APSPOT

Getting Started

APSPOT supports a number of commands, and depending on what command is sent will depend on how APSPOT responds. To get started with APSPOT, simply send a message “usage” to APSPOT on APRS and as long as you have gone in via a Tx-Enabled APRS IGate (Or you were heard by a Tx-Enabled APRS IGate) the system will reply with a number of messages on how to use the system.

The Commands

“usage” Replies with the list of usage types of the system.

“usage <type>“ Replies with basic usage information for each type within the system. Valid types are “aprs”, “sms” and “winlink”

Examples: usage aprs, usage sms, usage winlink

“usage <type> <activity>“ Replies with an example message for your activity.

Example: usage aprs sota replies with: EXAMPLE: "! SOTA VK3/VN-030 7.090 CQCQ"

Getting Current SPOTs

“spots <activity>“ Replies with the 3 (SMS/APRS) or 10 (Winlink) most recent SPOTS under the activity you provide. Currently the system supports POTA (from pota.app), SOTA (from parksnpeaks.org) and WWFF (from parksnpeaks.org).

Example: spots POTA would return 3 messages via APRS:

K0DME | K-1210 | 14057.0 | CW
N9FAL | K-2234 | 14287 | SSB
B3WAV | K-7724 | 14294 | SSB

“spots” Filter Options

The “spots” command has a couple of filtering options:

Filter by mode: Add the desired mode onto the end of the command

• spots pota cw – will return CW POTA spots
• spots wwff ssb – will return SSB WWFF spots

Request more spots: Add a number onto the end of the command

• spots wwff 5 – will return a maximum of 5 WWFF spots via SMS and APRS

Combine filters: The mode filter must be specified first

• spots wwff ssb 5 – will return up to 5 SSB WWFF spots

Note: If less than the requested amount of spots are available for the given request – only the available spots will be returned.

Posting a SPOT

APRS Format:

! <Activity> <Ref> <Frequency In MHz> <Mode> <Comment(Optional)>

Winlink Format (Place in Subject of message):

! <Activity> <Ref> <Frequency In MHz> <Mode> <Comment(Optional)>

SMS Format:

!<Callsign> <Activity> <Ref> <Frequency In MHz> <Mode> <Comment(Optional)>

Note: For SMS Spotting, please append your callsign immediately after the “!” WITHOUT a space.

Format Breakdown

• ”!” – Tells the system that you’re submitting a SPOT
• ”<Activity>“ – Currently supported: WWFF, SOTA, POTA, SIOTA
• ”<Ref>“ – Reference of the Park/Summit/Silo (e.g., WWFF-1929, VK3/VN-008, VK-3024)
• ”<Frequency in MHz>“ – Frequency in MHz (e.g., 7.144, 14.310)
• ”<Mode>“ – Supported modes: SSB, CW, FM, AM, DATA (plus FT8 for POTA)
• ”<Comment>“ – Optional comment (include “test” to prevent actual posting)

Example Messages

APRS & Winlink: For APRS send the message to “APSPOT” in the callsign field For Winlink send the message to “apspot@apspot.radio” and place the command in the SUBJECT line.

Examples:

• ! WWFF VKFF-1929 7.144 SSB CQCQ
• ! POTA VK-3024 7.195 SSB CQCQ

Usage

Send a message to TIME with a location or time zone:

TIME <location>

Examples:

• TIME New York
• TIME London
• TIME UTC
• TIME PST

The bot will respond with the current local time for the requested location.

PING

PING is a simple connectivity test bot that responds to confirm your APRS messaging is working properly.

Usage

Send any message to PING and it will respond back, confirming your APRS path is functioning:

PING test

This is useful for testing your APRS setup and verifying message delivery.

REPEAT

The REPEAT bot is a handy tool for finding information about amateur radio repeaters. Simply provide a location or grid square, and REPEAT will return details like frequencies, tones, and offsets for nearby repeaters.

Usage

Send a message to REPEAT with your location or grid square:

REPEAT <location>

Example: REPEAT EM12

ISS

If you’re interested in satellite communication or just want to know where the International Space Station (ISS) is, the ISS bot has you covered. It provides the current location of the ISS, including its latitude, longitude, and altitude.

