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!

The CommRadio CTX-10 has landed

Yesterday, UPS delivered a much-anticipated package: the CTX-10 QRP transceiver from CommRadio.

CommRadio dispatched this loaner CTX-10 for evaluation and I’m excited to get my hands on it since it’s not everyday I get to evaluate a transceiver designed around field portability (my favorite category of gear).

Yesterday, I took a few shots of the CTX-10 as I unpacked it:

I’ll need to build a fused power cable with the supplied pigtail and also sort out an 8 conductor (Yaesu compatible) modular plug microphone. Of course, I’ll give this radio a thorough review testing it on SSB, CW and digital modes (especially FT8).

Since the CTX-10 is built on the CommRadio CR-1 and CR-1A I anticipate a capable receiver section (in other words, expectations are high). Of course, I’ll test the CTX-10’s ability as a broadcast receiver as well.

CommRadio CTX-10 availability update

The CommRadio CTX-10 QRP transceiver

Universal Radio is now taking orders for the CommRadio CTX-10 QRP transceiver. The price is $999.99 and the expected shipping date is March 1, 2018. Universal notes that they will not charge customers until the units begin shipping.

Once radios are in production, I plan to review the CTX-10.

CommRadio CTX-10 approved by FCC

Many thanks to SWLing Post contributor, R. Lewis (KF5GV), who writes:

Just noticed on Universal Radio web page the Comm Radio CTX-10 has been approved by the FCC. They are accepting pre-orders on Dec 1. No indication of pricing but hope they announce it soon.

Thanks for the tip!

I’m looking forward to checking out the CommRadio CTX-10. For one thing, it’s in one of my favorite radio categories: portable general coverage QRP transceivers!

Since the CTX-10 receiver is likely an iteration of the excellent CommRadio CR1 series, I expect it’ll perform well on the broadcast bands as well as the ham bands. I look forward to reviewing the CTX-10.

The CommRadio CR-1a has been discontinued

Many thanks to SWLing Post contributors R. Lewis (KF5GV/HS1) and Dave Zantow (N9EWO) who’ve both noted that the CommRadio CR-1a receiver has been listed as “discontinued” by Universal Radio, and HRO.

I imagine CommRadio has stopped manufacturing the CR-1a as they gear up for production of the new CTX-10 10 watt QRP general coverage transceiver.

If you’ve been considering the purchase of a CR-1a receiver, note you might find one on the used market (check with Universal Radio) as some owners upgrade to the CTX-10 transceiver next year. I expect the CTX-10’s receiver to be on par with the CR-1a, if not a little better.

On that note, I plan to review the CTX-10 and, of course, give its general coverage receiver a thorough workout on the broadcast bands once the unit has been released in 2017.
