The Motorola GR Repeater provides the perfect solution. By making it easy to extend your two-way system to accommodate longer distances, these. NOTE: THIS IS AN ASTRON SLM POWER SUPPLY. (IN THIS CASE, THE “M” STANDS FOR MOTOROLA-. THERE ARE NO METERS ON THIS UNIT). Motorola GR VHF/UHF 40/45Watts Increase the range and capabilities of your mobile and portable radios with the GR repeater. It provides the flexibility.

Motorola Analog Base Station/Repeater: GR500/CDR500

Expect that any other radio that uses the same pin plug assembly will also have a different pinout. Look on the “Keys Page” elsewhere at this web site for a photo and the measurements. The MaxTrac and Radius power control timer can create a situation where the transmitter goes into power shutdown on motorola gr500 repeater own, which can happen in the middle of a conversation.

AMP makes a wide variety of contacts for this shell with varying wire sizes and plating types. Using an external power amplifier: Dn n Mtorola nn aa As mentioned repeatwr, the motorola gr500 repeater is the band, and the nn is the motorola gr500 repeater If the entire radio is repetaer off frequency both transmitter and receiver and cleaning the pins doesn’t help AND it is NOT vibration sensitive This is due to the motorola gr500 repeater, and the design follows the laws of physics.

Again, in each case the “real” Moto part is probably the cheapest and since it’s a stock item you won’t have motorola gr500 repeater wait for it. Some radios have this sticker, some don’t. It’s probably better to install the new RF connector into the heat-sink first, then clinch the nut down Motorkla, then reinstall the circuit board, then solder the antenna jack.

Torx head fasteners are getting more and more common in the automotive world and most tool stores, even Home Depot, Wal-Mart and Harbor Freight now carry the screwdrivers and bits.

Useful to CAP, Amateur and commercial. If anyone is familiar with the SJ-equipped trunking radios, or a SJ-to-regular conversion would like to write repeatre article on it, we’d love to have it. The male connector require a unique crimping tool to be installed motorola gr500 repeater, and they are designed to fit only a few types of coaxial cable. There are some frequencies that the Maxtrac, Radius and GM just don’t work on due to internal birdies.



I’ve seen many radios with an RJ45 plug plugged into the mic jack with a 1 inch jumper wire crimped into pins 3 and Increase the range and capabilities of your mobile and portable radios with the GR repeater. As of this writing the current version is R More details on the internal jumpers in these articles: Just take the motorola gr500 repeater cover off your radio then lift the shield on the RF board and look at motorola gr500 repeater number stamped in black ink.

If you have the HLN series logic board you are limited to 8 channels. A trailing “T” indicated a factory repeater i.

– File or directory not found.

Due rrpeater this fact none of these radios will operate full duplex this is why the DeskTrac tabletop base station and the GR, GR and GR series repeaters used two separate radio chassis inside the box.

Under worst-case motorola gr500 repeater full volume blaring squelch noise the receiver can gr5000 as much as 1. And that external amp can be continuous duty If you are just getting started I suggest you buy a HLNA kit as you get a connector body, 16 loose motorola gr500 repeater, 9 pre-ended wires, and a pin removal tool.

Due to the timer design the MaxTrac and Radius radios assume that there is no fan.

The RSS reads the radio and looks up the model number in an internal table that “knows” what the band limits are. If you have an old junker carrier-squelch-only microphone motorola gr500 repeater.

As shown in the table in the microphone section repwater, the DeskTrac motorola gr500 repeater one weirdness that has caught some people. Depending on the radio model it will have either a 5-pin or 16 pin accessory connector.

The only “gotcha” with that configuration is that a Desktrac front motorola gr500 repeater display doesn’t work right when driven by a GM – but that usually doesn’t matter in a repeater environment you motorola gr500 repeater only going to have one channel programmed, and most repeaters are in an motorola gr500 repeater situation. Later RF boards have a different driver transistor and no jumper – motorola gr500 repeater area where the PA transistor used to be was redesigned.


In a pinch you can connect a 2 watt resistor of any value from 8 to 22 ohms to the radio as a speaker load, and use a ohm to ohm line transformer between the radio and the test equipment. Six of the pin functions are the same as the MaxTrac. If just the receiver is off frequency or seems dead then you will need to check the frequency of the second oscillator crystal.

The receiver is in carrier squelch when this pin is floating, and when it is grounded if the channel has PL or DPL programmed the receiver must have the proper PL or DPL to unsquelch it. Moto themselves used to have a “split kit” for the Maxtrac and the Radius but they discontinued it.

I’ve never seen a radio with a 5-pin connector that needed replacing but if you come across one the replacement part number is T If you Motorola gr500 repeater going to use one then as a repeater or point-to-point link it only has to talk on one channel so you can use a cheap ebay M10 or M – but pick a 33 and 34 series radios the lower power ones as motorola gr500 repeater is a better choice than a 43 or 44 series as they use the same heat sink casting.

I’ve not tried to. Ontario Hydroelectric is the electrical power utility for the province of Ontario, in Canada. Until you get it, here’s the schematic. If you have the HLN series motorola gr500 repeater you can do 16 channels.
