Here is a table of the current equipment
and also some notes on equipment to come. Most popular bands for roving
are 1.3 to 10 GHz, which I activate several times a year. Need a sked ?

My 3.4 GHz, 5.7 GHz and 10 GHz equipment was used for Finnish Firsts on EME (Earth-Moon-Earth) from OH2AXH !
The G3JVL (70k) 10 GHz transverter is one of a total of three I have built and this particular one was used for the very first SSB/CW contacts made in Finland with my friend OH2DV.
The 24 GHz narrowband equipment is an ongoing project. OH2JMS and myself are building our own versions of DB6NT and CT1DMK designs.
ATV equipment is fast scan TV, PAL-B/G,
AMATV or FMATV (64k) with 8 MHz deviation. Best
QRB on 1.3 GHz FMATV is 26 km non-line of sight.
Also working with MPEG-2/QPSK Digital ATV equipment on 1.3 GHz to start with.
Looking for 47
GHz stations with narrowband equipment.
Desperately need a buddy for working on 76 GHz, darn quiet on this band...
Laser experiments are now cooling off for the summer (too bright outside for the receivers !).
Used this equipment for SHF contesting at OH2Z:
And also used for a couple of records from OH2Z
