Hi all..
I seem to be seeing more and more crap turning up inside the 70cm Sat segment of the band, where I was in the past having no issues gathering the TLM form Sat's its now getting harder and harder.
Using HDSDR the floor was around -111dB as indicated . with intermittent bounces in the Floor level.. and also with intermittent bursts of other TX .
Would be interested to hear from other on there situation, and if they managed to clear it up and how.
One issue of mine is, using a wideband preamp up front, this really cant be helping, was looking at tossing in some filters, or coax stubs to see the effect of block noisy signals lower down in Freq.
