[hpsdr] [OT] Hermes VNA calibration

[AA8K73 GMail]

What is a good 50 ohm termination to use for Hermes VNA 
calibration?

The open and shorted ones are easy.  When I calibrate with a 50 
ohm load and then measure other 50 ohm loads, I get variation.

I've tried a Decibel DB4303B, Relm T44100, Bird Termaline, and 
various, small BNC terminators.

Where can I find a 50 ohm precision terminator that will be flat 
on HF to 50 MHz?
