All systems are open for general use. A PL tone of 110.9 Hz is generally required on the W8GQN VHF repeater to avoid interference with another nearby repeater. There is, however, a bypass code (*00) that will temporarily remove the PL tone requirement and permit access by users who don't have PL tone capability. Users are encouraged to use this code and distribute it freely.
Many features of these repeaters are available for use by anyone within range of the repeater and there is on-line help available to assist users with those features. Other features are available only to registered users. Registration is not intended to restrict use of those features, but rather to enable use of those features. Registered users are encouraged to demonstrate those features for others and may activate and operate them for non-registered and transient users.
The system has been designed and programmed to be as easy to use as possible. It is, however, still a work-in-progress and users are encouraged to ask questions and suggest changes and improvements. Questions and suggestions should be submitted to Chuck Scott N8DNX via E-Mail at info@n8dnx.org.
Repeater Operation and Etiquette
Users should keep in mind the following items when using these repeaters.
- Keep transmissions relatively short. The repeater will timeout after 3 minutes.
- Wait for the "courtesy beep" before starting your transmission.
- Users who want to break into a conversation should simply say "Break" prior to the courtesy beep.
- Users who want to break into a conversation with priority or emergency traffic should say "Break, Break, Break" prior to the courtesy beep, then wait to make sure their priority transmission doesn't "double" with another users transmission.
- Emergency and health and welfare traffic always have priority over other communications.
- It is common courtesy to permit other users to join a conversation.
- It is impolite to break into an ongoing conversation for the purpose of initiating a separate conversation with another station.
- It is impolite (and frankly illegal) to "kerchunk" (key up) the repeater without ID'ing.
- Users should not acknowledge, intimidate or otherwise argue with any user who intentionally interferes with or attempts to disrupt repeater operations. Please report all such offenses to a system operator or club officer via telephone or on another frequency.
- Always be polite, courteous and helpful to all other users of the repeater.
Registered User Security
Registered users are issued a "User Number" and a "Pass Code". Your user number is public information. It enables other users to send you private voice mail over the repeater. Your pass code is not public information and you should not share it with other users of the repeater. If you believe that someone else has decoded your pass code and may be using it, the system operator can issue you a more secure type of pass code that can't be determined by monitoring your transmissions on the input frequency.
On-Line Help System
The repeater system has an "on-line" help system that lists many of the more common commands user may need. The help system is divided into a number of sections including system description and general help, and individual descriptions for each logical group of commands. User may enter "999" to access the main system information and help overview message. All system information and help messages are "polite announcements" in that they stop when the repeater receives a transmission. This permits a user to stop the transmission as soon as they've heard the information of interest by briefly keying their transmitter.
User Command Descriptions
All user commands are entered using the numeric keypad on your radio while you're transmitting into the repeater. Not all commands are can be used by all users. The "User Level Required" field in the command descriptions below indicates the user level required to execute each command.
Before you can execute any command that requires user level 1 or higher, you must first log into the repeater using your user number and pass code (see command 71). You do not need to log into the repeater to use any level 0 command.
Each registered user is assigned a "User Level". The user level you are assigned depends on whether or not you are a Remote Base user or if you are a control or system operator. If you are a Remote Base user, your user level is determined by the class of your Ham Radio license.
User Level Description 0 All users, no user registration or user number/pass code are required. 1 Registered user 2 Technician Class Remote Base users 3 General Class Remote Base users 4 Advanced Class Remote Base users 5 Extra Class Remote Base users 6 Control Operators 7 System programming
The curly braces "{" and "}" in a Command Code indicate that the user is to include other variable digits along with the command. For example, the command ...
- * {PhoneNumber}
Entering an incorrect command code, attempting to enter a command from a repeater port on which the command is not available, or entering a command you are not authorized to use, may result in either no response from the repeater or an error message. While some error messages are given by voice announcement, most error messages are given by number. The following table lists possible numeric error messages and their meaning.
