1. SPECIFICATIONS Function………………….The 6m Discovery is a desk top linear RF amplifier with a nominal output of 1000W covering the range 50 – 54MHz for amateur radio use. Type of emission…………………………………………………SSB/FM/CW/RTTY Dimensions………………………………….……14in wide x 9.75in high x 17in deep 360mm x 250mm x 430mm Weight……………………………………………………………………………..25kg Output power…………………………………...…………………….1000W CW/SSB Gain……………………………………………...………………………12dB nominal... - Page 4 2. INTRODUCTION The 6m Discovery is a high quality linear amplifier which is designed around a GS 31 medium mu triode in grounded grid configuration. The amplifier uses a Pi – L network in the output circuit and a tuned input circuit. The amplifier is forced air cooled to give you the ability to operate at full output power for as long as you wish.

Page 8: Operation
5. OPERATION SET-UP Connect all the cables as previously described in the manual, then double-check. When you are satisfied that everything is correct and the STBY/TX switch is on STBY, switch the amplifier on. There is a slight delay while the soft-start operates, then the POWER and WAIT lights should be on. - Page 9 STBY/TX switch to STBY then back to TX. The LED should now have gone out and the amplifier is able to be keyed once more. Tune the amplifier correctly to achieve maximum output with minimum grid current.
