Steve, 1. With your experience with the MIL-STD-188 serial tone modems on HF, what is your assessment as to their performance under various conditions compared with other modes?
2. Our Section terminated a Pactor I BBS system and moved the equipment from amateur radio to the SHARES program where they do use this mode but I believe they have a dedicated frequency for digital operation. 3. If MARS and SHARES are moving toward ALE, they must find this mode to work the best. Have you found ALE to be a pretty good mode for message traffic, documents? How does it compare to other modes? Any downside? 73, Rick, KV9U Steve Hajducek wrote: >Hi Walt, > >SHARES, is VOICE, PACTOR I and ALE AMD at this time. > >MARS is using just about every FEC/ARQ protocol common in the U.S. In >MARS CW, it long ago was obsoleted.
