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.

USB for everyone!

Over the weekend, I was playing around with the USB interfacing for the SDR Mk1. And, to a great surprise, Monday, 1:30am I ended up with functional setup consisting of two serial ports and one 192kHz audio recording interface, all embedded inside one composite USB device living inside AT90USB1287!
What makes it really useful is, that it works under Windows7 without the need of any special driver - it manages with the internal ones.

It is unbelievable what Atmel with its AT90USB line and Dean Camera with his LUFA framework have done to USB world! Creating a working HD audio and two serial ports by totally USB-illiterate person with one weekend is a living proof that Dean is a genius and Atmel knows how to make chips!

Thank you, one step closer to a working SDR :)
