So, can I conclude that I need about 5 W/foot as I believe we sometimes have an ice build-up of about 1"/hour. As I don't want to leave that on at all time I need to monitor the temperature AND the h
Beside Mickey's correct suggestions I want to add; contact ARRL. I am also in the middle of a similar "discussion" and it is amazing how uneducated zoning people can be. ARRL provided me with an exce
I had a volunteer helping me. Didn't cost me a penny. I believe that if we would have to continue further he might have asked. Well, I received my permit TODAY 155 days after I applied for it. It was
LM Ericsson, Sweden (the old telephone manufacturer) had a patent many years ago regarding double contacts in relays. They showed that the reliability of a relay was major increased when you had two
Obviously, if any of the contacts weld together, that's it. I know that there are problems paralleling diodes but I don't know if, and don't believe, the situation is the same for relays. If you don'
You have to treat them in order for them not to split. I am not familiar with the process. My son told me that it involves heating the bamboo up so "the sap comes out". The sap in then, according to

I want to remember that there is a possibility to get rid of the capacitor by adjusting the length of the drive element. I purchased a 4 element yagi of unknown origin at a flee market. It has a gamm

The rotor will NOT work outside as the water will leak into it. Inside, protected from rain etc. it should be OK. Hans - N2JFS --Original Message-- From: n9lah@comcast.net To: towertalk@contesting.co
Obviously you can't load the rotor as much as if it mounted "right". You will have a locking spring washer taking the load. The is not any real raceways in the RS-rotor, just a few slide/glide bearin
I want to remember something about just rocking the rod up-and-down while putting plenty of water around the rod. This will work as "water-drilling-device" and I was told that you, that way, would be
Use mono-filament for my first installation. It stretched and stretched and stretched and .... Got the picture? It never broke, though. Hans N2JFS/SM6BXX How about high strength, clear mono-filament
I think you wrote "A" instead of "C" or did you put "u" instead of "l". Au (gold) seems a little expensive for me but it will last a long time though. :-) Cu (copper) or Al (aluminum) is fine for mos
It is the square, hard pin that is the secret behind the good and reliable connection of wire wrapped connections. You will not even get a close result if you wrap a wire around a round pin. (Been th
The BIG problem with Al wires is that it is not elastic (unlike Cu). Them you connect aluminum, whatever holds them together has to provide the springiness. If you use so called barrel connectors equ
I have had "good luck" with individual protectors and consider that a better approach. I have had direct strikes twice in my house (The house was built 199 and I have a good lighting protection) and
