Interval Signals + Radio Astronomy = Bliss

Yesterday, I spent part of the better part of the day at the Pisgah Astronomical Research Institute (PARI): a place that has begun to feel like a home away from home.

As you might imagine, radio astronomy observatories are places with very low levels of radio frequency interference. Since I had a few hours on the PARI campus to play radio, I used it as an opportunity to evaluate the CCRadio-EP Pro‘s AM/mediumwave performance.

For comparison purposes, I packed the CCRadio-EP Pro, Tecsun PL-660 and (for kicks) my Sony ICF-5500W.

Now isn’t the ICF-5500W a handsome boy?

I’ll post some of the CCRadio-EP Pro videos in my final review.

Though it was immense fun tuning through the AM broadcast band right through the gray line,  being an SWL, I eventually turned to the shortwaves. The only shortwave radio I had on hand was the amazing little Tecsun PL-660. Conditions weren’t as bad as I had expected–propagation was decent and did I mention no noise?

After tuning around a bit, I happened upon one of my favorite interval signals: that of the Voice of Turkey.

Everything around me–all that was on my mind–simply took a backseat to the simple pleasure of listening to an interval signal on a cool, foggy spring evening surrounded by the beauty of PARI’s campus and those giant radio telescopes.

Though the feeling was nearly impossible to capture, I did make a recording to share with SWLing Post friends and readers from around the world. I hope you enjoy:

Al shares vintage RAE theme

Many thanks to SWLing Post contributor, Al Quaglieri, who writes:

In the ’60s and ’70s, RAE had a really evocative theme song that opened and closed their broadcasts. For years I searched for a copy of this, even going as far as writing the station about ten years ago. They graciously obliged, sending me a recording of the LATER theme, not the one I wanted. Well, here it finally is. RAE used an edited-down version.

My clip begins with a vintage RAE open and close, and then the song! It’s an obscure composition by Argentine composer Waldo de los Rios, entitled “Sol Alegre,” from a 1957 Columbia album called “Kiss of Fire.” Hope it brings back some memories!

Thanks for this stroll down Memory Lane, Al!

Icom-ID-92AD-Shortwave

Many thanks to SWLing Post contributor, David Korchin (K2WNW), for sharing this short video demonstrating the shortwave receive capabilities of the Icom IC-92AD handheld transceiver:

Frankly, I’m quite amazed at the clarity and fidelity of the Voice of Turkey interval signal on this handheld. Goes to show that with a proper antenna, and decent conditions, wide-band handhelds can certainly be used for shortwave radio listening! It also helps that David is outdoors, away from RFI, and was located on the coast of Long Island, NY.

Post readers: Have you had good fortune SWLing with wide-band handled transceivers? Please comment!
