GB3HR, The Harrow 433 MHz (70 cms) FM Repeater

A new UHF Base Station has recently been installed and is running 9 Watts erp from our site near Harrow Weald. The new transceiver consists of a Kenwood TKR 851 running 12 Watts RF output on 433.350 MHz and receiving on 434.950 MHz. The station will relay FM transmissions when a continuous sub-audible tone (CTCSS) of 82.5 Hz is sent. The station identifies as GB3HR D in Morse Code, the D denoting the sub-audible code 82.5 Hz. The station has also had a new 6dbD gain collinear antenna installed and this has greatly improved coverage throughout Watford, Harrow and surrounding areas.
