Winter radio life and preparing for power outages

Listening to a local station with the BC-348-Q until we lose power.

Here at SWLing Post HQ we’ve been under a Winter Storm Warning since yesterday–it’s not set to expire until sometime tomorrow. This storm hasn’t been all snow–it’s a mixture of snow and ice. If this continues, I fully expect to lose power at some point today.

In general, we’re prepared to handle this sort of thing: our refrigerator and freezer are powered by solar and completely off-grid, we have a super efficient RAIS woodstove to keep us warm and of course, we have a generator at the ready if needed.

Playing radio off-grid

As I write this post, I’m listening to the Signal Corps BC-348-Q (photo above) which is tuned to a local AM broadcaster. It’ll fill my shack with local news/tunes and its vintage valves will do a fine job warming this small room until the power eventually goes out.

When it does go out, I’ll switch to my blackout buddy, the CommRadio CR-1A.

I find that the CR-1A is nearly ideal for off-grid and field listening, as long as you have a good external antenna. The internal Li-Ion battery powers the thing for ages and it has an incredibly capable receiver.

Of course, I also have an Elecraft KX3 and KX2 which can be powered by battery, but I tend to use the CR-1A for broadcast listening and save the KX2/KX3 for off-grid ham radio QRP fun.

In addition, I have the new battery-powered CommRadio CTX-10 transceiver in the shack.

I’ve been receiving numerous emails about this particular field rig because there are so few CTX-10 reviews out there even though it’s been on the market since late July.

Please note that I’ve been giving the CTX-10 a thorough evaluation over the past few weeks and plan to publish my initial review in the next few days.

Bye-bye noise!

Even though I live in a very rural and remote area with little-to-no RFI, when the power is cut, my noise floor still drops . We’re not immune–like most homes, we have power supplies and devices that emit radio interference.

It’s funny: most urban radio enthusiasts I know don’t fear power outages, they prepare for and embrace them! When all of those RFI-spewing devices go silent, it’s simply amazing what you can hear from home on frequencies below 30 MHz with pretty much any receiver.

Personally, as long as I have a means of 1.) powering my radios, and 2.) making coffee (extremely important), I consider myself properly prepared.

I’ve always got those two points covered.

Bring it, old man winter!  I’m ready to play radio!

Contribute equipment to restore an authentic WWII B-17F heavy

Many thanks to SWLing Post contributor, Charlie Liberto (W4MEC), who shares the following:

Perhaps you could post somewhere a general call for anything WW II related that went into a B17F.

This website: http://hangarthirteen.org/ under the ‘Parts Drive‘ menu, lists the many things that will be sought after for the next few years. There might be those who monitor your site that have some of this just stored away, not knowing what to do with it or what will happen to it.

Ray is basically taking what was remaining, inspected, and approved as air worthy from this ditched plane, and building the aircraft to hook all the pieces together.

WOW! What an amazing project, Charlie!

I must say, Lucky Thirteen is in good hands.

Hangar Thirteen has chosen the best vintage radio restoration expert for the job! I’ve known Charlie for many years and not only is he an expert at restoring vintage gear, but he’s passionate about WWII era Signal Corps equipment. He brought my BC-348Q to life and patiently showed me how to align it. He also restored my Minerva Tropic Master and helped me fix the 3rd band selection on my beloved Scott Marine SLRM.

Charlie, I’ll certainly keep an eye out for the these components when I visit hamfests and will contribute anything I find or might have tucked away.

Post readers: If you happen to have any items needed in their list, please consider contributing it to the project and help this B-17F eventually have a fully-functional radio position. Of course, Hangar Thirteen is also in need of other aircraft parts–click here to check out that list.

Robert talks uBITX and navigating the world of used radio gear

Robert’s uBITX QRP transceiver kit with fire red chassis.

Many thanks to SWLing Post contributor, Robert Gulley (AK3Q), who shares the following announcement from his blog All Things Radio:

I have posted two new articles in the Reviews and How-Tos section. These were both previously published in The Spectrum Monitor magazine earlier this year.

The first article deals with buying used and new equipment, while the other article is a review of the uBITX QRP transceiver. Thanks go to Ken Reitz for graciously allowing these to be posted after their initial publication!

Many thanks for sharing, Robert!

Readers, I highly recommend both of these articles.  In his used equipment guide, Robert makes practical suggestions for navigating the world of pre-owned radio gear and shares some important tips. His uBITX QRP Transceiver article is essential reading for anyone who has considered building this incredibly affordable kit.
