UHF Digital Repeater Construction
Yaesu offered our club a Yaesu DR-1X, VHF or UHF, with a FM and Digital repeater at a low price.
AMARC purchased one of these repeaters. The repeater has to operate for a year, to keep the repeater.
The club was unable to get a new frequency from Missouri Repeater Council.
So I setup the new repeater on the High Ridge UHF Remote base frequencies on 444.850/449.850 with a new PL Tone at 141.3. This way the digital repeater and the remote base can share the frequencies.
Installation of the Yaesu DR-1X Repeater
Set-up the DR-1X repeater was easy. They have a programmer on the front of the repeater. I set the frequencies, PL tone, the ID call, and set it to auto.
That way the repeater can receive FM and transmit FM, and receive digital, and transmit digital, but not at the same time.
It is mounted in the 6 foot GE Cabinet with the 2 meter cavities, and 6 meter AM receiver.
The pre-amp has 4 ports, three were in use for the 449.550, 449.750 and the 449.850 repeaters. A cable was made from the pre-amp to the new digital repeater receiver.
An old GMRS transmitter antenna was used for transmit.
