Just before Christmas 2003 some first DATV units were completed and tested by hams 
and students lead by Uwe, DJ8DW, at the Wuppertal University and then delivered to 
orderers according to the listing. Hans, PA0HKS, performed some contacts with one 
of the new units in the Netherlands, to Germany and to Belgium, using a prototype 
up-converter 70/23 cm from Wuppertal and a 30 Watt PA with very linear 2C39 valves.

Earlier the university club station DL0DTV had done an OFDM test (DVB-T) on 23 cm 
with 4 Watt into a 10 dB omni slot antenna. Receiving unit was a DVB-T Set-Top Box 
with down converter and loop dipole, pictures were good in spite of strong 
reflections between the mountains. An additional DATV TX board for OFDM modulation 
is in preparation, especially advisable for DATV repeater outputs above 1 GHz with 
multiple reflections in the surrounding area.
