Rod,
The GR300 is a completely different animal. The GR300 comprises two GM300
mobile radios, a RICK, and a power supply in a desktop cabinet. The GR500
comprises an R1225 full-duplex radio (which has a built-in controller) and a
power supply in a wall-mounted cabinet.

Do you know what it is using for a radio or radios? GM300s? R1225

It should make a pretty good repeater except either one of those
combinations isn't the best for long winded QSOs. Make sure the fan is
in good working order and the air intact and exhaust
No matter the cost, you can probably find a Micor or MASTR II for the
same or less price, and it will be a much higher quality repeater.

Randy,
Yor are correct. The GR300 and GR500 came out about the same time, long
before the R1225 transceiver. We have many of the GR500's configured with
two M-120 radios. 73,

I use the weekly area 2m net to help others understand what a repeater
is, the proper way to announce your call, unkey, then continue when
checking in on a net, or in Simplex operations.
It is integrated into the script, and there is always time set aside for
questions, additions or corrections
Can anyone help me with the diode matrix pattern for programming call
signs in the clegg 376 vhf repeater? This is a clegg 220 MHz
repeater. All help would be appreciated. Also looking for a
schematic for same repeater.

Eric and all,
The GR500 is only a wall mounted housing, power supply, and fan. The RF
package inside the housing can be a pair of Maxtracs, a pair of GM300's, a
pair of CDM750's (in which case the box is called a CDR750), or it could be
a R1225(very rare). The GR300 is a desktop housing and a
I would say that the price is a bit high for what are described as 2 mobiles
with no duplexer and no mention of a controller.
I was looking at the DRx35 series radios as candidates for just such a setup
for temporary crossband repeaters. They look interesting.

Thanks for the confirmation Kevin. I thought the information about the
GR500 being a completely different animal than the GR300 was incorrect.
The GR500 cooling screamed at full speed regardless of heat. I used to
disconnect the fan so I could hear myself think while working on the

as a VE I will say if they can pass their element 1 thru 4 they have a

Freddy,
It's less than that. The B exciter put out typically around 80 to 150
milliwatts. If I remember there is not an amp between the exciter and
amplifier. It's been a while though, I can look at the book and see.

Chances are you don't have a complete clegg repeater, but
a repeater made from mostly clegg rf parts and the id unit
is one of the diode matrix units made by Hamtronics or
VHF
That is interesting! Obviously, there is more than one model of the GR500.
The Service Manual I have for the GR400 and GR500 repeaters, 6880905Z54-O,

transceiver. I have an RKR1225, which is the rackmount version of the

It comes with the stock controller, tuned to our coordinated pair and

The TLE1713 PA takes 1.4 watts input to make 92 watts output, before the
circulator, and about 75 watts after the circulator. The control wire takes
voltage, not a ground to make the amp work. Typically, about 6 volts for
full P.O.

The topic of batteries has come up several times lately. I know that I
have questions like a few others do. What I would like to ask is if
you have a repeater on solar and or wind power, would you let the
rest of us know what you are using to charge the batteries, what
type of charge
Sounds like a UHF repeater as the Motorola stock duplixer for VHF will not
do 2 meter and not fit into the GR-500 setup.
