Vote: Support the production of a car shortwave radio

SWLing Post contributor, Fred Studenberg, recently contacted me about an ingenious car (mobile) shortwave radio he’s designed. Though originally designed for his own personal use, Fred’s now considering initiating a production run of the radio for the commercial market. To do so, however, he needs funding to help pay for parts, and this is where we can help:  by voting for his shortwave car radio design in this contest–! Fred writes with details about his radio:

I wanted a high performance shortwave receiver in my car without the clutter of a separate unit under the dash.  It had to be easy to tune stations and not require any modifications to my car’s built-in radio and audio system.   I looked everywhere, and there was nothing that even came close to meeting my requirements.

Being a retired RF communications engineer, I set about designing a high performance digital radio.  It installs remotely in the trunk or hatchback area and broadcasts tuned shortwave audio to your car FM radio.  No modifications at all to the car radio or FM system are required.  It is powered right off your car’s power plug.

Operation is simple: tune your car FM radio to 88.1 or 88.3 and use a small handheld wireless key fob controller to scan through the 100 preset channels.  You have access to full shortwave band coverage in 5 KHz tuning steps with excellent sensitivity and selectivity.  There is even a digital noise blanker to eliminate spark plug ignition interference.   You can also manually scan to find new stations to add to preset memory, quick tune to WWV for time checks, and even switch the audio bandwidth for voice or music.

If your FM radio has RDS display you can see the tuned shortwave frequency as well as a digital “S” meter.  If your car radio does not have RDS, it still works.  Just press the scan button on the wireless controller until you hear something interesting or go into manual mode and scan the various shortwave bands listening for something of interest.

This started as a project just for my use, but after I showed it to a few people, I was encouraged to make it commercially available.   I’ve entered it in a design contest that will provide $10,000 worth of parts to help launch a production run.

You can see full information on the radio at www.carshortwaveradio.com and there is a link right at the top to take one to the voting site, or go directly to the voting site at Your IoT and look for the car shortwave radio entry.

If readers are interested in seeing this in production, indicate your interest by voting.  You have to vote by logging in with your Facebook account, which presumes you have a FB account–if not, they are easy to set up, and you can use a pseudonym and leave out all the personal info they ask [for] at signup.

I voted for Fred’s design earlier today. It does require using your Facebook login to vote, but the contest site can only read the public profile you choose to provide, and–if you allow it–your email address.

If you have a Facebook account, please consider helping Fred out by voting for his shortwave car radio design!

Buying a BMW in South Africa? Shortwave radio is an option!

bwm-swSWLing Post reader, Bob, has a relative who works for BMW in the United States. Recently, Bob learned that some models of BMWs shipped to South Africa have a shortwave radio option.  He followed up with this photo of the radio display [see above].

Wow, what a fab idea! Not only would I love to have a factory-installed shortwave radio in my car, but I must admit that I love the simple design of this digital radio dial: elegant, clean, and just a tad retro and sci-fi, all at once.

Now if I could simply afford the BMW…Sigh!
