Yup, and the reason is that a lot of those guys are deaf! Really..
they dont hear very well, they crank up the volume and then...disaster strikes!

 Nope. Roger-beeps are for lawbreaking CBers and other scum. With proper On-
the-Air skills, this need not happen. SLOW KEY YOUR MIC! Dont assume he's off
the key, wait till he turns it over to you, If he's been keyed-up long enuff
to qualify for a broadcasting award - tell him nicely on the next go round, in
a nice way - like: "Hey Joe, we decided you need a Push-to-Listen switch!"

 Second point: Fixed rotation in nets. Yeah it seems dull, but what's the real
alternative? Buncha people keyed up...noone listening...Lid Net! So to avoid
the "all-together-now" keyup...use a fixed rotation scheme, Im after N6xxx and
then pass it to WA4yyy and so on. All the traffic/MARS nets do it, there must
be a reason!

 Actually, ragchew is just an extended conversation, the exchanges CAN be
brief rapid-fire and not the 10 minute monotone broadcasting that sometimes
try to be called ham radio. I noticed one OF that was exceeding 25 minutes
per keyup on 80m AM..the group just left him after a few go-rounds...poor
feller! Must be a drag...somebody should clue him in!

I am sure that your best bet would be to use a thermistor as the
temperature sensor.  It will give you a large, accurately known,
resistance change with temperature.  The resistance, then, could be
used in an R-C oscillator with predictable and repeatable
frequency-temperature characteristics.

I will leave it to others to advise how you may be able to couple
sufficient power into the circuit from one meter away! :-)

After looking in Part 97, this is the catch all:

    97.105 Control operator duties. - (a) The control operator must
    ensure the immediate proper operation of the station, regardless of the
    type of control.

OK, so you're the control op.  You need to have a method to "ensure the
immediate proper operation of the station."  So, if you want to do it
by carrier pigeon, that's OK, but it has to be "immediate" -- no
time out timers allowed.

: First note that the language of 97.111 actually speaks of "amateur
: stations", not "amateurs".  The way it's been explained to me is that
: this is considered a communication between the amateur station
: autopatching and the repeater, controlled by the control op, who is
: allowing third party traffic over "his" station via the autopatch. I've

Then again, just for the sake of discussion...

This suggests that if the repeater in question had a link to 11 meters
(perish the thought...:) ) then all would be okay???  The one-way
transmissions would be gone and the repeater would complete the
requirement for an amateur station.

Just thought I'd toss that in for thought.
