If I'm going to work people on 24, 47 and/or 78 GHz in the contests I am just about going to have to make two transverters and loan one to someone to work me. With the equipment I have planned, I'm n
Yeah, we have the ARRL UHF contest this weekend, the first weekend of the 10+ GHz contest two weeks after that, the Sept QSO Party coming up and the second weekend of the 10+ GHz contest. Lots of thi
Yeah but VHF is not HF. I figgered you'd know that by now. In some past years I've only had a dozen people to work in that one. It's not worth going out with 10 bands in the middle of winter, taking
Who's going to be within shouting distance of EN50 this weekend (besides WB8BZK and K9JK)? 73, Zack W9SZ [snip] _______________________________________________ VHFcontesting mailing list VHFcontestin
Illegitimi Non-Carborundum! Only 2 to 3% of the population is that antisocial. I'd just ignore and carry on. 73, Zack W9SZ _______________________________________________ VHFcontesting mailing list V
Yes; I don't know if it varies around the USA but in the Midwest we use 144.260 as a microwave coordination frequency. I'll probably have it along during the UHF contest. There are no rules disallowi
I started the contest from a hill in EN50rl at 00Z on Sunday (Saturday evening local) and packed everything up at 1430Z no Sunday as a big thinderstorm loomed. But for this location, conditions were
Not here! I thought it was The Big One. NEVER seen condx this good on UHF/microwave before. Guess I was in the right place at the right time this year ... finally! I'll summarize after I get some sle
For weak-signal work (CW/SSB) it's 902.100 or 903.100. Around here 903.1 is more popular but some people use 902.1. My transverter is crystalled so 144.1 = 903.1. The IF rig, however, does go down to
I've made a few quick NBFM QSO's on 10368.100. With the beam width being so narrow I doubt I was QRM'ing anyone. I doubt if a quick FM QSO on any microwave band would be a problem in the weak-signal
Sure. Depends on how much you want to put into frequency accuracy. My 902/902 transverter uses a crystal oscillator that doesn't drift at all after about a minute of warm-up and then only drifts a kH
I'm using either the KD6OZH circuit built dead-bug style or the VE1ALQ circuit along with the KD6OZH PLL circuitry for my phase-locked LO's. Both LO's work great with that PLL circuit. But yes, at 90
In this area 903 is pretty bad but not unusable from the portable site I've been using. Up north it's far worse from what I've been told; W9ZIH has given up on the band and is selling his 903 gear. 9
My mistake; W9ZIH is selling his 5760 gear as that band has also become unusable up in his area. I don't think he was ever on 903. I hadn't had my coffee yet when I sent that last! 73, Zack W9SZ ____
I'm guessing that the devices which performed well were actually noise-matched and the others weren't; perhaps they were just tuned for maximum gain? Many component manufacturers supply the gamma (op
Hi Les, Well, to simplify it, what you want from your preamp is the optimized noise figure. This represents the lowest value for noise figure you can achieve at a given frequency or small range of fr
I have had pretty good luck designing amps using the gamma(optimum) [noise match] figure when it is provided by the manufacturer along with the s-parameters. I'm usually pretty close when doing it th
MSA-0686 (Same as MAR-6): eBay item # 150174040711 MSA-1105 (same as MAV-11): eBay item # 150201615485 This seller is VERY reputable and I have bought dozens, maybe even hundreds of items from him on
I had the best conditions (and consequently the best score) I've ever had in that contest this year. I had to send in a log! 73, Zack W9SZ _______________________________________________ VHFcontestin
