Best compliments to all those who snagged 'em. 73 de Al, W5IZ I suppose this calls into play the "spotlight" propagation mode for 160 - many around me heard them, often strong, and only twice was I a
I have a similar question regarding LOTS of metal at the base of the antenna connected to the ground radials.. In my case I have several large tower sections in a neat pile, several connected togethe
Re the questionable (or inaccurate) claim recited about using low VF coax to shorten radials in some of W6SAI's books - Orr doesn't actually state that as fact but rather reports it as what other's h
Interesting observations -- Saturday evening here in NNJ with a modest station and full Flag antenna to the NE, in an optimum position with optimum installation details, the band sounded like 20 mete
Tuesday at 1930z -- two and a half hours before my sundown -- I was copying EA3JE CQing on 1830 kHz, peaking 569. The signal stayed in for 15-20 minutes with solid copy I noticed the same here in NNJ
Downtilting UHF antennas is a common practice in cellular but is the concept practical on topband with a Pennant? I was converting a Flag to a point fed Pennant yesterday - installed on a hill with t
Can anyone comment on the advisability of powering-up a remote DC (24v) relay - about 200 ft away with a single wire with the other side simply the ground? It would be a dedicated supply not connecte
I have noticed a lot less antenna vandals when I keep the wires on my own property .. whenever the antenna maker at W2PM expands his horizons and goes into the neighbors property the "vandals" seem t
The remedy is to use a foolproof design -- The binocular core types are as close to this as you can get, and they work as well or better than toroid-wound transformers. 73, Gary K9AY The transformer
I already sent a reply to Steve that this situation sounds odd, however. His transmitting antenna should definity have TONS more noise in that environment than the AY loop whether it's vertical or ho
In a break with discussion of RMs and whether split frequency is a PC idea this is a report on band condx last night. During 0413Z to 0719 Z I worked 32 different stations in 16 different countries l
If the problem is fundementally a very strong and very local noise source, which is about the norm for QTH's like this, and there is no feed system problems, the only option would be to use a noise n
Because of a sudden appearance of a line noise I had to get out my MFJ-1026 and set it up to cancel the RF intrusion while I wait for the power company to replace the defective street light in a subd
Conditions in AZ have been very good lately! I worked my first 100w EU QSO with Marko OH3XR and a bit later W7RV did the same! This shows it is possible with lower power to DXCC from the west. I don'
2.) The sense antennas would have to be close to each noise source if the noise arrived from different directional angles. Each sense antenna would be required to NOT hear any noise from other noise
How should I lay out my radials ? Robert - one idea is to use the 100m lengths to make 2 radials more efficiently than 2 independently .. I've done that here. Run the radial from the antenna to end p
It was a great JA morning, with the first QSO in the log at 1119z and a total of 22 JA by 1218z, just after our sunrise. Many signals were S9, and band conditions were very quiet. The broadside phase
I have had some success using this device for cancelling noise, but often run into a problem where I run out of phase adjustment. If I change the noise antenna, I don't get enough noise signal. On W8
Interesting observations, Jose. Beverages are reputed not to work over highly conductive ground, but sounds like that wasn't your problem. I wonder if anyone has studied how beverages play over I hav
Btw, type 73 material is conductive, so you need to sleeve the core or use wire with a thicker insulation than enamal. If you are happy to use twice the number of turns, then consider using 284300020
