The new Elecraft K4

Today, prior to the open of the 2019 Hamvention, I had an opportunity to hang with the folks at Elecraft and grab some photos of their newest transceiver: the Elecraft K4 direct-sampling SDR (click here to read the announcement).

Elecraft has now published a K4 product page on their website with information about pre-orderswith information about pre-orders. In short, the base model—which includes two full receivers—starts at $3999 US.

Wayne Burdick told me that they expect to start shipping the K4 by the end of 2019.

I snapped a number of photos of the two engineering prototypes of the K4 this morning in Building 1 at the 2019 Hamvention.

Cyclone Fani: How Ashok prepared for this powerful storm

2 Replies

Category 4 Cyclonic Storm Fani was the strongest tropical cyclone to strike the Indian state of Odisha since Phailin in 2013.

Many thanks to SWLing Post contributor, Ashok Shankar Das, who shares the following post from his blog SWLDAS:

The extremely severe cyclonic storm #Fani recently visited Odisha. It is Peculiar to have a Cyclone in this time of year. Though history says earlier there are some cyclones hit Odisha coast during this summer season.

[…]I have seen several Cyclones including #1999SuperCyclone . Though Super cyclone has done a lot of damage, this one is no less. Wind speed of 200kmph with gust 220 to 250 kmph ripped everything in its path. major damages to infrastructures like power grids, cell towers under construction buildings are name a few.

My Preparedness

The CountyComm GP5-SSB

See this SWLING article–I was runner-up in that challenge. My preparation for Cyclone Fani was as per I have described. Well Not all. I have charged emergency light, arranged candles and lantern. Stocked Biscuits and Flat rice. Stored around 15Liters of drinking water. Emergency medicines and fully Charged 3 Baofeng Walkie Talkies.

The GP5SSB I got as a gift from SWLING Post, put new battery in it. I have downed external antennae for HF and VHF. Baofeng handys are quite good as scanner. I monitored HAM band so I could know the situation in surrounding area and also if situation arises I could give a distress call to Nearby monitoring person. But that situation didn’t arise.

HAM volunteers from WBRC started their communication service since 5th May. They Have setup a VHF in state control room at Bhubaneswar, ADM office Puri and Khurda.
Since 5th may onward I was monitoring and in QSO with VU2IPL(Suresh). VU2FTP VU2XRY VU3YDA and VU3OXI are handling the communication between Puri, Khurda and Bhubaneswar.[…]

Thank you for sharing this, Ashok and we’re very pleased that you made it through this extremely dangerous storm well-prepared. It sounds like your community has a good ham radio communications network at the ready as well.

Ashok, you are reminding me that it’s time to dream up another Virtual Radio Challenge along with an enticing prize. I’ll start putting one together! Perhaps I can find a prize at the Hamvention this week. Stay tuned…

Radio Deal: Eton Executive Satellite $96.68 shipped

5 Replies

Many thanks to SWLing Post contributor, Gregg Freeby, who writes:

I just noticed the Eton Executive Satellite is now priced under $100 on Amazon. I’m sure it will change again soon but this is the lowest I’ve seen it at $96.68 at the time of this writing. Not too many sub $100 radios out there with the features this radio has. I also noticed that this radio is “sold out” on the Eton website – they actually point you to Amazon, so it may be reaching it’s end of life from a retail standpoint.

Wow–Gregg this is the best price I’ve ever seen on the Executive Satellite.  If you’ve been considering one, this would be the time to pull the trigger. I have the non-executive version, but I’m still tempted to snag one of these. It is an excellent performer and the audio from the internal speaker is better than most other portables its size.

The ALT-512: A new QRP transceiver

1 Reply

There’s a new QRP transceiver on the market: the twelve band ALT-512 by Aerial-51.

At first glance, you’ll see a similarity between the ALT-512 and the LnR Precision LD-11/Aerial-51 SKY-SDR. The LD-11 and SKY-SDR, are very similar, save the LD-11 is marketed to North America (via LnR) and the SKY-SDR to Europe. The SKY-SDR had several iterative upgrades, most importantly the dual-threaded software used in the firmware, which cut CPU latency in half. Both the LD-11, SKY-SDR and now the ALT-512 are made in Europe.