Error Number Description Error 200 Command not found Error 201 Too few data digits entered Error 202 Too many data digits entered Error 203 ncorrect number of digits entered Error 204 Command not allowed from this repeater input Error 205 You do not have permission to use this command Error 210 Incorrect digits entered for this command Error 212 Bad Autopatch Number Error 213 General Autopatch error Error 214 User log-in is disabled Error 215 Digital Voice Recorder is busy Error 217 Bad command entered in Remote Base mode
IRLP - Internet Radio Linking Project
The "Internet Radio Linking Project" (IRLP) is a cooperative project to link distant Amateur Radio stations and repeaters (nodes) over the Internet. IRLP permits the operator at one node to select, and connect to, any other available distant node by entering specific commands. Once connected, radio users within range of either connected node can enter into a QSO as if they are all using the same local repeater. IRLP nodes are located all over the world and as such provide an opportunity for DX, of sorts, for local users. Currently, there are more than 275 nodes, many in North America, but a number scattered across the world.
Note: You do not need a higher-class license to use the IRLP system. If your license permits you to use a repeater, then you are permitted to use IRLP.
A status page with a list of nodes and status of each is available over the Internet at http://status.irlp.net.
A four-digit number designates each node. The on-line status page lists the node number, call letters, location, last status update and present status of each node. The preset status will be one of the following values.
DOWN Node is currently out of operation or unreachable IDLE Node is operational and available for a connection REF# Node is connected to an IRLP reflector. Connect to that reflector to contact users of the node. {anything else} The call sign or name of another node to which it is connected-the node is unavailable.
Reflectors are central servers that permit more than 2 IRLP nodes to connect to each other at one time. These reflectors permit a "round table" of sorts between users of 2 or more nodes. You may connect to a reflector just as you would to any specific node. The only difference is that you never know where you may reach or whom you may contact!
You connect to a remote node or reflector by entering a command prefix (38) followed by the number of the node. To disconnect from any IRLP node, use "38 73".
38 {nnn} Connect to node number {nnn} 38 73 Disconnect from any node
38 4460 Connect to node 446 in Southfield (talk to stations in Southfield) 38 73 Disconnect from node 446 in Southfield
Users of other IRLP nodes may also connect to our IRLP node. If any call from another node comes in while IRLP is not connected to one of the repeaters, the IRLP system will automatically connect to the W8GQN VHF repeater and the incomming call will be heard there.
Note: The following are special commands to the IRLP node. These commands are unique to the IRLP node on our system and will not function on other IRLP nodes. These do not connect to other IRLP nodes. Instead they perform functions local to the IRLP computer, such as playing an ARRL News recording.
38 73 Stop playing recorded audio news 38 0001 Play the most recent ARRL Audio News Bulletin (Updated late Saturday night) 38 0002 Play the most recent Amateur Radio Newsline (Updated late Saturday night) 38 0003 Play the most recent This Week in Amateur Radio (Updated early Sunday morning) 38 0101 Play Pelston Airport weather (Updated hourly - on the hour) 38 0102 Play statistics report from most receint IRLP connection 38 0103 Play Propagation report (Updated hourly - :05 after the hour) 38 0104 Play list of nearby APRS stations 38 0199 Play a silly message
Operation on the IRLP network is very similar to operation on the local repeater, with a few exceptions.
General IRLP node use guidelines:
- Be considerate and patient with other IRLP users. There are new IRLP nodes being added all the time and inexperienced users trying the system every day-try to make them welcome. Remember, you are Northern Michigan's "ambassadors" to the world.
- Do not tie up the W8GQN SAARC club repeater for extended times with IRLP operation during peak use hours for the repeater. The KO8P repeater is preferred for long-term remote base and IRLP operations.
- Assist traveling Hams with use of the IRLP system. If they've used IRLP elsewhere, they may be familiar with needing a prefix before the IRLP Node nuimber. There is no problem with informing them on how to use our IRLP Node.
- Wait 10-15 seconds after connecting to a distant IRLP node to account for transmission of the voice message on the distant IRLP node.
