Report from the 2017 Radio Preservation Task Force meeting

SWLing Post readers might recall that, last year, I had the distinctly great honor of presenting at the 2017 Radio Preservation Task Force meeting at the Library of Congress.

Several readers have asked me to share my experiences at the conference, so I’ll note the conference highlights here.

I attended all three days of the conference. The first day (Thursday, November 2) was held at the Woodrow Wilson Center and focused on Cold War broadcasting. It goes almost without saying that this was absolutely fascinating.  I learned a great deal. One of the day’s recurrent discussion themes, for example, focused on the keen awareness of those inside the Iron Curtain that they had been regularly subjected to propaganda.  In other words, the Cold War somehow created very discerning news listeners savvy enough to separate fact from fiction quite skillfully––an ability that many fear may (unfortunately) be eroding among today’s media audiences.  

That afternoon, SWLing Post reader, Phil Ewing, took me on an amazing tour of NPR’s new headquarters [thanks SO much, Phil!].


Later that afternoon at NPR, I attended an event celebrating NPR’s founding father and mission creator, Bill Siemering.  Bill and I co-presented at the Winter SWL Fest in 2011, and I admire him greatly both as a journalist and as an individual; I particularly enjoyed the opportunity to be at this event held in his honor.

Friday and Saturday sessions were held at the Library of Congress and were equally riveting as they covered nearly every aspect of radio preservation.

Here’s our panel just a minute before the forum began.

I was on the Digital Curation panel along with Charles Hardy (West Chester University and National Council on Public History), Jonathan Hiam (New York Public Library), Matt Karush (George Mason University and Hearing the Americas), Elena Razlogova (Concordia University) and Mark Williams (Dartmouth College and Media Ecology Project).

The discussion was dynamic, and to my pleasure, our Radio Spectrum Archive was quite the hit. The sincere interest in this project was beyond encouraging.  Indeed, after my presentation, I wasn’t able to address all of the questions from those in the audience because there were so many in line to speak to me about it; eventually the LOC had to re-arrange the room for a televised event, the 50th anniversary of the Public Broadcasting Act.

But there’s more.  And it’s a great ending to our story, which is really only a beginning: via Alex Stinson with the Wikimedia Foundation, I was introduced to the Internet Archive team last month, whom, to our profound delight, has wholeheartedly agreed to support the Radio Spectrum Archive by giving us nearly unlimited space to store our massive collection of spectrum files.

In a word?  This conference was brilliant. There simply couldn’t have been a better outcome for the Radio Spectrum Archive and I enjoyed every minute of it.

Many thanks to the entire RPTF team, especially Director, Josh Shepperd, for putting this spectacular event together.

I’ve been invited to a couple other archive conferences as a result of the RPTF meeting, and I’ll give these some consideration.  Regardless, I know this: I’ll make room in my schedule for the next RPTF conference. No way am I missing it!

And at the next conference I look forward to speaking to each one of those people with whom tight scheduling prevented my speaking at this one. After all, it’s this kind of enthusiasm that assures the Radio Spectrum Archive’s future.

Many thanks to my buddy, Bennett Kobb, who also gave me a tour of the brilliant LPFM station, WERA (96.7) in Arlington, VA–what an incredibly dynamic station and staff!

I’d also like to thank my friend Kim Elliott for generously hosting me during the multi-day event. Even modest accommodation in the DC area is very expensive–no doubt, Kim’s hospitality made the conference a reality for me. Thanks again, Kim!

The Muzen OTR: A handcrafted salute to Radio Caroline

Many thanks to SWLing Post contributor, John Harper (AE5X), who writes:

I thought you and your readers might be interested in this […] a cool little radio I learned about from the YouTube channel of a drone flyer I follow.
I like the craftsmanship:

Many thanks for sharing this, John!

I’ve actually been following the Muzen OTR for several months via Indiegogo thanks to my buddy and radio-enabler, David Korchin (K2WNW).

If the name Muzen sounds familiar, it’s likely because we featured the company last year in this post. After publishing the post, I was so interested in Muzen products, I reached out to a retailer who used to be a US distributor. Sadly, he no longer carried Muzen products, though he was a big fan.

The Muzen OTR is $69 US shipped. For an FM radio, Bluetooth, AUX-in speaker that’s handcrafted, with serious audio fidelity, in such a small size, I think it’s quite a good deal. On top of that 10% of the funding will go to Radio Caroline.

Even though I’m going through a serious down-sizing at the moment, John’s note prompted me to back this campaign, so I bit the bullet this morning and ordered a Muzen OTR. [In a sarcastic tone: “Thank’s a lot, John!”] Ha ha!

