I know that somebody I cannot remember is working on a wrapper for MT63 as layer one. On my tests on 40 meters, seemingly MT63 does not stand the multipath on the lower bands. On 20 it works great. Maybe some Olivia variant could be good with a wrapper for the lower bands. Olivis is rugged, but sloooowww... Nevertheless, my KPC-2 received many packets on 40 m that it could not decode....the LEDs blinked and the TNC output was nil on 40 at 300 bauds. A slow, steady flow is far better than a quicker signalling rate with many failed frames. I see a need for substitute Layer One alternatives. Really, the performance of Layer One established in 1982 sucks, a single failed bit trashes a frame. For some time Pactor and its variants has been a good substitute, but the high costs of the SCS boxes makes them unaffordable for many. Forwarding thruput is 10 times better, and even quasi-QRP operation (25 watts) becomes a workable option. After some time away from packet, I find that activity is inexistent. I don't know if a better Layer One could revive HF forwarding, but certainly, better alternatives are required for FBB and JNOS. I have been a BBS sysop since 1993. I tried a keyboard to keyboard QSO using PAX and it did better than 300 baud packet on 40 meters using Multipsk. I believe that some sort of a driver for FBB and JNOS would be a good thing, both for Windows and Linux....maybe even MSDOS...you don't need much of a computer to run a fairly decent radio only BBS under MSDOS...we have one here in Havana. Possibly many BBS's are doing internet forwarding among them, but that is not an option for many BBS's without an internet link. The revival of HF forwarding would be a good thing on those less fortunate cases. Jose, CO2JA __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
