[GreenKeys] New Loop Converter Prelim specs

[gil smith]

Hi folks:

Thanks for all your input so far.
Some notes from the feedback:

- full duplex should maybe stay

- external loop supply needed by some (connectors are up to you)

- buffers will overrun on solid streams (yup -- but can't hurt)

- maybe add optional tx diddle insertion (insert ltrs/figs idle chars)

- maybe add optional rx diddle filter (remove excess ltrs/figs)

- relay drivers and lights on DTR and RTS (keying or whatever)

- regen needed for some TUs (how does this work?)

- does anyone have a TU with MIL 188 (+/-5) and not 232?

- Nobody seemed to care about storing and replaying test messages or
answerback strings.  But what about a test message to the local tty loop
with a programmable amount of distortion?  Tell me how these test sets
inject distortion.

-Question on the issue of SelCal auto-powering of TTY motors:
If you auto on/off with ZCZC and NNNN and if you are dealing with alot of
traffic, wouldn't that tend to cycle too much?  Would there be a difference
based on 60/100wpm?
My uninformed response:  I dunno -- the radio side of things is not my
area.  I suppose there could be some delays enforced;  eg: after NNNN, wait
X seconds or minutes before powering off.

feedback always appreciated,

gil
