Jeff, K8ND write in part. Remember, this is from 12-degrees North of the Equator, in the bright Jeff, I have similar experiences here before sunset......hear a lot and work nothing. Remember now with
Larry, he can also try 4-400A's or 4-400C's with the thoriated tungsten filament so he can turn PA voltage on at the same time. Or put in a time delay relay to allow filaments to get warm before plat
John, You don't need to put up anything since your 75 foot tower with a C-3 on top will make a much better TX antenna on 160 with a shunt fed or cage feed. There is one thing about the Force 12 C-3 i
Brian, If the pre-amp is located, I presume where the Beverage or flag, pennant, etc are located, at least a half wave away and out of the induction field of the TX antenna your pre-amp should be abl
Especially when I worked EY8MM last night and he gave me 599. His signal was the best I have ever heard him. But during the CQWWSSB I had to really struggle to get anything to the East of me. Herb, K
uired. Some have reported success with inexpensive automotive DC relays. They can handle the current but for TX voltage I haven't any idea...as it all depends on your feed/match system. Good luck, He
Gentlemen Manufacturing such noise generating devices and exporting them to the USA may violate several sections of the U.S. Code and FCC regulations. I had heard that complete embargo's of such equi
Eric, most microwave relays won't take HV that exists between an open wire in a normally resonant Marconi where reactances, current and voltages are excessive depending on the power you run and the d
Phil, You were on at 0900 this morning peaking at 449. I have been able to work ZL3IX at east with 589 both ways at this time so if the tropical static is not to high you should be able to get some r
Glad to Help Mike, Go to fcc.gov and select the media page where you can list by geographic district and frequency range all AM radio stations in the United States. Select Audio Divison Select AM Ra
Jorge, I used here the Dynair push button video switches that are used in TV stations to switch video or monitors to different 75 ohm source material. I currently have in the RX line a 12X1. Nice thi
A good source of "free" wire are discarded sections of CATV cable in the company dumpster...where you can use a pocket knife peel off the messenger cable which can be prepared as needed for the size
Pete, Yes some brands or off brands of RG-6 sucks up moisture like a sponge. They are a foam product and.with diurnal sunlight heat and night time cooling on the jacket laying out in the sun during t
Charlie remember any top loading connected that far (20') below the top reduces the over all vertical element height above that point and you will then end up with a 40' top loaded vertical rather th
Very interesting especially since all my Beverages are directly adjacent to a huge Salt Pond some terminating about 500 feet away. Under each Beverage the water table (of brackish water) is only abou
No the cage can be shorter and actually end at the 30 foot level...but you will have to check the base impedance to design the proper match. At least more than a half wave to reduce interaction espec
A 48 foot pole on 160 without any top loading will result in low feed point impedence and low efficiency even with a good silver plated loading coil. It still may be better for DX than a low dipole.
