Sain juuri vastauksen WOR 710:ltä (alla). V/s kertoo aseman testanneen digitaalilähetyksiä, jonka vuoksi kaistanlevys on kapeampi ja kuuluvuus täälläpäin parempi. Mutta onko kenelläkään tietoa AM-asemien siirtymisestä (steereo)digitaalilähetyksiin? Ensimmäiset radiot tulevat kuulema markkinoille tänä kesänä. Jäävätkö jenkit kohta vain muistoksi menneiltä vuosilta ja tasaataajuuksilla kuulemme vain kohinaa? Utelee.

Yes, you have in fact DX 'd WOR-AM. For the past several months we have been testing a new Digital transmission scheme by Ibiquity. This has reduced our analog bandwidth to 5khz, therefore we are much louder on the dial and now get out farther, which ends up helping far away listeners like yourself.We frequently get reports from the UK and as far away as Russia. This is due to the WOR directional antenna, which pushes about 250kw ERP, into the Atlantic Ocean and beyond. Our antenna is designed to cover the US eastern seaboard, and your reception is a by-product of the design of our antenna. With the internet, DX'ing is now becoming almost a thing of the past, and with the US getting into an In Band On Channel (IBOC) digita transmission scheme for AM broadcasters, you may have even more difficulty getting a lot of US stations. Right now we are not operating this system at night but we expect IBOC will eventually be on at night . There are digital carriers on each side of the analog signal, and sound like white noise, and presently go off at sunset and on at sunrise NY local time. Time will tell on this one. The new HD radio's will be out here in the US this summer, we are excited about it because it allows us to deliver a stereo digital signal to our listeners. The new radios we have tested make WOR sound like FM. You can keep in touch via our website www.wor710.com, thanks for your interest in WOR.
