I purchaser the E4000 receiver, L-Band Amp, Patch Antenna, and RavPower pack from
Amazon. It all appeared to work Ok. The SNR hovered around 2.0 db and did receive several
files but everything deteriorated after a few says.
I ordered another E4000 and L-band Amplifier to swap out. I also ordered a RTL-SDR Dongle
to try out. I ran into the same problem with the new components. Low signal with no files
received. Only seeing a signal lock and one bar now and then.
The RTL-SDR dongle was like night and day. I fired up the setup and saw a SNR of 6 to 8 db.
My signal quality was showing 4. Now I was seeing 4 bars at the top. I let the system run for
a few hours and received over 8000 packets with no packet failures.
I also tested both L-Band amplifiers with identical results. I am amazed with the performance
of the RTL-SDR dongle Vs the E4000. It seems to me the E4000 receivers are almost deaf
compared to the RTL-SDR.
