ATS-25 is a battery-powered broadband receiver SSB (LSB and USB) / AM / FM based on SI4735/32 (version 5.2b) operating in the following bands: LW: 150 kHz - 510 kHz SW: 520 kHz - 1720 kHz KF: 1.720 MHz - 3.500 MHz 3.500 MHz - 4.500 MHz 4.500 MHz -5.500 MHz 5.500 MHz - 6.300 MHz 6.300 MHz -7.800 MHz 7.800 MHz - 10.000 MHz 10.000 MHz -11.000 MHz 11.000 MHz - 12.500 MHz 12.500 MHz -13.900 MHz 13.900 MHz - 14.500 MHz 14.500 MHz -15.900 MHz 15.900 MHz - 17.900 MHz 17.900 MHz -18.300 MHz 18.300 MHz - 21.900 MHz 21.990 MHz -26.200 MHz 26.200 MHz - 27.900 MHz (CB band) 27.900 MHz -30.000 MHz 1.800 - 30.000 MHz (full range KF) FM: 76-108 MHz (FM mono and stereo) The receiver covers the entire KF band from 1.720 MHz to 30.00 MHz, the long wave band from 150 to 510 kHz and the medium band from 520 kHz to 1720 kHz. The receiver works great on short waves with regular antennas, which you can see on the following video materials (receiver connected to a full-size Delta antenna according to SP7LA): {youtube}M6Hgx93mleA6004500{/youtube} The receiver is equipped with a BFO with a step of 25 Hz, five filters with a bandwidth: 0.5, 1, 1.2, 2.2, 3 and 4 kHz and three tuning steps: 1, 5 and 10 kHz Light weight and dimensions make the SI4732 receiver an ideal solution for any trips for which we can not take a full-size radio and do not want to lose contact with the radio. The headphone jack allows you to listen za headphones (Jack 3.5 mm).