- Allow an extra second or two between transmissions to account for network delays.
- Include your city and state when you ID. Users of the distant IRLP node may not know you are not a local user.
- Immediately after connecting to a distant IRLP node, identify with your call, city and state.
- Identify and state that you are disconnecting before disconnecting from a distant IRLP node.
- Always permit extra time between transmissions to account for network delays and for other stations to join or leave a discussion. (Some nodes cannot disconnect when someone is talking.)
- Identify before sending any DTMF commands, such as to disconnect from a node.
- Hold your microphone PTT for about 1 second before talking to allow for network delays.
- To break into a QSO, state your call sign once during a pause in traffic.
- Don't break into a QSO simply to "work" one of the stations. Do break into a QSO to join a conversation.
- When more than 2 people are in a QSO on a reflector, try to maintain an organized "round table" format.
- Do not start a "Net" on a reflector without the permission of the reflector owner.
- If you are experiencing interference to the local repeater, disconnect from the reflector to avoid interfering with other user's transmissions.
- Keep in mind that there may at times be many users on the same reflector. Always be courteous and patient!

Remote Base User's Manual
The remote base system is capable of receiving from .1 to 30 MHz, transmitting on the HF Ham bands, and receiving and transmitting on the 50 MHz, 144 MHz, 220 MHz, and 440 MHz Ham bands using LSB, USB, AM, and FM modes. There is also a CW mode, but as there is no way to remotely key the transmitter, it's of little practical use other than receiving.
Note: There may be transmitting limitations due to the antennas connected to the remote base. As of this time, the HF transmit antenna is only useable on 20 Meters and above and there is not yet a 50 MHz antenna on the system. Expanded antenna systems are in the works and will be installed in the Spring of 2002. Please contact N8DNX for current information.
Operation of the remote base system will seem daunting at first, but you'll soon find that commonly used functions will be easy to remember and start to make sense. It's however suggested that you cut out the "Remote Base Quick Reference Guide" and have it available whenever operating the remote base.
The Remote Base and the Law
According to 97.3 (38) of the FCC rules, operation of the Remote Base is considered "Remote Control" of an amateur radio station. A remotely controlled station must be controlled using certain frequencies above 220 MHz. As such, operation of the Remote Base system is not permitted on the W8GQN VHF repeater. Remote base operation is therefore only permitted on the N8DNX UHF repeaters.
A station operating under remote control may not be "automatically controlled". When you use the remote base system, you are the control operator of that remotely controlled station. As such, you should identify the remote base using your own call letters. The proper way to identify would be "This is {your call} remote base". If you wish to be more precise, you may identify with "This is {your call} operating the N8DNX remote base". Please follow all requirements for identification when operating the remote base system.
Since you are the control operator when you operate the remote base system, you are fully responsible for its operation. Do not leave the remote base system enabled when you are not available to monitor or control its operation.
You may allow others users on the repeater to operate through the remote base while you are in control, even if their license class does not permit them to operate on the frequency or mode you have set. This is analogous to permitting someone else to talk into the microphone of your home station while you are at the controls. You are, however, fully responsible for their use of the remote base and you must properly identify the remote base operation with your call letters as mentioned above.
Turning on the Remote Base System
You will need to log into the system before turning on the remote base system. Your user ID is assigned according to your license class. When you log into the system with your ID and Pass Code, the system will know what license class you have and will limit the frequencies on which you can transmit accordingly. Once you're logged in, enter command code 50 to turn on the remote base. You cannot enter commands to the remote base system if you are not logged in!
When you turn on the remote base system, you will only be able to enter commands to the remote base system and will not be able to use the set of normal control codes. To enter normal control codes, you must first turn off the remote base.
Remote Base Command Codes
All remote base commands begin with a "7". This access digit prevents accidentally entering a short, single digit, command. The next digits of the command designate specific function and any additional digits that need to be specified.
