[digitalradio] The ARQ Advantage?

All, It would seem that ARQ modes would have some advantage on a disturbed HF channel since the data is checked and repeated in an attempt to achieve error-free throughput. In theory, the non-ARQ mode will lose data when the channel fades below threshold where the ARQ mode should detect the

Re: [digitalradio] The ARQ Advantage?

Hello, Tony! The advantage you mention for ARQ modes is in fact their primary drawback in the environment we inhabit as amateur radio operators, which is shared spectrum. In commercial or government channelized spectrum, ARQ does in fact have some edge. Our amateur radio HF spectrum however,

Ah, AX.25 is an ARQ mode. How is it different from other ARQ modes vis-a-vis "evaluation"? - 73 - Rud Merriam K5RUD ARES AEC Montgomery County, TX http://TheHamNetwork.net -Original Message- From: Charles Brabham [mailto:n5...@uspacket.org] Sent: Thursda

Re: [digitalradio] The ARQ Advantage?

Howdy, Rud! AX25 allows several stations to operate within a bit of spectrum wide enough for one. For example, up to a dozen Q15x25 stations can operate within one 1k to 3k ( depending on how you scale the modems ) slice of spectrum. ARQ modes that do not operate under AX25 are incapable of th
