UVB-76 Live Stream Blog

DISCLAIMER

IT IS TIME TO TAKE SIDES
During almost 12 years the repeater has been up, I have been keeping it apolitical. But Putin has gone batshit and UVB-76 radio station is a weapon. So, while I keep translating it, you are welcome to also watch the Ukrainian news channel '34 Kanal' to see, what kind of events this signal is actually participating at today.
Slava Ukraini!

DISCLAIMER: I have no association with UVB-76 station, neither do I have any clue what is the content I am relaying. I can only assure, that the signal is received on 4.625MHz about 300km NW from supposed origin and retransmitted unaltered. In no way can I guarantee this service, nor be considered responsible of any content re-transmitted. The only purpose for this relay to exist is because lot of people who do not have equipment or are located too far from station seem to be interested about listening to it. Note, that because of shortwave radio signal propagation specifics the station is not always audible

SDR MK1 Shortwave Radio Shematic and Layout Update

The SDR MK1 project page has been updated with new schematic (v1.02) and has now also a layout with some explanations about what and how.

The PCB-s went already to production and I expect the boards and components arrive some time next week, so the moment of truth is quite near :) (Although the software will likely take several more weeks t polish).

As a sidenote, I just realized that having the dual channel shortwave software radio may be a nice thing, but having another channel tuned on utility frequency range would make it even nicer tool locally. With appropriate bandpass filter, we can nicely tune from 144MHz amateur band up to the 174MHz TV ch.7 with our 30MHz spectrum width, so it covers most of the open utility channels.

Guess I have to start designing a filter boad! :)
