REVIEW - RadioIntel.

No representation is made that the following information is entirely free of mistakes.

1. Introduction:

The Sony ICF-S10MK2 is an "FM/AM 2-Band Pocket Radio" made in China. Cost including shipping and taxes is $10.55 when ordered directly from Sony's website. Can this inexpensive radio be used to pursue the hobby of AM distance reception (AM DX)?

2. Features:

The front includes a tuning scale, LED-tuning indicator, and built-in speaker. The right panel contains a tuning dial and AM/FM band switch. The left panel includes a power-switch volume-control wheel, earphone jack, carrying strap, and telescoping FM antenna. There is a rear battery compartment.

Note: The red tuning LED grows faint when the batteries need replacing.
Note: An internal ferrite bar is used for AM reception, not the telescoping antenna.

3. Specifications:

* Reception: 530 kHz to 1650 kHz AM and 87.5 MHz to 108.0 MHz FM.
* Output: 100 mW at 10% THD via a 2.25" (5.7 cm) speaker.
* Power: 3 Volts via 2 "AA" (R6) batteries, not included.
* Battery Life: FM ~40 hours and AM ~45 hours.
* Dimensions: 2.875" x 4.750" x 1.188" (71 mm x 119 mm x 30 mm) WHD.
* Weight: 7 ounces (202 grams) with batteries.
* Warranty: 1 year limited.

Note: Although Sony's literature states an AM tuning range of 530 kHz to 1710 kHz, testing revealed a range of 530 kHz to 1650 kHz.

4. The AM DX Hobby

The hobby of AM distance reception goes by two names: MW (mediumwave) DX and BCB (broadcast band) DX. The object is to identify (ID) and log stations using: time, call sign (usually given each half-hour), frequency, content, language, or local color (ex. weather or commercials).

Reception is best during the winter, decent in the fall, and poor in the summer. Daytime reception is poorer than nighttime reception. Nighttime offers less noise and some stations reduce or discontinue power. At local sunset stations to the west can be heard as stations in the east power down for the night, this is called "gray path" reception. Different catches will be made at sunrise, daytime, sunset, and nighttime. Station tests are often performed late on Sunday night. Conditions change minute by minute as stations fade in and out.

Clear channel stations with up to 50 kW power are located at: 540, 640-780, 800-900, 940, 990-1140, 1160-1220, and 1500-1580 kHz. Local channels (called the "graveyard") with 1 kW or less power are located at: 1230, 1240, 1340, 1400, 1450, and 1490 kHz. The graveyard contains many interfering signals. All other channels below 1610 kHz are considered regional, having 10 kW or less power. The "expanded AM band" runs from 1610 to 1710 kHz.

Some collect QSL (reception) cards. Simply mail the station a reception report consisting of the: date, time and time zone, frequency, program details (station ID, program name, host, commercials, etc.), and how well the signal was received (excellent, good, fair, poor). Make sure to include your name, address, and return postage! Making a recording of the broadcast will definitely help.

For station identification see WRTH (World Radio and TV Handbook), a yearly publication. Or visit the following websites:

For more AM DX information including when stations perform DX and equipment tests join either the National Radio Club (NRC) or the International Radio Club of America (IRCA).
