by separate current sources? Simple FET ones or Full Wilson with matching transistors (THAT Corp sells chip with 4 matched HF transistors) Would be

Imbalance between top and bottom sections affects IP2 (which I don't see in the measurements), and not so much IP3. Otherwise, very good and thorough work. 73, Mike AF7KR

mhz? I mean to type 188,495,559.20579 rad/s (left handed approximation) but got tired typing. Please edit the "mhz" for me and replace it with "mc". Only geologists know about "milli Hertz"

The wellgood amplifier Roland uses is a well proven Amp with noiseless transformer feedback. It is a clone of the Wellbrook ALA1530N. There is no reason to question the sensitivity and noise figure or

A couple of observations. 1.) Why is your amplifier box so high on the mast? 2.) The leads from the bottoms of the loops seem longer than necessary. I'd make them as short and straight as

Nothing is wasted. I call it learning
