Digitech PLL World Band Radio

Batteries IncludedA PLL world band radio loaded with a great list of features but easy to operate. Select from 5 available bands, FM, AM(MW, with 9k or 10k step), SW, LW and AIR bands. Tune to a desired frequency using the fast or slow scroll function and store up to 500 of your favourite radio stations. Features:• 500 programmable memory bank• Sleep function up to 120 minutes• Manual, auto, or preset station search• Battery indicator• Includes carry case• Lock button• AM(MW coverage: 522 - 1620 kHz(9k) 520 - 1710 kHz(10k)• FM coverage: 87.5 - 108.0MHz• SW coverage: 2300 - 26100 kHz• LW coverage: 153 - 279kHz• AIR coverage: 118 - 137MHzNote: Most AM broadcasting services in Australia use the medium frequency (MF or MW) band and occupy the frequency range between 526.5kHz and 1606.5kHz, with each channel designated by its carrier frequency. The standard channel spacing is in Australia is 9kHz. There are also many AM radio stations above the standard AM broadcast frequency range which the AR-1733 will allow you to tune into. To change the AM tuning band from 522-1620kHz to 520-1710kHz on the AR-1733, firstly make sure the Radio is Off ie time displayed. Press and hold the channel spacing 9/10kHz button until the display reads MW 10kHz. This changes the AM tuning band to 520-1710kHz with 10kHz spacing. You can now enter the exact station frequency ie 1683kHz by pressing the FREQ button, then the AM frequency by using the keypad 1, 6, 8, and 3. Pressing the 9/10kHz button again will change it back to the standard 522-1620kHz with 9kHz spacing.  For More info on World Band Radios. HandyTip What is World Band?World Band Radios are those radios that are capable of tuning into radio programs generated by, say the British BBC, Radio Australia(Australian ABC Radio programs), Voice of America, Radio Vatican, etc. These programs are transmitted on a regular weekly basis in any one 24 hour period. It is generally preferable to use 24 hour time, linked to GMT (Greenwich Mean Time) which is the time it is in London (UK) so that confusion is eliminated as when the program is broadcast. There are dozens and dozens of programs from countries all over the world in the special languages of these countries. For example if you are an Australian citizen but originally from Greece, you can tune into stations that enable you to keep your knowledge of the language up to date. The stations typically have a lot of local news which you would normally not hear. The World Band stations are generally broadcast in several frequencies at the same time, typically between about 1.8MHz & 29.00 MHz, especially between7 & 21MHz. You can look up the broadcasting details on Google etc. Phase-Locked Loop (PLL) is a circuit configuration invented over 80 years ago. Originally the circuit was so complex that it only appeared in expensive radios. With modern microchip technology, the PLL got a lot cheaper. The benefits of PLL technology enabled receivers to remain on a station frequency with great accuracy. The radio circuit did not ‘drift.’ PLL technology, though still not cheap, is a hallmark of quality short wave radios and that’s why Jaycar specifies them.
