Ham Radio Receivers are designed and manufactured in handheld and desktop versions, they differ in many ways offering features and benefits to suit individual needs. A separate receiver covering the Ham Bands you use on a regular basis is a useful addition to any shack because it allows you to monitor your own transmissions.

I would suggest that you to look for a receiver that covers all of the Short Wave bands and many give you coverage of the radio spectrum from the long wave, and through the medium wave band, coverage starts from around 150 Kilohertz through to 30 Megahertz.

New receivers offer the benefit of wide coverage, they incorporate the Very High Frequency spectrum allocation and some continue coverage through the Ultra High Frequency band. V.H.F. and U.H.F. contain special allocations for Radio Hams to use and you will have the advantage of being able to listen to local repeater stations which are designed to extend the range of handheld transceivers.

All mode Ham Radio Receivers are in my opinion an essential requirement, there is nothing more frustrating than finding a transmission that you cannot resolve. Look for a receiver capable of resolving Morse code, and single side band transmissions.

These modes of operation are usually described as C.W. and S.S.B., you need L.S.B. and U.S.B., lower side band is used below 7 megahertz and Upper side band above 7 megahertz. An anomaly in this rule is the 5 megahertz band where Upper side band is used by radio Hams for their transmissions.

Other modes to consider are N.B.F.M, Narrow Band Frequency Modulation is used on ten metres, the upper part of this band especially around 29 decimal six megahertz is used by repeaters. When conditions are good on this band it is possible to listen to radio Hams communicating with fellow enthusiasts between different continents.

Short wave receivers capable of resolving all of the modes of transmission mentioned above can be extended to cover other parts of the radio spectrum, by the use of frequency converters, used in conjunction with the ten metre allocation at 28 Megahertz, frequency converters are available to extend your listening entertainment, many cover the Ham Radio two metre band, located at 144 Megahertz.

Building a frequency converter has additional benefits for the radio enthusiast.

Education is one of them, great satisfaction and a sense of achievement is gained when you build an additional piece of apparatus to extend your hobby. Buying second-hand converters and modifying them to cover other allocations within the radio spectrum, for example the Marine V.H.F. band, it is not only interesting it also adds to your growing knowledge of how radio receivers work.
