TR-5 Telemetry Scanning-Receiver
with Optional Data Acquisition System

The information below on discontinued products is provided for individuals who are still using these older systems. Product descriptions may be time sensitive or even outdated. Please contact Telonics if you have questions.

The TR-5 Telemetry Scanning-Receiver is designed for use with conventional VHF transmitters and is capable of receiving and processing signals in the 140-230 MHz frequency range. The TR-5 has a standard 4 megahertz frequency range specified. A 6 megahertz version is available as Option 030 (6MHz). TR-5 is designed to receive and process the type of RF signal transmitted by a radio frequency (RF) beacon, i.e. a continuous wave signal with pulse interval (period) modulation consisting of a series of pulses of short duration ( 12 to 255 millisecond duration) separated by a period of time in the range of 0.100 to 9.900 seconds. This transmission format is used in most conventional VHF wildlife transmitting subsystems used for tracking applications. The TR-5 can be operated from its internal battery (8 AA Alkaline pack is standard) or externally powered from either a RP-2 AC power supply or a PS 007248-001 DC power cord attached to any 12 to 18 VDC source (such as a car battery).

Modes of Operation

The TR-5 has four fundamental modes of operation:

  • Manual Mode (standard). The receiver is under direct user control during operation. In this mode of operation, the frequency of interest is entered into the receiver using the keypad. Delta tune, gain, and volume are also under direct manual control.
  • Scan Mode (standard). As in the Manual Mode, the user has complete control of the receiver's delta tune, gain and volume. In addition, the receiver has the ability to step through multiple frequencies, dwelling for user specified periods on each frequency. The user can enter the frequency information and dwell times directly using the keypad of the TR-5 or the on a PC utility called the TR-5 interface program supplied in the TR-5 KIT. This file can be edited, saved, modified or downloaded to the TR-5. This is the easiest method when entering more than a few frequencies. When transmitters are detected, the user may choose to pause on the current frequency indefinitely by pressing the PAUSE key. When the user is satisfied, scanning can be resumed by pressing any of three different keys. Any frequency may be removed from the scan sequence; however, the actual frequency is not lost from memory and all frequencies in the memory may be restored to the scan sequence. An additional feature has been developed to search for transmitters which are slightly off frequency. Before the scan sequence is initiated by the user, three options are made available: scan only the designated or base frequencies in the scan list or utilize the Expanded Search Mode by searching +/- 1 kHz from the base frequency or +/- 2 kHz from the base frequency. Internal memory on board the TR-5 is capable of storing 255 individual frequencies for scanning. Frequencies can be assigned to groups and a priority scan sequence can be established and modified while the receiver is in use.
  • Data Acquisition Mode (Option 320). This TR-5 option can be installed and enabled by the factory either at the time of purchase or at a later time when the user requires this special function. Allows the receiver to scan, detect, acquire, and archive telemetry data while operating in either an attended or unattended mode. Every qualified pulse and associated interval is date and time stamped and stored in the TR-5's data base. The archived telemetry data can be retrieved from the TR-5 using a PC and Telonics' proprietary program. The memory available for data storage consists of 4096 bytes of non-volatile EEPROM and 1 megabyte of static RAM. In the data acquisition mode, this memory is capable of holding 153,000 data records associated with a frequency, pulse period, date and time of acquisition.
  • Utilities Mode (standard). In this mode, the researcher can accomplish those tasks that support the other modes but are distinct from them. An example is the transfer of files generated on a PC for support of the Scan or Data Acquisition Modes of operation.

The TR-5PI Parameter Interface is a utility program with several unique features which aid in setting up the TR-5 for operation in the Scan Mode and the Data Acquisition Mode. Although all functions of the TR-5 receiver-scanner can be entered or modified from the integral keypad on the TR-5, the Parameter Interface provides a means of interfacing the TR-5 directly to your PC. This Windows utility allows the researcher to program frequencies to be scanned into the TR-5. Additional information about the transmitters i.e. pulse width and pulse periods used in the data acquisition mode (Option 320) can also be easily entered into the TR-5 through this program. In addition, data collected during the data acquisition can be downloaded using this utility and output to various file formats for later incorporation into a user's GIS.


The TR-5 and related equipment may be purchased individually or as a package. The TR-5 Kit includes the following items:

TSC-1 Programming Cable. A DB9 male to DB9 female cable used to transfer parameters and data file between the TR-5 and user PC

TR-5 Data Acquisition System

The TR-5 can be configured into a complete data acquisition system. The entire system can be deployed in the field to receive and data log telemetry data on a continuous or scheduled basis. The transmitter frequencies, date, time, pulse period, signal strength are logged into memory for later downloading by the researcher. The system operates in a fully unattended mode for the collection of any pulse coded data such as temperature, heart rate, activity level, mortality or simply presence or absence information. The system collects any data encoded into the pulse period of the transmitter but does not collect bearings or positional data. To function as a data acquisition system the following components are recommended and must be procured separately:

TR-5 Kit
Option 320 Data Acquisition Option
RC-9 Instrument Case
RP-7 Field Power Pack
RP-14-110 110-120 VAC Wall Charger for the RP-7


An appropriate antenna and coax cabling must be procured separately. Most system users select an omni-directional antenna such as the RA-6B, RA-10, or RA-5A (see section on receiving antennas for fixed stations. The appropriate coax cable length and connectors must be selected.

Note: The researcher may substitute power supply options or provide alternative antennas or waterproof enclosures for the equipment listed above. The researcher using this approach must integrate the components. The information provided describes a complete system ready to go to the field without the requirement for the researcher to provide any additional components or complete any integration.
