There was recently an article in QEX (ARRL's print mag for

The qvna software is at http://dl2stg.de/stefan/hiqsdr/qvna.html and

Loss Bridge that's been designed for it.
I haven't used the RLB but I have used qvna to check my HF quad using
the HiQSDR.
N2ADR also includes a python version of qvna in his quisk software at

The HiQSDR by DB1CC is based on Jim's design that was published in QEX
and also desribed on
