ATS 909 vs AR3030

The Sangean ATS 909 is not a bad receiver, actually, I believe for the priece, it is a very good receiver. But, how good is it?
To find out, I did the following test:
  1. run the ATS 909 with the Octaplumb
  2. run the AR3030 with the Octaplumb
At the same frequency, measuring SNR (using WSPR) of stations receivable via ground wave.
On 600m, that was the result:


2010-03-03 21:26  G4JNT  0.503884  -11
IO90iv 
PA1GSJ  406
 2010-03-03 21:22  PA3EGO  0.503927  +10
JO22mb 
PA1GSJ  52 
 2010-03-03 21:14  G4JNT  0.503881  -22
IO90iv 
PA1GSJ  406
 2010-03-03 21:14  PA3EGO  0.503923  -1
JO22mb 
PA1GSJ  52


It seems, the AR3030 has got a 11dB advantage in SNR over the ATS 909. In other words, the relatively inexpensive ATS 909 is just 11dB short (in SNR) to one of the world's finest receivers.
