• Notes

• The Swan 175 is the 75 meter version of a series of three amateur band SSB transceivers known as "mono-banders" because of their single band design. RF input is rated at 240 watts P.E.P. using a 6DQ5 tube. Other tranceivers in the series are the 120 and the 140 designed for 20 and 40 meters respectively. Like most monobanders, an external power supply is used since the unit could then also be used in mobile applications. The manual for the 175 gives instructions for modifying a Heathkit HP-20 power supply to match the Swan. The weight shown does not include a power supply.
