Re: [TenTec] My New Eagle vs. my old Drake

[Stuart Rohre <rohre@arlut.utexas.edu>]

If you look at the minimum detectable signal with the Eagle preamp ON, 
the dbm to Volts conversion looks to give you 33 NANO volts as the 
detectable signal.  This was derived from the Dbm to voltage table on 
the Mini Circuits web site.
The figure Kris quoted was for the Eagle preamp OFF.   Yes, 0.5 micro 
volt is plenty good on the lower bands where atmospheric noise may limit 
what you can receive.  The preamp gives you full flexibility to match 
the receiving conditions at any given time. (I suspect the Drake did not 
have a preamp, but it has been 45 years since I operated one).
