In the ITU Table of Frequency Allocations, no formal allocation to any radio service is present above 275 GHz, although the regulations themselves cover up to 3,000 GHz (3 THz). However, a number of administrations permit amateur radio experimentation within the 275–3,000 GHz range on a national basis, under license conditions that are ...
The 6 metre amateur band falls into this category, often called "the magic band", will often "open up" from one small area into another small geographic area 1 000–1 700 km (600–1 000 miles) away during the spring and early summer months. This phenomenon occurs during the fall months, although not as often.

Later, in the mid-1960s, Swan introduced the more full-featured models 350 and 500 transceivers. The Swan 500 was a more costly version of the 350, with higher output power and more operating features. Although they lacked the higher selectivity and tuning accuracy of higher priced transceivers, each performed solidly as a basic SSB station.
