Hi,
I have just one counterpoint to add to this suggestion:
> Better to send less number of parts but say of 20-30Kb size!
Absolutely not. Reason being that there are still folks, in their 60s+
using old TNCS to manually download 7pl messages in software like the
well renouned Paket6.2. Some old TNCs occasionally flip bits, this is
why 7plus has the ERR correction mechanism.
A lengthy download of a 30kb message with 1 stupid bit flipped means
the correction file would also be another 30kb with a risk just as
high for it to happen again.
We cannot ask these OMs to "update their hardware" as many of them are
old, and you may not like this but but as one gets elderly learning
new things is just almost impossible, it just comes with the territory
of getting older. They can't help it. So its not fair to them to tell
them, 'yo man, get a new TNC' or 'yo, update to windows 10 and install
software TNC' because they CAN'T.
The point of 7pl being in small chunks is to allow the messages to
be decoded manually by those who have to, and still do. Do you want
to know how I know? Because I've worked with a great OM who had
difficulty with decoding massive 7plus messages and this is how
I had MY mind changed about it too, because I used to think
'why not!' as well about 30kb 7pl messages.
Have yo uever tried to download a 30kb message over VHF 1K2
and then multiple parts, and still not get a working file?
Frustrating (and it was for him). So... yeah that was a bad idea
You live and you learn!
I am in agreement with PA2SNK as well for this reason.
thanks for coming to my TED talk.
