Hi Greg, I believe that your Pinnacle PC Card is not for DVB-S (Satellite networks) but for DVB-T (terrestrial networks). Please check on the web or give me the model of your card, so that I will check it. Emanuele I0ELE

Hi Emanuele,
Right. But what is that in terms of what normally gets described? For example, I have a Digital TV card for my computer (Pinnacle PCTV HD). It says it does "ATSC digital TV (HDTV up to 1080i, and SDTV)" and "Clear QAM (unencrypted digital cable)".
Am I even close?

HAMTV stream will be transmitted at 1.3 MSym/s or at 2.0 MSym/s. Technical specs of the set-top box indicate the range of the decoded stream. Generally this range is from 2 to 45 MSym/s, therefore if you need to buy it, you should select one that can guarantee a range from 1 to 45 MSym/s.

For the digital TV challenged, what means "Any DVB-S Decoder which can decode a 1.3 MSym/s TV signal"? How would I know if I have such a thing, or what I would need to get if I don't.

Certainly! You can find the nominal link budget on http://www.amsat.it/HAMTV_Link-budget-IARU.pdf and all the relevant information http://www.amsat.it/Amsat-Italia_HamTV_brochure.pdf. However
- Recommended Antenna gain > 25 dB
- RHCP
- Low noise down converter i.e. Kuhne LNC 25 or LNC 25 TM NF 0.7 dB
- Any DVB-S Decoder which can decode a 1.3 MSym/s TV signal
