Arcing can produce nasty broadband radio interference

On this trip to Québec, indoor listening has been more productive than listening from our balcony.

I mentioned in a previous post that, this year, QRM levels here at the condo in Québec are higher on our balcony than they are inside the building.

I think I found the source.

A couple weeks ago, on my morning walk, I passed underneath some high voltage power lines about 1 km from the condo. I noticed the sound of arcing coming from a pole nearby. No doubt, something metal–a staple, a cable, a pin, etc.–is the culprit.

I pulled out my smart phone and made this short video. If you turn up the volume, you might hear the noise especially at the end of the clip.:

I took a portable radio back to the site later and heard the same broadband noise I heard from the condo.

Although we only rent this condo a couple months a year, I’ll try to report the noise to the Hydro Québec. I know that our utility company in the States must follow up with requests like this and do their best to eliminate unintentional sources of RFI. These issues can also be an indication of something in the system failing, so power companies can actually be quite grateful for the feedback.

If you have persistent broadband noise at home, check out some of the trouble shooting tutorials at K3RFI’s website for a little guidance.

Despite all of this noise, I’m pleased I can still receive a few of my favorite shortwave stations. And, of course, escape to the KiwiSDR network and hit the field from time to time!

No worries, though, I’ll be back at my home station soon and can once again enjoy a relatively RFI-free radio space!

Cryptocurrency transactions over solar-powered shortwave radios

Devs used solar-powered radios to complete first ‘off-grid’ cryptocurrency transaction

Could blockchain help after disaster strikes?

A group of developers claim to have performed a solar-powered cryptocurrency transaction, using shortwave radios and blockchain tech. While it might not be the world’s first radio-transmitted cryptocurrency transaction, the devs insist it is the first one to be completed entirely off-grid.

They managed to do it with just a portable hard drive, a solar battery pack, a shortwave radio, and, of course, some technical know-how.

In addition to these gadgets, the developers used open-source cryptocurrency Burst to conduct the experiment. For the record, the transaction was recorded on Burst’s blockchain without the need for any mains power or data connections.

One of the developers, Daniel Jones, has since teased an image of the improvised setup on Twitter:

The Icom IC-7200 has been discontinued (yet again)

Many thanks to SWLing Post contributors Dave Zantow (N9EWO) and Larry W who both note that the IC-7200 has been discontinued once again by Icom. Universal Radio has even listed it as discontinued on their website and doesn’t appear to have any in new inventory.

You might recall that Icom discontinued the IC-7200 in early 2016 and re-introduced it exactly one year later in 2017.

I consider the IC-7200 to be one of the best general coverage transceivers for broadcast listening under $1,000 US. Used IC-7200s can be found for excellent prices–I’ve seen many at hamfests for $650 (like new) and much less.

Spotted at a local hamfest earlier this year: The IC-7200

It appears that GigaParts and Ham Radio Outlet still have the ‘7200 in stock and shipping for $749.95 US after rebates. Of course, you can also find them on eBay.

Reader seeks Radio Bulgaria jingle

Many thanks to SWLing Post reader, Sarkis, who writes with the following inquiry:

I thought I would turn to the SWLing Post for some advice please.

I am trying to find recordings of Radio Bulgaria’s Italian Service which was taken off the air in 1997.

I’m after a jingle with which the current affairs programme started. If my memory serves me right, it was Italo Disco style.

Thank you in advance!

Kind regards,
Sarkis

Post readers: Does anyone have a recording of this jingle or remember the tune? Please feel free to comment with any details or a link to the recording!

Radio City is closing shop

Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who notes that Radio City in Mounds View, MN, will be closing its doors soon.

Ham City owners, Dan and Maline Fish, are retiring. They posted the following message on their website:


Sept. 11th, 2018

It’s Time to Retire.

Dan and Maline Fish of Radio City

It’s been a wonderful 36 years for us at Radio City and we have decided to retire and close Radio City. 🙁 We are so thankful for the many years of support and we have enjoyed working you, our customers. The technical, intelligent and polite conversations plus advice have been invigorating, thus making this decision extremely difficult for us.

We appreciate all the teachers, Elmers, VE examiners, ham and astronomy clubs efforts in growing new ham radio operators and amateur astronomers into our special community.

We will also miss going to and supporting amateur radio and astronomy clubs all over MN and IA at their events. We will greatly miss all the friendships we have been privileged to maintain with many of our customers.

We plan to exit by this year’s end or a bit sooner as we empty our shelves of new and used materials.

Upcoming Events:

Final Goodbye Tour:

We will be at Smartfest in Cologne, MN on Saturday September 22nd. We will also be in Carlton MN for their Fallfest on Saturday September 29th.

Goodbye Party:

Please come on by on Saturday October 6th for our good bye party. We will of course have cake and coffee for everybody.

Other Necessary Details:

Service:

We will complete servicing items we currently have in the service dept. We will not be accepting any additional ‘Out of warranty’ items. ‘In warranty’ items will be still be processed by Radio City per normal until about October 31st, 2018.

Consignment :

We will no longer accept more items for consignment. All items that have NOT been sold need to be picked up the week of Oct 13th, 2018. We will consider all items not picked up by then to be abandoned.

In closing we will very much miss all of you and perhaps there is someone out there interested in running the store under New Management.

Thanks again for all your support,
Dan and Maline Fish

Radio Deal: Eton Executive Traveler $49.65 shipped

Many thanks to SWLing Post contributor, Christian, who writes:

Another Grundig/Eton deal on Amazon. This time the Eton Exectutive Traveler for $46.65 shipped. One of the lowest prices I’ve seen on this one. I already have a Traveler so no plans to purchase, but thought your readers might be interested. Good little radio if you ask me. Esp. the executive version as I like the case. Again we’re talking Amazon here so the price can change based on demand.

Thanks for the tip, Christian!
