LRA36 and Radio Kuching QSL Cards

Many thanks to SWLing Post contributor, Richard Schreiber, who writes:

Hi Thomas,

After reading recent SWLing Post articles on LRA36 and Radio Kuching, thought I’d send along these images of QSL cards from both stations – dating back to 1981 and 1977 respectively.

I lived in Colorado at the time and heard both Kuching, Sarawak, and Argentine Antarctica from time to time and was fortunate enough to receive QSL’s.

You’ll notice on the envelope the special postmark of the Esperanza Army Base in Argentine Antarctica. In those days the covers were often as interesting as the cards.

Thanks for sharing those QSL cards, Richard! I think this is the first time I’ve seen an LRA36 QSL from the early 80s. Those cars are to be treasured!

Richard’s 25 MHz WWV QSL

Many thanks to SWLing Post contributor, Richard Schreiber (KE7KRF), who writes:

The NIST article about WWVH was very interesting and informative.

It reminded me that lately WWV’s broadcast on 25 MHz has been received from time to time here in southern Arizona. I emailed a report and recording to NIST in late June and received a QSL (images above).

I don’t know the status of the 25 MHz frequency. In 2017 NIST was soliciting reports but I haven’t found any current details on the web.

Thanks for sharing this, Richard. I’m under the impression that the 25 MHz frequency is still in use, though I may be wrong. This is also a great reminder–many don’t realize–that WWV does issue QSL cards!

Of course, as we’ve mentioned in a previous post, if the FY2019 presidential budget proposal is accepted/approved, WWV will be no more.

Yet Another Internet Radio!

by Richard Schreiber (KE7KRF)

After deciding that an internet radio could be an important source of entertainment in our household, we formulated a few general guidelines:

  • We opted not to use an aggregator but would pick and choose stations we enjoyed and discover the URL’s ourselves. Also would be satisfied with a couple of dozen stations. Based on a recent decision to pare down the number of TV channels we were paying for, having access to hundreds of stations seemed impractical and unnecessary.
  • The price had to be affordable, thus eliminating many stand-alone, commercially available internet radios.
  • We already owned a quality portable speaker (Bose SoundLink Mini) so the internet radio didn’t need to duplicate that component.
  • Didn’t want to tie up nor be tethered to a laptop, tablet, or netbook. We predicted that would eventually lead to less and less use of the radio.

After some research, coupled with the fact I already had some experience with Raspberry Pi computers, that small device appeared to be our best choice. I had recently purchased the newer 2 B model, which has plenty of computing power, and had installed Ubuntu Linaro as the OS. (As an aside, this OS has not to my knowledge been upgraded for the latest Raspberry Pi 3). There are several other operating systems that will work just as well including the official Raspbian OS available through the Raspberry Pi Foundation.

I installed the MPD music player daemon and its client MPC, which is used to add to and delete station URL’s from the playlist, control volume, etc. An important find was the iPhone app called MPod which provides remote wireless access to the features of MPC. At the moment it is a free app for the iPhone (in my case the iPod Touch).

For portability, my Raspberry Pi is being used “headless”, meaning it is not connected to a monitor, keyboard or mouse. If maintenance is required you can use PuTTY, a SSH and telnet client, wirelessly from a Windows (or MAC?) PC, using a command-line interface. Mainly this is needed to shut down the Raspberry Pi properly before turning off the power, but it boots completely on its own when powered up. The MPod app will then load the playlist of stations and let you start playing the radio without direct access to the Raspberry Pi.

The sound output of my Raspberry Pi is connected to the auxiliary port of our Bose SoundLink Mini Bluetooth speaker. But instead of trying to implement Bluetooth on the Raspberry Pi, I took the easy way out and use a direct connection. The sound reproduction from this setup is very good, though audiophiles might be somewhat more critical.

The above represents a minimal investment if you already have a good speaker on hand. It does require some on-line research and learning at least enough to install the OS and software. The good news is that there are many websites and forums providing step-by-step instructions and helpful hobbyists willing to explain some of the more cryptic aspects. A few of the websites that I found to be helpful:

http://www.instructables.com/id/Arduino-Raspberry-Pi-Internet

http://cagewebdev.com/raspberry-pi-playing-internet-radio

https://learn.adafruit.com/raspberry-pi-radio-player-with-touchscreen

A couple of these also explain how to add a display to your Raspberry Pi internet radio.

Our Raspberry Pi radio is on each evening and has been trouble free. It is worth mentioning that this is a very portable setup, and can even be powered by a battery pack (the kind used for recharging tablets and cell phones) for a few hours. Of course you need to be near a wifi hotspot.


Thank you, Richard! What a great way to use the inexpensive Raspberry Pi. I have a spare Pi2 and an amplified speaker here at the house. Though I don’t need another WiFi radio, it would be fun putting this little system together.

Richard’s 1998 St. Helena Day QSL Card

Many thanks to SWLing Post contributor, Richard Schreiber (KE7KRF), who shares the following:

Here [above] is the QSL card I received in 2004 for the 1998 St Helena Day shortwave broadcast. There were, I recall, some staff changes and other issues that delayed many reports from being verified, but resubmitted everything in 2004 and they promptly verified.

For the 1998 broadcast I actually phoned the station in St Helena and was put on the air, but unfortunately didn’t record the broadcast.

This is one of my most prized QSLs.

Thank you, Richard. It would be one of my most prized QSLs as well! What a great memory–thank you for sharing!