You will note that there is some logic to how these commands are laid out on a normal Touch Tone pad. For example, all of the commands to bump the frequency down are located on the left column while all of the commands to bump the frequency up are located on the right column (with the exception of "7 A" and "7 B", isn't there always an exception). As you learn these commands, think more about their location on the keypad and less about the actual command numbers and you may find them easier to remember.
| Command: | Receive Only | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Codes to execute: | 7 1 | ||||||||||
| Description: |
Use this command to switch the remote base from receive/transmit to receive only mode.
(Transmitting into the repeater will not cause the remote base to transmit.) The remote base
will always start in receive only mode, so this command is not necessary to begin receiving
after turning on the remote base system.
|
||||||||||
| Command: | Set Radio Mode | ||||||||||
| Codes to execute: | 7 1 {mode} | ||||||||||
| Description: |
This command sets the mode of operation for the radio.
Where {mode} is: 1 = USB, 2 = LSB, 3 = AM, 4 = FM, 5 = CW
|
||||||||||
| Command: | Receive/Transmit | ||||||||||
| Codes to execute: | 7 2 | ||||||||||
| Description: |
This command places the remote base in receive/transmit mode. When in receive/transmit mode,
transmitting into the repeater will cause the remote base to transmit. To return to receive
only mode, use command 7 1.
Note: You can only select frequencies on which you are allowed to transmit when in receive/transmit mode.
|
||||||||||
| Command: | Toggle PL Receive | ||||||||||
| Codes to execute: | 7 2 1 | ||||||||||
| Description: |
This command toggles PL receive on and off. When this PL receive mode is selected, the
receiver squelch will not open unless the correct PL tone is being received.
Note: This will only work on the 50 MHz, 144 MHz, 220 MHz and 440 MHz bands when in FM mode and with PL transmit enabled (7 2 2).
|
||||||||||
| Command: | Toggle PL Transmit | ||||||||||
| Codes to execute: | 7 2 2 | ||||||||||
| Description: |
This command toggles PL transmit on and off. When PL transmit mode is selected, the remote

transmit when off, so there is no need to turn off receive/transmit mode (using 7 1) prior to
turning off the remote base system.
|
||||||||||
| Command: | Bump Frequency Down 100 Hz | ||||||||||
| Codes to execute: | 7 4 | ||||||||||
| Description: |
Entering this command will change the current VFO setting down 100 Hz. Use this command to make
small adjustments to the remote base frequency. If you are in receive/transmit mode, you will
not be allowed to go beyond the edge of the permitted transmit frequency range on the current band.
|
||||||||||
| Command: | Select VFO "A" | ||||||||||
| Codes to execute: | 7 5 | ||||||||||
| Description: |
This command selects VFO "A". The remote base system has two VFO's "A" and "B". Switching VFOs
will restore the remote base to the frequency and mode it was on when that VFO was last used.
Note: The remote base system uses separate radios for HF and VHF/UHF operation. When switching VFO's results in the remote base having to switch radios, the system will automatically turn off the remote base, reconfigure it for the correct radio, and ask you to turn it back on. (For reasons beyond the scope of this document, it was not possible to make this process fully automatic.)

This command causes the remote base to announce the current frequency, offset (if not zero),
and the selected VFO.
|
||||||||||
| Command: | Turn Off Transmit Offset | ||||||||||
| Codes to execute: | 7 8 0 | ||||||||||
| Description: |
This command will turn off any current transmit offset setting (such as a repeater offset).
After entering this command, the remote base will transmit on the same frequency as it receives.
|
||||||||||
| Command: | Turn On Transmit Offset | ||||||||||
| Codes to execute: | 7 8 1 | ||||||||||
| Description: |
This command will turn on transmit off set and use the offset frequency that was last set.
After entering this command, the remote base will transmit on a frequency that is different
from the receive frequency by the amount of the frequency offset set with command "7 8 1 x x".
|
||||||||||
| Command: | Turn On Transmit Offset and Set Offset Direction | ||||||||||
| Codes to execute: | 7 8 1 {direction} | ||||||||||
| Description: |
This command is similar to "7 8 1" except that it specifies the offset direction, either
plus or minus, from the receive frequency.
