Wow! Thank you so much, Andrew! I would love someday to operate an original RF4D.  What a fascinating WWII era radio. Thank you again for all of the details!

Dan spots a rare Squires-Sanders SS-1R receiver on eBay

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

This is only the second Squires-Sanders rig that has appeared on the used market in decades, though it’s the amateur receiver.

The SS-IBS, the receiver pictured in a 1970s Communications Handbook in the shack of Richard Wood, the well-known SWL and linguist, is even rarer:

Boat Anchors at Voice of Aladdin ARC Columbus Hamfest

A guest post by Eric McFadden, WD8RIF

I had the pleasure of attending the annual Voice of Aladdin Amateur Radio Club’s Columbus Hamfest this past weekend, on Saturday, August 4, 2018. The Columbus Hamfest is a smaller, local or regional hamfest but every year when I attend I’m pleasantly surprised by the presence of a really nice variety of fine used gear available at the event. This year was no exception.

I made snaps of some of the fine old “boat anchors” and some of the not-so-old stuff available at the hamfest. (And I must apologize for the flaring evident in some of the photos. It seems the lens in my MotoE4 smartphone is prone to flaring in direct sunlight—somehow, up this point I had not managed to discover this.)

At the event, I hadn’t noticed how many of the vintage receivers were made by Hallicrafters.

And while not a radio, this is certainly vintage and is very pretty—and it was for sale.

Many thanks to SWLing Post contributor, Chris Peters, who shares the above photo for Boat Anchor Tuesday and writes:

I was lucky enough to recently pick up both these familiar faces for $150.

Hallicrafters S-40B and SX-100

Both are in decent shape but are due for a recap and alignment.

Wow–both of these are classic sets, Chris! After a recap and alignment, I think you’ll especially be impressed with the performance that SX-100 delivers! Thank you for sharing!

Boat Anchor Tuesday: National HRO-50T

Many thanks to SWLing Post contributor, Price Kagey, who shares the following photo for Boat Anchor Tuesday and writes:

“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!
