So the final test for pc reception was using the Nooelec SmarTee V2 with the Nooelec Sawbird+ NOAA 137 MHz pre-amp and filter. The results are shown in the two images below. Pretty darn good I think you’ll agree!
The filter appears to clean-up the image once you have a decent signal. Superb performance for the Smartee combination.
That concludes the PC tests. Next indoor steps are to get the Raspberry Pi 4b decoding passes with the SmarTee/Sawbird combo and outdoors to get the turnstile antenna up.