Ultralight DX: A batch of inexpensive Sony SRF-39FPs found on eBay

Many thanks to SWLing Post contributor, Vance Thompson, who writes:

Thought you might be interested to see that several SRF-39FP radios have been up on eBay recently at a fairly reasonable price.

I picked one up when they first were posted, but the price has gone down the last couple of days and even has a “make offer” option with free shipping.

Click here to view on eBay.

The description indicates that they are pre-owned by inmates at a Tennessee federal prison. As of this writing, there are 8 left.

The one I got was in pretty good shape cosmetically, all things considered, and works perfectly. Given that a brand new FP version of the SRF-39 is not likely to be seen again at $20, a used one such as this with a bit of history is not a bad deal for those of us that missed out when snagging one new was an option.

Although it makes me wonder what they are being swapped out for and if we might see an increase of these pre-owned ones coming up on eBay now.

Thanks for sharing, Vance! Twenty dollars (or possibly less through a Best Offer) is a fantastic deal, in my opinion, for the elusive SRF-39FP. Click here to read out previous posts about the SRF-39FP.  Indeed, I’m mighty tempted to drop $20 on a spare unit myself. (Thanks for enabling me, Vance!)

It appears the seller has a stellar reputation on eBay too.

A $25 upgrade for the Elecraft KX2

Many of you know I’m quite a fan of the Elecraft KX2. I take this little transceiver along almost any time I travel. Not only is it a full-featured ham radio transceiver, but it’s also an exceptional shortwave broadcast receiver.

The KX2 is a quality US-built rig (like all of Elecraft’s gear) but I’ve never been a fan of its plastic encoder knob. It lacks a finger dimple and feels cheap compared to the rest of the radio. Don’t get me wrong: the stock encoder knob gets the job done, but it’s not nearly as nice as the one on the slightly larger Elecraft KX3.

Comparing the Elecraft KX3 (top) and KX2 (bottom) at Elecraft’s Dayton Hamvention booth.

Two weeks ago, I ran into another Elecraft KX2 owner and happened to notice that his KX2 had a solid aluminium encoder knob with a finger dimple. Turns out, he purchased the knob from a ham radio operator (W1JH) in Maine who manufactures and sells this knob on eBay.

The price was $24.95 US shipped. I didn’t hesitate to place an order.

You might think $24.95 is a lot to pay for such a small item, but third party Elecraft vendors tend to charge much more for comparable items. I’ve also considered adding a heatsink to my KX3, for example, but those can total upwards of $100!

My new encoder knob arrived in only a couple of days via the USPS–installing it was a breeze.

It took me all of thirty seconds to pull the plastic knob off of the KX2 and replace it with the new aluminium one. The seller even includes an Allen wrench to secure the new knob.

The new knob is slightly larger in outer diameter, but fits the KX2 like a glove. The slightly larger size makes the finger dimple a practical addition for smooth band-scanning.

If you own an Elecraft KX2 (or the Elecraft KX1) I highly recommend this simple encoder/VFO knob upgrade!

eBay Find: Cubic Defense Applications Model 4400DF

Many thanks to SWLing Post contributor, Dan Robinson, who shares a link to this Cubic Defense Applications Model 4400DF communications receiver on eBay.

I’ve been following this listing the past few days–the seller actually launched the item with a very low starting bid.

eBay unearths so many products that I would have never known existed. This military receiver is certainly a case in point.

As the seller states, I imagine the original price tag for this receiver was hefty–likely thousands of dollars. The front panel lacks many of the controls we’d like to see on an HF radio (bandwidth, RF gain, notch, etc.), however, I imagine there are a number of functions on the backlit screen and possibly accessible via an external monitor and/or keyboard.

I’m curious: are there any SWLing Post readers out there who can comment about the performance of this receiver? Have you ever put one on the air? Please comment!

Anil’s hack: Using a smart phone battery bank to power portable receivers

Many thanks to SWLing Post contributor, Anil Raj, who writes:

I wanted to share a small but useful hack with your readers.

I use a common garden variety smartphone “Powerbank” 10,000 mAH Li Ion pack to power my Sony 7600GR which is perfectly happy with the 5V which the pack supplies. [See photo above.] I see no reason why this won’t work with other radios which require a 6V supply.

As you can imagine, the setup typically lasts for many weeks of extended daily listening and recharges in a jiffy. However, one needs to sacrifice a USB cable by soldering a DC plug at the other end. Haven’t bought AA batteries in a long time…

Thank you, Anil! What a simple but useful hack. The best part is, battery packs/banks are  very inexpensive these days and, I for one, have a number of USB cables I could sacrifice for the job!
