The project consists of 5 vacuum tubes without ICs or transistors for making a true SSB QRP transceiver for 20m Ham band. The project consists of 5 vacuum tubes without ICs or transistors for making a ...

There was a time when the idea of building your own single-sideband transceiver was too daunting for all but the most hardcore of amateur radio constructors. After all the process of creating SSB is ...

Can you build a HF SSB radio transciever in one weekend, while on the road, at parts from a swap meet? I can, but apparently not without setting something on fire. Of course the swap meet I’m ...

The circuit has been designed to produce a transceiver that switches the 4-element 1500 Ohm external BPF ends between the inputs and outputs of the two SA602s to reverse the signal flow for R/T ...

RFDN03C (DNC Mixer) is IR SSB Mixer used in transceiver application. The process used to design DNC Mixer is 0.1um GaAs pHEMT. This Mixer employs two ...
