“My wonderful HRO-50T. I have replaced all tubes and now need to start on capacitors and resistors.”
What a beautiful radio, Price! Once you’ve re-capped and replaced the resistors in this girl, you’ll have a phenomenal receiver. I’m a sucker for those HRO dials! Thank you for sharing!
Post readers: If you’d like to share a photo of your boat anchor on Boat Anchor Tuesday, simply send me an email with the photo and a short description. I’ll put it in the pipeline to publish!
Yesterday, as I took a little time to curate a massive collection of photos I took at the Museum of Radio and Technology, I posted a few “boat anchor” (heavy metal vintage radio) photos and labelled them “Boat Anchor Tuesday” on Twitter and Facebook.
Much to my surprise, I received a number of comments and emails with readers asking for more Boat Anchor Tuesday pics!
So I’ve decided to make it a feature here on the SWLing Post. After all, anyone who knows me knows that I’m a massive fan of boat anchors!
Your photos on Boat Anchor Tuesday!
Please send me a photo (or a few) of your favorite boat anchor. Every Tuesday, I’ll feature a reader’s boat anchor here on the SWLing Post.
If you can, include a few sentences about the radio: how you obtained it, what you like about it or any memories. We radio nostalgic people love this stuff!
Please send photo(s) and radio blurb to my email address found on our Contact page. I only plan to post one radio per week, so these will be scheduled far ahead to post automatically.
This project was a winner in the Maker Share Mission May contest. While not strictly shortwave, of course, many of SWLing Blog readers enjoy, as I do, all things radio, and especially creative and new expressions of radio. Here is a brief excerpt from the MakerShare posting:
Vintage radios are fascinating. At one point the radio was the main method for mass communication of news and entertainment and was manufactured in a variety of styles to be prominently displayed in a home. Unfortunately, many vintage radios that have been physically preserved no longer function and it is impractical for them to be repaired. Described is the design and implementation of the Raspberry Pi Radio (RPiRadio), a device that bypasses the analog electronics of a vintage radio and digitally recreates the behavior of a vintage radio that is able to be tuned to vintage radio programming.
The whole posting may be found here, with extensive details on the building of the radio and how it was programmed for sound replicating the vintage radio era.
While I love tinkering with old radios and trying to bring them back to life, some radios are just beyond reasonable repair. This can bring old radios back to life in a way which seeks to honor their past – a very cool idea indeed!

Many thanks to SWLing Post contributor, Dan Robinson, who discovered a very rareHammarlund SP-600 JX21A on eBay. Dan writes:
Collectors of classic boatanchor gear know what has been probably the rarest of tube sets year after year, decade after decade. That set is the Hammarlund SP-600 JX21A.
While there have been numerous JX21s on eBay, there has not been, to my memory, a single JX21A appearing. This particular model was a version of the SP-600 that was produced in small quantities in the 1960’s, and according to one writeup was the only one with a product detector and switchable sidebands. According to Radiomuseum it was the last model in the SP-600 series, and was recognizable for its knobs which were different because the silkscreen information was printed directly on the front panel rather than on the edge of the knob skirts.
According to Les Locklear’s excellent history of SP-600 models, the JX21A was produced between 1969 and 1972.
Now, an ultra-rare SP-600 JX21A has appeared on eBay. Like other models in the series, this would likely require replacement of numerous capacitors and a thorough refurbishment. The seller in this case has started bidding at a very low level, but if history is any guide, a rare model like this one may indeed go for thousands of dollars when all is said and done at the end of the auction.

Amazing! Thank you for sharing, Dan! What a gorgeous set. Though the seller states it’s in need of restoration, I’m pretty sure this one will get snagged up at end of auction. I’m very curious where the final price will land.
Are there any SWLing Post readers who own an SP-600 model–or the JX21A? Please comment!
