Thank you.  I look forward to the data - particularly information 
on suitability for use with AM/ESSB in both transmit and receive. 

I can't see where either AM or ESSB are exactly suitable for weak 
signal operation which would imply some degree of AGC and make 
90 to 100 dB of image rejection sufficient for most AM/ESSB use.

I think the most recent price was $99 ... but it's appreciated.  

73,
