Hi Hugen, Is this your product? https://aliexpi.com/WNTK

We are very sorry, there are many countries where we have not found a more suitable logistics solution. This has led to many countries temporarily unable to deliver or need to pay too high logistics

Off topic, but posting in case any of the software/firmware gurus on this list might want to contribute. Help is needed with a software version of the DSTAR AMBE encoder/decoder (patent has

Status and enable on the HC05 aren't needed. Only Vcc, Gnd, Rx , and Tx need to be connected. And Rx and Tx are probably labeled from the perspective of the module they are on so probably need to be

Sort of.. the sine integral is zeroth order spherical Bessel, the distinction is that the usual ordinary Bessel is based on circular coordinates. So, they're similar, but not the same -see the plot

The chart of impedance varying with height above ground has been around since at least 1928 or so, first published by Carter in IEE Transactions. I’ll post the original paper, with math, when I find

The message was intended for Hugen since Magie does not respond. Yes, I know about other groups, already a member of all of them :)

The “method of images” is given in some (all?) undergraduate EM Fields texts. I distinctly rememeber that it is treated in Collin and Plonsey. In those treatments the method is treated

Thank you, Jim Lux!!! When in question, consult a good reference, not hearsay or snake oil! Kraus (undergrad) and Balanis (grad level) in any edition are golden in this respect. For an excellent

So, who drives even an end-fed half-wave (EFHW) with a 3000 or 5000 source impedance directly???!!! The center of my Smith Charts is 50-ohms, unless I normalize it to something else like 75, 300, or

Kraus Chapter 10 discusses mutual impedance and gives the plot - somewhere I'm sure, the "image theory" is developed, but not in that chapter. ARRL Antenna Book chapter 8 gives same plot (Fig 20 in

I'd disagree with this one - this is ABSOLUTELY correct, but only if "the other" side is (normally expected) 50ohm source (TX) :)
