Schedule: typically continuous. As an experimental broadcast, the 25 MHz signal may be interrupted or suspended without notice.

Radiated Power: 2.0 kW

Antenna: Experimental Turnstile

The Digitech AR-1780: a new SSB shortwave portable

[UPDATE: Click here to read our full review of the Digitech AR-1780.]

Many thanks to SWLing Post contributor, Cap Tux, who writes:

This radio seems to have recently been released in Oz, no idea of its performance on SSB et al. but seems to do everything the C.Crane Skywave does. Heavy on batteries though at 4 x AA and nearly twice as heavy with similar dimensions to the Skywave, not major if it performs well and has good battery life.

Apparently the AR-1780 uses the SiLabs DSP chipset going by comments on Radio Reference. Also has RDS, Temp, the keypad layout looks similar to a Eton G3.

Taken from Jaycar’s website site:

This is a very compact world band radio, covering the most popular frequencies. It features rapid digital tuning, 1000 memory presets, and an easy to read display. Single Sideband Modulation (SSB) is used to listen in on 27MHz CB radio, short wave amateur radio and morse code. The large internal speaker provides clear audio, and you can connect your favourite set of headphones for personal listening. Powerful enough to receive what you want, and compact enough to take wherever you want.

Features:
– FM/MW/SW/LW/AIR Bands
– Single Side Band (SSB)
– Telescopic Antenna
– 3.5mm socket for external antenna
– Selectable Bandwidth: 1 – 6kHz

Specifications:
Radio Bands:
FM 87.5 – 108MHz
MW 522 – 1620kHz / 520 – 1710 kHz
SW 1711 – 29,999kHz
LW 150 – 450kHz
AIR 118 – 137kHz
Batteries: 4 x AA (not included)
Weight: 253g (Excluding Batteries)
Dimensions: 150(W) x 95(H) x 30(D)mm

Many thanks for the tip, Cap!

This looks like a full-featured portable. As mentioned, it certainly resembles the Grundig G3 in many respects.

If the AR-1780 performs well, it’ll be a very welcome addition to the Australia and New Zealand markets.

Please contact me if you’ve purchased the AR-1780 and would like to write a guest post/review. I’m very curious how well this portable stacks up against other portables especially in terms of overall sensitivity/selectivity and noise floor.

RadioWorld: Radio Reaches Blocked Countries

International radio remains the most reliable, robust source of information for people in some nations

North Korea is rated as the second most censored county in the world after Eritrea, according to the Committee to Protect Journalists.

North Koreans who are caught accessing information not approved and disseminated by the government can be sent to brutal prison camps for extended terms, or face execution.

Yet such is the human hunger for reliable outside information, that many North Koreans brave these risks by tuning into international radio and cross-border TV broadcasts wherever practical.

Many also watch banned South Korean TV programs on black market DVDs, SD cards, and USB sticks; plus computers and mobile phones smuggled in from China. (South Korean movies and soap operas are hugely popular in the North, according to the New York Times.)

The conclusions they draw from this content are subsequently shared with other North Koreans by word-of-mouth; despite the fact that such sharers can get in serious trouble with the Kim Jong-Un regime.

Médi 1 Radio may have left the shortwaves

3 Replies

Many thanks to SWLing Post contributor, Paul Walker, who forwarded a message from The Bulgarian DX blog which notes that Médi 1 Radio (Radio Méditerranée) has stopped broadcasting on shortwave:

“MOROCCO According to Jean-Michel Aubier France and a mail sent by Abdellah El-Atmami from transmitting station Nador, Radio Medi 1 (Mediterranee) has stopped shortwaves forever: 24 hours on 9575 NAD 250 kW / 110 deg to NoAf Arabic/French”

I’ll miss Médi 1 Radio on shortwave because they always broadcast a splendid variety of music. Sure, I’ll probably listen to them over WiFi radio, but it’s just not the same–I love the way music sounds over the shortwaves.
