The RX-SPECIAL synthesized receiver covers any continuous 4MHz frequency spread between 148.000 MHz and 174.000 MHz. The system includes a folding Yagi antenna which mounts directly to the receiver. The receiver is nicely balanced on the antenna for comfortable, one handed operation.
The RX-SPECIAL is extremely sensitive to hear the weakest telemetry signals, it also employs very effective filters to eliminate unwanted interference sources. The synthesized design provides excellent temperature stability with no drift in frequency settings. A four step attenuator allows full receiver sensitivity for longest range or reduced sensitivity for extremely close-in tracking to a few inches. It employs a large, full range, speaker for rich sounding loud audio. A very sensitive signal strength meter also doubles to let you know when the battery needs replacing. A rugged, light weight, aluminum case is standard as well as a 3.5 mm mono headphone jack. A standard circ., 5.5mm x 2.1mm, center positive, power jack allows the RX-SPECIAL to be powered from an external 9-14VDC source. Select range of 4.000 MHz from 148.000 MHz to 174.000 MHz.

This receiver is an exceptional value for a synthesized receiver covering any frequency between 216.000 and 222.000MHz with no gaps in coverage. This not only allows you to hunt with multiple birds transmitting at the same time, but multiple dogs also. The R-600A is supplied with a folding high gain, and very directional antenna which mounts directly to the receiver and rivals a Yagi in performance. No coax is required, allowing one handed operation. A standard 9 volt alkaline battery powers the unit and is easily changed using a fingernail. Not only is the R-600A extremely sensitive to hear the weakest telemetry signals, it also employs very effective filters to eliminate unwanted interference sources. The synthesized design provides excellent temperature stability with no drift in frequency settings. A four step attenuator allows full receiver sensitivity for longest range or reduced sensitivity for extremely close-in tracking to a few inches. The R-600A employs a large, full range, speaker for rich sounding loud audio. A very sensitive signal strength meter also doubles to let you know when the battery needs replacing. A rugged, light weight, aluminum case is standard as well as a 3.5 mm mono headphone jack and adaptor for the larger 1/4” headphone plugs. A standard circ., 5.5mm x 2.1mm, center positive, power jack allows the R-600A to be powered from an external 9-14VDC source.

Power Output: Set to use available battery power over the required transmitter life.
Housing: The transmitter and battery are encapsulated in an inert waterproof epoxy. Battery placement determines shape. Several mounting options are available (see below). Although the unit is usually glued to the animal (click here for gluing instructions), one or two tubes can be attached for the passage of sutures or harness material (click here for harnessing instructions). Tubes will increase the total weight by 0.05 to 0.1 g. The unit can be attached to a bird leg-band (supplied by researcher). Extra potting is required for implanted transmitters, for use in high ionic environments (e.g. alkaline, saline), for extra waterproofing, or for abrasion resistance where needed. This will add ~0.1 g.
Examples of tube placement: Tubes will slightly increase length and weight (0.05 – 0.10g) of the finished transmitter.
One anterior tube for a light harness or belt.
One center tube for a light harness or belt.
Two tubes (anterior and posterior) for sutures or harness material.
Two pairs of vertical tubes and molded longitudinal groove for single feather tail-mount attachment.
Antenna: A stranded stainless steel wire covered with a black or brown nylon coating, or a 0.18mm (0.007″) stainless steel wire. Shrinkable tubing can be added to reinforce the base of the antenna. Helical antennas can be added to allow for implantation (see photos below).
Helical Antenna Configurations: All of the sizes listed above can be fitted with helical antennas to allow for implantation. This will add ~0.1g to the finished weight and 2mm to the height (Internal Helix) or 10mm to the length (External Helix). Please note: Due to the reduction in reception range, this configuration should only be used in cases where a subcutaneous antenna is not possible. There are two available options:
Internal Helix (suffix “H”): In this configuration, the helical antenna is placed across the top of the unit and encapsulated within the potting material. Range under normal conditions: 50-100m.
External Helix (suffix “HX”): In this configuration, the helical antenna is coiled around a 10mm piece of Tygon tubing, which extends beyond the back of the unit. Range under normal conditions: 100 – 200m.
Activation: Removing an external magnet starts the transmitter. Replacing the magnet stops the transmitter.
Position (suffix “P”): The pulse rate switches from ~24 ppm in a vertical position to ~50 ppm in a horizontal position. This option adds ~0.5g to the finished weight of the transmitter.
Temperature (suffix “T”): An increase or decrease in temperature results in a corresponding increase or decrease in pulse rate. At the standard settings, the pulse rate changes from ~25 ppm at 0°C to ~40 ppm at 40°C. Each transmitter is supplied with a plotted calibration curve. This option adds ~0.05g to the finished weight of the transmitter.
