Multiband exciter stages....

G6LBQ multiband exciter is almost finished.

Couple of things in the todo list including the LSB/USB crystals and crystal filter unit.
Certainty I have not tested any of the stages other than 1 & 2. I just measured the current consumption of both stages.  23-25 mA deflected in my multimeter.

MK2 exciter uses LM380 as the audio amplifier.LM380 (8 pin) version is not readily available in the market, I need to look for a good source.
