I just purchased the PK-900 with the 9600 baud modem option.
Can I use this with the FT-7400 or FT-2400 (Yaesu) ?
What modifications to the radio have to be made ?

Sign me up. I will also offer to schedule CW QSOs with anyone who wants
to practice. I have a Morse Machine keyer and it can be set exactly to any desired speed. I remember when I got my Novice license I was so nervous
my first few contacts my hand was shaking.
I am located in Cambridge, MA. Call is KE0SH.

Anyone that is using the alinco dr1200t data radio might
be interested in knowing that the Kenwood 8 pin mic i/e ts440
and ts850 model radios, possibly others will work as is on the
alinco radio. Nothing needs to be done, just plug and play.

Well, I don't know about others, but a lot of times my eyes tend to
'fuzz' over message .sigs, especially of those I've seen before. I often
find that I have to 'back up' to re-read a .sig because the neurons
responsible for flagging words that _might_ be an interesting .sig fired
_after_ I had already flipped on to the next message. And, to tell you
the truth, if you hadn't mentioned the change in your .sig, I might have
flipped past it without noticing.

To: info-hams@ucsd.edu
Posted-By: auto-faq 3.1.1.3
Archive-name: ham-faq-ptr
How to find the Rec.radio.amateur.misc Frequently Asked Questions list
------------------------------------------------------------------------------
This article will tell you how to find the answers to frequently-asked
Questions (FAQ) from rec.radio.amateur.misc. The FAQ articles are posted on
the 7th of each month. This article is posted on the 14th, 21st, and 28th of
every month as a reminder of where to find the FAQ.
The FAQ articles are intended to summarize some common questions on the
rec.radio.amateur.misc newsgroup and Info-Hams mail list as well as to help
beginners get started.
Besides the monthly posting, the FAQ is always available via anonymous FTP
and from e-mail servers. This article contains instructions for obtaining a
copy of the FAQ. It also contains the table of contents from the FAQ so
that you know which questions are covered by it.
Please provide a copy of the FAQ to any new or soon-to-be Hams you know.
Regular FAQ postings can help save network bandwidth and maintain a good
signal-to-noise ratio in the newsgroup. However, they can't do it alone - you,
the reader, have to use them. If you are a new user, please print and review
the FAQ articles and look at the instructions in the news.newusers newsgroup
before posting any articles. If you are an experienced user, please help by
refraining from answering frequently-asked questions on the newsgroup if they
are already answered by the FAQ articles. Instead, send e-mail to the user who
asked the question. (It will be helpful if you include the part of the FAQ
that answers their question, but not the whole thing.)
--How to obtain a current copy of the FAQ-------------------------------------
There are 3 ways to obtain a copy of the FAQ.
1) NetNews
2) Anonymous FTP
3) An Electronic Mail Server
Option #1: NetNews
------------------
If you are familiar enough with NetNews to look through previous articles on
your system, Option #1 above may be the easiest for you. The FAQ is posted
so that it should not expire from your site's news spool until the next one is
posted. Unfortunately, some news administrators do not honor the expiration
dates meant to preserve the FAQ.
Look in rec.radio.amateur.misc, rec.radio.info, rec.answers, or news.answers.
If the FAQ has expired at your site, try Option #2 (and ask your news
administrator to honor expiration dates for articles cross-posted to
news.answers if he/she can.)
Option #2: Anonymous FTP
------------------------
Anonymous FTP uses the File Transfer Protocol. It is only available to sites
which are directly connected to the Internet. If you don't know how to use
FTP and can't find a friend to help you, continue to Option #3. If your site
is not connected to the Internet, you should also continue to Option #3.
The following sites have copies of the FAQ:

Remember, when connecting to the remote system, use the login name of
"anonymous" and, as a courtesy to the site administrators, your e-mail address
for the password.
Option #3: Electronic Mail Server
---------------------------------
If you can't use Options 1 or 2, your only remaining option is electronic mail.
You can retreive a copy of the FAQ by sending a message to
mail-server@rtfm.mit.edu
The body of your mail will contain a command for the mail server software.
To get all of the FAQ (consisting of 70K of e-mail in 3 parts), place the
following in the first line of your message:
send usenet/news.answers/radio/ham-radio/faq/*

Subject: Kenwood TS850 and TNC distortion
To: info-hams@ucsd.edu
Several recent postings complained about voice and digital distortion
when using the Kenwood ACC 2 connector. I posted the connections that
I used with my TS 440. Nov '93 QST contains a note from KC6NSE in
Hints and Kinks that deals with this problem for the TS 850. He says
that he cured the problem with his KAM by changing the internal KAM
jumper K5 to HI (from LO). This sets the audio output. Alternatively,
Kenwood has recommended adjusting the TS 850 trimmer VR18 untill
SSB distortion disappears. (This fix is also for the PK 232).
Hope this helps, Shel WA2UBK dara@physics.att.com

