I do not see it as a problem.
I use a splitter and run two receivers at the same time.
The homebrew, and the sdr-iq.
The audio is about the same on both receivers, the homebrew does a very
little better on weak hard to copy signals.
The homebrew has an IF output that goes to the scope, so I can look at my
and others modulation waveforms, the sdr-iq has a nice band scope so I can
see open spots, someone off frequency, where the qrm is coming from, how
wide my signal is, and other signals width.
I can also click the mouse and jump around, use the sync detector, and
adjust the filters to whatever I want.
All I have to do is switch the audio between the two receivers.
I do not see much use to bridge two normal receivers together, other then to
Separate antenna's would allow some sort of diversity reception if you mixed
With the splitter, I get a slight loss of signal strength, but the receivers
do not interact at all.
I also have a Peaberry V2 sdr, and tried to split, then split, to have 3
receivers on one antenna, but I think that did impact the receive quality a
I do not think it would be a good idea on higher frequencies.
