Funny thing is my first PC was running 3.11. When they killed XP, I jumped ship as well.

Equipment / Re: worrisome symptoms from recently repaired Ameritron
« on: June 29, 2016, 2242 UTC »
That is sound advice. For longevity, I would set it around 250W PEP to allow for some slop in your metering. Your tubes and amp will last longer. Remember, going to half power is half an S unit, and I agree, most won't notice.

Equipment / Re: worrisome symptoms from recently repaired Ameritron
« on: June 28, 2016, 2146 UTC »
These rigs were never designed for lengthy use. They skimped out on cooling, transformer capacity and tubes. I will cite this as one of the reasons this manufacturer has attained the ominous moniker of 'Ameritrash'. My suggestion is cut your PEP way back or get a better amp. In my SSB days I ran a mil spec Harris tube linear with a 3CX800 in it and could routinely get 700W PEP out of it. I suspect your amp was not built to the same standards.

Equipment / Re: Grounding coax braid on a folded dipole antenna?
« on: June 13, 2016, 0111 UTC »
You should have a balun at the feedpoint of the antenna to ensure both wings of the antenna are balanced, and see the correct load impedance. A folded dipole of the correct dimension is around 200-300 ohms balanced. A common tactic on VHF and UHF frequencies is to short one end of the element to the midpoint, and take the coaxial feed to the remaining feedpoint and the midpoint of the antenna. At this point, the impedance should be between 50-75 ohms, but the antenna may suffer some imbalance.
As for grounding, you DO NOT want strike current passing though your equipment. The only correct way to do this is to bring your coax line to a ground block that is directly tied to station ground, hopefully directly to the ground rod. This way, all high current will go directly to ground and avoid passing through your equipment, causing further damage. In radio and TV I've seen a lot of damage over the years caused by poor grounding practices.

Common sense with boats too I suppose...
I had a tom-tom once. Instead of taking me to my intended destination, it led me to (of all things) and FAA airport beacon. Into the lake the tom-tom went, and on our merry map reading way we went.
Just remember, technology is no match for stupid.

Space them 1 wavelength (10 feet at FM frequencies) and feed their outputs with identical length cables to a splitter, used in this case as a combiner. You will realize more forward gain this way, but front to back ratios will remain the same.

FM DX Loggings / Re: FM DX Antenna help!
« on: June 08, 2016, 0813 UTC »
I've never been particularly thrilled with any of the multiband antennas, it seems to me they are a poor compromise for all they try to accomplish. FM only yagis these days are almost impossible to find new, and for serious work your only real option is to build something. Not difficult, calculators and designs are all over the net, and your local hardware store should have all the raw materials you need. The rest is engineering things like insulators from plumbing parts, ect. Back in my assistant chief days, I even build some circularly polarized emergency antennas to keep my stations on the air following an antenna burnout.

I bought an 8 element Winegard beam online several years back that seems to work pretty good. With nighttime enhancement, I can usually hear out to 250 miles on sticky nights. I see it's no longer available though 
A friend of mine had two of their bigger brothers stacked on a rotor. Back in around '06 we caught 25 stations out to 2000 miles with it. What a summer that was.
You may have some luck stacking a pair of these. http://www.mcmelectronics.com/product/30-2460

North American Shortwave Pirate / Skippy Radio 6925 KHz USB 6-5-2016 ~0123-0142z
« on: June 05, 2016, 0124 UTC »
Noticed this on the fish finder while listening to Wolverine. A touch over S9 on peaks, good 3 KHz modulation.
0123z Led Zeppelins 'Ramble On'
0125 pause between cuts, some audible (and visible) 60Hz hum and harmonics of such.
0126z LZ 'Whole Lotta Love'
0132z LZ 'Kasmir' occasionally slamming to S9+10dB
0139z presumed CW ID over song. 0140z CW in the clear.
0142z Appears to have gone QRT, although I still see hum modulation. Might be time to check the house for new noise sources.
Thanks for the show!

Nice signal, peaking at +10 at 0157 with Marv Johnson's 'Move a Mountain.' The usual 4-5 KHz audio!

Sounds like box # 2 has a weak oscillator transistor, or something isn't right on the crystal loading side.
...Also something I wouldn't tackle without a scope. I've been using one for so long, I can't imagine not having one.
Good luck grasshopper!

« on: May 09, 2016, 1749 UTC »
Most likely you will only have switching trash during the day, as that's when the charge controller is doing its job. Both PWM and MPPT type controllers use switching techniques to regulate charge current and usually are not well filtered. At night, unless its an off grid system with AC output, things should be pretty quiet.
Good Luck!
