Review on 📻 Nooelec RF Upconverter v1.3 Barebones: Enhance Software Defined Radio (SDR) with Ham It Up. Compatible with HackRF & RTL-SDR; Includes SMA Jacks for MF/HF Conversion. by James Stevenson

I use a magnetic loop to transmit on HF and it takes time to adjust to different bands. With that and a cheap RTL-SDR I can see if it's worth changing the tape. I hooked it up to a short 37ft OCF dipole on my fence and it's great to be able to see activity across the band at once. I had no problems with reception on 40-10M. I also highly recommend adding Array Solutions' onboard AS-RXFEP to protect the external interface when transmitting from a nearby antenna.
