DISCLAIMER

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 AM-modulated 900km 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. Should the UVB-76 station- or transmission content owners feel violated in any way, please contact me at uvb76.repeater@gmail.com and we will work it out.

Note, that because of shortwave radio signal propagation specifics the station can be more or less reliably received from around 4pm to 6am GMT on summertime. It is almost 24h audible during the winter, with short "skip-zone" blank-out around 6pm GMT.

The USB feed is considered as main source of audio today, as the voice messages are much better audible there than on the AM stream. However, the buzzer sound from the AM stream is somewhat more pleasant to listen at, so both feeds are kept simultaneously.

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! :)
