[Elecraft] Receiver Test Data Inquisition

[Bob McGraw K4TAX]

I looked at the Receiver Test Data from Sherwood Engineering. While it 
does show the FTsx101D (corrected) at the top of the list, there are 
other radios, models and brands, which show better numbers in other 
areas.   I'm not knocking any radio, I'm just saying;   "one best look 
at ALL the numbers before tooting ones horn".   Kudos to all the 
companies in the SDR market with their products.

Columns from left to right:

Noise Floor: --- K3S at -135 dBm

AGC Threshold uV: --- K3S at 1.5 uV

100kHz Blocking dB: --- K3S at 150 dB

Sensitivity uV: --- K3S at 0.20 uV

LO Noise dBc/Hz: --- Kenwood TS-890S at 155  dBC/Hz

Dynamic Range Wide Spaced dB: ---  Yaesu FTdx101D at 110 dB

                                                    and: ---  ICOM 7851 
at 110 dB

Dynamic Range Narrow Spaced dB: --- Yaesu FTdx101D at 110 dB


One might do well to look further into the performance detail and 
numbers.    Of course if one is into whistles and bells, the field is 
wide open an more up to the individual user and their specific needs.   
As Rob said in Huntsville a couple of years ago, "the best radio is one 
you enjoy using".
