I have no idea how critical the phase shift is for your design, but I'll offer a couple of caveats. Unless you have characterized your cable, you don't know Vf or Zo. Furthermore, both of these vary
In the colonies of old, "807" was a euphemism for a "bottle" of beer. If that didn't do it, an 813 was a bottle of harder stuff. Wes N7WS, displaying my age. W5XC --Original Message-- From: Topband [
If people were working and logging V63KS, they weren't really copying him. He's signing V633KS. He came up out of the noise (and the noise from the east died with the rising sun) and I worked him abo
Unless the coax is acting as a delay line, in which case the phase shift is only as predicted when the line is properly terminated, the mismatch is trivial. The radio probably isn't a good match anyw

I am familiar with Alodine. It was used by the 100s of gallons of the liquid version to passivate the aluminum in the products produced by my former employer. We also had the facilities to do this an
I second TLDetails. TLW, not so much. I think the best and quickest way to understand and observe line impedance transformations is to model it using software. Two popular programs are TLW and TLDeta
With a cloud-warmer antenna and only 500W in the bowels of southern Arizona working anywhere is problematic, but to the east is worse, even at SS. I heard a lot of Caribbean contest stations with big
I operated some S&P during the ARRL contest. I'm not a contest op but wanted to give the guys I worked some points, so I tried submitting a check log. I use DXBase for my logging program so I created
Thanks everyone who answered. I see the problem. I think what I, and probably SP7DQR, assumed is that since you tell the contest people what section you're operating from on the application, the othe
I'm an old ham but relatively new to top band. Last night from here was amazing. I heard lots of EUs and managed to work S58N for my first EU on top band. It's super tough from AZ to get by you guys
The SNR is set at the antenna. There is a persistent desire to move the selectivity closer to the antenna, however.... With modern "bullet-proof" front ends, filtering can be delayed and done at i-f.
Paul, Congratulations, well done! I'm "just" 75 years of age and 59 years a ham and became interested in topband only in the last year or so. I hope to do as well as you. All the best, Wes N7WS On 1/
I just worked K6SRZ in San Francisco @ 2355Z. Our sunset here in Tucson is at 0054Z. So I worked him approximately 1 hour before our sunset and 2 hours before his. BTW, he's a real RST 589. My antenn
What is the rf grounding system for the antenna? If it's adequate then there shouldn't be any rf on the outside of the coax. If it isn't then you're bringing part of the antenna into the shack. Ferri
Do you guys use lousy receivers for these modes? Why would the mode affect the abilities of a receiver? Wes N7WS _________________ Topband Reflector Archives - http://www.contesting.com/_topband
