RX Sensitivity Results
« on: December 08, 2013, 10:34:36 AM »
Here are some rfm69 sensitivity measurements for various rxbw settings.

 //----------------------------  bw meas results -----------------------------------------
 //  0.125%, dcc = 625 hz, rbw = 500khz,                          mds = -107dbm  with LNA sensboost      8/27/13                       
 //  4%,        dcc= 5 khz,    lpLabs default rbw=125khz,     mds = -109dbm  no LNA sensboost
 //  0.125%, dcc= 156 hz,  lpLabs updated, rbw=125khz,  mds = -113dbm  with LNA sensboost                             
 //  0.125%, dcc= 62.5 hz, rbw = 50khz,                            mds = -114dbm
 //  1%,        dcc = 250 hz, rbw = 25kHz,                            mds = -117dbm, LNA On  12/08/13
 //  1%,        dcc= 52 hz,    rbw =   5.2khz,                         mds = -122dbm
 //  2%,        dcc= 52 hz,    rbw =   2.6khz,                         mds = -123dbm, (best if fcut > 60hz), LNA on. checked agn 12/07       
 */

*mds is the weakest detectable signal

That's interesting info, thanks for sharing. What was/were the bitrates you tested at?
