[FADCA] Transmittal speed

Bob,

Remember that AirMail & WL2K will send all the files in compressed binary
mode.  If you look at the proposal you will see the size for each message in
uncompressed followed by compressed size.  Normally files like word .doc
compress highly. Standard text compresses about 2:1

Yesterday I sent a ham-to-e-mail message with two attachments. One was an MS
Word file (a 30K binary file), the other a small DOS.txt file. The actual
text in the e-mail message was only a reference to the testing. The total
e-mail message was just over 32Kbytes. From my home Airmail set up in
Deltona on 20M I linked with WB5KSD, a frequency/band scanning WL2K station
near Dallas, TX. I got lucky and made the link in about 15 seconds - it
would have taken 45 seconds had I missed his scanning the frequency the
first time. Once linked the entire 32K message was sent and we were
disconnected in about 80 seconds. I then walked across the shack about 10
ft to my XYL's computer and the e-mail message was in her in folder.

Bob: Bud at what baud rate did you pass a 32k file in 80sec? At 1200 baud it
would approximately 9 minutes.