Where {direction} is: 0 = Positive Offset, 1 = Negative Offset
|
||||||||||
| Command: | Turn On Transmit Offset and Set Direction and Size | ||||||||||
| Codes to execute: | 7 8 1 {direction} {size} | ||||||||||
| Description: |
Entering this command will change the current VFO setting down 100 Hz. Use this command
to make small adjustments to the remote base frequency. If you are in receive/transmit mode,
you will not be allowed to go beyond the edge of the permitted transmit frequency range on the current band.
Where {size} is:
|
||||||||||
| Command: | Bump Frequency Up 500 Hz | ||||||||||
| Codes to execute: | 7 9 | ||||||||||
| Description: |
Entering this command will change the current VFO setting up 500 Hz. Use this command to
make small adjustments to the remote base frequency. If you are in receive/transmit mode,
you will not be allowed to go beyond the edge of the permitted transmit frequency range
on the current band.
|
||||||||||
| Command: | Select VFO "B" | ||||||||||
| Codes to execute: | 7 0 | ||||||||||
| Description: |
This command selects VFO "B". The remote base system has two VFO's "A" and "B".
Switching VFOs will restore the remote base to the frequency and mode it was on when
that VFO was last used.
Note: The remote base system uses separate radios for HF and VHF/UHF operation. When switching VFO's results in the remote base having to switch radios, the system will automatically turn off the remote base, reconfigure it for the correct radio, and ask you to turn it back on. (For reasons beyond the scope of this document, it was not possible to make this process fully automatic.)
|
||||||||||
| Command: | Write Memory | ||||||||||
| Codes to execute: | 7 5 {memory #} (Memory numbers are 1 or 2 digit 0 through 99) | ||||||||||
| Description: |
Use this command to write the contents of the specified memory into the current VFO
and set the frequency, mode, offset and other data that was stored in that memory.
|
||||||||||
| Command: | Bump Frequency Up 20 Hz | ||||||||||
| Codes to execute: | 7 A | ||||||||||
| Description: |
Entering this command will change the current VFO setting up 20 Hz. Use this
command to make small adjustments to the remote base frequency. If you are in
receive/transmit mode, you will not be allowed to go beyond the edge of the
permitted transmit frequency range on the current band.
|
||||||||||
| Command: | Bump Frequency Down 20 Hz | ||||||||||
| Codes to execute: | 7 B | ||||||||||
| Description: |
Entering this command will change the current VFO setting down 20 Hz. Use this
command to make small adjustments to the remote base frequency. If you are in
receive/transmit mode, you will not be allowed to go beyond the edge of the permitted
transmit frequency range on the current band.
|
||||||||||
| Command: | Enter Frequency | ||||||||||
| Codes to execute: | 7 {frequency} | ||||||||||
| Description: |
Use this command to set the frequency of the remote base. Use the "*" key to specify
the decimal point between MHz and KHz. If you do not use the "*" key, it will not be
interpreted as a frequency.
Where {frequency} is: MHz followed by "*" followed by KHz Examples:
Note: The remote base system uses separate radios for HF and VHF/UHF operation. When the frequency change results in the remote base having to switch radios, the system will automatically turn off the remote base, reconfigure it for the correct radio, and ask you to turn it back on. (For reasons beyond the scope of this document, it was not possible to make this process fully automatic.) Note: If the remote base is in receive/transmit mode, it will not permit you to select a frequency on which you are not permitted to transmit. To select such a frequency, use "7 1" to return to receive only mode, then select the desired frequency.

Remote Base Quick Reference Guide
The following guide is a quick reference for Remote Base commands. It is arranged to be similar to the layout of a normal Touch Tone keypad. This reference chart should make sense if you are familiar with the Remote Base commands listed above. Please use this only as a quick reference, and not as a guide to Remote Base operation.