Click here to read my review of the LnR Precision LD-11.

According to Aerial-51, the new ALT-512 is built on the LD-11/SKY-SDR platform, has the same chassis design but has many improvements over the SKY-SDR:

  • 4m Band
  • 2.4 in. Color Display
  • Improved receiver pre-amplifier
  • 2 transistors in the transmitter PA (was 1)
  • Waterfall in addition to the Pan-Adapter Bandscope
  • 4 additional front-panel buttons
  • User friendly front-panel adjustment of often used parameters (formerly embedded within the software menu)
  • FULL TS-2000 command set implementation
  • Built-in Sound Card; Digi Modes run using only one USB-2 cable connected to the PC. No additional hardware required.

If the ALT-512 performs as well as or better than its predecessor, it’ll certainly be a great little QRP radio.

Pricing has not yet been posted, but Aerial-51 plans to make this transceiver available in the next few weeks.

A Panasonic RF-2200 in “The Walking Dead”

Panasonic RF-2200

Many thanks to SWLing Post contributor, Balázs, who adds the following note to his recent radio sighting (of a Hallicrafters HT-32 Transmitter) in the series “The Walking Dead.”

Balázs notes that in the season nine finale, he spotted the previously mentioned HT-32 (see image below), in addition to the iconic Panasonic RF-2200 (see image above).

Hallicrafters HT-32 Transmitter

Honestly, I think both of these radios would serve you well in a post-apocalyptic world!

Turns out, The Walking Dead is filmed in Senoia, and Fayetteville, Georgia, USA and SWLing Post contributor, Steve Yothment, lives nearby. As the then president of his radio club, he was consulted last year about radio gear to use on The Walking Dead set. He tells us to look out for an HF amplifier and field strength meter in future episodes! How cool is that?!

I’ll add this post to our ever growing archive of radios in film!

Sangean HDR-15/DPR-64 and notes from 2019 catalogs

The Sangean HDR-15

Many thanks to SWLing Post contributor, Mike Schuster who writes:

Hi Thomas,

Sangean has quietly buried yet another AM/FM HD radio in the PDF of their US 2019 catalog [download as a PDF].

It’s the HDR-15 which appears to be a small clock radio/phone dock [photo above].

Also, in their European catalog [click here to download as PDF] they are transitioning all of the model names to a more descriptive grouping. So the SR-35 is now the “Pocket 100”, the DT-160 is now the “Pocket 160”, and the DT-800 is the “Pocket 800”.

There is also a new DAB+ portable, the DPR-64 (em … er …”Pocket 640“) whose cabinet is rounder and smaller than the DPR-65 (em … er … “Traveller 650“) whose cabinet they adapted for the American HDR-14. Wonder if there will be a forthcoming US HD-radio portable based on this cabinet design. This looks very interesting to me as a potential DAB+ travel radio, priced at about $100 and already available from several European and Australian electronics houses.

Thanks for the tip, Mike! I enjoyed checking out both the US and European catalogs. Sangean is certainly embracing DAB+ and HD Radio.

I see Sangean also includes two shortwave radios: the ATS-909X and ATS-405.

In the EU catalog, they’re referred to as the “Discover 909X” and the “Discover 405.”

Dave updates and expands AOR AR-DV1 review

Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who writes:

A greatly updated and expanded review on the AOR AR-DV1 has now been posted by me. Made a few typo corrections and some minor text changes from the first draft a few days ago, so I hope I have all of those fixed now ?

http://n9ewo.angelfire.com/ardv1.html

Also just updated (again) the Sangean DAR-101 MP3 recorder review. Some minor text changes plus added 4 internal photos (bottom of it’s page). I have never seen any internal photos anywhere on the internet of the DAR-101. Now there is.

http://n9ewo.angelfire.com/dar101.html

Again for reading any of my web pages, be sure and have your Pop Up stopper on FULL (do not allow ANY pop ups) and your security settings on your browser set at least to default. Otherwise Angelfire can be rather nasty with junk. If all else fails turn off your Java Script.

Many thanks for sharing, Dave!
