[digitalradio] Alinco DX70 on 5MHz?

I want to modify my Alinco DX70 for experimental digital transmissions on 5MHz. I have already discovered this: http://www.hampedia.net/alinco/dx-70th-tx-and-rx-mod.php It says that to TX/RX everywhere remove both jumpers c and e, which seems straightforward. However, in my radio, jumper e is

[digitalradio] Re: PSKMail -- Path Tests Revisited

Tony, Thank you for taking the time to perform the tests. My anecdotal evidence is at odd with these results. So the only way I add value to this discussion is to perform the field test in a more controlled way. Thanks again and best 73s, John --- In digitalradio@yahoogroups.com, Tony

[digitalradio] Re: PSK-ROBUST - Path Simulation Results vs field tests

Gary, Thank you for the feedback. Using ARQ systems like you did we have also noticed that faster PSK modes show better performance as in less repeat request than slower ones. Your first theory is the one we believe is the most likely contributor for the ARQ links in general benefiting from
