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:

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!

“Project Outreach”

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.

Stereo! – Degen DE23

After circling central Virginia one time in a USPS truck, my Degen DE23 finally landed and was delivered a day early from eBay. Why spend $35 for a 13-year-old radio? The simple answer is stereo speakers with an AUX input. That’s a combo I don’t have among the 50-something radios lying about (yeah, things are getting out of hand again), and something I’d like to use to enhance the sound of some other radios, notably the Si4732 Pocket Mini.1 And it looks cool.

My Amazon Product Reviews

I’ve written product reviews on Amazon for years, over 300 of them. It’s not unusual for a product I write about here to have a corresponding Amazon review. I recently changed my public name on Amazon to “Blog or Die!” and here I am publishing a link to my Amazon content:

Blog or Die! Product Reviews on Amazon.com

The reviews are often simplified, and I write them for a different audience.

Voyage of Discovery: Degen 1131

The radio arrived today from eBay seller Hisonic, costing me a paltry $19.99 plus tax. Here’s the stock photo again:

Degen DE1131 MW/FM/SW radio, MP3 Player

To tell the truth, I was contemplating sending it back as defective. Nothing worked. The radio came on and the buttons beeped when I pressed them, but nothing happened. I finally got “Radio” on the menu, but the SW, MW, FM buttons did nothing. It kept freezing up. I really thought I had a badly defective radio.

Second Impressions

I was wrong. The radio isn’t defective; it’s buggy and weird. I was prepared for some of the weirdness based on my experience with the Degen DE28 and the Kaito KA29, contemporary menu-driven radios from the same manufacturer. One important concept is delay. There is a delay sometimes between when you hit a button and when the radio responds to the button. This can result in the radio getting behind. You can hold down the tuning slider for a little and release — the radio will keep tuning until it catches up. Sometimes, the button just doesn’t work and it requires multiple presses. Sometimes it starts tuning in the opposite direction from the button pressed. It can be frustrating to use.
