Surviving a nuclear disaster: “Go in, stay in, tune in”

There are so many reasons having a reliable radio at the ready is a good idea.

We radio geeks get it.

This morning, an item from Business Insider UK appeared in my news feed. The focus of the article was what not to do after a hypothetical nuclear detonation. Researchers discovered that the knee-jerk reaction from most would be to get in their car and drive away from the affected area as quickly as possible. Turns out, this is about the worst thing you can do because vehicles are such poor insulators from deadly nuclear fallout.

Here’s what’s recommend instead, according to Brooke Buddemeier, a health physicist and radiation expert at Lawrence Livermore National Laboratory:

“Your best shot at survival after a nuclear disaster is to get into some sort of “robust structure” as quickly as possible and stay there, Buddemeier said. He’s a fan of the mantra “go in, stay in, tune in.”

“Get inside … and get to the center of that building. If you happen to have access to below-ground areas, getting below ground is great,” he said. “Stay in 12 to 24 hours.”

The reason to wait is that levels of gamma and other radiation fall off exponentially after a nuclear blast as “hot” radioisotopes decay into more stable atoms and pose less of a danger. This slowly shrinks the dangerous fallout zone — the area where high-altitude winds have dropped fission products.

(Instead of staying put, however, a recent study also suggested that moving to a stronger shelter or basement may not be a bad idea if you had ducked into a flimsy one.)

Finally, tune in.

“Try to use whatever communication tools you have,” Buddemeier said, adding that a hand-cranked radio is a good object to keep at work and home, since emergency providers would be broadcasting instructions, tracking the fallout cloud, and identifying where any safe corridors for escape could be.”

Regardless of the scenario, a preparedness kit should always include radio. Mobile phones have limited utility when the network infrastructure is disrupted or overloaded. TVs aren’t practical or portable.

Radios are a simple way of main-lining life-saving information during disasters.

But again, we radio geeks get it!

Buyer Beware: Dan shows us how to spot a scam on eBay

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

This is an example of a classic scam — and these are usually seen involving
Watkins-Johnson 8711/A receivers.

The seller puts a photo of what appears to be a good condition WJ up,
with additional photos. But often these photos are faked or taken from
other ended Ebay auctions.

The description is usually, as with this item, in blue letters noting
the item is available only for immediate sale, and not for auction,
despite the fact that the auction is — an AUCTION and has a
starting price.

I make it my business to reports items like this to eBay and eBay has
a pretty good record of recognizing scams and removes them.

I think it’s important to point out these items to SWLing readers to
help avoid people being ripped off.

No doubt!  Thank you so much for sharing this, Dan. I didn’t realize scams like this were prevalent on eBay.

I’m willing to bet this scammer’s plan is to get you to outside the boundaries of eBay’s protection as soon as possible, luring you with a believable bargain price. This is why they ask for you to message them instead of bidding.

In my opinion, eBay is one of the safest sites for online purchases, but it is certainly not void of scammers. Remember the proverb, “If it sounds too good to be true, it probably is!”

Thanks again, Dan!

DK’s Barn Find: A GE Super Radio II

My good friend, David Korchin (K2WNW), has a knack for finding diamonds in the rough.

He’s been known to find a radio that needs TLC, take it home and restore a bit of its former glory. He’s had some amazing luck in the past.

Recently, DK sent a video of of his recent acquisition: a beat-up GE Super Radio II he purchased for two dollars. This radio will win no beauty contests, but it still plays well.

Check out DK’s video:

Many thanks, DK, for allowing me to post this video. It goes to show you that you should never pass up an opportunity to adopt a Super Radio. Even if the telescopic antenna is all but missing, the internal ferrite bar is where the money is!

Play on!

Back from Xenia: My 2017 Hamvention spoils

I’m finally back from a week of travels which included the 2017 Hamvention held a the Greene County Fairgrounds in Xenia, Ohio.

As an inside exhibitor, I was quite busy at Hamvention–indeed, my voice is only now recovering.

I did manage to sneak away from our table on several occasions to visit with vendors, friends, and check out new innovations (thanks to ETOW volunteers Eric McFadden, Miles McFadden and Robert Gulley!). I also attended the NPOTA (National Parks On The Air) forum on Sunday.

This year, I posted hundreds of photos of the event here on the SWLing Post: both inside exhibits and flea market booths.

I’ve also already started a re-cap/review of the 2017 Hamvention which I plan to post in the next few days. Stay tuned.

In the meantime, though, a number of readers have asked what I brought home from the Hamvention. Though I had no intention to buy stuff this year–seriously–I did manage to come home with a few treasures.

