While recently reviewing some recent postings RE: open wire transmission lines, I found some controversial info to which I would like to add my 2 cents worth. Particularly intersting was the claim by
I would like to hear from anyone who has had experience with a beverage over a frozen pond or shallow lake (fresh water!) during winter. Eric von Valtier K8LV ________________________________________
Clive: The best way to decide if the TX antenna is "re-transmitting" noise into the RX antenna, just try opening and shorting the TX feedline while listening to the noise on the RX antenna. Changing
The postings on this subject give the false impression that this issue is too complicated for the average person to handle himself, and suggests that those who need the correct information consult th
Recent comments on this topic finally started to focus on one of the weak links in trying to establish meaningful S-meter calibration. That is, the question of the true input Z of the RX. This is ver
As a newcomer to 160M dxing, I am near the bottom of the learning curve relative to propagation on this interesting and perplexing band. Last night I witnessed an anomaly that is maybe fairly common
When I posted the measurement data, I really had no agenda. That seems to have been supplied by all of the responses. I simply wanted to document it to avoid some hand waving that goes on. However, n
This morning there was large and noisy pileup over Kh6ZM, whose waves were arriving here in the Midwest as though the propagation gods were hand-carrying them from his antenna to mine. Judging from t
Rich: Your antenna is really a vertical (the feedline) with a horizontal section on top that some regard as 'top loading'. There is no point in running a coax up to the wire. Just feed the one-wire f
During my experiments with beverage's this winter, I found it necessary to design and build good pre-amps for them. I ended up with a design which is relatively simple to build and my friend/cohort J
In reading the comments on this subject there would appear to be a controversy, which is absolutely false, as I will show. In particular, phase and polarity are NOT the same thing, and I see no menti
Note: you can skip the following if you have had one good course in EMF theory. Otherwise, read on: Consider a small loop (e.g. length=.1lambda) oriented with its plane parallel to he incoming wave d
In the original posting by W8JI, he stated: "They (loops) are electric field dominant at distances over 1/8wl up until far field where they are no different." Ther real problem with this statement is
