BATC Forum

Last Sunday during the BATC SummerFun ATV Contest, Rob MØDTS and Terry G1LPS again teamed-up, and also Noel G8GTZ and Arthur G4CPE teamed-up to add some new DX records on the UK temporary digital band allocation at 146.5 MHz. Both of these two new records used narrow-band DVB-S modulation set to 333 KSymbols/sec to produce a bandwidth of about 0.5 MHz in the 2 M allocation. Both of these two new records also used H.264 video encoding to increase/improve the video frame-rate displayed at the receiving end. Below are the current Known DATV DX Records that I have gathered:



Please let me know if you learn of any longer DATV QSOs.

Daniel EI9FHB has suggested that the HamTV DATV one-way transmissions from onboard the International Space Station (ISS) on the 2.4 GHz ham band is a worthy addition to the Known DATV DX Records table (below). I have added the first day of HamTV-live-video-transmissions that occurred on 2014-03-08 and were received by the Matera tracking station (IØKPT) and the Casale Monferrato tracking station (IK1SLD) in Italy as being typical when ISS is near Horizon.



One of the goals of one-way-video using HamTV onboard the ISS is to communicate with schools around the world. If you have not watched before, a historic video preserved from those first ISS DATV transmissions can be found at

Again, please let me know if you learn of any longer DATV QSOs.
