Thank you for visiting the N2HJD/R web site
Bob Shewell, N2HJD Trustee

N2HJD/R got named the megaplex because of it's size and complexity.
The repeater system consists of 13 Amateur repeaters cross linked on 6 different Amateur bands. There are 11 sites all radio linked in two counties around the Rochester,NY area.
The system also contains a translator, remote receiver, 2-meter remote base, an internet interface, and a  DIGITAL VOICE RECORDER
The N2HJD repeater system is all home brew with 17 CONTROLLERS, 26 receivers, and 21 transmitters, and has evolved from May of 1988 to it's current state.
There is also full telemetry, with normal and reverse autopatch along with a link to NOAA weather. This system is also linked to IRLP. It's node number is 7250. Most sites have emergency power because the repeater system is an ARES affiliate.
This network is privately owned and is affiliated with the:

Rochester Radio Repeater Association.RRRA.
