[Lowfer] Argo performance with low tone frequency?

[N1BUG]

Help! Does anyone know if there is any reduction in performance or 
detection sensitivity using Argo for QRSS / DFCW with the signal at 
a low tone, say around 170 Hz?

The last two nights I have been listening for DF2JP on DFCW but I 
was concerned about this. So I set my receiver at 135.000 to get 
1173 Hz tone in Argo. This means I could not monitor WSPR2 at the 
same time. Now I am wondering if it is just as good to leave the 
receiver at 136.000 and run Argo in parallel with WSJT-X for WSPR.

I suppose I lack a real understanding of how the detection works and 
thus don't know if tone frequency has any affect at all on 
sensitivity. I use a SDR so it should be no problem to adjust the 
filter to pass 173 Hz to the decoder. Of course I also have to check 
whether the wider bandwidth upsets WSJT-X...
