Video blog episode 010

Wow, it seems like just a year ago that I posted my first video!  Okay, it actually was a year ago.  This video is a how-to guide for audio processing of FM broadcast band recordings to make it easier to find and easier to hear sporadic-E and meteor scatter propagation.

Video blog episode 009

For this episode, I shot about 2 hours of video of me casually working the 20-meter band on a Saturday with a contest and two state QSO parties in progress, editing the video down to under 30 minutes.  I comment on what I’m hearing, make a few domestic QSOs, one QSO with France, and unsuccessfully work Italy.  All with 80 watts into a homebrew magnetic loop antenna.  Enjoy!

Video blog episode 007

I’m still working on the second part of the 6-meter Yagi video series, so I decided to show an example of trans-Pacific AM broadcast band reception using the RTL-SDR based AM BCB receiver detailed in Episode 006.  This was from an SDR recording on the morning of September 21st, 2016 and was a pretty good session.  Unfortunately, the audio was rather uneven because I was trying for the first time to “internally” record my laptop screen instead of shooting with the video camera.  That part worked great, but the audio didn’t go quite as well.  Still, this gives a nice flavor for what I have been able to from Arizona with the RTL-SDR based AM BCB receiver, and the Conti Superloop antenna featured in earlier videos.

Video blog episode 006

Forgot to put this up earlier, but Episode 006 of my Arizona Signal Watcher video blog is up.  This one is a brief “tour” of the RTL-SDR based receiver that I use for AM broadcast band DXing.  If you think you need to spend several hundred dollars to do well on the AM BCB, you might want to have a look.  A $20 RTL-SDR, plus a $45 upconverter, and maybe some amplification (depending on your antenna), and you may do as well as possible considering the crowding on the band and other issues.

Video blog episode 002

Episode 2 of my video blog has been posted to YouTube. This is the second video in the Superloop antenna series, and shows the construction of a decade resistance box to use as the terminating resistance of the antenna. The box allows you to repeatably set the resistance to the value you want, as opposed to trying to make fiddly adjustments of a potentiometer. This part of the project went well, other than it having a 2 ohm offset due to resistance in the thumbwheel switches, wires, and banana plug connectors. Enjoy!

Video blog debut!

Finally! My first Arizona Signal Watcher video blog episode is now available on YouTube. This is the first of a several-part series on the “Superloop” receiving antenna. This design was developed by Bruce Conti and this is my take on the design and construction. The antenna is very useful and convenient when needing a signal null in one direction and good reception in other directions, and when portability is important. The first video is entitled “Superloop Antenna Part I: Introduction” and gives an overview of the antenna design and some theory behind it. Subsequent videos will detail the construction of the antenna and the electrical/electronic components needed to optimize the antenna performance. Comments here or on the YouTube page are very much welcomed. Enjoy!
