Re: QRPGuys DSB Digital Transceiver

Larry Lovell All Messages By This Member #19745 Adam Rong (BD6CR) wrote this in his manual for his D4D/FT8 kit: "Do we have to worry about the unwanted Lower Side Band (LSB) and Inter-Modulation Distortion (IMD)? Maybe, but for a transmitter of 1-watt, it is not really a big problem for occasional field, SOTA or experimental purposes. Is it just a toy for a transmitter of 1-watt and only half of the effective power? Not really, as I can easily make a few QSO’s as far as 1500 miles range even for 40-meter band when the propagation opens." toggle quoted message Show quoted text On Sun, Nov 3, 2019 at 3:47 PM Randy.AB9GO <randy.ab9go@...> wrote: With all the controversy surrounding this kit I am sorry I even purchased it. It's sitting here waiting to be assembled. I suppose I'll throw the PCB boards away and keep the parts for future projects. With so many problems surrounding dsb (other than simplicity) I cannot understand why the qrpguys put this kit out. In retrospect I would have paid extra just to have a proper SSB signal after reading all the comments in this thread. Randy AB9GO -- Larry Lovell 73's N7RGW <> Cell: 214-697-1729
