Remember if you run a three or four wire cage to the top of the tower it is the cage, not the tower, that does most of the radiation. This I would think makes running cable inside the tower not impor
The crank up cable certainly should provide some sort of section continuity if a cage is use on the out side of the crank up. Little, IMHO would be lost even if there was some pour connection in the
Great! Yet Another Pacific DX-pedition that comes on TB 30 minutes after my sunrise in the Eastern Caribbean. I lost even a chance for 4 new ones this season because of the operators in the Pacific D
Steve, In all due respects: Common twilight is great for 160 meter DX especially over the SSW path wherein the path hugs the Greyline. In fact there are very excellent peaks during this short window.
I just don't understand physics it seems....as how can there be that much energy savings if so much heat is produced and must be dissipated? Here in the VI when the power company increased the rates
Yes Todd it was indeed a typo. the rate here now is .47 [er KW/H! Herb _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
Mike, You would be much better off by feeding the tower with a shunt or cage feed. As K2AV so accurately pointed out...an inverted "L" supported by a metal tower is not the answer for an efficient sy
The "L" most likely has a significant amount of horizontal component. It is not a bad antenna on 160 but neither is it a great antenna. It is better than and inverted Vee most of the time but there a
Marty, You really don't need software for the configuration you described. A cage feed of your grounded tower would give you the best bandwidth over a single shunt wire. Attach three four foot one in
In 2006 Tom Rauch, W8JI mentioned the disappointment with 3/8 wave vertical antennas and Carl mention today abut how "BCB stations migrated from 5/8 wave and 1/2 wave antennas." I added to Tom's rejo

On of the topics often discussed here in the past is the importance of having good common mode rejection on unbalanced coax feeds for Beverages, EWES, and Pennants etc. Most of my Beverage feeds are
Some USN subs used to be retrofitted here in the VI and I was called to pick up some of the transmitters which required a fork lift to put the transformers on the back of a truck. The RF deck used a
George, My 80 meter CW from 05/11 at 00:21 just appeared on the on line log at 7O6T. Thanks for the update. I should be able to get 40 meters but last night they were on SSB going by numbers and QSX
Thhanks Niko for sharing your experience with me. I did not find a reason why this takes place so I ran a separate 600 foot Beverage about 50 feet away and parallel to the two wire. The single wire w
I works extremely well on 40 meters in the forward direction in fact I was using it to work 706T on 40 SSB and it completely nulled out all the rouges and KC cops on the mainland that would have othe
Relays, switches, control voltage, cable power insertions etc. are all sources of problems in some climates. With DC running into a remote box I always find zillions of ants with their unusual defect
The portion of the island where I live has been declared as the East End Marine Park and some agency of the local government DPNR has determined that using any chemicals in the ground to deter pests
Thanks Mike....This is important information as one of my expensive DX-Engineering control boxes was made totally inoperable by ant defecation. I wanted to try and repair the relay box but DX-E said
The box is cast aluminum and relatively easy to take apart. However DXE appears not to wish a schematic publish nor do I want to do battle with their attorneys as others have. I would just like to ta
