-The RTL-SDR is based on two chips -- the versatile [http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PFid=35&Level=4&Conn=3&ProdID=257 RTL2832U chip] and the [https://rtl-sdr.com/wp-content/uploads/2013/04/R820T_datasheet-Non_R-20111130_unlocked.pdf R820T tuner]. The RTL-SDR is currently the cheapest, most common, and most performing solution available in terms of general sensitivity having a frequency range of 24 – 1766 MHz.  A metal enclosure with SMA connector is preferred, along with a stable TCXO (low ppm).  HF coverage is optional.

 You should now schedule several observations to fine tune the <code>SATNOGS_RF_GAIN</code> value to get the best S/N performance for your station.   Some have reported needing zero RF gain, others have reported low RF gain required (between 5 and 10 db), and others have said they see little benefit even with very high gain. Each station will be different.
-====E4000 Tuner Gain Settings====
+===E4000 Tuner Gain Settings===
 The RTLSDR Driver exposes six (!) IF gain settings (IF1 through IF6) for the E4000 tuner, along with a TUNER gain setting, which is actually a combined LNA and Mixer gain control. Details on the gain stages are available in page 28 of the E4000 data-sheet here: https://www.nooelec.com/files/e4000datasheet.pdf
-When you follow the '[[Omnidirectional Station How To#Setting the gain|Setting the Gain]]' guide, all gain sliders (IF1 through IF6, and TUNER) should be presented in SoapySDR, allowing the user to adjust them to optimise for best performance. Once the correct values have been determined, you will need to define these specifically in satnogs-setup as follows:

Once the correct values have been determined, you will need to define these specifically in satnogs-setup as follows:
 *<code>SATNOGS_GAIN_MODE</code>=<code>"Settings Field"</code>
 *<code>SATNOGS_OTHER_SETTINGS</code>=<code>"IF1=6,IF2=3,IF2=2,IF3=0,IF4=0,IF5=2,IF6=3,TUNER=30"</code>

 ====R820T Gain Settings====
-Unfortunately librtlsdr only exposes a single gain control for the R820T/T2 tuners, even though multiple gain adjustments are available. Use the standard SATNOGS_RF_GAIN option, with a gain between 0 and 42 (dB), as optimised for your station via the '[[Omnidirectional Station How To#Setting the gain|Setting the Gain]]' guide.
