Charlie, My resolution is not as good as some people here, either. But where there's a will, there's often a way. :-) 73, Mike www.w0btu.com _________________ Topband Reflector

If it's a ham, his rig could be screwed up. Although unlikely, the same problem that causes the constant emission could cause it to switch modes or transmit a carrier on two frequencies simultaneousl
Same here. I second Guy's observation. And I regularly run the legal limit through my F connectors, and occasionally the legal limit with high SWR! Yet, they don't even feel warm to the touch afterwa
The end of the coax CCS center conductor always has sharp jagged edges. It doesn't take a rocket scientist to figure out that these can and will damage the female contacts, by removing the plating an
It certainly is not asking for trouble, Jim. It is good practice, and after using it in countless UHF, N, and F connectors for over 40 years without a problem, I agree 1000% percent with Tom. Even th
RG8X can handle more than the legal limit on 160. I think you would be better off with a ferrite core choke. Look at http://www.karinya.net/g3txq/chokes . The choke we use is described (and photo) at
I almost put a link to your info in my previous e-mail, Jim. That's where I got the info to build the choke I use. 73, Mike www.w0btu.com _________________ Topband Reflector Archives - http://www.con
Silicone dielectric compound ("grease") should not be used as a lubricant. It's actually somewhat abrasive. Hoping to extend its life, I once tried that stuff on a high-quality silver-plated rotary w
I saw that show on PBS last night. I don't recall anything in it about sprites affecting radio propagation, but it was one of the most fascinating NOVA episodes that I have ever seen. I just sat ther
I agree. Some high-speed images of that airglow fanning out and apparently actually coupling to the top of the ionosphere were quite intriguing. That part near the end about that guy monitoring the e
Anything is possible, but I know what I used and saw, Tom. It was a small squeeze tube labeled "silicone dielectric grease". I was the only person that serviced electronic equipment in that company w
Thanks for your thoughts on this. But all this tells me is that some silicone dielectric greases may not be abrasive. I am certain that some are, because I am not the only one who has experienced thi
Max, Do you remember what the brand, etc. it was? Potable here just means it's approved by the FDA for use in drinking water systems. 73, Mike www.w0btu.com _________________ Topband Reflector Archiv
Those switch contacts carried 5 VDC at a milliamp (at most!) to and from a CMOS interface IC (similar to BCD, but it wasn't) on the logic board of the computer that ran the machine. And I don't think
The Stew is the best, but let's not forget the ARRL 160 Meter contest the first weekend in December. http://www.hornucopia.com/contestcal/weeklycont.php?mode=custom&week=next#4358 73, Mike www.w0btu.
We can work meteor scatter on VHF, does comet scatter work on 160? ;-) 73, Mike www.w0btu.com _________________ Topband Reflector Archives - http://www.contesting.com/_topband
I know, it's a little late to be asking this, but does anyone have any suggestions for a free, simple logging program that will work for the ARRL 160 this weekend? It would be nice if it also worked
Thanks for all the recommendations for N1MM, but I am just unable to install it on my shack's Linux computer. Under WINE, I get a database run-time error after I do the latest update. And there's som
