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.
As an "all-band" transceiver, the TS-2000 offers a maximum power output of 100 watts on the HF, 6 meters, and 2 meters bands, 50 watts on 70 centimeters, and, with the TS-2000X or the optional UT-20, 10 watts on the 1.2 GHz or 23 centimeters band. The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz ...
This list does not include handheld, portable or consumer grade equipment. Those that include VHF or UHF can be termed wideband receivers, whereas those without HF would be termed scanners, or surveillance receivers. Receivers without controls, that are operated or implemented in computers are in the list of software-defined radios.
The ML-2 “Marker Luxury” was a crystal controlled FM transceiver for the 2-meter (144 MHz) band. The TR-22, TR-22C, and TR-33 were very small 2-meter FM transceivers that were entirely self-contained, including a telescoping antenna and rechargeable battery. They each came with a microphone and carrying case with shoulder strap.
Automatic Link Establishment, commonly known as ALE, is the worldwide de facto standard for digitally initiating and sustaining HF radio communications. [1] ALE is a feature in an HF communications radio transceiver system that enables the radio station to make contact, or initiate a circuit, between itself and another HF radio station or network of stations.

An amateur radio station incorporating two HF transceivers. A typical Yagi antenna used by a Canadian radio amateur for long distance communication Boeing 707 used a HF antenna mounted on top of the tail fin [8] The main uses of the high frequency spectrum are: Military and governmental communication systems; Aviation air-to-ground communications
In addition, the FCC continues to require that all digital transmissions be centred on the channel-centre frequencies, which the Report and Order defines as being 1.5 kHz above the suppressed carrier frequency of a transceiver operated in the upper side-band (USB) mode. As amateur radio equipment displays the carrier frequency, it is important ...
