Hopefully people took time to read this announcement, it represents a major advancement. Of course, now I am interested in some mode-independent application for when not passing mail. The PSK500, PSK500R, PSK250, MFSK32, THOR22, MFSK16 and THOR8 shifting looks like a good method Andy K3UK

I did not follow the whole conversation. Anyway, spread spectrum has following benefits as far as I am known: It allows more stations to use the spectrum. The trick is in spreading the signal by a sequence, which appears to be random. Many stations transmitting spread spectrum signals at

Vojtech I think you will find that SS could make monitoring the bands more difficult as SS rings bells of the cryptographic sort in odd places .. and as these bell ringers are still trying to decode enigma and ultra intercepts from ww2 ... meetings in forests and the like ring any

The FCC has addressed the cryptographic aspects of spread spectrum. Only certain relatively short PN codes are permitted for spread spectrum operation in the currently authorized bands. It is relatively trivial to cycle through those codes and receive the signal. The downside is that the
