How high does this 'stick' put your antenna? If your not concerned with
getting it over the roof line then you should be able to find a way to
disguise it some how. Do you have a balcony or are you just sticking it
out the window? If your on a balcony, you should be able to hang a potted
plant ( live or fake ) and 'grow' the antenna out of that. Or set you up a
permant flag pole for one of those small, US flags or wind-socks. Use that
as the antenna or figure out a way to attach the antenna to that at night.
See if you have any vent pipes on the roof near your window. If so, you
might be able to get the manager to let you put up one of those Vent
Antennas. It slips right over the pipe. If you want to find a way to
'force' them to let you use your antenna, your out of luck. If you signed
the lease that said no antennas, then you have to live with that or find a
way to disguise the antenna.

MIDDLE LATITUDE AURORAL ACTIVITY WARNING
WARNING ISSUED: 12:30 UT, 04 NOVEMBER
/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
VALID UNTIL: 19:00 UTC ON 06 NOVEMBER
HIGH RISK PERIOD: 04 Nov - 05 Nov (UT days)
MODERATE RISK PERIOD: 04 Nov - 06 Nov
PREDICTED ACTIVITY INDICES FOR NEXT 4 DAYS: 55, 30, 20, 12 (04 - 07 NOV)
(INPUT INTO THE AURORAL SIMULATION SOFTWARE *)
POTENTIAL MAGNITUDE OF MIDDLE LATITUDE AURORAL ACTIVITY: MODERATE - HIGH
POTENTIAL DURATION OF THIS ACTIVITY: 48 TO 72 HOURS
POTENTIAL LUNAR INTERFERENCE: LOW - MODERATE
OVERALL OPPORTUNITY FOR OBSERVATIONS FROM MIDDLE LATITUDES: FAIR - GOOD
APPROXIMATE OPTIMUM OBSERVING CONDITIONS (LOCAL TIME): PRIOR TO 9 OR 10 PM
AURORAL ACTIVITY MAY BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...
WASHINGTON STATE TO NORTH-CENTRAL IDAHO TO NORTHERN WYOMING TO
NORTHERN NEBRASKA OR SOUTHERN SOUTH DAKOTA TO IOWA TO NORTHERN
ILLINOIS OR SOUTHERN MINNESOTA TO SOUTHERN WISCONSIN TO SOUTHERN
MICHIGAN TO NEW JERSEY. THERE IS ALSO A CHANCE POINTS SOUTH OF THIS
LINE MAY ALSO SPOT PERIODS OF ACTIVITY.
ACTIVITY MAY ALSO BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...
THE U.K. TO NORTHERN GERMANY AND DENMARK TO NORTHERN RUSSIA,
INCLUDING MOST OF NORWAY, SWEDEN, AND FINLAND. EXTREME SOUTHERN
REGIONS OF AUSTRALIA AND NEW ZEALAND MAY ALSO BE ABLE TO SPOT
ACTIVITY DURING THE WARNING PERIOD.
* Contact: Oler@Rho.Uleth.CA or COler@Solar.Stanford.Edu for more information
regarding the Auroral Activity Prediction and Simulation Software.
SYNOPSIS...
Auroral activity has increased substantially over the last 12 hours.
Minor to major auroral storming has been observed over the upper-middle
and high latitude regions. Conditions are expected to remain at these
enhanced (and perhaps stronger) levels over the next 24 to 36 hours.
Observing conditions during this time will be good prior to moonrise
which occurs between approximately 9 and 10 pm local time. Thereafter,
moderate lunar interference (a 68% illuminated moon) will degrade
observations from dark-sky sites.
For those with our Auroral Oval Simulation Software, optimal input
values of between 40 and 60 should be used on 04 November, changing to
values between approximately 25 and 40 on 05 November. Use the Internet
command: "finger aurora@xi.uleth.ca" to obtain current forecast values
and synoptical information.
This warning will remain active until 19:00 UT on 06 November when it
will either be updated or allowed to expire.

