Great film about a great radio manufacturer and radio set.

In 1944, this short subject film was produced by the Jam Handy Organization and sponsored by the Hallicrafters Company. It shows the construction of the SCR-299 and dramatizes its use during World War II. This is a B&W documentary presenting a look at the manufacturing and use of the (now defunct) Hallicrafters Company’s SCR-299 “mobile communications unit.” This 1944 film, produced with help from the US Army Signal Corps, and by the Hallicrafters Company, explains how, using radio gear such as this Hallicrafters shortwave radio transmitter and receiver technology, the US Forces and Allies were better equipped to win World War II.

The SCR-299 “mobile communications unit” was developed to provide long-range communications during World War II. The US Military sought improvements of range, flexibility and durability over its existing SCR-197 and SCR-597 transmitters. In 1942, Hallicrafters Standard HT-4 was selected as the SCR-299’s transmitter, known subsequently by its military designation as the BC-610. The SCR-299 was first used on November 8, 1942, during Operation TORCH involving companies of the 829th Signal Service Battalion establishing a radio net that could exchange messages between beach-landed forces and bases in Gibraltar. Despite initial problems unloading the sets from convoy ships, the SCR-299s served until the installation of permanent Army Command and Administrative Network stations. According to US Army military historians, “General Dwight Eisenhower credited the SCR-299 in his successful reorganization of the American forces and final defeat of the Nazis at Kasserine Pass.”

The SCR-299 was a “self-contained” receiving and transmitting mobile high-frequency (HF; or, shortwave) station capable of operating from 2 MHz to 8 MHz. Using conversion kits, it could operate from 1 MHz to 18 MHz. The transmitter output reached 350 watts.

The entire unit came in a K-51 truck except for Power Unit PE-95 which was in a K-52 trailer. Power could either be supplied by the Power Unit and a 12-volt storage battery or 115-volt 60-cycle AC commercial power and two spare 6-volt storage batteries. The power requirement was 2000 watts, plus 1500 watts for heater and lights.

The system could be remotely controlled up to a distance of one mile (1.6 km) using two EE-8 field telephones and W-110-B Wire kit. Remote equipment was provided for remotely keying or voice modulating the transmitter, remotely listening to the receiver, and for communicating with the operator of the station.

This old WWII military training video is still useful regarding Morse code:

[embedyt]https://www.youtube.com/watch?v=YqTn-165orw[/embedyt]

This is an antique United States Navy Training Film from 1943/1944, in which proper hand-sending of Morse code is demonstrated. The film covers some basic principles and mechanics of manual keying of the International Morse code, as used during WWII.

Amateur (Ham) radio operators find Morse code (and the ‘CW’ mode, or ‘Continuous Wave’ keying mode) very useful, even though Morse code is no longer required as part of the licensing process. Morse code is highly effective in weak-signal radio work. And, preppers love Morse code because it is the most efficient way to communicate when there is a major disaster that could wipe out the communications infrastructure.

While this military film is antique, the vintage information is timeless, as the material is applicable to Morse code, even today.

There’s more about Morse code, at my website: http://cw.hfradio.org

For additional joy, here are a few of old films regarding Morse code:

In this episode we talk about the Yaesu System Fusion DR-2X repeater, the upcoming Solar Eclipse and more.

There is some interesting new features on the DR-2X repeater over the DR-1X that came out a couple years ago, but there is also something that it doesn’t have. Some of these features, I wish that we had on our club repeater, but those features are not enough for us to go out and buy this version.

There are a lot of special event stations that are going to be on the air around August 21st this year when the full solar eclipse occurs. This is the first time since 1918 that a full solar eclipse has gone from one side of the US to the other. I unfortunately am to far south to the see the full eclipse, but I should get about a 75% one here in the DFW area.

We also talk about some other stuff, but you are going to have to check out the show notes and listen to the episode to find out what that is.

It is hard to believe that June is almost over and Independence day will be here in less that ten days! It is time for that long weekend off, where families and friends get together to have a bar-b-que and “party” together. While celebrating the day is good, celebrating the week is even better, and that is exactly what we talk about in this interview.

This special event started back in 2009 and has grown every year since. Operators from each of the original 13 colonies will be on the air from Jul 1 through Jul 7 at different times. You can be part of this special event by making contact with any or all of the 13 colony stations or the two bonus stations.

Check out the show notes and listen to the episode for more information

Do you want to get back to the original roots of Amateur Radio? Maybe you are a new ham and you have a DIY side? Maybe you just want to try something new? There are so many things that you can do with an Arduino that cost only $4 or so! Anything from a morse code keyer to a 40m QRP CW Radio and a whole lot in between. You can even do things with an Arduino that has nothing to do with amateur radio but you will find a use for.

In this episode with talk with Glen Popiel, KW5GP the author of the ARRL published books, Arduino for Ham Radio and his new book that just came out, More Arduino for Ham Radio. He is also the author of the ham mesh networking book, High Speed Multimedia for Amateur Radio.

We had a great conversation and it made me literally go to the ARRL website and buy his new Arduino book while we were recording! Check out the show notes of this episode to listen and to get more information about what we talked about. There are also links to his books that you can go to to buy one for yourself.

The biggest hamfest is over, but the biggest ham radio on the air event is quickly approaching! Yes I am talking about Field Day 2017! Back in episode 67, I had Ian on and we talked about PSK31. During that interview he mentioned that he was the Field Day Chair for his radio club, the North Fulton Amateur Radio League, so I asked him to come back and talk to us about Field Day.

We had a great conversation about what Field Day is, some general information about it, what its like to be the Field Day Chairperson and be in charge of planning the event for your club and wrap it up with things that his club does during Field Day and what goes on afterwards.

Check out the show notes of this episode for more information about things that we talk about, links that we mention and probably some that we didn’t. The show notes can be found at:

Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains and Summits On The Air (SOTA) peaks to set up amateur radio stations in an effort to communicate with other radio amateurs across the state and around the world. Well, last year we celebrated the 25^th annual event so this year it must be the 26th. We are continuing the all weekend approach on August 5 and 6. However, many mountaintop activators will hit the trail early in the morning with the goal of being off the summits by noon due to lightning safety concerns.

We still have the very cool 25 Year Anniversary t-shirts (and other great stuff) available at http://www.cafepress.com/wg0at

The 14er event includes Summits On the Air (SOTA) peaks, which add over 1700 now 1805 potential summits! If you aren’t up to climbing a 14er, there are many other summits to choose from (with a wide range of difficulty). See the W0C SOTA web page at w0c-sota.org

Radio operators who plan to activate a summit should post their intent on the ham14er Yahoo Group. To subscribe to the “ham14er” email list, visit the Yahoo groups site at http://groups.yahoo.com/group/ham14er/ . Also, be sure to check out the event information at http://www.ham14er.org It is also a great idea to post an ALERT on the SOTAwatch.org website.

Frequencies used during the event
Activity can occur on any amateur band including HF, VHF and UHF. The 2m fm band plan uses a “primary frequency and move up” approach. The 2m fm primary frequency is 147.42 MHz. At the beginning of the event, operators should try calling on 147.42 MHz. As activity increases on that frequency, move on up the band using the 30 kHz steps. Don’t just hang out on 147.42 MHz…move up! The next standard simplex frequency up from 147.42 MHz is 147.45 MHz, followed by 147.48 and 147.51 MHz. We try to stay off 146.52 MHz, the National Simplex Calling Frequency to avoid overload, but if you need to make a call there, go for it…and be brief.

Warning: Climbing mountains is inherently a dangerous activity.
Do not attempt this without proper training, equipment and preparation.
