RTL-SDRv3 when does it start receiving?

Post by KC8DVE » Tue May 19, 2020 12:19 pm


I am using the RTL-SDRv3 with SDRuno for receive only. Can you tell me does the RTL start receiving as soon as it is plugged into the usb port or does it not start until you press play in the program? I am curious to know if I click stop in the program can I then transmit on my transceiver without hurting the RTL or does it need to be unplugged from the usb while I am transmitting? Separate antennas but only 10 feet apart using RTL-SDRv3, SDRuno on windows 10 - separate standalone transceiver not connected to computer but quite often transmitting at 60-100w..

Thank you

I would get a switch to disconnect the RTL-SDRs RX antenna while you transmit. Even if it's off, high TX power is still going into the chip which could damage it.
