ok.. I've been messing around with the SE part of the alf circuit, and
think I might have an improvement:
Instead of the pulse generator and the series of diodes to trigger the
latch, why not use a 1381 to start it. The 1381 only uses between 1 and
5 uA during operation, while getting rid of 2 resistors, a capacitor,
and 4 diodes.. as well as freeing up 2 inverters on the 240.. (this is
based on the bivore schematic by Justin Fisher)
I've attached a 2k .gif file of the circuit... Let me know what you
think, as my electronics background is a bit shaky.. I have breadboarded
it, and it *does* work, so it's not just a theory..

2397 Fri, 16 Apr 1999 15:15:45 PDT [alt-beam] Radio Frequencies Beam@corp.sgi.com "Pete McCarthy" Hello List,
The radio AM / FM transmitter message has made me come up with yet
another one of my dull questions. In some e-mail, they stated that
"experimenting is illegal" What frequencies are considered common?
i.e. What frequencies can I use
THANKS IN ADVANCE
-Pete
