GPS Plot is a packet radio decoder that is designed to convert APRS position data into GPWPL sentences.
These are sent to the GPS serially and will plot APRS stations on the GPS map screen as way points.
Like my other PIC APRS projects, it's aimed toward the do it yourself builder and is open source.
It will decode and plot both conventional and mic-e compressed position reports.
There are two hardware versions:
* One uses a MX614 modem IC. [http://www.ringolake.com/pic_proj/decoder/rx_206.html http://www.ringolake.com/pic_proj/decoder/rx_206.html]
* The other uses a zero crossing detector design. [http://www.ringolake.com/pic_proj/zcd/zcdmodem.html http://www.ringolake.com/pic_proj/zcd/zcdmodem.html]

SoundCardInterfaces

2008-11-24T18:13:58Z

Glenn: +Category:Hardware

There is a lot of information out on the web about soundcard/radio interface hardware.
If you decide to use any kind of software that employs your computer's soundcard as a TNC,
you will need to buy or build such an interface. (If you use a serial or USB connected
external TNC then you don't need a soundcard interface.)

This device is '''not''' mode or band specific. You can use the same
device that you employ for other digital modes (PSK, slowscan, RTTY, etc.), as long
as it will connect to the radio and the computer combination that you are going to use for APRS.
For example: if you use your Icom 706 mkIIG (an all-mode HF through 70cm rig) for PSK-31
on HF, you probably can use the same soundcard/radio interface device for APRS. Just
set up the radio for the mode, band and frequency used in your area for APRS operation, and
run your APRS software instead of your PSK software.

----
The task is to connect the audio inputs and outputs between the radio and
soundcard. Solutions range from direct connection to electrically isolated
systems using audio transformers or optical coupling. Some provision for
keying the radio is also useful. Usually this involves a connection to the
computer via serial port (USB or rs232) or parallel port.

This is a good opportunity for doing a little junkbox homebrewing.
The guts of old computer modems usually contain audio isolation transformers,
rs-232 ports and other hardware bits.

For an off-the-shelf solution,
[http://www.westmountainradio.com/ West Mountain Radio's] RigBlaster units
are popular.

----
As to software for doing APRS over a soundcard, investigate [[LinuxSoundmodem]] for Linux or Solaris, and [[AGWPE]] for Windows. Either of these will do the tone encoding/decoding, then you need a compatible APRS program to connect to them.

SiteAlert

2008-11-24T18:13:16Z

Glenn: +Category:Hardware

Site Alert is a device that connects to the serial port of a UI-DIGI[A] APRS[B] Digipeater. It is used to provide local site information from a remote Digipeater site via APRS Telemetry data.

The data is transmitted every 30 minutes and includes the average of four supply voltage readings, the current in-building temperature, number of PTT’s and the current mode of the Site Alert. The Parameter, Unit and Equation messages are sent once a day.

Should the average voltage fall below a pre-programmed value Site Alert will turn off the Low Battery output until the average voltage reaches the upper pre-programmed value. This output can be used to control an external relay to remove power from the TNC and Radio.

SiteAlert provides protection from 'locked Digipeaters'. If the Digipeater does not transmit within a set timeframe it can be automatically reset.

The battery alarm or the external alarm inputs will cause an APRS Item and an APRS Message to be transmitted.
Alarm Messages can be extended to an Email or SMS notification gateway.

Site Alert uses an Atmel AT90S2313 micro-controller, ADC0831 Analog to Digital converter, Dallas Semiconductor’s DS1820 Temperature sensor and DS1307 Real Time Clock.

Further information on SiteAlert can be found at [http://www.aprs.net.au/Site%20Alert%203%20Web_2.htm SiteAlert Web page.]

AntiTracker

2008-11-24T18:12:30Z

Glenn: +Category:Hardware

=====The Anti-Tracker=====
The AntiTracker is a new concept in GPS tracking systems. The idea behind the AntiTracker is that many units in the field do not need to have their positions reported back. These field units are however interested in where the units being tracked are located.

Think of marathon race. The first and last runners in the race are being tracked thanks to trackers on vehicles following the race. Each of the checkpoints is stationary, but they want to know when the first runner will be reaching them, and how long it will be until the final runner passes them.

