The first ten transceivers Swan produced were serial numbered from 101-1 to 110-1, with the first nine being model SW-120 operating on 20 meters (14 MHz), and the tenth, 110-1, being the first SW-140, operating on 40 meters (7 MHz). The SW-175 then covered the 75 meter band (3.8 MHz).
175:
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,
202:
Swan also designed a matched, separate receiver and transmitter pair, the 600R and 600T, which together offered better performance, higher output power and many more features than the transceivers could. They were produced in far fewer numbers, however, and are therefore harder for collectors to

In 1969 Swan brought out the slightly smaller model 260 transceiver which could be operated from either 110 V AC or 12 V DC permitting either fixed or mobile operation in one unit. Also named the “Cygnet”, it resembled the earlier Swan 240 but with a different color scheme. It was
191:
Two additional single band transceivers were also made to operate on bands not included in the 350 and 500 but with similar styling and features. A 6-meter (50 MHz) transceiver, the Swan 250, was introduced in 1965, and the Swan 160X was built to cover (not surprisingly) the 160 meter
179:
One of the distinguishing design features of that generation of Swan transceivers was their dual rate, gear-driven tuning dial. A front knob provided slow rate tuning while a metal, outer collar tuned much faster enabling rapid frequency changes across a band. Improved models of the two

KWM-2 was the only other competing transceiver at the time. The operation moved to
Oceanside, California, where, at one point, more than 400 radios per month were being manufactured, and some estimates say that more than 80,000 transceivers were sold during the company's lifetime.

each performed solidly as a basic SSB station. They both used an outboard AC power supply with a built-in speaker, the model 117C and its variants. Improved versions of the 350 and 500 continued to be released into the early 1970s and were Swan’s best selling models.

transceivers were periodically introduced well into the 1970s along with accessories, including a remote VFO (for separate control of receiver and transmitter frequency) and the Mark-I and Mark-II linear amplifiers.

transceivers, Swan introduced the model 240, which covered all three bands in one unit, and then the model 400, which covered five bands (adding 21 and 28 MHz) and had a VFO in a separate unit.
