Coming along nicely - 60 watts fully modulated on 160 and 80 mtrs - just waiting for a coil former to test 60 mtrs.

Front panel all drilled and fits - just needs powder coating.

In the fullness of time I may add a digital frequency read out in the space directly above the VFO knob, but for now I'm keeping it 'vintage'.

Meters are from China £3.50 each, left to right modulator anode currents, PA grid current (10mA FSD), PA screen current (30mA FSD) and PA anode current (300mA FSD)

Still lots to do both mechanically and electrically but getting there.

Many thanks to everyone for their help and guidance.

Some pictures of the front, top RF internals and modulator.

Regards Tim
