Come on, Steve!

145.800-146.000 is the International Satellite sub-band.  It needs to be 
accessible by amateurs in Region 1, which does not have access to anything 
above 146.000, and it shouldn't interfere with other satellites and/or 
services.

I don't see how such a thing could be done.  The Icom 725 seems
to be a no-frills rig, and the prices recently for a new one
came down to about $750.  I don't think an all-band HF rig with
2 VFOs has EVER sold for as low as $400, not even in the good-ol days.
I saw an ad for a Drake TR-4 from the early 70's that sold for $600
new.

Hi Robert,
   Don't forget to COMPRESS and UUENCODE your battery first!

For the rest of you ..
   How to stop your battery discharging on concrete:

1: Rip all those nasty ol' PL259 bconnectors from your VHF/UHF
   equipment. Use them as standoffs between the battery and the
   concrete.
   NOTE: If you already have nice piece of wood to protect your
   battery from discharge, you could send all your unwanted PL-
   259's to Craig Shergold instead.

2: Pile up all your Craig Shergold chain letters on the concrete
   and put the battery on top.

3: Hang the battery from the ceiling with a piece of 9913 cable.

Any other suggestions?

Simon Woodworth.

Well, then, as long as you use the same spot, the second battery you placed
on it should be allright, no?

Probably indefinitely, as long as he keeps changing hands :-) Speaking
as a member of WICEN (Wireless Institute Civil Emergency Network - a quare
name but great stuff :-), which is the Australian counterpart I guess of
ARES and RACES, these sort of stupid comments come from silly old farts
who wouldn't recognise an emergency if they were sitting at the epicentre.
On the other hand, he could be a frustrated CBer who's got one too many
RF burns from sucking on the whip while transmitting :-)

I don't know about you guys clinging to the bottom of the earth, but
WICEN is taken very seriously by the emergency services up here - we're
also a member squad of the largest all-volunteer rescue service in the
world... no cofee and doughnut ops here either :-)

yes you can run the radio off the car power.  it's just the connector polarity
that's weird - you still have a negative ground car.
 
nope, there seem to be an large number of combinations of these things:
 
        polarity (some equipment is center positive, others center negative)
        diameter of pin (several sizes)
        diameter of plug (several sizes)
        barrel length of connector (several lengths)
 
and it seems like they make a new one for every new model of new product...
don't want to be able to use a Sony charger on a Panasonic VTR or a Yaesu 
HT with an Icom car power cord. (makes one feel lucky that at least they don't 
put a different connector on every different model of radio - not that they 
don't try).
 
radio shack sells kits with different size plugs that mate to another
connector that permits you to select polarity....

This is because concrete has had all the karma processed out of it.
Therefore, it will absorb all the vibrations from the battery.  If you
use a good hardwood, it will even charge your battery up for you,
because of all the good emanations coming from the wood.

I believe that there *is* a service (called something like Tele-Check)
that does guarantee payment if you run the checks through them for

When Gloria hit Connecticut a few years back (minor damage compared to
what just happened in FL and AL) our telephone service stayed working
just fine. Just up the street from me was a sight to make Ma Bell proud --
a 3'-wide oak tree had toppled onto the utility lines. The electric lines
had snapped like string. The massive tree was stopped by the lower telephone
line, bent down about three feet, but still working. Two poles up, one
of the poles had been knocked to the ground by another monster oak. The
electric and telephone lines were laying on the ground. The drop line to
the house had pulled away from the house, leaving the house without
telephone service. On a whim, the owner ran some zip cord from the house 
telephone wires to the ends of the severed cable -- service was
restored!

Perhaps there is truth in the myth. Concrete floors tend to get cold in winter.
Lead acid batteries do not work well when cold. Therefore placing a battery on a
concrete surface outside may cause it to loose capacity. Especially true for
battery systems not designed for cold weather use.

One case where I use PL259s on 9913 is when connecting to an antenna which has
an SO239 connector. It doesn't seem like the impedence bump is going to be any
worse using the PL259 versus using an N connector and an adapter.

In my particular case I have this configuration at 6 meters on a ringo, and on
a diamond X200. While I would prefer antenna manufacturers use N connectors, 
this is not reality, so I compensate.

I edit a ham club newletter and would like to print an article on how the  
term "ham" came to be a nickname for an amateur radio operator

To save space on this group you may respond to me directly at...

               derry@nextwork.rose-hulman.edu

I seem to remember reading about this several years ago in a ham radio  
magazine.

tnx es 73 de Jack, K9CUN

Large topic. Hopping is generally lumped in with other spread spectrum
methods, though there are different advantages and disadvantages with
hopping than with direct sequence spreading. Burst is a different system
completely. If the hopper's hop rate is faster than the symbol rate,
many of the same advantages of PN spreading are obtained while placing
higher instantaneous power on the current channel. Hopping, particularly
slow hopping, is also often easy to implement by modifying existing narrow 
band equipment. 

Basically, hoppers take a narrow modulated carrier and rapidly change it's
center frequency. So at any given frequency you have a full power signal
present occasionally for a very brief period. 

Pseudo-noise direct sequence spreaders work differently. The carrier is
fixed in frequency, but is modulated very broadly by a PN sequence that
is XORed with the data symbols. Again, you want the PN modulation to be
at a much higher rate than the symbol rate. Since the power of the carrier
is spread widely across many channels, any given channel has very little
signal power present. Since the power is correlated, it can be despread
in the receiver and recovered.

Burst is simply a narrow modulated carrier using a very high data rate
to transfer the message in a very brief time.

Various experts will probably correct the sloppy explainations above.
