Years of research in dusty library stacks and damp basements has revealed this:

The lower frequency cutoff on the dongles is usually around 60MHz or so.  However....lookee what I found:

And it even looks achievable by my (questionable) soldiering skills.

So now that you can pretty much have a complete computer for $35 or so, and add on a SDR for another $15....thoughts on how this might be fun?  Since you could have a $50 receiver right at your antenna, would it be easier to build arrays since you wouldn't have to worry about losses in the feed (just about running the ethernet cables between the boxes...)?

Earlier today I tried to log in with tapatalk for iOS and received an error that access from tapatalk was restricted or that the forum plugin wasn't functioning.  Has anyone else had a problem with tapatalk lately?

The quicksilver SDR QS1R looks very nice, but I can't justify the cost right now.  A sub $50 dongle would be great to play with, but I don't think they'll perform on the SW bands I want.

North American Shortwave Pirate / SSTV or FAX 6925u 0146Z

Sounds like SSTV(?) or FAX.  Fades in and out.

If it _is_ SSTV, is there anyway to tell what mode?

Are you experiencing a lot of noise on 6925?