Panasonic RF-2200

If you’ve been reading the SWLing Post for a while, you’ll know I’m a big fan of the ‘2200. On the shortwaves, it’s a great performer even though the analog tuning can be a bit squirrelly.

Where it really shines is on mediumwave, though. It’s easily the best AM portable I own.

My buddy, Eric (WD8RIF), pointed out this RF-2200 (see photo above) in the flea market. Since I already own an RF-2200, I had no intention of buying one.

While taking a photo of it, the seller started telling giving me details. He said he’d never used batteries in it, and only used a small external wire antenna connected on the back (his homebrew connector was still attached). He then mentioned that he also had the original box, manuals, accessories and packing materials.

I put my camera phone away and picked it up to take a closer look. It had obviously been taken care of over the years. The battery compartment was immaculate and the telescoping whip didn’t have any bends or missing sections–it was straight, clean and original.

Out of curiosity, I asked how much he wanted for it.

He wanted $70.

Sold!

With absolutely no hesitation, I reached for my wallet. Sure, I’ve already got an RF-2200, but one can never have too many RF-2200s. Right?

I took a few photos of the RF-2200 this morning:

Without a doubt, this was my exciting 2017 flea market find. .

MFJ-8121 Analog Shortwave Portable

While browsing the inside exhibits late afternoon on Saturday, I spotted this analog portable from MFJ Enterprises.

In truth, I didn’t realize MFJ even had a shortwave portable in their product line.

This particular unit was on the clearance table and was labeled as a “factory second.” The sales person told me it was likely due to the damaged box (the unit inside had no visible blemishes).

At $12, I decided to purchase it.

You see, I get a lot of requests from readers asking for recommendations of simple analog portables. I thought I might eventually review this MFJ unit.

Last night, I popped some AA batteries in the radio and, sadly, it produced no audio. The tuning indicator works, but the speaker doesn’t even produce a hiss. I suspect this is the real reason it was being sold on the clearance table.

I might contact MFJ and let them know about this, or I might simply pop the radio open and see if it’s a broken connection.

HamSource flashlight

And finally–while not a terribly exciting purchase–I did also pick up this CREE LED flashlight at the Ham Source booth. It’s small, bright and runs on one AA battery. It has three settings: high, low and flashing. It appears to be very durable and the beam can be focused. For eight bucks, it’s the perfect flashlight to live in my new Tom Bihn Synapse 25 backpack.

That’s all, folks!

Looking back, I’m quite impressed with my self-control. I really didn’t want to return home with any new finds. If anything, I’m trying to downsize right now.

But a Panasonic RF-2200?  I always have room for another FR-2200!

Post readers: Have you acquired any flea market finds recently?  Please comment!

2017 Hamvention photos: Friday Flea Market

We had a rather long day here at the 2017 Hamvention, but we had a fantastic time. It was especially fun meeting so many SWLing Post readers and contributors in person! Thank you for stopping by our booth at 6508.

Below, I’ve posted well over one hundred photos I took at the Hamvention Flea Market this morning. Click on the thumbnail to expand each photo. I’ve tried to include price tags when available! I plan to post inside exhibit photos tomorrow.

The R-902 (XE-2)/PRD: Ed’s flea market mystery radio

Many thanks to SWLing Post contributor, Edward Ganshirt, who writes:

This radio followed me home from a flea market and I am trying to find out what it’s mission was.

I think it is a surveillance radio from the Vietnam era because of it’s low serial number #7 R-902 (XE-2)/PRD.

I can’t seem to find anything on it. It tunes from 96 to 404 MHz FM AM CW is battery powered and is totally waterproof (this would be the radio to take white water rafting) .

I would like a schematic or manual for it.

Does anyone in SWL world know anything about it?

Wow! I’m afraid I would have taken that heavy metal home with me too, Edward! And it’s waterproof? What a bonus! 🙂 Actually, I imagine since it’s waterproof, the internals are likely well-preserved.

Post readers: If you can shed some light on this model R-902, please comment. If you have a service manual or schematic, I’m sure Ed would appreciate a link/copy!

Panasonic RD-9820 on eBay

Many thanks to SWLing Post contributor, Mario Filippi, who shares an eBay link to this Panasonic RD-9820–the matching antenna coupler for the Panasonic RF-2200. Mario notes that RF-2200 owners might take note as the auction price is on a more reasonable trajectory than ones have in past auctions. This 9820 also includes the box.

Thanks for the tip, Mario!
