QUICK! — GET ME ON THE AIR!
If this is your first Model 37-MAX Repeater Pal, your first questions probably are “What do I
have to do to enable a tone?” and “Do I have to understand all the features just to make it
work?” Here are the answers:
Before you can work with the Model 37-MAX, it must be installed. FOLLOW THE
INSTALLATION INSTRUCTIONS (see Section 5). The installation should be accomplished
by a qualified radio service technician. Then get your transceiver (set on the repeater's
frequency and with touch-tone keypad) ready to enable some tones.
ACCESS THE PROGRAM MODE
To access the program mode, key up and press “12037”. A chirp should be heard coming
back from the repeater (the chirp, or five beeps, is the “go-ahead” prompt tone). If the
program mode is not accessed, check the Status LED on the front panel to see if it flashes
with every key pressed.
PROGRAM MODE PROMPT TONES
During programming, the Model 37-MAX will issue prompt tones to indicate how it’s doing.
A “warble” or “dee-doo dee-doo dee-doo” tone indicates an invalid command or that an error
condition exists. A “chirp” or “bip bip bip bip bip” (five quick notes) indicates the proper
completion of a command. A double “bip” indicates the panel is ready for additional digits to
be entered to complete a command. When exiting the program mode, a “ringing” sound will
be sent to verify the exit. If a key is not pressed within 60 seconds, the Model 37-MAX will
exit the program mode automatically.
ENABLE A CTCSS TONE
A CTCSS tone may be enabled by pressing “111# nn#”, where “nn#” is the tone number
from the User Numbers versus CTCSS Tones table in the Quick Reference section at the end
of this manual.
PROGRAMMING EXAMPLE
Enable CTCSS tones 67.0, 100.0, 127.3, and 186.2:
1. Access the program mode. Press “12037”, then listen for the five beeps.
2. Enable the tones.
for 67.0 H (tone 1), press 111# 1# (five beeps heard)
for 100.0 H (tone13), press 111# 13# (five beeps heard)
for 127.3 H (tone 20), press 111# 20# (five beeps heard)
for 186.2 H (tone 36), press 111# 36# (five beeps heard)
3. Exit the program mode. Press 99#, then listen for the ringing sound to verify exiting.
4. Test the repeater!

1. INTRODUCTION
OVERVIEW
The Zetron Model 37-MAX Repeater Pal is a high capacity, remotely programmable,
community repeater controller. It provides individualized repeater service to up to 154
different customer groups using CTCSS tone and Digital Coded Squelch (DCS) signaling.
The Repeater Pal connects to a receiver and transmitter providing CTCSS/DCS decode,
regenerated CTCSS/DCS encode, repeat audio processing, selectable system functions and
per-user functions. It will convert any station capable of full duple operation into a fully
featured community repeater. The Repeater Pal is an ideal replacement for older tone panels,
eliminating time consuming trips to remote repeater sites, as well as providing a high
subscriber capacity growth path for the future.
The compact size of the Repeater Pal is ideal for low power repeater packages constructed
from a pair of suitable mobile radios.
Complete CTCSS/DCS Coverage
The Repeater Pal has the capacity for supporting up to 154 separate user groups on a single
channel, which is ideal for scan based trunking systems, roaming, or seasonal users.
The panel is equipped with ToneLock decoding, an e clusive Zetron feature that eliminates
dropouts resulting from weak, fading signals or high modulation levels. The usable range of
the repeater is not limited by the decode performance of the repeater tone panel when the
Repeater Pal is in control.
The 37-MAX recognizes when a subscriber unkeys with a reverse burst, or the DCS turn-off
code, and silently mutes the repeat audio path to prevent bursts of “squelch tail” noise from
being repeated on the channel. The Repeater Pal also supports squelch tail elimination by
dropping its encode a short time before dropping its carrier when the station is unkeyed. This
ensures that listening radios mute without any annoying noise burst.
High quality audio processing circuits in the Repeater Pal are designed to make its repeater’s
audio quality rival the very best panels on the market.
Features You Expe t in a Zetron Panel
Aside from providing the decode and encode performance of a larger tone panel, the Model
37-MAX has many of the other features of the “big guys” as well.
The Morse code Station ID feature is fully field programmable. The ID call sign can be up to
eight characters in length. The panel can be set to wait for the ne t transmission to ID or to
ID automatically whenever the ID interval timer reaches zero. The duration of the ID interval
is also field programmable, as is the speed at which the ID is sent.
Section 1. Introduction
1-2
A Courtesy Beep, to inform listening mobiles that the speaker has definitely unkeyed, is
available on a per tone/code basis. The pitch of the Courtesy beep is also programmable (on a
system-wide basis) to either 500 Hz, 1000 Hz, or 1500 Hz.
The Reserved User feature helps to prevent the loss of tones or codes to co-channel operators
during periods when they are temporarily not in everyday use. When a tone or code is
programmed as ‘reserved’, the Repeater Pal will mute its repeat audio and transmit an alert
tone on the channel.
The Cross Tone encoding feature e pands the uses to which the panel can be put, allowing it
to support applications that require the panel to encode a different tone or code than it
received.
Programming and Control
In order to make it easy to install and easy to maintain, the Model 37-MAX is designed to be
programmed over the radio channel using any mobile or handheld capable of manual DTMF
encoding. If you wish to, you can use a Zetron Model 8B Repeater Programmer/Timekeeper
attached to a control station or mobile radio.
This programming method was chosen for two very good reasons. First, because it doesn’t
require the installer or maintenance technicians to have special equipment in order to
program the repeater; they can use equipment they already have. The second reason is that
you don’t have to be physically at the site in order to program the repeater. All the technician
needs to be able to do is to drive far enough into the repeater’s service area to be able to
reliably hit the repeater while programming it. This can pay real dividends when a trip to the
site is made difficult not just by distance but by accessibility as well.
Installation and Setup
Easy installation and setup procedures ensure that a technician can install a Model 37-MAX
in nearly any repeater or duple station. Only seven connections are required in typical
installations, and interfacing assistance is available from Zetron. Section 5 includes
application notes for some of the more popular repeaters, such as:
GE MASTER III, MASTER II, Custom MVP, EXEC II, MASTER PRO
EF Johnson Viking Universal Station, CR1010, CR1000
Kenwood TKR720, TKR820
Midland Basetech Repeater
Motorola GR300/GR500, R100, MSF5000, MSR2000, MICOR
