Two Meter Propagation Anomaly — Menu

Is it me or is anyone else experiencing a constant barrage of static on 147.060? I catch it as low as 147.055 to 147.065. This has been going on for at least the half hour I’ve been in my shop. I walked out the door to see if my antenna was still standing, yup it is.…

That was one of the first messages that signaled some issues in the two meter ham band last Friday (May 21, 2021) night. The rest of this story is transcribed loosely from the Facebook thread that helped to diagnose the activities of the evening. There are a lot of nuggets in this stream to show how much remote diagnosis can be performed with just your ears, and your brain... TL:DR; There's nothing wrong with the repeater, and a propagation anomaly caused temporary havoc all over central Oklahoma, and beyond...
  • Check your setting my radio did that and I had to turn my squelch to get it to stop
  • LOL, of course that one of the first things I tried. No matter where my squelch was set it was blasting its way in. Even did the ol’ IT trick of turning it of and back on again.…
  • Noise shouldn’t be breaking thru Tone Squelch – it’s probably intentional interference (someone transmitting audio noise thru an FM transmitter with the proper Tone Squelch setting) Repeater manager just needs to shut down the repeater for a while
  • Also an opportunity for folks to start doing some fox hunting
  • I don’t think it was intentional. More of a local interference.
  • Not sure it’s related but I noticed random bursts of static on the 650 yesterday, too.
  • Elevated Kp index day before, and we had geomagnetic disturbance around the time you’d posted ~8pm (dip in magnetic field)

  • That makes sense, and might explain a similar noise on 462.650 (GMRS 19) yesterday evening. It seemed every few minutes there was a bit of static. Today it’s not there.
  • Fri evening dip.
  • Thur/Fri
  • Thur G1 hit
  • There has been lots of openings (skip) the last week or so. Our machine in Elk City has been keying up to a Stillwater machine with same pl about the last week and a half!
  • Get on 146.52 and see how far you can talk!!
  • I’ve heard of that on 146.985. The PL tone on the Delaware County repeater is 110, I think. Don’t ask me what it is on the Aeronautical Center one… I’ve forgotten.
  • This is unlikely related to the latest solar outburst because, if it were, it would be heard regardless of frequency. If it’s heard over a wide area, it’s likely being *transmitted by the repeater*. VHF RFI rarely covers a large area. If, on the other hand you grab an HT and walk a couple of blocks. If the noise vanishes it’s *definitely* local to *you* and you’d best go hunt it down and kill it. Concerning CTCSS: If *you* need to transmit one, then the repeater *receiver* must hear the proper CTCSS tone in order to open the repeater squelch and transmit (repeat) the received audio.
  • The OKC650 (GMRS UHF repeater) had random bursts of static yesterday also. I finally just shut the radio off. This evening the signal is clear and several folks are rag chewing.
  • I got a couple calls last night about this and here’s what I was able to see/hear. I wasn’t near the spectrum analyzer, we just had a talkie, a couple reports, and the Internet.
    The first observation was that a caller had reported the noise, and they stated that there was no signal present on the input frequency of 147.66 MHz.
    The second observation used the HT receiving on 147.06 at the Service Station, near campus. We heard ‘white noise’ audio on 147.06. The repeater is set for a 180-second time-out-timer. If an input signal exists for more than 3 minutes, the repeater will “Time Out”, inform the listeners, and drop the transmitter until the input signal disappears. We listened for over 3 minutes, and did not hear the repeater courtesy tone beep, or say “Repeater Time Out.” We listened for 10 minutes and did not hear the repeater ID via voice, or CWID. That ID will appear on the repeater output, as required by the FCC. So, no input signal, no timeout timer, and no IDer meant that this wasn’t coming from our local repeater.
    The third observation was to use the Broadcastify feed that we provide at That receiver is 2.5 miles from the repeater and it has a small antenna to make sure it only hears the repeater. Flipping a phone to the online feed, we don’t hear any signal received on that receiver.
    While listening, we heard an amateur radio operator finally be able to key the repeater and it provides the CW initial ID. (which means it hadn’t transmitted in the previous 10 minutes). Proper repeater operations were observed after that.
  • So, what did we learn from that?
    1. This wasn’t a very powerful signal, or it was localized, because we heard it in Norman, but not 7 miles east of Norman.
    2. This wasn’t coming from the W5NOR repeater.
    3. The transmitted signal was full of white noise, with no ‘intelligent modulation’.
  • And, what do we think it was?
    1. The great propagation research and the other comments on this stream indicate that there were some radio oddities in the air. That could have raised the noise floor triggering the local receivers and made the receiver on the repeater ‘deaf’ to incoming signals
    2. It could have been someone ‘near the campus’ that had an incorrectly set up crossbanded radio. It was not moving, as the signal was constant. Pretend that the radio was set up to transmit on 147.06, and receive on any other frequency without any signals. If that radio received enough ‘noise signal’ (from the propagation oddity) to trip the receiver, but that signal was only noise, the output of the transmitter would be the white noise heard. So, if you have a cross banding radio, please take some time to learn its operation. No CWid was received, which is required. However, since people were unable to key the 147.06 repeater, it had to be broadband noise.
  • It was on 462.650 MHz also. I picked it up on my DMR 6×2. I thought I was crazy till I re read the original post and saw the comment about having it on 440. I’d go with #1 in above, but I’m not an expert. What I learned here is not all the stuff that sounds out of place really is. I had the feeling to stay quiet, so I did. Solar activity doesn’t need a license to transmit. 🙂
  • I was hearing it also in SE OKC.
  • I was hearing it in OKC at 149th/Western, approximately 10-15 miles from the repeater site (At least using directions from Google Maps, as the crow flies maybe not more than 10 miles) So what ever it was it was strong enough to blanket many of us in the area. I did tune to internet feed and all was quiet there. Which led me to walk outside and check to see if my antenna wasn’t on the ground. Hopefully it was just an isolated incident, maybe a new HAM with an improper setup, or even an old HAM making a boo boo. (Done that myself, hehe).
    But all is well in SCARS-land at the moment.
    73 y’all!

