RE: 300bps Packet (and EHAS) - what is pam, psk, and newpsk,

Are you the Tomi Manninen who implemented the NEWQPSK protocol to the soundmodem?
If so, I wish to hear technical comments on the efforts of EHAS program to improve the codes developed by the Tomi described in the following article titled "Low cost E-mail over HF with OFDM and turbo coding techniques". http://download.ehas.org/misc/articulo_HF.pdf
Yes, back when Arnau was developing this, we did some co-operation. At the time Arnau contacted me, I had already done some experiments in improving the framing and FEC. Arnau did a great job implementing Turbo, soft decision sampling etc. Unfortunately I never had time nor anyone to test it with on ham bands (Arnau is not a ham and the general interest on newqpsk and packet had already declined here). But I think the code is available on a SVN server at EHAS. /Tomi, oh2bns -- To unsubscribe from this list: send the line "unsubscribe linux-hams" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
