:-) :-) :-) *Sure* they will. They don't even *listen* on the frequency
before firing up the kilowatts.

Put co-ordinated auto-op frequencies into effect immediately, that should
appease most everyone, hopefully...

W1AW's experience may be a bad omen for the semi-automatic digital stations.
Despite the fact that W1AW only uses one frequency per band, at only certain
hours of the day, using a widely-published schedule that rarely changes,
and has hundreds of users, there has STILL been a fair amount of bitching
and complaining about it.
The digital stations will come on in much greater numbers, at random times
with no published schedules, with only one pair of users per frequency.
(Even if you count each message originator as a "user", it's still less
than W1AW.) I expect the bitch level to be +30 or +40 dB. :=)

Has anyone ever put any version of The Net into a TNC-1??
If not, can anyone tell me why not??

The service manual shows the wiring diagram of the mic. I think they
use a couple of resistors to vary the voltage (or current) fed back
to an A to D to distingush between the various buttons. It's simple,
I just don't recall clearly what it was.

I am looking for a KEYBOARD for a Link Technologies MC-10 terminal. A used
keyboard in good working condition would be fine.
Bought the display at a hamfest but it needs a keyboard.

Why drag our butts? Why settle for a magnitude slower? Why go with 400Mhz?
Sure it was hot stuff in the forties as was 1200 baud 10 years ago. How about
an S-band spread spectrum(direct synthesis) kit. Something that will enable
hams to carry multiple conversations or high speed data streams at once.
Dream a little dream. What would be the requirements? Digitized compressed
video would be one. Perhaps a minimum of 56k data channel. Digitized voice to
be carried over the backbone. Everyone having a personal mailbox or line code
for IRC type comms(with the aforementioned video). Help me out here what else
would the standard need. I just attended a meeting for distance learning over
the internet. Its not there for the majority. We can lead the way. Lets go,
get this big ball rolling.
