Hi Richard,
?
Great! That's looking much better than mine indeed. I'll use your settings and see if it reflects the results, and do some more tinkering.?
?
There is an interesting article on the web:
Yes I know about the article from KA7OEI. I think it's great. I used it to fine tune my rx2fits / rx2fits2rss setup, mainly used to capture solar events. A Pretty straight forward setup come to think of it. There is not much of a calibration involved.?
?
I'm also very happy with the helpful remarks from Larry.?
?
The Dark Sky Observatory is best described as "quite rural".? In that case the noise floor may be -130 dB or lower.? In more noisy environments it can be quite a bit higher. ?The?dB Threshold on SDRc2RSS corresponds to that noise floor, and one should not raise it above the actual noise floor else some faint signals will be lost.?
Noted! I'll use this as a rule of thumb.
?
I think I have to recalibrate my different setups. ?
The environment I have to put up with residential (rural) so I have to live with a higher noise floor.
?
I think trying out a small amount of pre-amplification is a good idea, and I have ordered an RF pre-amp and will give it a try when it comes.
I tried different pre-amp's. Most of them give about 20dB and couldn't find one with less amplification so I had to put attenuation inline. I do not like that setup, mainly because of the necessary attenuation. I wish I could find an adjustable one or one with less power.
