Bob ST2RS with the 2M and 6M EME station
IC-706MK2G, Acom 1000 PA (4CX800/GU74b)
Laptop for generating JT65 and CW, GPS for time sync
KenPro G5400 rotator, Astron switch mode PSU
Not in the picture ... Mirage B3016 remote 2M amplifiers.

Building the 2M moonbounce antennas.
The kitchen table is my favourite workshop!

Sometimes one must be a little imaginative
... broomstick and curtain rod booms
... and driven element insulators cut from a plastic box!

The 2M EME array ... 4 x 8 element yagis.
Homemade, extensively modfied W1JR antennas 11.3dBd gain each
Driven element is a 50ohm split dipole with ferrite choke "balun"
Slightly understacked to fit the small terrace. Total array gain 17dBd.

See how exciting building an EME array can be!

The phasing harness was made completely from 50 ohm coax.
8D-FB power divider and feedline, and 5D-FB phasing lines.

ST2RS at sunset with the local mosque in the background
There were 4 huge megaphone loudspeakers on the minaret
... they were 300M away and "60 over 9" during the call to prayer!

QRP? ... reduce your feedline loss and put the PA at the mast!

Adding another 3dB with a second Mirage B3016 brick.
The "Rat Ring" combiner was made from RG-6 70 ohm coax.
(I hope the apartment owner doesn't notice his TV cable is shorter!)

Next job, the 6M yagi ... I managed a contact with W7GJ via EME.

I also did some work! An 18mH lattice tower on the office roof with
2.4GHz wireless link, Hustler VHF base antenna and 2 ele wire quad
on 12MHz to contact our mobile field teams 1100km away in Darfur.
