Oristo & Rune, Here is an interesting HP application note. Refer to pages 7 & 8 for explanation on using different scan steps on specific segments.

Depending on the firmware you load the uncalibrated uncorrected S11 and S21 make little or a bit sense. Unless you want to understand the calibration process do not look at uncalibrated and

I changed the subject, as it seemed that we are no longer discussing the 180 degree item... And...I hope that I got this correct...still getting organized here wrt all the versions and programs. I

Dino, Could you please add me to your list of those interested in info on both of your projects? fhh11@... Tnx es 73, Floyd Hollister- K2DUV

The SMD 50 ohm loads arrived today. They measure 51.15 ohms each (I screwed through connectors in to make sure the cap was making firm contact with the barrel) which is about 2.3% out. I guess they

I used the method described here: www.iw2fnd.it/sites/default/files/docs/Trappole_01_EN.pdf ... and I compared the result to dipping the trap with my Heathkit Grid Dip Oscillator. The results were

Hi Bob,You can buy several chips at a time( like 5pc) from China or you can do a transplant from a cheapo power pack from a dollar store as they sometimes use the same chip. Have a look at this post:

I will try to sort some light-weight filter I glued nanoVNA shell command Python script: https://oristopo.github.io/nVhelp/html/nVcmd.py .. with a bash script to get 100 values at some frequency: $

Seems a good choice, if DIY unit parts costs exceed half that, and the intent is actual use vs fiddling.

Hi The RFzero may be exactly what you are looking for: http://www.rfzero.net/ The RFzero? board is an Arduino compatible GPS controlled Si5351A RF signal source. The typical use of the RFzero? is

Hi Rich - Oops, I first asked for cubic fit, but gnuplot was not converging well, so dropped back to quadratic, which IMO fit well enough to estimate RMS noise. I habitually use cubic for piece-wise

Hi All, Most likely out of the price ball park but I have just ordered a moRFeus - RF Upconverter and Downconverter, Wideband Mixer and Signal Generator. https://othernet.is/products/morfeus-1 $99.00

Tcxo-s have long and short term drift. Short term drift better. Many precision time signal source available on shortwave. Easily measure drift if you have good ssb receiver and computer. Tune 1 khz

This is actual for simple crystal oscillator with large error. But NanoVNA uses TCXO which has temperature compensation and small error. I don't think that it will be easy to add correction for TCXO.

Get screen protector for any cell phone that is large enough and then cut it to right size for NanoVNA. -- 73, Pedja YT9TP Checkout: https://pedja.supurovic.net/ https://yu1abh.uzice.net/
