RX troubles...

[N2DTS]

Its working quite well.
No signal gain is low, or rather the background noise level is very low.

[N2DTS]

Used it all day today and it is working great.
I bridged all three receivers up using 1 to 2 splitters (.2 to 300 MHz) and feed them all into the Marantz audio amp.
I can switch between them very quickly, home brew 1, home brew 2 and the sdr-iq.
I get scope outputs from both homebrew receivers but number 1 looks a bit funky for some reason, a slight bit more response in the upward direction on the scope then the downward direction...?

They all sound good, #2 sounds a bit better for some reason, the sdr-iq has a lot of background hash on weak signals.

Since I have a fan dipole for 80 and 40 meters, I can put one RX on 80 and one on 40 and just switch the audio to listen to one or the other.
Listened to a nice round table on 3885 in the afternoon while playing with a modulator.
Then worked K9LPA on 40 meters without tuning anything...