This allows significant cost savings in terms of not only equipment capital costs, but also in terms of operational costs including licenses and batteries.
With this in mind, Radioactive Networks has just produced what we are calling the 'Anti-Tracker'. Rather than develop the display interface, we have decided to use a commercially available interface - a simple GPS reciever.

http://www.radio-active.net.au/web/tracking/at2.jpg

====Two Models====
Initially, Radioactive Networks will be releasing two versions of the AntiTracker. They will be :-

**Basic** - The ability to display positions on a GPS receiver with NMEA input - meaning that it will not work with the entry level Garmin eTrex. The design also uses two embedded processors, rather than a single integrated processor.
**Pro** - The Pro version of the AntiTracker contains all the capabilities of the Basic unit, except it will upload to GARMIN GPS receivers in BINARY format, meaning that it will work with the basic Garmin eTrex. An upgrade will include the capability for ICONs to be also uploaded to the GARMIN.

====The AntiTracker BASIC====...
is designed so that the HAM RADIO community can recieve the benefits of the AntiTracker without having to go for the expense of the PRO model. This device will not upload positions in GARMIN Binary mode, nor will it upload any symbols assigned to objects. In fact, Symbols may even change every time a new position update is received.
One of the areas that most tracking systems concentrate on is acquiring GPS positions and getting them back into a central location. Some even send the positions back to the GPS tracking units. http://www.radio-active.net.au/web/tracking/atbasicv1.jpg
What has not been done is create a distributed system in the field, reporting the positions without being tracked themselves. This allows significant cost savings in terms of not only equipment capital costs, but also in terms of operational costs including licenses and batteries.
With this in mind, Radioactive Networks has just produced what we are calling the 'Anti-Tracker'. Rather than develop the display interface, we have decided to use a commercially available interface - a simple GPS reciever.

**Compatible GPS Receivers **
Compatible GPS receivers include The...
- Garmin GPS12
- MAP168
- GPSII+
- GPSIII
- GPSIII+
- EMap(updated Software)
- Etrex Venture, Legend, and Vista(with updated software)
- Garmin 45
- StreetPilot III(with 2.11 and above software)
- GPS 12XL

Basically any GPS that understands the GPWPL NMEA sentance will work. This includes many Magellan GPS receivers too.
The GARMIN Etrex BASE MODEL WILL NOT WORK. Neither will Garmin GPS-V or the Garmin Street Pilot (First Version).
The position of all the users being tracked appears on the GPS receiever along with any roads and other features programmed into the device. Then when the person being tracked moves, the icon on the GPS will move too.

**Implemented Packets**
For the technically minded, we will now include information on the packets that this device will decode -
- Standard Position Reports
- Standard Position Reports with Timestamps
- MIC-E Position Reports
- MIC-E Position Reports with Timestamps
- Standard Object Reports
- Standard Item Reports

**Building the AntiTracker BASIC**
Our prototype is only about 2" x 3" making it quite portable. No circiuit board is available at this stage. This design uses four inexpensive IC's. The components we are using include a couple of PIC16F628's, MX614 and MAX232. None of these parts are expensive, and are available surface mount.

The circuit diagram of the AntiTracker BASIC can be found here.
http://www.radio-active.net.au/web/tracking/antibasicv1.tif

You will need to contact us for programned IC's or the HEX file to program your own. Please note that there are two pages to this circuit diagram. GIMP for instance will not read the second page. Kodak Imaging supplied with many versions of the Windows Operating System will work correctly

====The AntiTracker PRO====...(still in development)

One of the areas that most tracking systems concentrate on is acquiring GPS positions and getting them back into a central location. Some even send the positions back to the GPS tracking units.
What has not been done is create a distributed system in the field reporting the positions without being tracked themselves. This allows significant cost savings in terms of not only equipment capital costs, but also in terms of operational costs including licenses and batteries.
With this in mind, Radioactive Networks have just produced what we are calling the 'Anti-Tracker'. Rather than develop the display interface, we have decided to use a commercially available interface - a simple GPS receiver.. http://www.radio-active.net.au/web/tracking/anti-pro1.jpg

The PRO version of this device can use eithe the $WPGPL sentences understood by many GPS receievers that allow NMEA uploading, or GARMIN BINARY format understood by the newer Garmin eTREX GPS receivers. This version is based on the PIC16F876 processor with an MX614 modem IC. The code is getting close to totally filling the memory of the processor. During testing we also discovered that the CPU clock needed to be doubled in order to process the data in the available time.
The position of all the users being tracked appears on the GPS receiever allong with any roads and other features programmed into the device. Then when the person being tracked moves, the icon on the GPS will move too.

**Progress**
This project is getting close to completion - at least on the firmware side. We are now decoding normal and third party packets and displaying them on the GPS receiver in GARMIN and TEXT modes. At present packets are not being correctly decoded when one packet follows within 100 mSec of the previous packet being completed. Although rare in object tracking, it is quite common in iGate operations.

