The uBITX V6 is a power outage companion

QRPer Readers: Please note that the following is a cross-post from my other radio blog, the SWLing Post. For more information about the uBITX V6 and a short post about assembling it, check out this post.


Yesterday, a weather front moved through the area that dropped temperatures from an unseasonably high of 50F to 25F in the space of a couple of hours.  Fronts like this always equate to high winds here at our altitude. This time, it packed a little snow as well.

Last night, around 22:00 local, our power went out due to a fallen tree further down the road.

Here at SWLing Post HQ, we don’t panic about power outages. As I’ve mentioned before, our refrigerator, freezer and some of our home lighting is solar-powered and off-grid–we also rely on passive solar heating and a good wood stove to keep us warm and cozy.

Without fail, I always use power outages as an excuse to play radio on battery power.

This morning, the uBITX V6 transceiver was already hooked up to a LiFePo battery on my desktop, so I simply turned it on and started tuning around the 40 meter band, where I had recently logged a few POTA contacts. Problem was, the band was absolutely dead, save a couple weak stations. After thinking about it a few seconds (keep in mind this was pre-coffee) I put on my boots and coat, walked outside and confirmed my suspicions: the antenna feedline had become detached from my external ATU box.

The winds were strong enough last night, that the ladder line pulled itself out of the banana connector jacks on the side of the ATU box. This happens quite often during periods of high winds and is a bit annoying. Of course, I could secure the feedline in such a way that it would easily survive high winds without disconnecting, but frankly this is an intentional design choice. You see, when a black bear walks into my feedline, it easily disconnects before the bear gets tangled, up, frustrated and yanks my antenna out of the tree!

Trust me on this: bears and antennas don’t mix. I speak from experience.

After re-connecting the antenna, I fired up my portable alcohol stove (the one you might have seen in this post), boiled water, and made a fresh cup of coffee to take back to the shack.

I turned on the uBITX once again and found that the 40 meter band was chock-full of strong signals.

It’s time to go chase a few more parks today and plot my next POTA activation.

Frankly, I’m in no hurry for the power to be restored.  It’s a wonderful excuse to play radio.

TK0C 2019 Contest Video

Many thanks to Paul (W4/VP9KF), who shares the following:

Having almost become a TK resident, this is one of the best ever contest
videos ever:

I recognise their QTH and so wish I’d been there!!!!!!

Thanks for sharing this, Paul! An amazing amount of effort was certainly put into this contest and no doubt it paid off!

Icom IC-705 price and availability

Note: We will update this post as pricing information is confirmed by retailers. This is a cross-post from our other radio blog, the SWLing Post.

Many thanks to several SWLing Post readers who have been carefully tracking the price of the Icom IC-705 transceiver which is expected to start shipping around the second quarter of 2020.

Pricing in Japan: 124,800 yen

Paul Evans notes that the price in Japan, according to this Icom Japan press release [PDF], is 124,800 yen + tax. That’s roughly $1150-1200 USD.

Pricing in UK: £1200.

In addition, ML&S have recently posted updated details from Icom UK and have noted that they “anticipate a price of around £1200.” To put that in perspective, the IC-7300 is currently being offered for the same price and it’s been on the market a while now.

This could mean that after the IC-705 has been on the market for a while, discounts could place it well below that of the IC-7300. Of course, if history is an indicator, early adopters will likely pay the top price.

Pricing in US: [TBD]

No confirmation yet from US retailers, but at this point, I would bet we could see pricing around $999 USD. That would be a competitive starting point. Of course, once we have confirmation from retailers we’ll update this with actual figures.

Other regional pricing

We will update this post with pricing and availability once we confirm details. Please comment with any tips!

uBITX v6 QRP transceiver now available for $150/$199 US

Many thanks to QRPer, Pete (WB9FLW), who notes that Ashhar Farhan (VU2ESE) has recently announced the availability of the uBITX v 6.0–as Pete notes, “just in time for the Holidays!

Pete shared the following message from Farhan:

Here is what [the uBITx v 6.0] looks like :

And of course, you can buy it on hfsignals.com. The shipping will happen from Tuesday onwards. We have a limited supply of the first 200 boards. The rest is for after Christmas.

The most important thing about this revision is that the Radio circuitry is almost unchanged. We have incorporated the connectors on the PCBs. So, this kit needs none of the confusing soldering. You snap in the TFT Raduino onto the main board, plug the power and antenna from the back, snap on headphones, plug in the mic (supplied with the kit) and off you go!

It is offered in two kits now : The basic kit (150 USD) is without the box (like old times) but with a microphone and two acrylic templates for the front and back panels.

The Full kit (199 USD) has the box with speaker, mounting hardware etc. Both are described on the website.

Now, about the TFT display:

For those who are using the 16×2 display and you would like to upgrade, you will have to do three things:

Add a heatsink to the 7805 of the raduino

Buy [here] and hook it up as per [this article].

Grab the new Arduino sketch from https://github.com/afarhan/ubitxv6

Background:

I have been hacking away at adding a TFT display for the Arduino for sometime. Finally, I managed to do this with a really inexpensive 2.8 inch TFT display that uses a controller called the ILI9341. The display update is slow but, clever guy that I am, the display very usable. it uses the same pins that earlier connected to the 16×2 LCD display. This display is available everywhere for a few dollars.

Many thanks, Pete, for sharing this announcement. The price was simply too attractive to me, so I just purchased the full kit for $199 US. (Thanks for being the good enabler you are, Pete!)

I’ll post an update when I receive the transceiver and assemble it. I do hope this is a workable little radio–it would be pretty amazing for newcomers to the hobby to be able to get on the HF bands for a mere $200 US. I also love the fact that this is all based on open-source, hackable technologies.

Cold War Sports: High-Speed Telegraphy

Many thanks to Paul Evans, who shares the following short radio documentary from the BBC World Service:

The end of the Cold War in 1989 spelt the demise of a little-known, but surprisingly popular sport behind the Iron Curtain – high-speed telegraphy competitions. With the help of two of Czechoslovakia’s best former Morse-coders, we revisit the inaugural World Championship in Moscow in 1983 when the Soviet Union rolled out the red carpet for teams from across the Communist bloc. Ashley Byrne reports. The programme is a Made-In-Manchester Production.

As Paul points out, “HST is still going strong as a sport!” Indeed it is because CW is simply timeless! Thanks for the tip, Paul!
