I am looking into a remote site with SDR and antenna to take care of RFI. But the SDRs I am trying locally have delays: perhaps 1/4 second for SDR-IQ and almost 1/2 second for SDRplay. I tried both with different software. The delays are too long for running.
Apparently a good remote setup has a delay < 0.1 s. So why the delays with SDR-IQ and SDRplay locally?
Are they due to USB or specific settings in SDR software?
I've noticed a slight delay when hearing an incoming signal via online SDRs ( www.WebSDR.org
) compared to my regular receiver. It's not enough of a delay to prevent a QSO however. Many times I can hear the other station better via the online SDR than I can at the base, because of high local noise levels.