Since GARMIN and NMEA operate at different speeds, we are also going to make the selection of the mode switchable. This needs to be implemented. The GARMIN protocol has the ability to set ICONs and we also hope to implement this.

A circuit diagram for the Anti-Tracker PRO is available here.

http://www.radio-active.net.au/web/tracking/atpro.tif

**Implemented Packets**
For the technically minded, we will now include information on the packets that this device will decode -
- Standard Position Reports
- Standard Position Reports with Timestamps
- MIC-E Position Reports
- MIC-E Position Reports with Timestamps
- Standard Object Reports
- Standard Item Reports

**To Do**
- Remove the MAX-232 IC
- Surface mount the entire board
- Look at power consumption
- Packet OK LED.
- Fully test
- ICON
- TX and RX at the same time
- Mode Pin

WhereAVR

2008-11-24T18:10:52Z

Glenn: linkupdate, +cat

The WhereAVR is a small, lightweight, low-power, and low-cost APRS tracker much like the commercially available TinyTrak and the open-source OpenTracker. What sets it apart is a full complement of analog and digital I/O, as well as the ability to decode ax.25 packets. This allows for the reception of remote commands without the need for a "real" TNC. It is designed to hook directly to the speaker and microphone jacks of a handheld radio.

=====TinyTrak=====

----

Byon Garrabrant N6BG is the creator of the TinyTrak3 and other APRS related devices. They are available from [http://www.byonics.com www.byonics.com]. Also available is the TinyTrak3Plus which has a larger voltage regulator onboard to power a GPS receiver. The tinyTrak SMT uses surface mount components and is much smaller. Unfortunately, the PocketTracker is no longer available because some components are no longer available.

The TinyTrak3 is a "transmit only" device. It is capable of [[SmartBeaconing]] and [[CornerPegging]], plus it can send compressed beacons in Mic-E format.

MicEncoder

2008-11-24T18:02:39Z

Glenn: +Category:Hardware

Mic-Encoder use with a voice repeater.
The mic-encoder is a device that sends a 1/3second APRS data burst at the end of a voice transmission. It is like the "roger beep" some CB'ers use.

=====Mobile MIC Encoder Hardware=====
TAPR has discontinued the original [http://www.tapr.org/kits_mic-e.html mic encoder], however the [http://www.byonics.com/tinytrak/ tiny track] and [http://n1vg.net/opentracker/ opentracker] devices are in production and may be wired and configured to send position data at the end of a voice transmission. These devices can be programmed to send positions at the end of a voice transmission but not necessarily every voice transmission.

For example, a mic encoder device can be programmed to send a position report every 3 minutes - but only at the end of a voice transmission. When the radio operator keys up to talk for the first time, a data burst will be sent at the moment the PTT is released. He can key the radio up several more times and no additional burst will be sent until more than 3 minutes have passed since the last data burst. The mic encoder unit will not key up on it's own at the end of 3 minutes and force a position. This completely eliminates the posibility that a packet burst will blindly "double" with another active voice user. If the encoder is programmed to send a position at a shorter interval, such as every 10 seconds it will transmit a databurst every time the radio unkeys. The mic-e will never cause a "double" with another repeater user, nor will it send a data burst over the top of the radio operator's voice while he is talking.

=====Methods to convey MIC Encoder data bursts to the APRS frequency=====
This data burst can be read by any station listening to you direct or via the output of a repeater you happen to be talking through.

*Method 1
The simplest way to these position reports from the repeater to the normal aprs frequency of 144.39 is to place a police scanner within range of the repeater connected to a TNC. The TNC is configured to recieve audio from the police scanner or other receiver and transmit to a 2m transmitter. The TNC upon hearing the packet on the police scanner (or other receiver) will digipeat the packet out on the normal APRS frequency. It is recommended that the deviation level of mic-e packets be kept very low so the unmuted packet tones don't "blast" anyone listening to the repeater.

*Method 2*
Even though the data bursts are only 350mS long, after some time data bursts on the output of a repeater will begin to annoy some voice users. If the repeater is properly equipped, the data can be muted, and repeated to the standard APRS frequency (usually 144.39 Mhz) unbeknownest to the normal voice repeater users. If implemented on a nationwide level, this would allow all APRS users in the country to see all mobile aprs equipped cars.

