Subject: Alinco DJ180T mods?
To: [e-mail]

I hope this isn't a FAQ that I have just missed, but here goes
anyway...

Although I see many mods listed in various FTP sites for Alinco
160's and 162's, I never see any for the DJ180T. Are the mods the
same for the 180 as for the 160? Where can I find mods for the
180? I have heard that one of the mods will make wideband recieve
go even wider than the 130-174 range. Help!

Loops are strongest in the plane of the loop, and have a null
perpendicular to the loop.  Horizontal mounting makes it
omnidirectional, and vertical gives you a null in two directions that's
good for cutting down local noise sources.

Since the loops primarily operate on the magnetic portion of the radio
wave, it sometimes helps to try both orientations and see which is
best for a particular location.  This is especially true if the
antenna is within 10-20 feet of a large mass of metal (metal roof,
fence, etc).

Periodic Announcement - ARRL Email Information Server ([e-mail])

The services that the ARRL provides via the internet include the
Email Information Server and the Technical Information Service.
The Information Server is an automated mail server that gives you
access to many of information files relating to various facets of
Amateur Radio.  You can retrieve any or all of these files by
sending an email message to [e-mail] here at ARRL HQ.
Each file you request is then mailed to you automatically.

To use it, mail messages to:

   [e-mail]

Each line of the message body should contain a command as shown below.
The subject of your message is not processed and may be omitted.  You
may place as many commands in a message as you want.  The files you
request will be sent to you in separate messages.  Only ASCII text
files are supported.

Valid INFO commands:

reply <address>  (may be needed - see below for explanation)
help
index
send FILENAME   (example: send prospect.txt)
quit

In the above message example, "help" retrieves a brief set of
instructions for info, "index" retrieves a list of available files
and "send prospect.txt" retrieves a text file containing information
on becoming a radio amateur.

Note to users with FTP capability:  All of these files are also
available by anonymous ftp to oak.oakland.edu in the
pub/hamradio/arrl/infoserver area.  Retrieve the file index.txt
in the /league sub-directory for a complete listing of available
files.

If you want to retrieve several text files with one message, use a
separate line for each "send filename" request.

Your From: field or Reply-to: field in your header should contain a
valid Internet address, including full domain name.  If your From:
field does not contain a valid Internet address, the answer will not
reach you.  If this is the case, then use the reply command as shown
above.  When needed, this command should always be the first command
in your message.

IMPORTANT: Please use the quit command in your message.  This will
           prevent processing errors from message signatures.

PLEASE NOTE!:  This is an automated system not capable of handling
written requests.  Any questions on the info-server or the content
of any of its files should be directed to [e-mail].

ALSO NOTE!: Do *NOT* reply to messages sent from [e-mail] - the
reply address is redirected to keep bounced messages from endlessly
looping.  Write a new message to [e-mail] instead.

The Technical Information Service gives League members on the
internet better access to the knowledgeable technical staff here
at ARRL HQ.  Questions relating to Amateur Radio and related
technical topics are welcome.  To use this service, send a normal
e-mail message to [e-mail] with your question spelled out in
plain english.  For best service, be as specific as possible and
keep your line length in messages to a maximum of 80 characters.
Due to personnel limitations, priority will be given to questions
from League members.

Not to mention that even a dummy load can radiate enough power for a
QSO.  ANY antenna will radiate power, no matter how small, so long as
its properly matched to the rig. Anyone who doubts it should read
Maxwell's excellent book "Reflections," or any of Kurt Sturba's
columns in World Radio.

Even a small loop antenna is "the real thing."  It may not have the
efficiency of a full-size antenna, but it WILL radiate a signal.  For
that matter, so will a dummy load.  Any antenna that can be properly
matched will radiate a signal.

I suggest you pick up a copy of Maxwell's "Reflections" and check it
out.

This is your opinion.  I respect it.  I also disagree with it.  If a repeater
serves 200 users, what difference does it make if those 200 users pay dues to
a closed system or just showed up on an open one?

The point here is: Is the frequency being used?  If so, what difference does it
make of the system is closed?  If the frequency isn't being used, then the fact
that the radio is closed or open again makes no difference.

There are open systems in Houston which get little or no use.  Certainly much
less use than my closed system.  Am I to be declared "less worthy" even though
my radio is used more?  That dog won't hunt.

Perhaps. However a significant number of amateurs believe that the 'closed'
repeater is contrary to the principle that no individual or group 'owns'
a frequency.

Those of us who feel this way 'tolerate' closed repeaters in the spectrum
where there is plenty of available space, on the premise that no harm is
done.

However, in areas where spectrum is becoming critical, we believe that the
band plan should dictate that OPEN repeaters have priority, sometimes to the
extent that even existing closed sites are offered the option of either
opening up or giving up the allocation. And we also believe that the
'band plan,' as developed by local and national organized Amateur Radio
groups has sufficient authority to dictate fair spectrum usage.

We believe that groups that put up closed repeaters must make this trade
off... ...that that is the price of exclusivity. Presumably, however, the
greater occupancy should offer them a better market for sale of the old
'machine,' should they have to move to 1.2Ghz.

The 'closed' repeater has been the counter-example to the 'no-one owns
a frequency' principle which has guided amateur radio for its entire
existence. I see no reason to turn away from the older principle in order
to keep the price of exclusivity low.
