Rik, Very interesting on the three types of spectra: So far I 'played' with 3 types of modulation : real BPSK, PSK (amplitudes enveloped) and what I call 'soft' PSK (gradual phase transitions instead

This can be done by phase-shifting the RF signal by 910 degrees must be 90 degrees of course Rik ON7YD

In an attempt to compare the different PSK-like modes I built a kind of 'universal modulator' that could generate a PSK signal, BPSK signal and all variations of these. Such a modulator must be able

Dear LF Group, Regarding the bandwidth occupied by BPSK - John, KD4IDY has kindly posted the spectra I obtained recently for various types of BPSK and phase modulation on the LWCA web site at http://
