- A crystal controlled 10.45 GHz receiver to mount onto a 90 cm dish for Phase 3D ( photo, 55k )
- 10 GHz EME transverter used in 1995 for 10 GHz EME ( 116 k ) firsts from Finland
- Longest QSO on 10 GHz: 525 km from home, a Finnish record again !!!
- a photo of my most portable 60 cm dish ( 105k ) setup for 10 GHz
- a typical tropscatter path ( in this case a 92.2 km path regularly workable on 10 GHz ) Very definately NOT line of sight !!!
- studying different circular polarisation feeds for receiving the P3D X-band TX transmitter
- several FM-ATV television ( 64k ) transmitters and receivers ( photo of a portable rig ( 49k ) here )
- my current 10470 MHz portable FMATV transmitter uses a 60 cm dish (87k) with 33 dB gain
- rear view (80k) of the portable 10470 MHz 700 mW FMATV transmitter
- closeup view of the transmitter front panel (56k). The TX is based on a DRO oscillator for stability.
- three different variations of the G3JVL 10 GHz transverter ( photo of one here, 70k )
- two crystal controlled full duplex two-way FM radios for 10.2 GHz
- rain scatter experiments
- P-HEMT LNA's for EME and weak signal operation ( photo 1, 50k, & photo 2, 59k )
- 10.368 GHz mobile packet radio in 1994 !!!
- loads of prototyping for the AMSAT Phase 3D X-band transmitter delivered by AMSAT-OH
- klystron and TWT experiments
- several Gunn oscillators
- antennas for the 10 GHz amateur band
- professional work on several 12/14 GHz satellite earth stations, including MPEG-2
- BIG file: notes on modifying a Ku-band feed to X-band ( in Finnish )
- CW beacons for 10368 and 10451 MHz, 1 W out, not QRV yet
- interesting double reflection QSO's from home with OH2DV, armchair copy at both ends, QRB = 27 km
- contesting from KP20LE on 1.3, 2.3 ( 76k ), 3.4, 5.6 and 10 GHz ( 84k ) with OH2AXH ( in blue, OH2BSH at the key )
- Finlands first CW and SSB QSO's with OH2DV using G3JVL transverters back in 1982
- click here for photos of the OH2TI effort to accomplish the worlds first 10 GHz EME contact from way back in time !
- click here for some nostalgic photos from some 10 GHz tests in June 1984 !
