APRSdom,
After 12 years, I am being forced to change servers for all of my 180 APRS
web pages. I assume that there are thousands of links on other APRS web
pages to mine...
My present server says they can re-direct for a while... But will GOOGLE
remember the old path or will it learn the new path via a re-direct?
In any case, however, I guess everyone will eventually have to modify all
their links if they point to any of my pages??
If anyone has any brilliant advice, please feel free to comment to me...
Bob

A very good tool for this.

I need a new APRS HT (and for that matter, I could use another mobile) - I
don't need anything fancy/expensive like the TH-D7 since I'm not going to be
looking at the display anyway, but I want something that supports the
standard mini-DIN connector. Any suggestions? The ham section of eBay is
so full of junk it's a major chore to find anything unless you're looking
for a specific model number.
Thanks...

Not aware of an HT that does.
FT-1500, TM-V7a, FT-847, all have the 6 pin DIN.

Shows how up-to-date I am on these things. I still use a Yaesu with thumb
wheels. =] Could've sworn there were a couple of HTs out there with a
mini-DIN.
Ok, on the mobiles, is this just something they're doing with the high-end
models? Has it really caught on yet?
I'm also working on a new tracker design - I'd been thinking of using a
mini-DIN connector on it for the radio side, but I'm considering switching
to an RJ-45. They're cheap, readily available, and I could set it up for
the pinouts used by the Kenwood mobiles. If board space allows, I could add
a second one on for a mic-encoder passthrough as well. I'm trying to fit
everything into a 3.9" x 3.15" board, though, and it's already getting
tight. The back panel's already got a USB type B, 2.1mm power, and DB-9
connector. The second serial port's just a pin header. I suppose the
RJ-45s could go on the front...

Full details on the MiniDIN 6-pin "DATA" connector follow. This is a
reprint of a post I have made many times on various groups and mailing
lists about this issue.....
====== PASTE ========
The 6-Pin MiniDIN "DATA" or "PACKET" connector is an industry standard
adopted by all the Japanese ham mfrs. It is now superseding the various
proprietary 7, 8 and 13-pin full-sized DIN connectors used by various
manufacturers. The contacts on this connector provide access to:
1) TWO kinds of receive audio:
Raw non-deemphasized discriminator output sometimes labeled "9600
Baud Receive".
De-emphasized squelched audio similar to what come out the speaker,
but at a fixed level unaffected by the volume control. It is sometimes
labled "1200 Baud Receive" or "RXD".
On multi-mode radios (Yaesu FT-817, Yaesu FT-100, Icom 706, etc),
only the "1200 baud" output will be live on AM, SSB or CW since the 9600
baud output is associated only with the discriminator of FM receivers.
2) TX audio input (sometimes misleadingly labeled "TX Data Input" or
"TXD") In some radios, a menu setting for "1200" vs "9600" baud will
determine if this input goes either into the same channel as the mic
input (but at a higher audio level) for 1200 baud packet, SSTV,
EchoLink, AFSK RTTY, etc, or is DC-coupled directly into the TX
modulator (for 9600 baud packet).
3) TX PTT (confusingly labeled "Standby" by Kenwood) -- normal
ground-to-transmit line just like most mic inputs.
4) Receiver Squelch status line (normally no sig-squelch-closed = 0V,
signal active-squelch open = 5V). Sometimes labled "COR" (Carrier
Operated Relay - an archaic term from the early days of FM repeaters),
"COS" (Carrier Operated Switch), "RX", "CD" (Carrier Detect), "Activity"
or "Busy".
5) Common/Ground.
Note that despite the misleading labels referring to data input and
output, the jack only carries AUDIO, AUDIO, AUDIO! THERE IS NO ACTUAL
RXD or TXD DATA in the sense of RS-232 or TTL-level streams of 1s and 0s
anywhere on this connector!!!
This connector is the perfect point to connect packet TNCs, soundcard
interfaces, phone patches, IRLP/EchoLink controllers, APRS trackers,
paging encoders, or any other device that needs access to the transmit
and receive audio of a radio.
These audio inputs and outputs are high-level (100-300mV), similar to
home stereo "LINE" input level seen at RCA jacks on tuners, amps, tape
decks, etc, rather the the 5-10mV level seen at most mic input jacks.
NOTE that this means that you have to set the audio output
("TRANSMIT") level of sound card interfaces, TNCs, data controllers,
APRS trackers, etc to a MUCH higher level than you would for a normal
connection into the mic jack. With some devices you will have to shift
internal jumpers, or exercise software menu commands to increase output
level (recent Kantronics TNCs for example).
On most radios with this port, grounding the DIN-6 PTT line mutes the
front panel mic input to prevent extraneous shack noises from getting
mixed with whatever you feed into the transmit audio input.
An annotated pinout diagram of this connector, useful as a worksheet for
making up cables, is on my website at:

Click through the link on this page which will take you to a directory
of assorted downloadable files, not a web page. Look for the file
MiniDIN6-Packet.pdf
Note that this connector is exactly the same one used on PS/2 keyboard
and mouse cables. A PS/2 keyboard extension cable is an excellent
source of a plug and cable assembly to mate with the jack on the radio.
[at a fraction of the cost of the optional Kenwood or Yaesu cable
assemblies! ] Cut the female end off, strip the bare end and connect the
bare leads to the appropriate pins of whatever mates with your tracker,
TNC, or soundcard interface.
