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 KV-M 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 PhD 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 the 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 a famous UW3DI design, probably the
most popular homemade transceiver 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
(probably some power supply design problems? It worked well for me, would be
interesting to troubleshoot and fix it, but this unit is forever out of my reach. What a
pity.)
Another project was a walkie-talkie radio (I've build a pair) for 10m band with long whip telescopic antenna from portable TV set, the photo mailed to me by another friend of mine whom I gave them as a present when we were leaving country in 1989.
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...
From the arrival in the USA I worked as a test engineer subsequently in two different companies but since 1994 I started my career working 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 2016 and I'm enjoying life every day since!
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. Later I applied for vanity callsign N2HO and use it since.73, George (N2HO)

Доброго дня Георгий.Синтересом прочитал вашу заметку.Радио я болею с пяти лет.Мой отец в прошлом тоже радио любитель.Как то он мотал транс.и оставил его на столе,мне стало интересно,я взял концы обмотки и вставил их в розетку.Дальше была больница и ожоги.Вот с той минуты я и заразился радио. Увлекаюсь радиоприёмом и постройкой детекторных приёмников.Последней моеё работой является приёмник на базе феровариометра от радиостанции Р-807 на средних берёт 5 станций "маяк","радио росия "и 2 украинских переодически прорывается какая то прибалтийская станция.это всё днём .Ночью слышны Анкара и Ватикан.Переодически слышно "Радио свобода".Антена 45 метров антенного канатика подвес на высоте 6 метров.Наушник капсуль ДМШ-4М. Чем нравится детектор,так это чистый без помех приём.Немного о себе .Меня зовут Юрий мне 40 лет живу в Бердянске это на берегу Азовского моря.Был приятно удевлён тем,что люди занимаются дальним приёмом на детекторы.С уважением 73.
Спасибо, Юрий! То, чем Вы увлекаетесь, очень интересно. Успехов Вам в конструировании и дальнем приеме!
Hi, my name is Pat (callsign ON4BP) and I was wondering if you
have a copy of the help file in English of the UR5EQF programm.
I just recently came across it and found this programm extremely nice to work with.
My email adress is: on4bp1@gmail.com
I would appreciate your efforts very much
