The Sad Tale of a Musical Oscillator, Or how I'll spend my Xmas vacation
Well, what that silly first line was meant to allude to was the fact that
I have a chirping, whooping, and generally being anything but, stable
oscillator.
As CW is my preferred form of rf emission this chirping oscillator just
won't cut it.
Here are the specifics.
The rig is a TEN-TEC pm2 (early 70's qrp rig) It's a direct conversion
style transceiver. "The oscillator used for receiving operates directly at
the frequency being received. This allows the same oscillator to be used for
transmitting. When the XTAL/VFO switch is placed in the VFO position,
it connects the receiving oscillator output in place of the crystal."
This is a fairly crude design in my opinion.The DPDT switch has single
conductor hookup wire going from the switch to the board (six of them)
about 2.5 inches long. The switch selects between 80m and 40m lc circuits
which feed the base of the bipolar transistor, the oscillator.
The oscillator is followed by a buffer and then the XTAL/VFO switch.
After the XTAL/VFO switch is the driver stage and the final.
That's it on the radio
Soooo, what how about suggestions on improving the stability of the
oscillator. By the way there is no shielding around the transistor section
of the oscillator, the inductor is in a metal can but that's it.
Any suggestions would be appreciated. I am going camping down into Mexico
and want to use my new (to me) VFO capable radio as opposed to my MXM
rock bound QRP rig.
Thanks in advance.

Does anyone know of any Hamfests in Michigan within the next few months?
I'm particularly looking for used base transceivers, apartment antennae,
and hand-held transceivers(Of course I'm a ham virgin, how nice of you
to notice)
Any info at all on a hamfest or -working and in good-to-excellent condition-
equipment will be very appreciated(email even moreso)

Subject: Hands-free portable 2-way radios?
To: ham-equip@ucsd.edu
My friends and I are looking for some radios to talk to each other
while we ski. Radio Shack used to carry one where the earplug served
as the microphone also. There was no big boom mike in front of you.
Unfortunately, this radio has been discontinued.
Does anyone know of a similar product? We'd like to get one that
doesn't require a microphone in front of your mouth. Hands-free
operation is a must, and range is not that important.
Please respond by e-mail or post to alt.toys.hi-tech. I will post a
summary of responses.
Thanks in advance,
Phil

Hello all! I am wondering if there is anyway I can add SSB to my
Heathkit DX-60B (currently CW/AM) so I can do 10M SSB. I would prefer
a "black box" between the transmitter and the antenna, although a
hardware modification would be considered. If you have any ideas,
please e-mail me at ncc2001@cwis.unomaha.edu or packet at

Mike:
I have three Alinco DJ-180Ts (two other amateurs in the family) and we
really like them. I would think that the same type of engineering went into
the 580T. The seem to be rugged and work well.
My first radio (last April) was a Yaesu mobile which I use when commuting.
I would go the same way again for the power output (when needed - usually
stay on low power of 5 watts). A lot guys in the commute use HT's, but
they get more intermod than I do (like zero on my FT-2400H). Another
friend of mine has the Yaesu dual band HT and really likes that one. The
only feature I don't have that I would really like is autodial. When
driving, it would be much safer to hit 1 or 2 buttons than all the ones
needed to dial a phone number. It's OK for dialing as it is when I am
stopped.
Have fun,
Milt
PS: you can also find decent used equipment here in rec.radio.swap. My
problem is in knowing anything about the slightly older rigs that are not
in the catalogs any more.

Subject: IC229H Power connector
To: ham-equip@ucsd.edu
My Icom IC229H 2m mobile rig has a power connector on the back (amazing)
that connects to some heavy gage wire. My question is this: Is that a
common connector, something I could pick-up at the Shack? I would like
to move it into the house but leave the power cable in place in my van
in case I want to re-install it in the van. I'm sure I could buy a replacement
from Icom or a dealer, but would rather make my own.
Thanks for any advice.

Subject: Kantronics Packet Communicator Help
To: ham-equip@ucsd.edu
I was just recently loaned a Kantronics Packet Communicator by a friend.
I've wired it all up and tried to talk to it via RS232 to no avail. Trying
a null-modem adapter did give me something, screenfulls of garbage, but
repeating garbage.
Is there anyone out there that can tell me what rate the TNC talks to the
computer at, and how many bits, parity and stop? I've alread figured out
the TTL/RS232, and Test/Normal jumpers but I'm not sure what the HI/LO
jumper is for. I suspect it's DTR but can someone confirm this? In
addition, what character must one send to the TNC to get it to configure
itself properly? I know on the PK-232 it's an asterisk, and Ctrl-C gets you
out of a mode. How about on this one? Please direct all answers to email as
I don't scan this group that often.
Thanks,
Tony

I believe that there have been several posts on this issue about the 202
but I didn't save it at the time.
My problem is that I am getting reports of low audio on my Radio Shack HTX202.
I don't have similar problems with my ICOM 32AT and ICOM 2AT so the problem must
lie in the HTX202. Could someone send me the the instructions to adjust the
mike gain?

