 is it in the Canadian exam?  If so, at what level ??

Hi

I have purchased a cheap SWR meter from a rally,  how do I go about

Try repeating the word MAYDAY ("m'aider") three times and then stating
the nature of the emergency.  Only an idiot would insist on call letters
before helping you.  You still might run into such an idiot who makes you
debate the issue, though I can't think of any magic words to avoid that.

It's against regs, and probably a crime, to do this falsely.

You are thinking of the ARRL Automated Electronic Mail Server,

body of the message:

help

We don't have an FTP server running, yet, and we probably won't include
many of our files when we do. Our current connection speed is compressed
9600 baud, so FTPing a large file would be SLOW!

We have nearly all of files available from world.std.com, so if you
want to FTP them at real network speeds, get them from there.

I'd like to get info about amateur radio clubs in and around the Pittsburgh
area (contact person/phone/address).  also info as to what areas of
interest
each ARC caters to, what repeaters they operate, fees, benefits, etc.

will a (2 to 5watt) HT (using a different antenna other than the stock
rubber
dummy) be sufficient to use in the hilly terrain of the Pittsburgh area for
home and mobile use ?

please email replies if possible.
thanks in advance

So tell me, does the FCC recycle?

At one time, I was KA9PGU.  Well, because of financial problems (I was
13 and my folks weren't into it, etc, etc, etc) I had to let my ticket
expire.  (To avoid flames, Yup, I could have renewed, but I didn't...)

Ok, now KA9PGU is 'sitting idle.'  At least as far as I can tell.
I know of at least 10 other people who aren't using their calls for various
reasons (and they probably won't.)

So, my question is: can't the FCC re-assign said call to new hams?

Just kicking an idea around...

Gee, nobody thought to ask US! :-).

The 11C90 was discontinued. Here are the possible sources we have
located, but they will all dry up sooner or later.

The 500-MHz frequency counter was dropped from the 1992 Handbook
because many of the parts had become difficult to locate. (We really
did try hard to select components that would be around for a while!)

 Why the Sheriff?  and why a [presumed] local court?  Aren't
 we talking Federal here?  Isn't it reasonable to expect a
 Federal Court to be a niche above?

 Sounds, to me, like we're beating a dead horse.  Seems that
 97.111(a)(2) and 97.403 focus squarely on the issue and
 provide the final, difinitive, answer.

 Now the disclaimer.  I'm not an attorney ... just a "reader"
 of the rules.

 Whatcha think ???

I'd like to expand on this last posting.  I recently took and passed all
of the US amateur radio exams (Novice thru Extra class).  To prepare for
these exams I purchased all of the ARRL License manuals.

The topic of SWR is mentioned several times in the above manuals,
particularly in the Technician and General Class Manuals.  In fact,
2 formulas are given for SWR : (see Now Your Talking p7-7)

 SWR = Emax/Emin

 SWR = Zo/R or R/Zo (whichever is >1)

These manuals also mention that a SWR of 3/1 will lead to a 1dB power
loss.  The Extra Class Manual also mentions the use of SWR circles on
the Smith Chart.

Now, I happen to have a Masters Degree in EE and I design ICs for
communications circuits on a daily basis.  So, I am familar with
reflection coefficients and how you calculate SWR with them (though
I must admit I forgot to take the sqrt of the power the first time
I looked at this posting).  I don't know how an average person who
studies for and passes even the higher level license exams would be
expected to know this.

I agree wholeheartedly with the feeling expressed by previous posters,
that Ham operators in general and those in this newsgroup in particular
should welcome any and all technical inquiries from fellow hobbiests
who are trying to advance their technical skills. I think that our
value judgements on the quality of the questions tends to discourage
legitimate curiousity instead of encouraging it.

Just my $.02 worth.

73,
Eric Smith

Actually, new all-digital technology will be used commercially for
the first time next year (code-divsion multiple access). It'll be
adopted because it's more reliable, better for data, and has higher
capacity than the present analog system. Higher capacity means more
revenue for the same capital outlay (from the service provider's point
of view), so there's a substantial incentive to get their customers to
upgrade. Customers also have an incentive to upgrade because of the
increased quality (far fewer drop-outs and much smoother cell handoffs),
additional service (better for digital data), and improved secrecy (the
digital format prevents casual listening with ordinary FM receivers, and
even someone equipped with appropriate decoding equipment will be unable
to listen to a conversation unless s/he hears the very beginning of the
connection to a given cell).

>I think that the mobile-phone companies should explicitly say
>that the phone calls are easily monitored by an FM reciever.
>I have heard many many things before on cellular freqs.

For what it's worth, my cellular "startup package" from PacTel came with
a supply of stickers saying "WARNING: This is a radio. Do not use for
confidential conversations."

Note that the 49mHz band -- where most of today's cordless phones live --
is not protected, and anyone can legally listen. I don't understand how
cordless phone users can imagine that their conversations are secret, given
that there's an ANTENNA on the silly phone, but a ham acquaintance of
mine recently helped the police wrap up a drug dealing operation this way.
It seems his girlfriend had an apartment two doors down from the drug dealer,
so he set up a scanner and voice-activated recorder on 49mHz. The result was
two hours of drug deals on tape, ready for the DA. No search warrant needed,
since the 49mHz frequencies aren't protected, except by the ordinary
"secrecy of communication" law.

The new 900mHz cordless phones work in the 902-928mHz band.

When people ask about this I usually tell them that if they use the radio
on police freqs directly that they should expect about at $10K fine (and
to
create considerable delaying confusion as the police try to figure out if
it
is a prank) but  if it's really a life at stake, I'm sure that that will
not be
 a consideration. If the fine is an issue, then they should consider all
other
methods first.  FWIW
