Hello Herb, The filter is connected to both ports? Can you tell me what I have not done please. Cheers Kev

OK, since you ask, but I find yours much simpler to follow

Sure it does. You just need to polarize, filter and modulate the beam.?Hmmm, starting to sound like a laser link ;-) On Sun, 26 Jan 2020 at 2:47 PM, David Eckhardt<davearea51a@...> wrote: IR

Merci Beaucoup Jose, Te souviens tu si il y avait aussi un moyen de contr?lé le générateur par le port USB? Pierre VE2PF

A few years ago I and another OM (F1VL) we remade a firmware for this, the code is here: https://github.com/joseluu/STM32F103_TFT_LCD_ADF4351 The code (Inc/board_config.h) indicates that the display

Dave, This effect, of nearby AM broadcast stations, makes it nearly impossible for me to do vna measurements on my 160M antenna :-(? I built a 1.7 Mhz HPF for the analyzer but it did not help much.

The best way to measure the impedance at the antenna is to use a multiple 1/2 wave coaxial cable at an appropriate frequency.? Stay on the ground.? When I am designing and building new antennas, I

Hi John - I would try communicating by shell commands; see: /g/nanovna-users/message/10215

Hello Dave, Here is 2 pictures for you to view.

I went directly to attached to the USB.

Hi Dave - Sorry. I should have said "worse clone reported about -72 Ohms reactive and 1 Ohm resistive" See attached image for repeat of Herb's steps with slightly different results, but still no "j".

That should be -j72 ohms. Proper and good use of a VNA involves respecting the sign of the complex portion of the impedance measurement. -j implies capacitive and the below the central horizontal line

IR doesn't work too well in sunlight. How about a neutrino beam from the LHC? Dave - W?LEV

I test older version wifi only instrument. Extreme useful. Wifi works on long distance. Easy measure antenne feedpoint without long coax cable. No any interfetence up to 70cm. I think wifi/bluetooth

Did you read the original message #8655? Let's try to do it step by step. ))) Switch on NanoVNA and connect a piece of open ended cable to CH0. No matter what is the length and Vf. In my example,
