Topband: Web SDR's and 'Cheating'

[ct1ilt at sapo.pt]

Why use SDRs when there are Beverages, Pennants, K9AY loops? does one  
feel satisfied knowing he/she worked a rare DX station using someone  
else's RX antennas? if you are really into DXing you will feel bad  
about it.

T32C heard 3 times now using single 170m long beverage towards W6  
(recording available for anyone who wants to know how it sounds in  
Northern CT).

If you hear it, you work it, simple as this.
