Am in the process of configuring another tracker for our Mason County, WA
Dept of Emergency Management.
I will be using an old KPC-3 (plain KPC-3 not the +) and want to feed it
external power via the DB9 connector. I made the cable like I do for the
KPC-3+ and went inside the TNC to move the jumpers, however, the layout is
completely different from the +. In the + I have to move jumpers J6 and J7
from center to pin 2. On the KPC-3 there is no such configuration. There
is a J6 but it is only 2 pins which presently are not connected. I found a
spot for a J7 but there are just 3 holes in the circuit board. I do not
have the manual nor the schematic for the KPC-3.
Does someone know what the internal configuration needs to be to supply
external 12 V power to the TNC via the DB9 connector. If so, please send me
the particulars.
Thanks,

Just experimenting with a few ideas for storing location info into a memory
stick and short APRS pos TX
1. example 2734.45S15306.22E
2. Strip off dec point - you know the last two in are where the dec point goes
3. 273445S1530622E
4. each number is going to be 0-9 that requires 4 bits
5. you can stuff two digits into one 8 bit number and split at rx end
6. 2 = 0010 7=0111 3=0011 4=0100 4=0100 5=0101 1=0001 5=0101 3=0011 0=0000
6=0110 2=0010 2=0010
7. That makes 13 x nibbles, you need 14xnibble to make up 7 bytes.
8. Use the last nibble to store S/N E/W eg 0100 = NW 0000=SE 1100=NW 1000=NE
At the receiver
00100111 00110100 01000101 00010101 00110000 01100010 0010 0000
2 7 3 4 4 5 1 5 3 0 6
2 2 SE
Go in 4, add a dec point, go in 2. add the N/S bit, go in 3, add dec, go in
2, add E/W
2734.45S15306.20E
Ideas ?
This seems to fit.

Herb, the older KPC3 will do power via pin 7 of the db9. I have this setup
running on 2 mobiles I rigged up for locals. Forgive the spelling, this is
from the manual, page 98 July 1 1992:
Pin 7 of the db9 connector may be configured to allow you to apply power to
the KPC3 or perform a hard reset on your KPC3 without opening the case.
To power the KPC3 from pin 7 of the db9 connector, you must install two wire
jumpers on teh pc board. Install one jumper at the pads marked J8, between
the center pad and the closest pad to the back of the KPC2 (marked as 2).
The second jumper is installed on the pads at J9 between the center pad and
the pad closest to the back of the unit. (marked as 2).
To perform a d hard reset of the KPC3 from pin 7 of the db9 connector, you
must install two wire jumpers on teh pc board. Install one jumper at the
pads marked J8, between the center pad and the closest pad to the front of
the KPC2 (marked as 1). The second jumper is installed on the pads at J9
between the center pad and the pad closest to the back of the unit. (marked
as 2). Applying ground to pin 7 when you power up the KPC3 will then
perform a hard reset.
If you need any help, you can email me directly.

Don't have the WWIII but have a WeatherMonitorII. I think (hazy memory
warning) that the approach is similar between the two boxes.

Unfortunately, it's more than just a cable. There's a small piece that
installs in the back of the unit. This provides memory and I think the
serial port driver. The rest is just a cable.
The additional piece is essentially a data logger. With my unit I can set
it to any one of a number of logging intervals. I use the 15 minute
interval, which gives me enough memory to log about 15 days worth of data.
When being home permits I download data from it once a week. I can easily
miss a week and still be OK.
The logging happens continuously during that interval. Things like highs
are recorded at any time during the interval. (i.e. if you get a big wind
gust at minute 7 of a 15 minute interval that's the value that is recorded)
Things like current conditions are averaged over the interval. Even the
highs have a small associated interval with them to eliminate data
glitches. (I believe I read that the high wind speed is averaged over an 8
second interval.)
It's spendy but it's more than a cable. I don't know if it would support a
directly connected cable without the data logger or not. My PC isn't
connected to it all the time so that wasn't a consideration.

Just a brief note to say that the Spirit of Piccard solar Montgolfier (i.e.,
hot air balloon) will most likely be launched this morning from Warren,
Michigan. This experimental balloon will carry an APRS tracker and will
also be digipeating as KC8UCH-11.
The expected track (somewhat unpredictable due to the experimental nature of
the envelope - float altitude is estimated at 40k feet) will take it south
and then south-east, possibly as far as the Carolinas. It is likely to
float all day and into the evening hours with final descent expected around
sunset.
Your tracking reports, APRS logs, etc., are greatly appreciated! Also, any
help in physically retrieving the payload once it is down would be most
welcome! There is a $xx reward for the return of the payload and envelope
(it should come down fully attached - and there is a temperature logger
*inside* of the envelope).

I am trying to determine the cause (and fix) of a problem which is showing
up as distorted packets being posted to findu.com. Take a look at the
following link and notice all the distorted variations of the calls listed
in the display.
http://www.findu.com/cgi-bin/near.cgi?call=W2GFF-7
[Note: I used W2GFF as an example of a victim of the problem and not because
I believe his station has anything to do with the problem itself.]
If you look at all of the invalid entries, you will notice that they all
passed through K5ZRO as a digi and in most cases were sent to the internet
via AA5ED-10. I have been able to find a few invalid packets over the last
several days that in fact went through K5ZRO but went to the internet via a
different IGate so I think I can eliminate AA5ED-10 (running UI-View 32) as
the problem. This most likely seems to leave the K5ZRO digi as the only
obvious common station.
How can this happen? Could a digi be passing packets that don't have a
valid check-sum? Are they being received properly but being distorted
inside by the digi?
I have sent an email to the club that sponsors the digi to try and get a
contact person for the K5ZRO digi but to date have no information.
Has anybody seen anything like this before? If so, give me any insight you
have so I can pass it on to the K5ZRO trustee.
Thanks!
