[MAMS] condx this AM

[Dave Sublette]

I have the Ensemble II RX, good for 1-40 mhz per my testing.  I agree. 
Eliminating one variable would help.  However, you may have to add an 
LNA somewhere in the chain to get good sensitivity....  In my case I had 
to put a 144 LNA between the microwave IF out and the 144-INT input in 
order to get it to perform as well as the K2/DEMI 144 b oard combo.  I'm 
sure that shoots the dynamic range of the system, but where you are, it 
won't matter.

I can see 96khz of B/W with a 96 khz sample rate on my sound card. 
That's an other thing....all sound cards are not equal.  Getting a good 
sound system is the key to getting good performance out of the Ensemble 
II. (or any SDR for that matter).  Evidently my sound card is "good 
enough" judging by my results.

Good luck.

Dave
