But **** nice. I used these on a comms manager project.
USB connectors suck. Period.

Subject: Re: [aprssig] DIN vs DB9
Here is my reasoning for opting to go with the DB9 instead of the Mini-Din:
1. The Deluo has a FEMALE connector standard on the end of it's cable.
This is of course there to accept a number of Deluo made adapters,
including serial and USB. In order to use Mini-Din, I would have had to
put another PCB mounted female on the board and then used a male to male
extention cable to make the connection. This would have increased the
cable length by at least three feet, not to mention the connector would
have roughly doubled the overall height of the adapter.
2. The DB9 "tracker" pinout has become very popular and is already widely
accepted as the APRS standard thanks to people like Byon and Scott adopting
it in the TinyTrak III and OpenTracker devices.
3. The DB9 tracker adapter is readily available for adapting the Deluo GPS
to a device, like my power/data adapter. Many Deluo owners already have
this adapter for items like the above mentioned trackers.
4. I wanted somthing that could be bought ready to go. Sure, you can chop
off the Mini-Din and put on your own DB9, just as Scott said, but I fear
too many people will wire it wrong and burn up their Deluo GPS.
I was asked to create a simple, plug and play solution to connect the Deluo
GPS receivers to Kenwood APRS radios, without having to modify anything.
Just use parts that can be bought ready to go.
Hope that clears things up.

Jason,
My suggestion. The plug into the D7 should be a right angle connector.
As it is in your picture, it sticks out too far.

Normally, I would have a right angle on the cable, such as my serial or
Garmin cables (http://www.rpc-electronics.com/kenwood.php), but I was told
by most requesters that this was intended mainly for the D700 mobile.
Since the D700 has a front mount panel jack, the straight plug seemed like
the best configuration to go with. The added benefit was, the same cable
CAN be used on both radios, it just sticks out a little further on the D7,
as you mentioned.
I guess if there was enough of a demand, I would produce both versions.
Straight and right angle versions.
Thanks for the input!

I found it --
"Back in the day" -- around 1997 --we had to use a different map for each
county we wanted to see weather information for. The total number for the
whole United States was 3284 files! They had names like AKKODIAK.map.
Here's the blurb I included with the zip file containing ALL the maps:

Actually, I think you are better off going with just the right angle.
There's no trade-off in using the right angle connector on the D700, and of
course there's a big plus in using it on the D7. Whereas the straight
connector is OK on the D700 and a mess on the D7.

Neither. VOice Alert is a recognition that all APRS mobiles have a
dedicated receiver on 144.39. This means that if you have no other way of
konwing what frequency someone is monitoring, that you can always call him
on 144.39 if he has the volume turned up.
The way to indicate to others that you are listening on 144.39 is to be
running CTCSS 100. This marks your packets with a PL of 100 so that others
can tell you are listening.
As a side light, if they have CTCSS 100 set, then they dont have to hear
anything on channel except such a packet from another Voice Alert station
who comes within about 3 to 5 miles. THink of it as a built-in proximity
radar.
But the WORST THING EVER is for someone to be transmitting PL 100 and NOT
BE LISTENING. This is very frustrating to mobiles who may not hear a
nearby voice-alert traveler for days or weeks, so it is exciting when he
actually passes within simplex range of someone else.
But if EVERY DAY, ALL DAY LONG, EVERYWHERE in his town, he hears a PL 100
station because it is a base station and NO ONE IS THERE LISTENING, then it
is very frustrating and kills the utility of the system.
The purpose of Voice Alert is to be aware of being in simplex range of
another APRS voice-alert station, and if you want to chat, to call each
other and QSY for the chat.
See the web page:

Hope that helps.

a short quoting from the web page:
||and set CTCSS-100 (136 in Europe)
Just for curiosity (and because the question has come up in the
TM-D700 Yahoo group): Why is another subtone than 100 Hz suggested for
Europe?
