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!

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.

We have an autumn feast of amateur radio content in this ‘13 – lucky for some’ episode of TX Factor!
Bob gets to weigh up the latest offering of digital transceivers with Gary from ML&S.
We chat about the weather with two experts who always look on the bright side. Jim Bacon and Steve Nichols explain how we can work with the prevailing conditions to maximise our chances of good DX.
And Bob realises a boyhood dream by reliving the heady days of offshore radio on the UK’s high seas.
The Show is available to watch now at www.txfactor.co.uk
We hope you enjoy this nostalgic show.
Take a front-seat view of the Sun in this 30-minute ultra-high definition movie in which NASA SDO gives us a stunning look at our nearest star.
This movie provides a 30-minute window to the Sun as seen by NASA’s Solar Dynamics Observatory (SDO), which measures the irradiance of the Sun that produces the ionosphere. SDO also measures the sources of that radiation and how they evolve.
SDO’s Atmospheric Imaging Assembly (AIA) captures a shot of the sun every 12 seconds in 10 different wavelengths. The images shown here are based on a wavelength of 171 angstroms, which is in the extreme ultraviolet range and shows solar material at around 600,000 Kelvin (about 1 million degrees F.) In this wavelength it is easy to see the sun’s 25-day rotation.
The distance between the SDO spacecraft and the sun varies over time. The image is, however, remarkably consistent and stable despite the fact that SDO orbits Earth at 6,876 mph and the Earth orbits the sun at 67,062 miles per hour.
Scientists study these images to better understand the complex electromagnetic system causing the constant movement on the sun, which can ultimately have an effect closer to Earth, too: Flares and another type of solar explosion called coronal mass ejections can sometimes disrupt technology in space. Moreover, studying our closest star is one way of learning about other stars in the galaxy. NASA’s Goddard Space Flight Center in Greenbelt, Maryland. built, operates, and manages the SDO spacecraft for NASA’s Science Mission Directorate in Washington, D.C.
Charged particles are created in our atmosphere by the intense X-rays produced by a solar flare. The solar wind, a continuous stream of plasma (charged particles), leaves the Sun and fills the solar system with charged particles and magnetic field. There are times when the Sun also releases billions of tons of plasma in what are called coronal mass ejections. When these enormous clouds of material or bright flashes of X-rays hit the Earth they change the upper atmosphere. It is changes like these that make space weather interesting.
Sit back and enjoy this half-hour 4k video of our Star! Then, share. 🙂

So when I checked my Mac yesterday for pictures from ARISSat-1′s for SSTV, I was a little disappointed I didn’t have any. I know one of the problems was that it was deployed late because of a 70cm antenna issue, but also of a dumb mistake on my part. But now I have to wait another day for a pass. But to keep track and pass the time, I have a couple mobile apps to help me.
The first one is Satellite Tracker. It’s free and it’s a pretty good app for iOS. There is a paid version that gives you maiden head info too, but being that I am a poor working Ham, I need to pinch pennies when I can. The description from iTunes says,
Track satellites as they pass over your location. This application allows you to select any number of satellites and will show the track through the sky of the next pass(es) of each over your location. Frequency information can be added so you know how to tune into the signals. The satellite information is downloaded via the internet, and the iPhone GPS can be used to automatically track your location. Options allow the display of the sun and moon locations and the angle of the iPhone/iPod Touch to indicate to guide where to point your antenna. This application is primarily intended for those who use the Amateur Radio satellites but weather and other satellites can also be tracked.
Another great app that I literally just found, like just before I was writing this, was the NASA TV app. I can now watch NASA TV as well as video on demand and see when NASA programming will be appearing on other TV networks. So this is pretty awesome that I can watch NASA TV on my lunch breaks at work. Here’s the description,
The NASA Television App brings live and on-demand TV programming to your iPhone or iPod Touch. Watch the latest NASA events unfold in real-time or select from a list of recently uploaded videos. Plan your viewing up to a week in advance with the NASA TV schedule, and check out a list of NASA-related programming on other networks.
These are the kind of apps I like. They offer a lot and at a real decent price. While FREE is obviously the best, the cost of some of these apps are well what they’re worth. So if you have an iOS device, please grab them and GO!
It’s the big news of the week for Amateur Radio. ARISSat-1 will be deployed today from the International Space Station thanks to 2 Russian Cosmonauts. The satellite will have 4 Slow Scan TV cameras as well as a CW and BPSK beacon. According to what I have read you’ll be able to pick it up with just a simple hand held and a quarter wave whip antenna. I plan on testing that statement out myself.It’ll also have on board, a cross-band linear transponder for SSB/CW work. A little something for everyone. I’m thinking the SSTV is going to be what I am shooting for. AMSAT-NA has a special page setup with more information on how to receive signals from the satellite. Below is the live feed from NASA-TV. The Sat is being deployed at 14:00 UTC.
For no apparent reason, I woke up this morning, took a shower and ate my oatmeal for breakfast. Sat down a started looking through the emails I got over night and it struck me. Why don’t I look up videos on YouTube of the Munsters. Then I remembered that Herman Munster was a Ham!So I started my search knowing full well that I may never find a clip of what I was looking for. I wanted to share the entire episode, but part 1 was missing. So I would like to share this with you. Herman Munster, W6XLR-4, super Ham Radio operator.
