Balun needed for coax fed dipole on hi-z port?

Hi - I'm very much a beginner here, and plan to build an inverted-v dipole for use with my SDRplan RSP2. I understand the hi-Z port has an impedence of 1k Ohms. Does this mean I would not require a balun if using a relatively short (say 10-20 meters?) coax feedline to the dipole? Alternatively if I ...

If I have multiple VRXs running (2-3) and zoom any of them in to the maximum, the audio drops occurs. Anything lower than full zoom and I can run a higher sample rate no problem. I am wrapped with t...

In SDRuno, if I set SR (Mhz) to anything above 2Mhz which gives me an IF BW of 1.536Mhz I get chopped up audio. The Sys utlization reported in SDRuno...
