QRPguys DSB rigs for digital modes

Practical Wireless has a piece on a tiny, low cost, DSB rig kit that is ideal for digital modes like FT8. The article is written by Martin Peters G4EFE.

This is a QRP transceiver producing the equivalent of 500mW at least of SSB. On digital modes like FT8, this is capable of worldwide QSOs.

Being DSB, half the power is wasted, but this makes the rig very simple. On WSPR it would be even better, although there are far more people using FT8 than WSPR.

    Doesn't DSB use twice the necessary bandwidth in an already crowded segment of the band?