I think that "beating up" on the ARRL has been the "in thing" to do for
people who think of themselves as brilliant. The phenomena reminds me a
lot of the 60s on campus when the truly "in" all vocally support the new left.
I have to say that a lot of them knew little about that movement, its purpose
or its aims. Nevertheless, the chique just had to lend their voices.
The anti-league group in an analogous manner looks at itself as elitist and
truly understanding ham needs (unlike the league in their opinion). This
diverse group of iconoclasts has established the importance of blind
opposition as important to the salvation of the USA (ala Wayne Green) and
hamdom. Newcomers who want to belong often parrot these anti-league
statements never having really taken advantage of all the services that the
league offers.
Its a shame really. We need the league to be stronger now than ever. Of course,
I am not advocating that that means no criticism. We owe the league
CONSTRUCTIVE criticism and suggestions. Those who feel that they have a
better way should take a greater part in the league not eschew it. Mindless
rebellion is not required for a successful democracy. Total rejection
based on the fact that the league does not agree with all of ones personal
views, is also not very productive. Invovlement is the key!

My beginning attempts at cw contacts were quite stressful. During each contact I would copy something like.. "/fb niqe to meet v, so LID qpq". What was wrong with my radio or was it ME ? Why does everyone I qso with call me a LID ? After some ti
me and practice I was able to copy what was actually being sent,
"/fb nice to meet u, solid cpy". Those OM's weren't rude at all, and they did send me a nice card. So now when I qso on cw I always use 599 and never soLID cpy.

Generally, few if any FCC offices now have the 610 form. Even if they did,
the FCC's policy has been to handle all forms distribution through a
contractor they use who is located in Maryland.
ARRL will supply the FCC 610 form. Simply write us at:
ARRL
Special Requests - FCC Form 610
225 Main St
Newington CT 06111
An SASE is appreciated. If you need more than one form, just ask!
Volunteer Examiners often have the 610 forms as well. VEs may
obtain their supply by writing or calling the ARRL/VEC.

Subject: The League SUPPORTS Morse... - rec.rad
To: info-hams@ucsd.edu
> Just goes to show you what the 'no-clue' license did in RI...
Being from RI, I must agree. The displined culture on the VHF bands is changing
for the worse... The problem is that the "clue-less" from CB land carry all their
poor operating habits to 2 meters. When more experienced hams try to diplomatically
point out that ham radio has a different set of practices, they get offended, rather
than using the constructive advice. There does not seem to be any means to reverse
this trend, short of increasing education and licensing standards. I cannot think
of one single policy that has done more to divide and degrade ham radio than the
"no-code" tech license and its published answers to brain-dead questions.
Is 2 meters a lost band?

Clark-
To the best of my recollection, the TU-8 data sheet had almost no
information. The information about installation and DIP-switch settings,
was in my TS-450/690 user manual, under installation of options. I assume
it would also be in the manuals of the other radios that use a TU-8.

If anyone has a copy of a maintenance manual for this old rock-bound handheld
I'd appreciate a copy or photocopy.

A 'trunked' system is a system of several repeaters linked by a
controller. They are normally located at the same site, but can be
spread around. Frequency assignments are dynamic.
When a station (mobile, portable, or base) wishes to make contact with
another, it briefly transmits on the trunked system's 'control' channel,
requesting a channel assignment. The controller assigns one of the
repeaters which is not in use, and commands both the requesting radio
and the desired party's radio (or a group, or the whole subsystem's
radios) to switch to that channel. When the conversation is concluded
(normally determined by a short timeout), the channel is released, and
the radios revert to listening to the control channel.
In this manner, many more groups of stations can share a chunk of
spectrum. Channel usage density can be much higher. And because
selective calling is inherent in the system, privacy and flexibility
is enhanced to some degree.
The actual techniques vary from manufacturer to manufacturer, but
they're quite similar in concept.
You may hear trunked systems referred to as SMRs - Special Mobile Relays,
as that what the FCC calles them. Around here, most of them on 800 MHz.

Add me to the CW contact list. At the moment I'm limited to 10/15/20/40,
but I hope to add 80 soon. My comfort level is about 10 wpm, but slower
is fine, of course. All I ask in return is a QSL card if your contact
is a new state/mode or state/band for me.
Send mail, and we can set up a schedule.

I just got this note from another source. Proceed at your own risk....
---------------
A call to Timewave revealed an "undocumented feature" which allows
the center filter frequencies to be shifted down to 400 & 500 Hz, a big
improvement.
(1) Remove the DSP-9's rear panel.
(2) Locate the three miniature sets of "prongs" (don't know what else to
call them) poking out the rear of the circuit board.
(3) The #1 prongs comes from the factory shorted. Leave them alone.
(4) Add a computer-style shorting strap to the #2 prongs.
(5) Your DSP-9 now has selectable 400 & 500 Hz CW center frequencies.
