This device is cute and looks like a really neat thing to play with.
With a USB A-B cable extension, this could find widespread usage for
Microwave and satellite types. I only want to sound a small note of
caution before folks jump and buy.
Signals that would cover up a signal on S band from either the P3E S
band system or even the (proposed louder) Eagle S band system will be
beneath this device's noise floor. An 802.11, Blue Tooth, microwave
oven, cordless phone signal, etc. could be tens of dB louder than the
signals of interest in the proposed P3E or Eagle transponder downlinks
and this device would have no detectable response to them.
What that note of caution, for $99, it will be a really neat thing to
play with and it will be able to find the largest interlopers on your S
band passband for P3E and Eagle or AO-51.
