As such, the Amateur Radio Service is not permitted to engage in satellite operations; however, a sister radio service, called the Amateur Satellite Service, exists which allows satellite operations for the same purposes as the Amateur Radio Service. The philosophy behind band planning is that it assigns frequencies for certain activities in such a way that all current users can practice the various modes of amateur radio with a minimum of mutual interference. UK operation largely follows the conventions shown here but exceptions are common andQSOs on popular frequencies may be found using any mode. Morse operation is centred on 144.050MHz. You can find out the relevant frequencies from National Weather Services website. A few simple rules need to be observed to maintain professional standards of operating on our bands. The transmitted spectrum of an upper sideband signal extends from the suppressed carrier frequency, usually also the indicated or dial frequency, to 3kHz higher, so set the frequency at least 3kHz below the top of the band segment. Its also worth noting that, as you have the ability to tune into any frequency with your gear, you could even listen in to CB or GMRS frequencies with your ham radio. Ham operators seek to exploit the limits of the frequencies usual characteristics looking to learn, understand, and experiment with the possibilities of these enhanced propagation modes. This 25kHz wide sub-band has been made all-modes so it can be shared with the downlinks from new amateur satellite linear transponders.
