[R-390] Weak Signal Work with R-390A??

[Curt Nixon]

GM to the List:

I have been considering an approach to utilizing my R-390A for something 
other than the typical 80 and 40M AM, wideband Rx role.

The idea is to utilize the impressive dynamic range and sensitivity of 
the 390A with a low-noise receiving converter for 144MHz EME Duty.  The 
detection duties would be performed via a simple Softrock 455KHz IF SDR 
block. 

Is there anyone on the list doing anything in this regard?

Is there some reason this might not be a reasonable approach? 

I already have the antenna, TX and Amp in place for this but even using 
the SSB 2000 Mast preamp, my rx chain is inadequate.

Comments appreciated
