80M MOPA running a 45 Hartley oscillator driving a 210 neutralized amplifier. Power output can be varied from a few watts up to about 15-16W depending on output coupling. The amplifier tank coil and output coil (3/16 in. soft copper tubing) rest on a pair of 1/2 in. acrylic rods, allowing the output coil coupling to be adjusted by sliding it closer to or further away from the amplifier tank coil.
All RFCs are homebrew, wound on 1/2 in. wood dowels, #30 enamelled wire. Approximately 250uH.
Note is pure, with no discernible chirp. However, the oscillator does drift a little and may warrant further experimentation.
