1c7085_9394caeaaf2f4d5292d3f03fb469870amv2Are you having fun yet? Winter Field Day begins today! Participate with a club if you can, or at home if you prefer…but this is a great day to be on the air. The DARC is participating in the K5T special event station at Alford Media Services in Coppell, Texas. This is a one-day only operation; if you get the urge to join up with a club in the small hours of the morning, the Richardson Wireless Klub will be operating for the full 24 hours.

The only other contest I noticed this weekend is the CQ 160-Meter CW Contest. There’s no reason you can’t do both.

The Dallas Marathon is coming up one week from today, on Sunday, Dec. 15th. Most positions have probably been filled, but if you haven’t signed up, please head over to https://sites.google.com/site/dallasmarathoncomms/volunteering/sign-up and register.

I didn’t get a chance to try this, so for everyone’s benefit I’ll repeat this one: If you’d like to try something really different, you could get on the air using FT-8 on 2 meters! The North Texas Microwave Society is holding informal FT-8 nets on 144.174 USB each Monday at 19:30 local. Any antenna you have will be better than nothing, but a horizontal antenna is preferred.

Nothing really stands out on the contest calendar this weekend. The ARRL 160-meter contest is taking place today and tomorrow morning, and, surprisingly, the ARRL 10-meter contest will be taking place next weekend. Good luck!

If you’d like to try something really different, you could get on the air using FT-8 on 2 meters! The North Texas Microwave Society is holding informal FT-8 nets on 144.174 USB each Monday at 19:30 local. Any antenna you have will be better than nothing, but a horizontal antenna is preferred. If you have a coat hanger to spare, you can make a 2-meter dipole suitable for this net. I’m going to give it a try.

The Dallas Marathon is coming up on Sunday, December 15th, and the event needs help. If you haven’t signed up, please head over to https://sites.google.com/site/dallasmarathoncomms/volunteering/sign-up and register. The Marathon is a great event to participate in if you’ve just gained some experience at the Turkey Trot.

UPDATE from N5BB: if you’re hunting RFI like I am, you might want to follow Bill’s suggestion and listen to the sample collection provided by the ARRL.

ANOTHER UPDATE: recordings of my interference can be found here: 30 Hz, and here: 120 Hz. Careful listening and lining up the audio files in Audacity suggests to me that the interference is really always at 120 Hz, but that I was fooled by every fourth pulse being stronger than than others during some conditions. Of the ARRL samples, the light dimmer sounds most like what I’ve got.

Turkey Trot is THIS THURSDAY! Some of us have already had an early Thanksgiving dinner, so it might be easy to forget…but don’t. Set your alarm early, and bring a friend if you want to. Randy, KE5JIT, has reported that he has enough hams to fulfill the requests from the YMCA, but that walk-ins are welcome and will be put to work.

Tom, KE5ICX, is looking for a new net control for SKYNET. If you’d like to give it a try, please contact the club.

And finally, don’t forget that there is no Lecture and Lab for November, December, or January. If you weren’t there today, you didn’t miss it.

russian woodpecker hunting club Reaktor_4_29I say this every week, so here I go: the DARC is looking for volunteers to help out at the 2019 Dallas YMCA Turkey Trot! Please don’t forget to sign up—and remember that beginners are welcome.

The Dallas Marathon needs your help, too! They’ve asked that people not link directly to their information site, but if you paste this link into your address bar, it will take you right there: sites.google.com/site/dallasmarathoncomms/

The marathon staff are still short of communicators and are asking area hams to help spread the word.

The contest calendar is busy this weekend, with one big event—the ARRL Sweepstakes SSB weekendone out-of-this-world event, and one very quirky event, among many others. If you have a vacuum tube transmitter that was designed back in the roaring 20s, the AWA Bruce Kelly Memorial QSO Party is the event for you.
