The Nems-Clarke 1510A: another rare receiver

Nems-Clarke 1510-A

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

The amazing streak of rare radios, never before seen on Ebay or rarely seen there, continues, with the appearance of this Nems-Clarke 1510A receiver.

I attempted to find this radio in the Osterman guide to no avail — it’s not in there, unless I missed it. There are a few informational pages about Nems Clarke on the Internet (see below):

Hammarlund HQ series: A digital display modification

HQ-DisplayMany thanks to SWLing Post reader, Jeff (KB7AIL), who shares the following:

Saw the article on the DC meter in a Hammerlund HQ180.

Another mod I have seen is replacing the meter with a digital display.

It integrates with the HQ180 nicely.

They also have digi-displays in cases or use with other receivers/transceivers.

Very cool, Jeff. While I know a digital display might kill the vintage look for some enthusiasts, I have to admire such a useful modification to replace a broken Hammarlund clock/meter.

As Jeff mentions, Electronic Specialty Products has a number of external digital display boxes as well. Check out their full line of products on the ESP website. A treasure trove of central European classic receivers

Commenting on our post regarding the Kurzwellen Empfänger Siemens receiver, SWLing Post reader “13dka” writes:

Some more info (mostly about the tuning procedure) [of the Kurzwellen Empfänger Siemens] here:

BTW this site is a comprehensive source on classic shortwave radios that enjoyed some popularity in central Europe.

Indeed!  I have stumbled across many times before doing research and meant to mention it here on the SWLing Post. Thank you for the reminder!

What’s so impressive about this site is that it’s in both German and English.

If I ever make it to the excellent Friedrichshafen ham radio convention, I’ll have bookmarked on my smartphone to help me ID all of those amazing European boat anchors in the flea market!

Thanks again for the tip!

eBay Sighting: Kurzwellen Empfänger Siemens


Once again, the intrepid Dan Robinson has discovered an eBay gem. Dan notes:

From eBay Germany comes this rarely seen and apparently in beautiful condition relic:


Wow–Dan–what a beautiful receiver! It has a dial blind like my BC-348-Q, but a dial design like my Hammarlund SP-600. The best of both worlds, in my opinion.


And the green indicator lamps? Classy!






I assume, by the design, that this is a Cold War era receiver? I’m afraid I’m not at all familiar with Siemens receivers of the era.

Post readers: If you can shed light on this particular Siemens receiver, please comment!

Dan notes a unique modification on this Hammarlund HQ-180A


Many thanks to SWLing Post contributor, Dan Robinson, who shares a link to this eBay listing of a Hammarlund HQ-180A and notes:

Whoever owned this Hammarlund HQ-180A installed a DC meter where the clock or crystal unit usually is.


s-l1600 (1)

And the screws on the top of the hatch seem to indicate installation of a DC supply perhaps?

Like you, I’ve never seen this particular mod to the HQ-180A, Dan.

I’m curious if the owner installed the DC meter to replace a broken or missing clock?  Though I’ve never searched for one, I suspect those Hammarlund clocks are getting more difficult to find on the used market.

eBay find: Rack of classic receivers


Many thanks to SWLing Post contributor, Dan Robinson, who shared a link to this rack of classic cold war era receivers. The starting bid is $943.75 and there is no shipping cost as it’s local pickup only (no surprise there).

Here’s the description from eBay:

LOCAL PICK UP ONLY Paso Robles Ca. 93446. Good condition, rack of Communications and Amateur Radio receivers. Includes Hallicrafters R-46B loudspeaker, two each Hammarlund SP-600 JX-26 receivers with one frequency readout as shown above the top receiver, a National NC-300 receiver with calibrator accessory, and a Hallcrafters SX-101A receiver with calibrator accessory. The rack cabinet is included. All have normal wear for vintage electronics, worn with faded, chipped and rust spots. The SP-600 receivers (both) dial slips and may need repair. All units may need further repair, alignment, or refurbishing. Local pick up only, I can help loading into your vehicle. 70hi 22wide 20deep weights about 600 pounds

I think this would be a great deal if all of the equipment was in working order. I suspect this seller hasn’t tested anything and is, most likely, not a radio enthusiast. I bet the reason the SP-600 dials are spinning freely is because the tuning lock is engaged on each unit–possibly a good sign that the previous owner took care of the equipment.  All of it looks good (cosmetically) for its age.

If I were interested, I’d go by and check this out in person prior to bidding.

US Signal Corps: Horseback mobile

Yesterday, I stumbled upon this 1940 photograph of the US Army Signal Corps communicating via radio in the field.

I bet that radio kit weighs almost as much as or more than the typical soldier!

Does anyone know what model of Signal Corps radio that would be?


Richard comments:


The original photo is at the site below.

At the link,

It’s a Radio Set SCR-203 (Phillip pack saddle mounted). Consisted of:
BC-228 transmitter – Transmitter, 2.1-3.1 MHz, 2 ea VT-25 & VT-50, Part of SCR-203
BC-227 receiver – Receiver, 2.1-3.1 MHz, Part of SCR-203
BC-235 control box – Control box, Part of SCR-203

The unit was powered by various battery packs and a GN-35 hand cranked generator and used a 25 ft whip antenna (Image: W.J. Schweitzer collection)

Thanks so much for identifying the equipment, Richard!
