Hi, Grant. Your original was posted to the reflector as well, and I'll let this go there as well. 3:1 current imbalance, whether scalar or not, is grotesquely large with 8 evenly spaced elevated equa
Given caveats stated below, the short answer is I'd bet with odds it wouldn't make much difference. Long answer: One of the benefits of an end-fed half-wave L on 80 meters is the hi Z feed, toleratin
"Nobody on CW" is probably answered better by few people listening and most not having implemented an automated way to pick up on CW CQ's. That's sort of built into the usual ham shack blend of FT8 a
They were all worn out from the NAQP, which included a mob and a lot of good results on 160. :>)) 73, Guy K2AV _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Refl
Hi Todd, Have a look at the calculator at https://chemandy.com/calculators/return-loss-and-mismatch-calculator.htm This calculator allows me to compute the SWR for your data points, as if the Z zero
"Guy K2AV I'm guessing you don't like rg58 because of the center conductor moving outwards??" Nope. :>)) RG58 is not RG400. That's why I don't like RG58. RG400 is what should be used for winding coax
Have to pay attention to everything he is reporting. He added a feedpoint choke per K9YC at the same time. Which may, depending on the physical connections at his feedpoint, have removed the feedline
What is missing from that discussion about a maximized use of a given investment, is whether that investment however well maximized, is in fact adequate for the particular ground characteristics and
In the US anyway, it was pretty clear to me that folks were steering clear of 1840 thru and including 1843. But contesters were operating at 1839.5 and 1839.7 and 1844. The FT8 signals did not seem
I would not repeatedly bend any coax with a solid center conductor. Which leaves RG142 for permanent routing. Jumpers to and from back of TXR and amps etc are always RG400. Windings on cores are alwa
For 160 meters dont think of a jet as a reflecting surface. Try thick wire. Particularly one in a tight turn and wings significantly vertical. 73, Guy K2AV -- Sent via Gmail Mobile on my iPhone _____
It does seem, at the moment not being entirely wrapped up in ham radio, that there certainly is the analogue of OK1YQ in just about every realm of life. I can think of a few names that I personally f
I gotta agree with Rob. An inverted L aerial wire will hear ALL the noise that is around. Mine sure does. RX antenna will help enormously if there is a place to put one that does not get the noise se
Hi Mark, Response to David farther down. Short answer: Just one relay, really. Long answer: There is a lot of misinformation about FCP's floating around out there, essentially because most don't know
Hi Wes, Thanks for posting up the Severns material. I had started looking for that, but without memory of exact words (which makes searching difficult), and without absolute certainty that Rudy was w
Hi Jerry, 65% is in the wheelhouse for DOG VF's. 400 to 600 ohms seems high. In the 12 county area around Raleigh/Durham/Chapel Hill, we measured 120 - 200 ohms resonant R. The variation you experien
Hi, Ed, You're on the right track. A "beverage" ON the ground really is NOT a beverage. For two things to be called the same genus, they need to have most everything in common. This is true of big ya
Hi Mike, et al. I have personal acquaintance and knowledge of a number of hams who have put down a BOG that was anything but straight. Some with 90 degree bends, another shaped like a Z, and less ext
Hi, Jeff, A direct strike can easily overwhelm a single ground rod, not so much because of the ground rod, but because of the resistivity of the ground that is touching it. The condition of the total
Decidedly possible. W4KAZ RBN node is 7 miles away. There is skywave contamination almost every evening with large drops. It can be increased or reduced by the choice of antenna at the RX site, but n
