Operated portable from DN65, DN66, DN67, DN68, DN75, DN77, DN93, DN92 in 2008 on 50 MHz

50 MHz CM79 grid expedition June 16-24, 2010

QSL 100% direct or via bureau. Please enclose SASE unless you're a VHF DX station.  I also QSL via LOTW and eqsl.cc

Active on 1.8-432 MHz + 10 GHz.  Other microwave bands "soon".

I occasionally operate bicycle mobile CW

A capacitive-sense paddle is used.  The touch-electrodes for dit and dah are attached to the left shifter on the bottom.  I key with my thumb and index finger and my other three fingers grip the handlebar and shifter.  A bicycle computer for speed and distance rounds out the dashboard.

The body of the rig is attached to an old pannier.  The battery slides into a pocket in the rear.  The antenna is mounted on the end of the rack.

No Fusion power yet!  An industrial-strength Li-Ion battery is used, 14.8V 21 Ah.  I used two of these for my CM79 grid-expedition.  Here's the battery on top of the seat for scale.  Fully charged the battery voltage is 16.4V so a bridge rectifier wired as two series-parallel diodes and attached to a small heat sink is used to drop the voltage to what the Icom IC-706 will take.  The diodes can be bypassed when the battery voltage gets low enough.  This battery provides hours of intermittent use at the full 100 Watts out.  This battery will burn very vigorously if punctured so it cannot be shipped by air per FAA rules.  1/2 of an old headphone is attached to the helmet (visible on the rear rack).
