SuperStar 3900 frequencies?

It is far too common to refer to a broadcast band by the modulation method used rather than the band of frequencies used. Here in the UK we refer to those radio broadcast bands as "MW" (Medium Wave) and "VHF" (Very High Frequency). These bands are also commonly referred to as "AM" and "FM" simply because the MW band uses Amplitude Modulation and the VHF band uses Frequency Modulation. We also have a band called "LW" (Long Wave), which also uses AM. Regardless of the wave length, you can transmit an AM, FM, SSB or CW signal. As long as the law permits it :~) Our MW and LW bands are both used with AM, our VHF band uses FM. Technically it is possible to use any mode on the frequencies, but not legally. Because such bands are always used with AM or FM, they often get referred to by the mode used... which can be misleading. We are only allowed AM and SSB on 11 meters in the US, but many so called export radios have FM though rarely used and cw mode for the supposed 10 meter radios that hams would never buy and easily convert to cover 10, 11, and 12 meters. MW, LW and VHF are just different frequencies. Bands of frequencies. I worded it wrong, but thats what I meant to say. I don't know how many people in the UK still listen to MW or LW when VHF broadcasts, using FM, provide much clearer audio and stereo broadcasts. There are always holdouts on dying modes of communications. The "CW vs. no CW test" war is raging on in the US as an example. Regards, Peter. Cheers! |
