[amsat-bb] Re: Cheap S-band Analyzer

[Bob McGwier]

Tony:

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.