QRZ058: Zedd Ready For Ham Holiday — Menu

This ongoing series was written by SCARS charter member SK Jack Bickham WB5TZZ / KU5B. Jack was a prolific novelist, his two most known works were turned into the movies “The Apple Dumpling Gang”, and “Bakers Hawk.” These 104 Q. R. Zedd articles were originally published in the Central Oklahoma Radio Amateurs (CORA) Newsletter, the Collector & Emitter from September 1981 through April 1990, and are hosted on the SCARS web site. We are reprinting this series to provide you with a glimpse of the past.

Originally published in the June 1986 issue of the Collector & Emitter.

The world’s premiere DXer, Q. R. Zedd, A5A, made an appearance at the town of Noble’s Rose Rock Festival early in May, and took time out from signing autographs to reveal his plans for Ham Holiday in Oklahoma City later this summer.

Zedd, whose Honor Roll Ranch is just a hoot and a holler north of Noble, said he plans to mosey around the flea market and tell the faithful a few secrets of DX and life in general.

The legendary amateur radio operator who has worked all stations on all bands was married not long ago to his long-time companion and QSL secretary, Tondelayo Schwartz, W5FPN. “Once I had activated Atlantis from underwater stations, I figured I might as well relax a while and give Tondelayo her chance for happiness,” Zedd said modestly. “Besides, the way the bands are most days at this point in the sunspot cycle, I had some spare time.”

At Ham Holiday, Zedd said, he will try to address some of the following bothersome questions concerning DX:

ONE — Why is it that most of the good stuff seems to go QRT just when you’ve found him and gotten tuned up?

TWO — How come W7PHO calls some operators “loverboy,” but never calls you that?

THREE — What weird effect of propagation lets W5LFK give some DX station a 5-9 when the same DX station is 2-2 Cat best) at your station eight, miles away?

FOUR — How do you explain it when you spend $16,000 on the best towers and beams in your quest for DX, and finally work about 35 countries, and then visit a great DXer in Shawnee or someplace and find that he’s got a busted Yagi on a rusty old windmill tower, and the rotor last rotated in 1966, and the beam is tied to, the north with a piece of clothesline, and he’s worked about 360 DX counters, including three or four last week when you couldn’t even hear the colorburst crystal in your own TV set?

FIVE — What do you do with those 99 memories in some of the newest hf rigs?

SIX — Why is it that every time you get some time off to chase DX, either the band is dead or a gopher just ate through your coax?

SEVEN — After you’ve tried to QSL a new one in the Indian Ocean or somewhere, and you’ve already guessed that your report was 5-5, 4-4, 5-4, 4-5, 3-4 and 4-3, which way should you guess next, to make the master of ceremonies think it was a good contact? Should you yell, “QSL the 5-9!” (the LFK approach), or yell, “QSL the (cough)”? Or maybe start with 5-6 and work up? Or what?

EIGHT — How come the ones you’ve already worked are always a legitimate 5-9, while the ones you still need are four S-units below the powerline racket?

NINE — By what magic does the good DX always come on just after you went QRT? Or go QRT just after you found him?

TEN — Why does the ARRL get your callsign wrong when it ‘ lists DXCC credits?

ELEVEN — Why does it take fifteen seconds to tune the linear when nothing is on and you’re just messing around, but you need five minutes to get the damned thing to dip when the pileup is just beginning to get ferocious around a rare one?

TWELVE — How come a new rig is always more fun than an old one even though you knew how to work the old one, and you always made contacts with it, and operating the new one is a little like trying to fill your own teeth?

THIRTEEN — Why do you always hear that the big bass are hitting just when something like Clipperton comes on?

FOURTEEN — What medicine will best relieve the pain after you’ve bashed your top front teeth against the metal grid on your microphone?

FIFTEEN — Why do wives complain during contest weekends? What’s wrong with making them deal with the neighbors who want to watch TV? What’s so bad aboUt having three or four guys sleeping on your kitchen table? only for a weekend.

Zedd said he’ll also do a high-speed CW demonstration. Tondelayo will bring cookies, and dance.
