A Ham’s Night Before Christmas began as just a poem, published as text, back in 1996. Later Gary (KN4AQ) did an audio version, then a video, and last year he rebuilt the video to make it high-def. It’s easily the most-watched, most popular thing he has done!
The story is here. The text of the poem, as well as links to download the audio with music,
and no-music (can be played on ham radio) is here.
This course consist of a manual in PDF format, answers manual also in PDF format and a CD image (to be burned to a CD with your favorite CD burning software – How-to with infrarecorder for example).
If interested give this course a try, I (KC2UEZ) will give it a test and see if I am successful with it. I am what some people call a No-Code-Extra, but CW is something I have been trying to learn for a while.
This is an overview of a 500,000 Watt radio transmitter site. It’s one of the slides shared ina guided video tour of the transmitter’s hardware. The radio station — whose call sign was WLW — called itself the Nation’s Station because of its ability to reach so much of the country.
It operated at the 500 kW level starting back in the 1930?s. The technology at the time meant that there were a lot of challenges involved with transmitting at this level of power. It took 750 kW input to achieve the 500 kW output. To reach that the station had a set of AC motors in the basement generating the 4500 Amps at 33 Volts DC to heat each filament. Obviously there was a lot of heat generated at the same time. The system was water-cooled. An elaborate network of Pyrex pipes carried distilled water to and from the tubes to handle the heat dissipation.
The video tour lasts about thirty minutes. It’s just packed with interesting tidbits from the experts leading the tour so add it to your watch list for some geeky entertainment over the weekend.
Last June, the ARRL Emergency Communications Advisory Committee (ECAC) was tasked with recommending improvements to ARES® and NTS so that the amateur service can better serve the public in providing emergency communications. Specific topics included: ARES and NTS objectives and organizational structures; integration of ARES and NTS; training, certification, and credentialing; and relationships with served agencies. Chairman Dale Williams, WA8EFK, former Michigan Section Manager and new Vice Director of the Great Lakes Division, reported to the ARRL Board of Directors last month. Continue reading →
Howard (KD2ABK), provided a link to a useful browser toolbar called *HamInfoBar.
HamInfoBar will help you find ham radio related information quickly. It also help you get the latest up to date DX news, articles, cluster spots, propagation predictions, as well as quick access to ITU, Zone and several other maps. HamInfoBar works with Internet Explorer, FireFox and Chrome.
Pay attention during the installation. It will try to install other applications that you may not want.

In this episode Peter builds the NS-40 40-Meter QRP Transmitter Kit. George and Tommy visit friends and find new toys at the 2013 Capital City Hamfest. Emile talks about Ham Radio Deluxe and Automating routine tasks.
In this video Dan Vanevenhoven N9LVS gives you the basics of Radio Propagation: including Sun Spots, Solar flux, K and A factors.
Why should you be interested in propagation? Well if you want to make those DX contacts you will need to be aware of when propagation is best for conditions to your target. One way to do this is to listen. Another is to check propagation sources such as WWV mentioned above. You can also get familiar with the propagation tables presented monthly in QST and CQ magazines. These charts will tell you when to expect the best propagation on what bands and at what time for your location to other areas of the world. An excellent source is to check the DX clusters online or by packet radio. This can give you current information about DX activity that is happening right now.
