I am interested in new RF technologies with the goal to implement them in my RF projects. On this site you will find some of my current microwave projects. Two of these were presented to 50MHz and Up Northern California Group.

   I like to operate weak signal communications. Here you can listen to the files recorded on July, 13th 2003 during the tropo ducting between California CM87 and Hawaii BK29 on 2m  70 cm   23cm at the distance of 3789 km. I operated from Northern California with 23 cm synthesized transverter and 35 el. M2 Yagi, located at 1.7 m above the ground.

   LNA project was published in DUBUS magazine Vol. 32 in Nr. 3/2003 pages 9 to 16. New article 'High Performance Low Phase Noise PLL Microwave Source' is published in DUBUS magazine Vol. 35 in Nr. 1/2006. For more about this project click here.

   Below are some of the pictures from Jamesburg Big Dish EME operation. The first EME contacts were made on Feb 29^th 2007 at 1296 MHz. The Cassegrain 29.7 meter's diameter with the gain of 52dBi at 1296 MHz. I used HB 100W SSPA, HB transverter, HB preamplifier and FT817 with 500 Hz filter. The feed is modified W2IMU feed with circular polarisation. On the video the dish is pointing to the Moon and you can hear voice SSB echoes.
