Biography

More then 100 DXCC were received with a receiver of an old and simple design, DCRX68 by W7ZOI on 40m band SSB.
I'm experimenting with another receiver prototypes and learning Morse code now.
RTL-SDR DIY KIT. It's a noisy BS, but still can receive something.
165 DXCC were received with a simple direct conversion receivers mostly on 40m and 20m band in SSB and CW modes.
I've installed FT8CN app for my Android phone. Experimenting with it now. It can receive FT8 even on a phone's mike, but I gonna build an interface cable for it.
I just tune my Motoroler to 14074 by ear then place my phone between headphones.
I can hold my phone in my hands and use it for internet browsing while FT8CN decoding messages.
In summer of 2023 I tried to get out of Russia for it persecutes Jehovah's Witnesses. I have a Bible study from them. I couldn't make it for my papers expired, lack of money, and poor health state. Russian betrayers have taken my Android phone so I've lost my Google account, my email, and many others of my internet accounts. I still remember my login and password for QRZCQ. :-)
I've returned to Lugansk. Hope to spend a winter here then I gonna go to Belarus.
My Motoroler had some issues, but it's performing fine again. :-)

Worked DXCCs:

Equipment

DCRX68 40m by W7ZOI.
End Fed Inv Vee 25m long + L-match. The antenna was designed in an empirical way. I've just hanged a peace of wire over an apricot tree then cut it in two peaces at a convenient to connect coax place. I've measured it's impedance with nanoVNA and calculated an L-networks for 40m and 20m bands with a Smith chart. These L-networks are switched with a simple relay.
RTL-SDR DIY KIT.
Magnetic loop of 3m circumference.
I've prototyped an si5351 based digital PLL for my DCRX68. Experimenting now. :-)
Simple solid state regen by US5MSQ 80m with ferrite antenna. Can read big guns up to 2000m distance.
Motoroler - 40m/20m MC3361/MC34119 based DCRX by my own design. It's powered with 3.7V LiIon battery. I've built an active CW filter for it (by Ten-Tec Century 22 design). It's based on lm324/tl084/mcp6004 and it performs great.
A simple homebrewed BF998&J310 based tunable preselector. It's powered with 3.7V LiIon battery. Just to keep my receiver's parasitic radiation off my antenna. It drains more power then Motoroler with headphones. :-)
