Rees, At 1dB/div, a REFERENCE POSITION value of 14 puts a -10dB response at mid-screen. Is that what you are looking for, or do you want a more intuitive entry method? --John Gord

Re: My NanoVNA is overheating
Guys, you have to find your SI5351 max frequency, those 310M is the value I flashed in (for experimental reasons only) because I found out my max frequency is 321MHz..
