An EDC Bag for the Classic Sony ICF-SW100 Receiver

In a 2014 article, this site’s administrator Thomas Witherspoon introduced readers to the CIA’s Survival Kit which is housed in a superbly sturdy waistpack, the Maxpedition M-2. Thomas observed that the M-2 pouch is perfectly suited to holding the diminutive Sony ICF-SW100 receiver.

I was intrigued by that possibility, but only recently tried to combine the two after I resurrected another ICF-SW100 that fell silent to the chronic broken ribbon cable problem. Indeed, the radio is a perfect fit and the M-2 is impressively solid and well designed. I was not aware of the Maxpedition firm prior to learning of the M-2 bag, but I see in various forums they are a major player in well-made gear for the survivalist and outdoor enthusiast crowds. The M-2 is a very popular item, and one or more of the four available colors are sometimes out of stock at the manufacturer. Fortunately there are many sellers on Amazon and Ebay who have these waistpacks available.

What is EDC you may ask? It refers to “Every Day Carry”, the essentials that an individual deems necessary for their lifestyle or a particular activity. For me, an EDC bag is taken along on hikes or other outings to the countryside and typically contains a compact shortwave radio and related accessories. It’s always fun to stop for lunch or a break in a remote location and be able to search for interesting stations whenever the mood strikes.

This photo shows what I’m able to carry in the Maxpedition M-2 bag; a coffee mug is shown for size comparison. Contents of the “kit” include:

  • The Sony ICF-SW100 receiver
  • Zero Audio Carbo Tenore In-Ear Monitors & soft pouch
  • Sony AN-71 reel-up antenna
  • Panasonic RR-XS400 Digital Voice Recorder
  • Short 3.5mm male-to-male stereo audio patch cable
  • Two extra AA batteries for the Sony receiver
  • An extra AAA battery for the Panasonic Digital Voice Recorder

A few comments on the contents. The Zero Audio Carbo Tenore In-Ear Monitors (IEMs) provide excellent audio quality for their price. They are among a handful of IEMs regularly recommended by budget-minded audiophiles on the popular Head-fi.org site. I like these IEMs not only for the audio quality, but also their small size (in the cloth bag) which barely fits into the M-2’s main compartment along with the ICF-SW100. Larger earbuds or IEMs might not fit the M-2 without being mangled by the hefty YKK zippers. One caution: the similar Carbo Basso model by Zero Audio is deemed by many to be overly heavy on the bass frequencies. I find the Carbo Tenore to be more than sufficient for bass heavy genres like Electronica.

The Panasonic RR-XS400 digital voice recorder has been out of production a few years, but is a highly capable and compact recorder. It contains a hidden USB plug for charging and data transfer, has a fully featured and backlit LCD display, built-in stereo microphones, switchable LINE/MIC inputs, and other useful features. In excellent used condition the RR-XS400 is worth about $50 USD in 2017, despite some Amazon sellers trying to move them at the original $280 price.

The extra AAA battery for the recorder slips into the front pouch of the M-2 bag along with the Sony AN-71 antenna. The additional AA batteries for the radio, however, are held in the two “pen loops” on the left and right of the M-2. Despite these loops being open-bottomed tubes, the fit is tight enough to hold the batteries securely.

Like every portion of the Maxpedition M-2 bag, the belt loop is proportioned perfectly and sewn with precision. With the Sony ICF-SW100 EDC “kit” secured to my belt on a hike, I’m assured of quick access to a DXing opportunity, such as when hiking the Naches Loop Trail near beautiful Mt. Rainier:

Michelle Guthrie: ABC cut shortwave to operate within “funding envelop”

(Source: The Guardian via Phil Brennan)

The ABC’s managing director, Michelle Guthrie, has told Senate estimates she believes it is not her job to lobby government for more funding for the broadcaster but to work within the budget she is given.

Under questioning at a fiery Senate estimates committee, Guthrie revealed she saw her role as a manager rather than an advocate for more funding, a marked difference from her predecessor Mark Scott who was a consistent lobbyist for additional funding and critic of government cuts.

“On my second day in the job I was handed down the triennial funding in the May budget and as far as I’m concerned we operate within that three-year funding envelope,” Guthrie said.

Asked repeatedly if she believed it was her role to seek more funding to fulfil the ABC’s charter she said no because her focus was on providing content and operating efficiently.

[…]“I think what you’re asking is reasonably hypothetical. We are operating within the government’s funding envelope and making decisions on audience behaviour and technological advancement.”

She also refused to concede that anyone other than the 15 people who called the ABC to complain, or the 51 who gave submissions to a Senate committee, had been affected by the decision to scrap the shortwave radio service.

She appeared before a Senate estimates committee on Tuesday, answering questions about the decision to end the broadcasting of local radio through shortwave channels in the Northern Territory and Pacific region. The decision was been widely criticised, including by all major parties.

Guthrie was unable to provide evidence of prior consultation on the decision and claimed the ABC was not the official emergency broadcaster.

Asked by Greens senator Scott Ludlam about the “extraordinary cuts” to Radio National features, religion and music, Guthrie dismissed his premise, saying: “I wouldn’t characterise taking three music programs away from RN as an extraordinary decision.”[…]

Raspberry Pi WiFi Radio with touch screen

For those of us who like to tinker with the Raspberry Pi, this looks like a fun weekend project.

It’s multi-step, but I believe this project could be completed by almost anyone–you wouldn’t have to be a Raspberry Pi or Python guru (code snippets can be downloaded, for example).

Here’s a short video demonstration of the finished Raspberry Pi Touchscreen WiFi Radio:
