[amsat-bb] receiving APT on 137 MHz

I have several ways to do it.

I have one of the old Hamtronix R139 crystal controlled receivers I 
built from a "kit".

It wasn't what I'd really call a kit, more like a box of parts with some 
instructions. It works fine once you get it operating.

I also have an old Radio Shack scanner I "converted" by pulling out the 
IF filter and replacing it with a fixed capacitor. It also works "OK", 
and considering I have about $5 in it, it's winner in the 
"Bang-for-the-buck" category.

And lastly, I have several of the USB "dongles", including both versions 
of the FunCube dongle.

They all work fine using an M2 2 Meter eggbeater with an SSB Electronic 
2 Meter preamp mounted at 20'.

Yes, I know I'm using the antenna and preamp way "out of band", but it 
doesn't seem to hurt. I get solid copy from when the APT birds are above 
10*, and that's plenty good for me.