I don't think your 2nd method will work with the typical SWR meter
that Joe Ham has. Look at it this way: if I hook a 100 ohm resistor
directly on the antenna terminal of my 50 ohm SWR bridge, I will
see a 2:1 SWR indication. If I hook a piece of 100 ohm coax to the
antenna terminal, with a 100 ohm resistor on the far end, the SWR on the
coax will be 1:1, but my 50 ohm swr bridge will still indicate 2:1,
because it still "sees" a 100 ohm resistor on its output.
That's why the meter has a characteristic impedance.
Now if your "SWR meter" is actually a time-domain reflectometer,
you *can* use such a technique, just tune until relections disappear.
TDRs are *almost* as expensive as network analyzers though...
Probably the cheapest and most reliable method is to read the numbers
stamped on the side of the coax, and look them up in a reference book..

Hi!
My friend, Bill, needs some info. Here's his problem:
I am builing a keyer circuit using the Curtis Keyer chip
I'm trying to reduce the size and power consumption so I
would like to use an optoisolator instead of a relay or
transistor type circuit for the output stage. My rig is
a Kenwood TS-140S. I'm interested in circuits that use
opto isolators and which components use the least amount
of power. Any suggestions?
Thanks and 73,

Chris,
Yes, the Outgoing Service DOES forward cards to Cuba (CO). And yes,
there does exist an Incoming QSL Bureau for Cuba.
The only time you should use a QSL Manager (for Cuba) would be
if the amateur you QSO'ed with requested you QSL via a Manager.
The Cuba QSL Bureau also forwards cards to the U.S.. These cards
come directly to us here in the Service. Once received, they`re
sorted, and mailed out to the various U.S. Incoming QSL Bureaus.
You have to realize though, that mail INTO Cuba goes through a
number of mail inspections, is re-routed though Miami, and so
forth. Mail INTO this country (from Cuba) goes through nearly
the same machinations. So unless QSL cards are mailed direct, cards
sent through the Cuba Bureau system take awhile to get to their
proper destinations.
I'd recommend QSLing direct only if you REALLY need the card (i.e.,
DXCC, WAZ, WAC, etc.)
Hope this helps!

This is NOT a CW-only phenomena, either... I listened to a QSO between
a station in Rhowanda and a WB5xxx (no need to pick on anyone by name,
he'll know who he is...) hoping I could sneak in for a signal report
and a few words with a rare African station from my mobile.
After a few rude souls broke for signal reports (the African wanted to
chat, not run a pileup) the Rhowandan announced for all to hear "I do
not like these pileups, I am going QRT." and shut down... one "1"-land
wonder actually carried on what he thought was a QSO, although it was
in his head and in the ether, including asking for a repeat of his
signal report... then, slightly embarrassed when someone pointed out
to him that he had QSO'ed himself, he announces to the whole world "I
guess I was hearing what I wanted to hear. I don't know who I just
worked, but I hope he'll QSL." 100% via buro om ;^)

Hello:
I just managed to snag the good deal on the TS 430 over on rec.radio.swap
and wondered about the 430 as a mobile rig. I have not used one.
How sensitive is the final to SWR? How effective is the noise blanker?
Does the 430 need an external speaker?
How useful is the mobile mounting bracket?
I will probably mount it in
my new (old) VW van which I want to make into a fine radio-mobile :-).
Any hints and suggestions appreciated.

I thing one of the TOP TEN "big ham radio lies" is that you can work an
orbiting object with an HT. OSCAR 21 is supposedly one such satelite
and from my experience you need several dozen watts and a yagi which can
be pointed at the "bird" as it fly overhead.
Verticals have too low an angle of radiation to work a satelite which is
higher than 30 degree or so above the horizon.
On the bright side, you can HEAR many of these satelites with even a
cheap scanner. Try it!

No. It's very much like saying "trees." Take a look at V.32, for
example. Take a look at ETSI DTR/TM-3017.
There are some words that are both singular and plural. Baud is
not one of them. Bauds is the one word to have when you're having
