PCB with components for a single valve 3.579mhz Xtal controlled CW transmitter. Original design by the late Ron ZL1TW as described by the late Gary ZL1AN on his website https://www.qsl.net/zl1an/ with a correction. I've had up to 60 watts out of it using a 6L6 and 400v HT. You have to supply the power supply ( I used an old broadcast band valve radio transformer, rectifier & caps from Jaycar), an ATU (variable caps from old broadcast band radios), an antenna, key and operator and of course a valve and a box. The valve can be a 6V6, 6L6 or EL34 all plug in equivalents. Also available for 7.023 mhz. Board size is w 90mm, h 30mm, d 55mm, designed by Bob ZL4CE manufactured by PCBWAY Only available to licensed radio hams, please supply callsign when ordering. Free freight tracked by NZ Couriers, please add $4.55 for rural delivery.
