Some of you wanted to see the complete version, uncut, of this video in which I discuss the differences between CB and the Amateur Radio Service.  This is in response to the recent episode in which the NCIS writers missed a great opportunity to discover the vibrant reality of the current amateur radio service in the United States of America.

The previous version of the video was prematurely cut short by just over three minutes.  This version includes that ending.  I also remove some of the low-end rumblings from the vehicle.  This version should sound a little bit less annoying.  Hopefully, the quality of the video is sharper, as well.  This version was edited by Adobe Premiere CC 2017.

I appreciate the many comments, views, and shares.  Please subscribe, too!

EDIT: Please view the NEW article, in which the FULL VERSION of this video exists.

I’ve been reading some of the chatter regarding the NCIS episode in which they incorrectly portray the amateur radio service. I thought I would make a video (vlog) and express my thoughts.

I use my new headset mic to make the video. If you have a few moments, please check it out, and let me know how the mic sounds.

Of course, share your thoughts on the NCIS thing… thanks!

Yes, the video gets prematurely cut off.  The editing software on my cell phone chopped off the ending, and I did not realize it until after it posted the video.  I’ll record a follow-up video that includes the ending thoughts, but in a new vlog edition.

Cheers and 73 de NW7US

OLIVIA (Also, Olivia MFSK) is an amateur digital radioteletype mode designed by Pawel Jalocha, SP9VRC, starting in 2003, and in use by 2005. The Olivia-mode goal was to be effective even in poor propagation conditions on the high frequencies (shortwave).

OLIVIA can decode well under noise, propagational fading (QSB), interference (QRM), flutter caused by polar path propagation and even auroral conditions and sporadic-E. Olivia uses a 7-bit ASCII alphabet. There were a handful of amateur digital modes that were derived from Olivia, including RTTYM and PAX.

Outside of amateur radio two-way communication, this mode is utilized during the tests run by the VoA every weekend. See the VoA RadioGram website, VoARadiogram.net, for the schedule.

The Olivia QSO between K4SOL and NW7US using 16/500 mode settings on shortwave, 2017-AUG-06 @1410UTC

The first on-the-air tests were performed by two radio amateurs, Fred OH/DK4ZC and Les VK2DSG on the Europe-Australia path in the 20-meter amateur band. The tests proved that the protocol works well and can allow regular intercontinental radio contacts with as little as one watt RF power. Since 2005 Olivia has become a standard for digital data transfer under white noise, fading and multipath, flutter (polar path) and auroral conditions.

Voluntary channelization

Since Olivia signals can be decoded even when received signals are extremely weak, (signal to noise ratio of -14 dB), signals strong enough to be decoded are sometimes below the noise floor and therefore impossible to search for manually.

As a result, amateur radio operators have voluntarily decided upon channelization for this mode. This channelization allows even imperceptibly weak signals to be properly tuned for reception and decoding. By common convention amateur stations initiate contacts utilizing either the 16/500 or 32/1000 modes and then switch to other modes to continue the conversation. The following table lists the common center frequencies used in the amateur radio bands.

The traditional channels are now under heavy use by newer modes. Thus, this Olivia group is working on refiguring the strategy for continued use and channelization. Please join us for discussion.

Have you ever wanted to be in a movie? Or maybe on TV? Well while you can make your own movie and you could be on a TV, you probably won’t be on commercial TV. However you can be on Amateur TV.

In this episode I talk with Tom O’Hara, W6ORG. Tom has been a ham for a while and had a successful ATV business for  over 50 years!! He retired and shut his business down at the end of 2014, but that hasn’t stopped him from working with Amateur TV!

Listen to this episode to find out more about Amateur TV and about Tom:

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

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:

Morse Code – Principles and Basic Techniques (US Army Signal)
(Learn to Send Perfect Morse Code by Hand – Vintage Training Film (Ham Radio / CW))

Vintage 1944 Radio Operator Training: How to Send Morse Code (CW) by Hand

This one is a pretty cool film:
1939 Film: New Zealand Shortwave Communications; Morse code (CW)

I’ve also created a play list, and most of the videos are still online. Once and a while something changes and I have to update the list. Here is the list:

Enjoy!

Come spend some time with me in this ride-along video blog episode, the first in a series that I am doing to help you begin your journey into the amateur radio hobby. This video is an experiment in that I am trying out this format as a type of “chat” in which I share my thoughts and experiences regarding the ham radio hobby, and how you might start out exploring the hobby.

Regarding the experiment: I have tried to edit the sound to reduce the road noise. Please comment on the noise level, and how well you can hear me talking about the topic. Should I ditch the ride-along format? Comments directly on the YouTube channel are better if you leave a comment on the actual video as displayed on my YouTube channel.

What is an amateur radio repeater and how do they work?

In this video, with a non-amateur-radio viewer in mind, I chat about the very basic concepts of a repeater.  This is a vlog (video blog) entry on my video channel, and it is shot in a relaxed, “ride along with me” format. Feel free to share this short overview with those who might be interested in our hobby.  There are more of these sorts of ridealongs coming.

Thank you for watching, and for sharing…
