This will route it to one of the biggest gateways in the

COMPTON (Reuters) - Police psychologists today were extremely puzzled
as to why a Compton man, identified as Jeffrey Angus, had stopped
northbound traffic on the Santa Ana freeway by running along side
cars only to stare at the crotches of male drivers and passengers.
Witnesses stated he was yelling obscenities and clothed only in a
black basket-weave print belt; a 2-way radio was said to be
clipped to the belt (one ham radio operator who claimed to be
a victim of Angus' staring said that the radio appeared to be
on a frequency of 147.435 MHz - this could not be confirmed).

It certainly will make a difference if it is only several hundred volts. It
will be like a direct short soon. An electric fence puts out thousands of
volts.

Subject: frg-8800 stops operation after short time
To: info-hams@ucsd.edu
My frg-8800 showed this problem a few months after I buyed it when
I was using a MIF-90 to tune quite fast through the frequencies:
At some time (30secs to few minutes) it stopped audio output. I then
stopped this computerized tuning and used it as normal receiver. Now
(lots of years later) the frq shows this behavior during normal operation:
turn it on, tune throuhg a few frequencies, and autio output stops.
The failure seems to be progressive: now I need to turn it of for a
while, and then I'm able to use it for a short period of time (<2 min)
and then the problem reoccurs...
Any ideas?

The entire morse test is multiple-guess! There is *no* relation
to anything real in the morse test. No smoke, no fire, no screaming
sailors, nothing.
Seriously, I was astounded at the low level of comprehension
required in the 13-wpm test I took. I had slaved for a month to be
sure I could tell "FT-100" from "FT-101" in the middle of a qso.
Then I take the test and the questions are "Rig is: A: Yaesu B:
Icom C: Kenwood D: Heathkit."
Of course you should be allowed to use your keyboard. Sheesh.

That's right it has two good side effects.
1) It keeps the collect mind of the nation off the health care and White
Water debaucles.
2) It might lead to Radio Control (tm) becoming one of the leading
national problems as shown in a future Gallop poll.

### larger.
How it works:
The 2 tubes form a push pull power oscillator which makes alternating
current, but at a radio frequency.
This is done by use of L1 , L3, and the 2 little tubes.
In this case, the actual frequency is not important, sence the objective
is to generate maximum bandwidth...the goal of any 'phone station.
C1 is used to obtain maximum power by resonating L1 to L2's natural freq.
This RF voltage is stepped up by a factor of 30 to 100X by L2 and sent on
to the spark-gap, where the actual RF-to-be-sent is generated.
The RFC keeps the ant ckt at DC ground, yet will not short out the RF...which
is sent from the sparkgap, to the ant.
The ant wants to be one wire, and end fed. No coax required..just hook 'er
up and duck.
The length of the antenna determines the sending band it will be on.
The formula to use to get that length is...
Feet = (468/(((F*F) +730 ) -(F*F))) *35.5
F = frequency in Mhz ( rounded off to nearest 100 Khz )
Voice modulation is done by use of a special Carbon Microphone, as used in
the 1920's...which can handle several amps.
Here, rather than sending RF thru the mic as was done back then, only DC
is sent thru.
That way, the operator (or inflictor) won't get an RF burn on his lips if
he speaks too close to the mic.
That modulates the power to the tubes , which varies the intensity of the
spark which then puts quite suitable a signal on the air.
The intellegibility will match the content of some of the QSO's now on the air.
To operate:
1 Place mouth near carbon microphone.
2 Close S1 and adjust C1 for dip in current (mtr) quickly.
3 Make oinking and Mooing noises to indicate your presence to everyone.
4 Open S1 when you get around to it.
