I am a licensed amateur radio operator since 1963. Magic of shortwaves and electronics intrigued me since childhood and I've got my first callsign being teenager in the high school. We've been very lucky to get a good teacher - ham radio operator (UD6BU), who organized our club station there, and it was the place where I've made my first steps in ham radio. The first transmitter I've built was all tubes 10m AM with 807 tube as a final housed in the box and used parts from the old WWII V-100-B radio, and as a receiver I used old military surplus Soviet made KV-M with additional 3 tubes frequency converter for 28 mhz (the KVM didn't cover 28 mhz band). It's hard to imagine now how to work in the air using so many controls to tune all these pieces of equipment without conveniences of modern transceivers but it was a lot of fun as I remember. Then... I got married, moved, started to build my career and for some number of years went off the air. I was working as an engineer, then completed my research work and received a Ph.D. degree in 1977. After that for a number of years I worked in the mining industry designing and developing transducers and control systems for coal mining machines.
That time I remember I was very enthusiastic about building and fine tuning audio systems, amplifiers, turntables, tape recorders. My ham radio past was hiding somewhere and waited for new beginning. And one day it happened.
During one scientific experiment in our laboratory, I encountered unwanted interference and recognized that it comes from some ham radio station. I decided to search around and found a club station nearby, knocked on the door and ... got hooked immediately. Soon I've got my new license and since then never parted with ham radio. Over the years I've build a number of different pieces of ham radio equipment. The first transceiver I've built was famous UW3DI design, the most popular design in former USSR, which was reproduced thousands of times by different hams. Then my ego pushed me to another challenge - I decided to design and build transceiver with single frequency conversion utilizing a home brewed crystal filters for the IF tract. I used some ideas and circuits from multiple sources, and the result was a new unit with two 9mhz 8-pole chrystal filters separately for receiver and transmitter, the final stage was using Russian made tube GU-19 since I didn't have enough resources and experience to make a solid state final. The output power was hardly 40-45 watts, but it was lots of fun to make contacts. I left it to my friend before leaving country. For some reason it didn't work well in his house. He told me that it produced strange AC-like hum (maybe some power supply design problems? It worked well for me, would be interesting to troubleshoot and fix, but this unit is out of my reach. What a pity.)
Testing in the field
Unfortunately, I was not able to bring anything with me when we went through very complicated emigration process existed then in the Soviet Union. We left almost everything behind and came to the United States early cold spring 1990 after 5 months of living in Austria and Italy since we had to wait for visas. It was difficult time for everyone of our family - new country, new language, no money, no job... But persistence and hard work helped us to overcome many problems. In 1995 we've bought our small house - an "American dream" (my Inverted Vee is visible behind the house).
Since 1994 I worked for the hospital first as a senior engineer and then as a supervisor in Biomedical Engineering Department. My responsibilities included variety of functions such as clinical engineering, evaluation and testing of the medical instruments, interacting with another departments and equipment manufacturers and managing work flow. I retired in September, 2016 and I'm enjoying life every day since!
|In my office|
The first call sign (AA2HO) in the United States I received in 1991, when I completed all tests (including CW for Extra) in one shot from Novice to Extra classes. Then in 1996 I applied for vanity callsign N2HO and use it since.

For logging I use fine and free UR5EQF software.Unfortunately the author, Vladimir (UR5EQF), passed away a few years ago and further development of this software stopped.
