Over on YouTube user Mile Kokotov has uploaded two new videos that show both the SDRplay RSP1 and RSP2 receiving VLF, LF and AM BC signals. The SDRplay RSP1 is a 12-bit SDR that can receive from about 10 kHz – 2 GHz. Recently the RSP2 was released which is an upgrade over the RSP1 with additional filters and features. On this blog we did an initial review of the RSP2 and found mostly improved performance over the RSP1.
SDRplay RSP1 and RSP2 comparison receiving Time signals on 60 kHz and 77.5 kHz in Macedonia.
In this video I am using Delta Loop antenna 43 meters long with 25 meters RG-6 coaxial cable.
Antenna on RSP2 is connected to its Hi-Z port.
