Wednesday, July 17th, 2009. Degen 1123.
It is well known that I quietly outgadget my peers, In order to listen to the hypnotic shipping and inshore waters forecasts broadcasted on BBC Radio 4, as well as to amuse myself when away from the whining locals, for the mere sum of 55 dollars I have gotten myself this little pocket radiofrom a reputable seller in Hong-Kong.
The Degen DE1123 covers the range of 522-1710 kHz in longwave, shortwave from 2300 to 23000 kHz, and the FM band from frequencies 87 to 108 MHz. The radio has 225 memories and tunes manually to frequencies by up and down buttons and scanning. It also has a very fast ATS function that tunes automatically every available signal and stores them in memory. The DE1123 has a built-in battery charger for its three Ni-MH rechargeable AAA cells that I soon will change for the best performance of a Lithium-ion battery pack, and a MP3 player, that allows to record broadcasts in WMA files via an integrated microphone which should make the transcription of the forecast ducksoup. The size is a mere 2.7 x 4 x 0.6 inches.
For anyone who may care about it, the radio features can get complicated. It sports both DSP and PLL functions. The former being digital signal processing, a set of digital that convert signals from analog to digital, then manipulate them digitally, to be then converted again to analog form. The latter PLL stands for phase locke loop, and it helps to generate stable frequencies and recover signals from noisy communication channels.
I have shaked it and it looks as if it would work.
Let us see if it can tune from here to the 198 kHz frequency of BBC Radio 4.
