Hi Andy 
In a word..NO...the signal even without any actual video content is still around 2MHz wide.
If you have simple rtl type dongle you might be able to see the signal tho

Subject: [amsat-bb] Using AO-40 in Rx for Ham TV?

I was just wondering if the AO-40 LNBs connected to a Funcube dongle (and a bias tee for power) would recieve the carrier (is there one on DATV) from the ham TV test transmisisons? 

If so, that should be a project that could show AOS/LOS , power levels etc, even if it's a black screen being sent: after all, it's RF.

maybe this has been thought about before? But I could use my converted blue lnb...
