Hello, Was wondering if anyone has had any experience with this particular model of Repeater ? I am having trouble with the fan control section which i believe is actuated by the main repeater controller board that also controls the Audio path between the RX and TX radios. I have contacted Panther Electronics but have not received any reply so i assume they do not provide any support for obsolete products. The contoller board contains 2 555 timer chips along with a selection of resistors, 2 pots and several transistors which i think might control the fan timer circuit. Bypassing this section altogether and wiring directly to the fan relay mounted on the fan itself brings it into life but i would prefer to have the original circuit working if possible. If anyone has any info on this board and how it is supposed to operate in regards the fan circuit, and also if it alters the Rx audio signal path between the two transceivers i would be most appreciative for any help. A circuit schematic would be really handy or any other info.
All replies gratefully received.
