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.

The (not so successful) Antenna Upgrade

It was a little more than a week ago when listening station received its new resonant Magnetic Loop Antenna. So far so good, however, the coupling toroid (see the yet-to-be-published design of the antenna :) ) was of low frequency type (Russian M1000HM to be exact) starting to cut off at about 1MHz accordint to datasheet. The replacement toroid, T80-2 runs well above 5MHz and looks to serve as proper replacement. 
The result, however, was disappointing to say the least. Todays antenna tests with various configurations ruined several hours of broadcast, but the signal with new toroid remained noisy. It was also almost impossible to tune the antenna (or tuning to have any effect), so the old toroid is back and so is the signal. Back to the drawingboard.

    - Gào, hú..

    Ở giữa không trung, từng thanh âm gầm gừ vang lên, ngay lập tức Nhạc Thành nhìn thấy, Yêu Cơ, Khiếu Thiên Hổ, Tử Điện Mãng, Tứ Sí Ma Ưng khí tức trở nên tăng vọt, thân hình cũng mở rộng.

    Với thân hình tăng vọt, khí tức trên người của bốn con ma thú cũng cấp tốc tăng lên, một lát sau cũng đã có ít nhất thực lực nhất tinh Đấu Thánh.

    Nhìn bốn con ma thú biến hóa, Nhạc Thành liền nở ra một nụ cười.

    - Ầm ầm ầm.

    Bốn luồng thân thể lập tức thu hồi bản thể ở trên không trung, khôi phục nhân hình quay lại bên cạnh Nhạc Thành.
