120 wpm is 2 WORDS per second, or about 10 characters per second.

In my previous posting, I analyzed the required bandwidth based on
a ringing fall-off rate of three time constants during the "off"
time between dits and dahs.  Ignacy's method of looking at the
frequency content of the baseband signal (i.e. the keying rate)
is also valid.

The highest pulse repetition frequency is when you are sending a
string of dits (for example, the letter H or the number 5.)
My previous example of 48 wpm results in 20 dots per second.
A Morse code signal can be considered to be an AM (ampltidude
modulated) signal that is 100% modulated with a square wave, in
this case a 20 Hz square wave.  Since an AM signal has two sidebands,
the bandwidth must be at least 40 Hz.

My previous result was 38 Hz, in good agreement with the above result.
The required bandwidth is proportional to keying speed so, for example,
24 wpm would require about 20 Hz, etc.

It's actually twice that, since the modulated 750 Hz tone has two sidebands.

I have pretty much narrowed down my choice to these two 2m ht's.

I'd like to get comments and opinions from people in the net who
have actually used both.

currently, I am leaning towards the dj-162 because of its wide
receive.

please email responses if possible.
thanks in advance.

Not if I can help it. I will use any influence I have left as the Former
Public Service Director of the Northern Alberta Radio Club, and any avenues
of information transfer, such as the Packet Radio system, to ensure that people
of your kind are carefully scrutinized. This will not prevent you receiving
your ticket, but it may make you very uncomfortable when your past catches up
with you.

I was shocked from this message !! I always thought that Amateur Radio
was created and is still popular due to it's promotion of friendship !!
So what if the man was a "pirate", what matters *now* is the fact that
he is going straight !!! If he seems to be sincere about his "turn around"
he should be given the chance to do so !!!
Every possible effort must be made to reform the radio pirates with the
real *amateur" way, not with threats and vengence like you have done !!

To: [e-mail]

I do much backpacking, and increasingly I go alone.  I'm thinking
about the possibility of bringing a communications radio with
me.  Do these things have a large enough range to work out in
the wilderness?  I typically find myself only in California.

What's the cost involved, and how big are the radios?

I listened to some of the comms in Socal. What I heard reminded me very
much of what was going on here (NorCal) after our 7.1 in '89. CelTel
has had a LOT of publicity as has Internet. At the same time, I've seen
NO media mention of Amateur Radio activity down there. Sheesh!

While CelTel seems to indicate that any boob can provide comms in a disaster,
keep in mind that CelTel relies on landline and that the CelTel "HT" is
just as subject to dead battery syndrome and a 2m HT. The difference is that
the ham has (hopefully) had some training on *HOW* to handle disaster comms
and some idea of where hir next battery charge is coming from.

The experience with cell tel in '89 was that it didn't work very well when
the batteries were charge and not at all when they weren't.

Subject: nearby broadcast antennas
To: [e-mail]

Hello All,

I have a question about a possible interference problem  that I may soon be
experiencing.

I am considering a move from my current QTH to a new apartment.  However, the
apartment I'm considering is located immediately next to three transmitting
towers.  All three are commercial broadcast stations, one FM (102.7 MHz), one
TV (Channel 10) and one AM (1240 kHz).  I am currently active on 2 m, 440 MHz,
and am very active on HF for shortwave listening and will soon be working
the HF ham bands.  I am worried that  moving so close to the towers will
cause problems with the performance of my equipment (noise, desensing, images,
intermod, etc.)
I plan to set up some dipoles very close to the tower sites and am worried that
it could ruin my enjoyment of the radio hobby if all the RF causes problems.
Has anybody had any experience with this???  Is it anything to worry about???
Any experiences anyone has had (or even just bold speculations from more
seasoned operators/listeners) would be greatly appreciated.

Thanks in advance,

Ron Synowicki, KG0HX

Well that's what the power company is going to do. Many problems like
this are due to something coming loose mechanically on the pole. Jarring
it is the way they pin it down. This *is* best left to professionals,
however, since a possibility exists that striking the pole could make
a permanent short, or drop something on you.

Subject: Power Line Interference
To: [e-mail]

For the past 3 years I have been trying to track down some noise that appears
to be coming from the power lines. I have walked around with a portable radio,
driven around (for miles in all directions) in my car seeking the source. The
source seems to come from one of the two power poles across the street from me.

    This noise tends to show up in the Winter time or on cool or rainy
Summer days. In the Summer time I might have the noise on a day that remains
cloudy (therefore cooler). In the Winter time the noise also tends to also
show up mostly (but not always) at night time when it is cooler. We are talking
about Florida, so in the Winter time it doesnt normally get that cold. Now here
is the weird part: The noise has a cyclic period of about 1.5 seconds on and
1.5 seconds off. This part doesn't vary. If I have the noise, it has this
period. Now there are no capacitors on the power poles around me. The pole that
I suspect has a transformer on it. Can a transformer do this? How? Is there
some sort of capacitor or protection circuit on these xfmrs that can do this?

    Normally, I cannot determine the source (this changes). My 20 meter
beam seems to tell me which pole the noise comes from, but if I walk up to
the pole, with a portable radio I normally am not able to zero in on it.
I have called the power company in the past to repair a problem which I was
able to point them to. I am reluctant to call them on this one, even though
it tears up all from 1500 khz to 21 mhz. I have heard that this sort of
interference can originate miles away and be picked up by the power lines at
some distant point (my house).  I imagine I'll call the power company for
resolution, but would like any input I can get before I do it. Please don't
tell me to go beat on the pole!

Read the FT-415 mods. Exactly the same internally. Get 'em of FTP from
