APT Wx Sat Reception

I have been watching a few videos on APT sat decoding and since I have a couple of sdr receivers ( hack rf and sdr uno) I thought I would make a start one a couple of filters ... the 1st I've made is a 137 Mhz bandpass which doesn't look too pretty but she definitely has all the curves in all the right places ....

SMD's populated

Coils are a bit too long but have tweaked centre band nicely

So here is the curves ... judge for yourselves

Tried it on the new NanoVNA-f and I was quite impressed with the quallity and how close it was to my Rigol 815

Here's the Smith's chart showing what I expected.. capacitance and a little inductance ... ( well that what the filter is made of )

Sorry for the time out

 

Hi all sorry but I have had a lot going on in my life ... I have still been a busy boy but have took a break from the blog.... I'm back with a few new things I've been upto to keep you all upto speed.

 Well I was diagnosed with high cholesterol and blood pressure and was told to change my lifestyle ... so I've been out walking every day and it had changed my life.

No need for tablets anymore and a few sizes smaller
