- working OH1CF ( KP00TD ) in Korppoo on 5.7 GHz troposcatter ( 79k ) from our club, OH2MOH in KP30CR

- the rig ( 106k ) has logged 5 contacts in it's 2 year lifespan: Texas, Sweden, France, Tampere Finland and now Korppoo !!!

- and a front view of the 6 cm ( 117k ) station pointing towards KP00TD

- checking the receiver with sun noise for 3.4 GHz ( 106k ) using a coffee can feed on the 120 cm dish

- close up view of the same 3.4 GHz setup ( 66k )

- overall view of the 3.4 GHz station during sun noise ( 106k ) and feed checking

- OH2JMS on the tower hoisting up the dish tripod ( 94k ) and 9 cm rig

- OH2JMS and OH1MRH guiding (106k ) the 120 cm dish up to the tower

- the 3.4 GHz ( 87k ) rig and 120 cm dish pointing towards OH3MCK in KP11WK for the Finnish record at 148 km

- my 3.4 GHz rig has now made two whole contacts since it's birth a year ago: Texas ( EME ) and Tampere, Finland !!!

- and here the same 120 cm dish is equipped for 5.7 GHz ( 97k ) for working OH3MCK

- the same 120 cm dish, now equipped with the 10 GHz ( 59k ) rig for working OH3MCK

- a general view (63k ) of our 1296 MHz and 10 GHz stations pointing towards ES0W during the Estonian Open Field Day

- the 1.3 GHz SSPA PSU current meter needle on its way up.... ( 65k )

- the 1.3 GHz SSPA CW current draw ( 65k ) from the 13.8 V power supply ( >>50 kW EIRP )

- incredibly, our rusted tin can feed ( 66k ) still has a >20 dB return loss at 1.3 GHz !

- a closer view of the 10 GHz station ( 63k ) pointing towards Saarenmaa, ES0

- OH2LVA pounding the key at the 1.3 GHz station ( 87k ) ( we had almost 40 QSO's during the contest )

- OH2LVA, the 1.3 GHz rig, PSU, SSPA, LNA and keyer, all running hot !!! ( 98k )

- another view ( 102k ) from behing the 10 GHz station pointing to Saarenmaa

- OH2JMS and OH2LVA digging for some more DX ( 106k ) from about 400 km away on 1296 MHz
