Ham Radio Television

A tour and demo of my ham radio television station (Amateur Radio Fast Scan TV.)

The transmitter is an HV-320 produced by HiDes. It puts out about 1 watt of power. The receiver is an HV-122 also made by HiDes. The HiDes transmitter and receiver send and receive using DVB-T The power amplifier is a 23cm, 30/15/4.5 Watt, 49 dB Amplifier Model 23-11A by KH6HTV.COM.

While testing at home I'm transmitting and receiving on 1.243Ghz, but the HV-320 and HV-122 can transmit and receive on any Amateur Radio band between 100Mhz and 2.5Ghz. There is additional information about Amateur Radio Television at kh6htv.com/application-notes.

Nice setup for DATV!
What are the equipements used and type of modulation and how many W and what band(UHF)/frequency you used?

Thanks for your question. I've updated my original post to include that information.
