Hey, why not arm the locals with 222 MHz too? There hasn't been any microwave activity in this immediate area except for me and the occasional rover that comes through. I've actually been working on
You probably could've worked him with a few milliwatts and a wet noodle! I've made QSO's on 903 and 1296 over 150 miles with 3 watts and a single looper. That looks like just plain refusing to work y
I never had that consideration. I always tried with whatever I had. In one of my first VHF QSO parties I put a 4 element homebrew 144 MHz yagi on a tripod in my second-floor apartment, ran about 5 wa
I'm not sure where you're going with this. Are you talking about converting handwritten logs into Cabrillo format directly? When Cabrillo first came out and after I got over the frustration of having
Well, knock me down with a soda straw! I just got a certificate in the mail today from ARRL - "Single Op - Low Power Central Division - 2002 ARRL August UHF Contest - Winner 903 and 1296 MHz" I made
AFAIK we still have 902 in the USA. But for some reason parts of the country use 902 and parts use 903. The 903 frequency seems to be popular here in the Midwest. Bill, it was 10 years ago (Dayton 19
You might want to look into the Linear Technology LT1074 IC. If you don't need more than 5 amps, these devices are great. I've designed power supplies to put out 5, 12 and 16 volts at 5 amps with the
We NEED more activity on the higher bands! And it often is a lot more work to get a QSO there than on 144 or 432 MHz. I think the extra points are worth it and will encourage more activity up there.
When was the VHF contest with the HUGE opening in the Midwest? It was a January VHF Sweepstakes and was one of the years 1976-79 but I forget which exactly. I always keep hoping that will happen agai
I remember that one, and I'm kicking myself for not having some sort of alerting system to let me know about it. The big opening I'm thinking of was one of two years we had a big multi-op effort in V
I've been interested in this and what its ramifications are for some time. I haven't seen any data at all on what frequencies and power levels are going to be used. I could see the devices the size o
If you know the DC voltage your laptop runs on (what the power supply puts out), and if it's more than 12 volts, you might consider building the DC-DC inverter circuit at: http://www.ham-radio.com/wa
It seems that the routine procedure has always been to swing your beam a lot while listening and find the direction where the signal peaks when you hear one. It isn't always in the same direction as
My tip of the day: I color-code the ends of all my pieces of coax to the antennas with heat-shrink tubing, which I've found in at least 8 colors. It really helps as long as I can remember which color
I had trouble with the colored tape coming loose and falling off, especially in hot weather when the adhesive gets very soft. That's why I went to the heat-shrink tubing. I tried clear heat shrink ar
It is the length of the boom, rather than the number of elements, that determines the gain of the antenna. For example, I have designs I've run on Yagi Optimizer for 6, 7, 8, 10 and 12 element beams
Good point. Log periodics don't have the gain of a narrowband yagi. That gets complicated. That's a good question. The number would surely change for each band. There are other factors involved, too.
To tell the truth, I get in on these VHF+ contests mainly to make some QSO's. The bands, especially 222 and up, are generally so devoid of activity in this area that I'm just happy to hear and work s
Why don't you get some microwave gear? Zack W9SZ _______________________________________________ VHFcontesting mailing list VHFcontesting@contesting.com http://lists.contesting.com/mailman/listinfo/v
The more I think about it, the more complicated it gets. Has anyone mentioned path loss yet? Path losses skyrocket as you go up the bands. An ERP of a megawatt on 10368 MHz isn't going to do you any
