In attempts to tweak the IF Gain (6 total) on a Nooelec NESDR Smart XTR, I’ve read the SatNOGS SDR setup guide and associated manufacturer data sheet.
The SatNOGS SDR setup guide offers this starting point for a E4000-based SDR such as the Nooelec:
This works without any modifications and yields decent observation results in terms of both the waterfall and generation of data frames for most satellites when compared to a RTL-SDR v3 blog that was in place for months prior to the Nooelec SMArt.
Why are there two IF2 parameters listed in the SatNOGS example, is it a typo? The Nooelec spec sheet show the possible setting for IF2 as 0,3,6,9 (not 2)
I’ve also tried changing the parameters to all 6 IF settings but do not see any difference but will keep messing with these.
I have noticed some satellites signals are now very weak and I can barely decode any frames from them any longer (FALCONSAT-3, BOBCAT-1 and RAMSAT-1 for example) when compared to using a RTL-SDR v3 blog for months with the same system and decoding tons of frames in single passes. Hence why I am trying to tweak the Nooelec IF gain settings.
Any insights would be greatly appreciated. Thanks.
