Cecil no doubt assumed that you want to see the spectrum near the  
point a receiver you have is tuned to.  The SoftRock thing, as I  
understand what he posted, does just that, though there is some  
confusion in my mind.  For lots more info Google "SoftRock SDR Kit".   
 From what I read, the SoftRock-40 was a 40 meter receiver, not meant  
for 455 kc, and is now sold out.  The SoftRock 5 follow-on project is  
now open for orders and appears to have options to accept signals in  
different ham bands.

However, you may have meant to examine signals at most any HF  
frequency (or even higher) and see what the signals in that vicinity  
are.  For example, the output of an SSB transmitter operating on 20  
meters.  For this use, the HP spectrum analyzers that folks have  
suggested will more suit the purpose.

I look forward to more advice on the list.
