Incoming Radio: Jazmm 6f9846ec-031e-4f5a-876d-0ee9460591cb

OK, it will soon be my birthday and so I blew a big $25 (after 20% discount) plus tax for a pocket shortwave radio. I asked Rufus (Amazon AI assistant) and it said the model number was: 6f9846ec-031e-4f5a-876d-0ee9460591cb, and apparently that really is the model number. I’m going to have a hard time remembering that. The manufacturer is Jimeng, and so far no manual is to be found online. Amazon, however, has a couple of videos that cover operation in some detail, one that appears to be from the manufacturer and one from a user who found what he described as “hidden features.”

Jazmm Bluetooth AM FM Shortwave Radio with NOAA Weather Alert

I’m a sucker for small radios, and this one seems pretty small, 2.3″L x 4″W x 1.3″H, although that’s a bit thick due to the speaker and belt clip. In addition to MW/FM/SW it adds weather band, Bluetooth and MP3 play. It may act as a computer speaker if “USB MP3 Play” means that. [Update: it doesn’t work as a USB speaker, nor does plugging in a USB flash drive do anything.] It’s described as having NOAA weather alerts. Shortwave coverage is 4.75-21.85 MHz. There is some sort of auto-scan feature with 100 station presets. The odd thing about this radio is that every picture of it online shows the same 162.585 MHz display, which is not a frequency the radio is supposed to receive.

My main reasons for the purchase was the high reviews given to the speaker, the small size and the flashlight. Negatives include a non-replaceable battery, product reviews saying shortwave was weak with the telescopic antenna, and the radio being on the thick side.

One Amazon reviewer thought it would be better without the belt clip. Another said the earphone output was mono on FM, but that it played stereo from MP3 files. Overall ratings were 4.3 stars.

Radio en Úbeda

I want to make a bit of a change in the blog and I haven’t quite figured how to do it. The idea is to add some travel content and some photography, but without watering down the radio focus. It may be a separate blog, maybe something like travel.blogordie.com. We’ll see, but in the meantime, here’s a crossover piece sharing some radio reception I had in Úbeda, Spain, on June 4, at around sunset local time, 19:30 UTC. (Somehow I can’t hear the town name without thinking of EBITDA).

Here’s a photo snapped of the RTVE tower in Madrid (not where these transmissions are coming from).

RTVE Tower Madrid

The video features the ATS results from my Qodosen DX-286 using a Sangean ANT-60 reel antenna strung out in a city park. I quickly recognized Radio Romania, Radio Exterior de España, and many Chinese stations–good signals and a much different selection from what I would have heard in the US. Time in UTC is on the radio (approximately).

About

How did this blog about shortwave radios come to be?

My first domain was Davnet.org in 2002. The oldest version of my website on the Wayback Machine dates back to to August 2003, when it was pretty well developed. I found an older kwdavids.net version from February 2, 2001 but it is a hijacked version with advertising slathered in. I’m pretty sure  my first web page was far older than that, hosted by an ISP, under their domain name. I have an article here, transferred from that site dated in 1995.

The banner of that website has these prophetic words:

Find out who I am by reading my web site
and I will find out who I am by writing it.

Blogging has always been a voyage of self-discovery for me.

Arrived In Time: AMNVOLT ATS Mini (Updated)

Thanks to AliExpress and their downstream agents, my shiny new AMNVOLT ATS Mini arrived in time for my trip to Spain and avoiding a hulking batch of new tariffs:

AMNVOLT ATS Mini and accessories

First Impressions

My first observation is that the box wasn’t half crushed like the prior one, and the instructions seem professionally printed. The case fits together without a big crack. This is definitely a higher build quality product. It came with V1.01 of the firmware. And yes, headphones work. Yea! The front and back printed Quick Start Manual actually names the product. AMNVOLT is the manufacturer and ATS MINI is the model name. (My former was called a “Mini Radio” or “ESP32 Si4372 Receiver.” And according to the ATSMINI page on github, mine is version 3.

Looking for the Ultimate Travel Radio

I like to take my shortwave listening hobby with me when I travel.

Tecsun PL-380

I think my first international trip with a radio was in 2011 and the radio was a Tecsun PL-380 that I bought around the end of 2011. I think the first trip with it was to Costa Rica in 2012.

I heard: HCJB (Updated)

When I was a kid, HCJB from Quito Ecuador was a station heard worldwide. One of their QSL cards celebrated a new hydro power station to boost their output even more!

“The Voice of the Andes”
“Project Outreach”
HCJB QSL, circa 1965

That power station is now part of the Ecuadoran national electric grid. Reach Beyond Australia in Kununurra in far north Western Australia carries on the HCJB legacy internationally.1

Incoming Radio: Si4732 Pocket Mini (again)

I already have an Si4732 Pocket Mini, aka ATS-MINI radio, but there is an improved version with some important advances:

  1. Hi-Z antenna input for greater sensitivity
  2. Separate headphone amplifier circuit
  3. Improved speaker

Here’s a video about the new version:

I’m assuming it will have the latest firmware on it and I will likely keep this one on the main firmware track and the one I have now on the G8PTN branch. [Update: I decided to keep both on the main firmware branch.]

I hope what I ordered is an “official one” (I think the previous one was not). The picture looks like it:

I selected the one with the black donut antenna labeled 10 kHz – 18o MHz. The previous one was the red version. I already have a telescopic antenna for it.

The arrival date is set for May 27, which taking into account recent experience with AliExpress, means it should be May 26.