The ideal TNC to use at the repeater site is presently the Kantronics [http://www.kantronics.com/products/kpc3.html kpc3plus]. By issuing the command "CTRL A MUTE 10" you can cause radio port pin 8 to become a mute pin to mute audio on your voice repeater. A kpc3(nonplus) model can also be made to perform the same function with a relatively minor hardware modification. The newest KPC3+ model has version 9.1 firmware, but the MUTE function has been available since version 8.3. Either firmware supports analog inputs, digital outputs, and advanced APRS digipeater functions. This makes it possible to send telemetry from the repeater site in addition to APRS position data.

PACCOMM brand TNCs have had this ability for some time now as long as they have the true DCD board installed. This has been known to false though and could mute someone's voice at the wrong time - just as some people's voices cause the DTMF cover tones to activate on a voice repeater.

The DCD or MUTE signal can be tied to the repeater receiver audio or the COR signal. The COR signal is the preferred method because many repeater controllers have audio delay processors and can mute the audio before even the first millisecond of packet data is passed to the repeater output frequency. If the repeater is not equipped with an audio delay line, the 10mS of packet will sound similar to the "blip" heard before a DTMF cover tone sounds.

There are two common methods to interrupt the COR signal: 1) with a reed relay, 2)by installing a 100ohm resistor in series between the receiver and repeater controller and allowing the TNC to clamp the repeater controller end of the signal to ground or Vcc. Since many repeater controllers such as the CAT1000 use a DB25 plug for the interface between the radio and the repeater controller, a rs232 db25 breakout box with a db25m at one end and a db25f at the other. Radio shack used to sell these for about $10, but have discontinued them. One alternative is [http://www.cablesandconnectors.com/PIX/phi23.jpg http://www.cablesandconnectors.com/PIX/phi23] near the bottom of the page.

http://info.aprs.net/images/cat1000.gif.png

Is is necessary to install a 2m radio at the repeater site with a small 5/8 or 1/4 wave antenna on the roof of the repeater shack. Care should also be taken to provide a squelch indication from the 2m radio to the external carrier detect (XCD) pin on the TNC. This will allow the TNC to hold off digipeating the mic-e packet into the APRS frequency until that channel is clear.

*Additional Notes
In addition to the first example listed above, the mic encoder units can be programmed to wait for quiet time on the repeater and automatically send a position every 10 to 30 minutes even if the user doesn't manually key up his radio. If the repeater controller's COR signal is used to mute audio, users can sent positions via the repeater all day long without activating the repeater output!

Consider that the average repeater has a "kerchunk" filter that requires the COR is active for 0.5 sec before the repeater will wake up from a dormant state. If a mic-encoder device keys up and transmits a packet to a repeater with COR muting, within 10mS of packet starting, the TNC at the repeater site will cause the COR line to drop. This happens within 10mS of the beginning of the packet. The repeater controller will see COR go active for 10mS, and drop. The repeater controller thinks it was kerchunked, and does not activate the repeater output. Since the repeater output was not activated, no one listening to the output of the repeater is aware that any data was sent on the input frequency. In effect, the packet is silently diverted over to the normal APRS frequency.

It gets better! Many TNCs today perform callsign substitution when digipeating. If the callsign of the TNC at the repeater site is set to the frequency of the repeater - up to 6 characters - then any packet passing though the repeater will be marked with the voice repeater's frequency. For example, by setting the callsign of the TNC to 147015, any packet digipeated via the input of the repeater has the text 147015 added to it's path and it is clear to APRS users that 1) this position was from a mic-e packet, 2)the user is monitoring the 147.015 repeater. If the user QSY's to another mic-e capable repeater, the TNC at that site will add it's own stamp to the APRS packet. Because the frequency stamp information is added at the repeater level, the voice user does not have to make any changes to his mic encoder device. Other APRS users are instantly aware of the station in question's frequency.

PocketTracker

Glenn: +Category:Hardware

The PockeTracker incorporates a TinyTrak PIC IC and a VHF Dual-frequency 270 mW transmitter. It was a product of [http://www.byonics.com/ Byonics], but is no longer available.

PocketTracker has an option in the later model to change the frequency of the transmitter by talking directly to a divide-by network.

In the previous model the frequency of operation was fixed between two different known frequencies via a jumper.

The main advantage of the PocketTracker is its low power consumption and its size. It can run for something like 100 hours on a 9Volt battery. It was housed inside an Altoids tin, requiring only an external antenna and a GPS connection for operation.

The PocketTracker has been discontinued because some of the parts it requires are no longer available. [http://www.byonics.com/ Byonics] now offers a different product, the [[MicroTrak300]].