You might treat "low mike gain" as a feature! Talk louder and you will
get normal signal reports. The "feature" is that the radio will work
better in noisy surroundings, as the mike won't pick up the noise as
easily. (Then again, your surroundings will be noiser when you have to
talk louder....)

I have a Magellan NAV-5000 GPS handheld navigation receiver for sale.
The unit is in excellent condition. It was used for only one day
to determine the location and altitude of a group of radio trans-
mitting sites.
It has 5 simultaneous receiving channels to allow continuous
tracking of the unit's current latitude, longitude and altitude,
while the 5th channels searchs for additional available GPS
satellites in order to maintain the continuous tracking process.
The unit has the NMEA port for connection to auto-pilots,
computers , etc.
Will sell with original packaging and documentation and UPS
2 day AIR shipping for the first $600 money order or cashiers
check . Please call or email to see if the unit is sold before
sending any money.

Subject: Mods for tm732 & which dual-bander to buy?
To: ham-equip@ucsd.edu
I just purchased a Yaesu 5200 & it doesn't do what I want to do -
specifically allow me to control it remotely via an HT w/DTMF pad.
This is quite important to me. It does provide repeater operation,
which is one of my essential points. HRO will give me full credit if
I bring it back.
The Kenwood tm732 apparently does allow this (along with a remote head
which is also essential), and sounds like a good rig.
Any suggestions on which rig to get? Anyone have mods for the 732?
Thanks,
Craig.

Subject: Program to control Icom R-7100???
To: ham-equip@ucsd.edu
A friend recently purchased an Icom R-7100. It is a very nice unit and they
have purchased the Icom CT-17 option which allows communication between the
computers serial port (in this case com-2) and the radios CI-V interface.
The problem is that the Icom documentation included with the radio and the
CT-17 does not offer the best information as to how to use this interface to
it's fullest capabilitys. They offer several programs which are written in
Basic that will preform basic functions, but the programs appear to be
poorly commented and will require modification to run on their particular
version of Basic.
I have located several programs which appear to be able to drive this radio
namely Autolog4 and Icom.c. But, these programs are specifically designed
with transcievers in mind. Does anyone have any knowledge of a good program
that will exercise all the capabilities of this radio? If so please eMail me
some info. You can even UUencode the program and eMail it to me if you have
one. My friend is an Extra Class ham, but not a computer guru. So something
to the point would be far more enjoyable for them. Certainly someone has
gone to the trouble to write a Windows application for this purpose???
Please eMail any comments if possible so I'll be sure not to miss them.
Thanks in advance,

To: ham-equip@ucsd.edu
I have pried apart several of the FNB-17s, and you can get them apart if
you are paitent. They come apart just like the AA packs (FTS-17?) but
you have to crack the glue holding them together. I have had good luck
at smacking the glue line against the sharp edge of a table to crack the
glue and prying them open starting at the top. They will resist because
in addition to gluing the edges, there is some goop inside that is like
RTV that glues the batteries to each half that is very resilient. just
keep prying and you will get them apart. Start with your most beat up
pack as the pack will take some abuse until you ghet the hang of it.
If you want a real challenge, try disassembling a motorola pack :-)
good luck

Or the Icom BP-8?'s....Much like the Yaseu except that the bottom of
the pack is the only access. The cells are glued to each other and ALL
6 sides. And the to make things worse, the contacts in the top hold
the batteries in as well.
I got a cell out, and drove the screwdriver into my hand. OUCH! So
maybe I am an moron. I got my T1000SE pack open w/ no problems tho...
hmm..
If you know how to get a Icom BP-8* back open let me know. :)

I see plenty of advertisements for replacement battery units that fit inside
the OEM cases. I have some dead Yaesu FNB-10 packs that I'd like to repair.
The problem is they are glued together and apparently difficult to
disassemble. The one manufacturer I called won't give any data on how to
disassemble the packs (wonderful service).
Has anyone successfully disassembled this particular pack, or similar ones
and found a useful technique to apply to glued-together packs? Obviously
I can attack this thing with a utility knife, but I was hoping for a bit
more finesse - I have several to fix.
