SEKARC CW Night !!

If you missed the first CW Night for SEKARC, then be sure and listen next week. And even better, feel free to jump in! I used Ham Radio Deluxe to decode some of it. Machine decoding of a human generated CW signal is not good at all. I did catch some of it. If you would like to see what I captured go to the YouTube page for the video and check the info section.

The video below is my recorded audio from the event. Recorded using Ham Radio Deluxe. It will give you an idea of the pace and it will give you a chance to decode it with your ears! I did not include the text here so you could give it a shot yourself!

Thanks go out to Jack WDØCFH for running it, and Joe WØMQY for participating! Hopefully anyone that wants can jump in and give it a try! Let us know if you have any questions!

SW Randon Wire vs Beverage Antenna

I thought this might be an interesting comparison for our use in SDR receiving...... what a difference !!

Published on Jan 3, 2015

This video is a comparison of a 64ft random wire antenna and a 240ft beverage antenna. I used my classic Hallicrafters S-20R Sky Champion Shortwave receiver. You can clearly hear the difference in the noise floor and with the beverage you can hear a couple more stations. I knew the beverage was great for my Yaesu FT-101, but it rocks for SWL as well.

YL 33: The First Female Ham Radio Operators

...and their Awesome Legacy

by Ashley Hennefer

I found this great article about some of the early women amateur radio operators. Very interesting stories and details. You can find the entire article here TheMarySue.com but below is the intro...

...Female hams are called “YLs,” which is short for “Young Lady,” regardless of the operator’s age. While that seems simultaneously antiquated, cute, and patronizing, keep in mind that the ham radio subset of men is referred to as “OMs,” or “Old Man.”

300 Foot Tower Demo

This video is the demolition of a 300′ cable head end tower in Jackson, MN. Built in 1953, it did not want to fall over. Great view, and I love the sound of the fall and then the dogs barking....

NEW YEAR for SEKARC - 2015 !!

Happy New Year... Welcome to 2015 !!

2015 should be a great year for the SEKARC as we have plans for many new activities and better meeting content with our new meeting facility and it will be exciting. Here is a summary of some of the thoughts we have on our agenda for 2015.

The first item on our list is a local CW practice night. Many in the club and the SEK area are learning CW or need a brush up so David NØWKZ suggested a local CW net or similar weekly activity. At the coffee QSO Jack WDØCFH mentioned maybe not an organized net but maybe an hour set aside each week for local CW practice sessions. Look for info on these to be announced very soon! Any suggestions for a night and time?

To begin with, the January meeting on 1/31/15 will feature the Salvation Army Team Emergency Radio Network ( SATERN ) communication vehicle from Kansas City.  We will get a look around the truck and discuss what SATERN does and how we can get involved. Here is a link to the national webpage SATERN.

March, or the the first sign of warm Wednesday weather we will head to a park after the Coffee QSO for some field work! This is always fun and this year we will be trying new locations for our Wed park days so stay tuned for that.

Vintage Phillips Radio

His is an interesting video. The making of a vintage radio Philips (Tesla) T535A Sirius. The video was made in Czechoslovakia (1936) and is not in English but still interesting.