Usage

Send a message to ISS to get the latest position:

ISS

CQSRVR

CQSRVR is an APRS server designed to facilitate initial contact between amateur radio APRS stations (hams) worldwide with similar interests. It is not a messaging server, BBS, or any other type of interactive forum. It is a global service and requires unique callsign-SSIDs to be used.

Basic Usage

To use CQSRVR, send an APRS numbered message to CQSRVR that looks like:

CQ groupname your message here

“CQ” and “groupname” are each one word separated by a space, and may be any mix of upper and lower case. “your message here” is the message text you want to be sent to other registered members of “groupname”.

Example

AE5PL-10>APRS::CQSRVR   :CQ MYTEST Listening for APRS contacts{01
CQSRVR>APJIC1,TCPIP*::AE5PL-10 :ack01
CQSRVR>APJIC1,TCPIP*::AE5PL-10 :Message has been sent to MYTEST{00
AE5PL-10>APJIC1,qAO,CQSRVR::W5EJL-1  :CQ MYTEST Listening for APRS contacts

Registration and Limits

Every time you send a CQ groupname message to CQSRVR, it “registers” you with that group. You may only send one CQ groupname message per 30 minutes to keep activity manageable.

Unregistering from a Group

To unregister from a group, send a numbered APRS message to CQSRVR with:

U groupname

Example: U MYTEST

If the group is inactive for 12 hours or you are inactive for 12 hours, you will be unregistered automatically.

Other Commands

• ? - List all active groups
• ? GROUPNAME - Reply with how many are in the group
• L - List all groups I am a member of

These commands are sent just like the CQ and U commands (the text portion of an APRS message to CQSRVR).

EMAIL

EMAIL Server (EMAIL)

The easiest way to send email is to send a message to EMAIL with the recipient’s email address as the first “word” of the message. You may only send one line messages (67 total characters maximum).

Send APRS message "email@address message text" to EMAIL.
APRS Format: URCALL-10>APRS::EMAIL    :urname@urdomain.bogus This is a test.

Note: Keith Sproul WU2Z retired the EMAIL server in 2019. It has been replaced with a javAPRSSrvr Email Gateway (EMAIL-2).

javAPRSSrvr Email Gateway (EMAIL-2)

javAPRSSrvr supports email via EmailGate. This server supports the EMAIL method of sending email and supports some new features. EmailGate now properly supports UTF-8 in both APRS messages and emails.

Currently, EMAIL and EMAIL-2 are the callsigns for the general email servers. Both support delayed delivery of APRS messages and messaging to/from Winlink.

Creating Shortcuts

To create a shortcut:

Send APRS message "shortcut email@address" to EMAIL-2
APRS Format: URCALL-10>APRS::EMAIL-2  :me urname@urdomain.bogus

Using Shortcuts

To use the “me” shortcut from any of your stations:

Send APRS message "shortcut message text" to EMAIL-2
APRS Format: URCALL-7>APRS::EMAIL-2  :me This is a test.

Managing Shortcuts

List all shortcuts:

Send APRS message "shortcut L" to EMAIL-2

Remove a shortcut:

Send APRS message "shortcut R" to EMAIL-2

Note: Shortcuts are associated with the callsign so each amateur can have their own shortcuts. They can only include alpha and numeric ASCII characters (no punctuation, white space, or Unicode characters).

Email to APRS Support

Shortcuts may be used by persons on the Internet to send an APRS message to a station via email. The email must meet these requirements:

1. Must be from the email address specified in the shortcut
2. Subject must start with the station callsign-SSID (all upper case) followed by a colon and message text
3. Body must contain the text “userid:shortcut:” where “shortcut” is the assigned shortcut

Example Email to APRS

From: urname@urdomain.bogus
To: EMAIL-2 email address
Subject: URCALL-10:Testing email to APRS.
Body:
This is a test userid:me: of APRS email gateway.
Your Name URCALL

Undelivered Message Caching

Some javAPRSSrvr email gateways support unacknowledged message caching. If a valid email goes unacknowledged after 4 tries, you may retrieve cached messages by sending:

Send APRS message "get" to EMAIL-2
APRS Format: URCALL-10>APRS::EMAIL-2  :get

The ?APRSM query is equivalent to the get command.

EMAIL-2 supports caching for up to 24 hours and supports both the get command and ?APRSM query.

This guide covers the major APRS bots available for amateur radio operators. Each bot provides unique functionality to enhance your APRS experience. Happy operating!
