I am engaged in the
radio for a quite long time. At the beginning of 70's I have got
russian kit with parts for simple radios. After long and hard work I
managed to receive Polish main broadcasting station „Warszawa
I”. I started to collect radios , parts and make various
circuits. Probably in 1974, in scouts camp, our scoutmaster, Slawek
(SP5ICS) proposed the M Apart working on the air
I assembled direct-conversion receivers which fascinated me due to
it's simplicity. Circuits based on RA3AAE harmonic mixer was the
best.
The first period of my
ham activity was broken by marshall law period in 1981. In 1984 I
come back to my club, reestablished home equipment and was active
locally on 2m for some time. For next twenty years I
was entirely engaged in my work and family. All my radios and parts
were packed. In 2004 probably, I
discovered the variety of ham information on the Internet. I was
also suprised by popularity of QRP. I took out the old radio
parts and assembled simple homodyne receiver on 20m. Next year, I
found the offer for FT-7 transceiver on www. It looked so nice, that
the decision was very quick. This way I am QRV again, QRP only, of
course! I am trying also to be active in QRP community. The internet
helps with it remarkably, so I keep my own site and try to share
with my experience and joy. vy 73, Marcin, SP5JNW. My „shack”

code learning. He had a key and Morse generator. I listened, tried
keying and went to club station SP5ZHM to see real HF radio, just
after the holiday. They had wonderful, old Russian RBM-1 with PA and
RFT-188 communications receiver. I started to practice on club
station and applied for my own license in a short time. I have got
listeners licence first (SP-1683) and next my so longed-for callsign
- SP5JNW. My club lended me old, Russian tank transceiver –
10RT. I hanged 20m of wire and tried to tune the radio. The receiver
was OK, but I could not manage with the transmitter. So, I assembled
four-transistor, 3W input transmitter. The first day was lucky: I
had 2 QSO, with Slovak and Ukrainian stations. This way I become QRP
fan. Within first two years I collected many European countries on
40 and 80 meters. My transmitter was very primitive. I changed the
band by tuning the output LC tank to 2-nd harmonic! This way I did
unique QSO. After my CQ on 40m I heard very weak reply from local
station. Why weak? We worked on different bands. He heared my
subharmonic on 80m and I heared his 2-nd harmonic on 80m!
