Thank you very much for the quick response, I appreciate it very much.

For the missing facts, Linux Mint runs on a 64bits Dell Optiplex 380, desktop PC and Wimdows10 on a 64bits HP pro, both machines are a bit older but because there are only the OS itself and LigtBurn installed drivers they are very fine.

The Mini-Gerbil controller can well be “supplied” from the Computers, ie. led1 and led2 are on (flashing)

I’m having a bit of a problem with the Linux commands you’d asked me for, it’s been a long time since I’d used Linux, sorry. It is “output from here” that is causing me problems.

Yagi-Uda antenna analysi program output, version 1.19

Written by Dr. David Kirkby Ph.D. G8WRB (email:david.kirkby@onetel.net)

USAGE: output [-cehps] [-E E_max -H H_max -r min -R max -Z Zo] filename

Where options are:

-c Calculate sidelobe levels (slows program considerably).

-e Suppress calculation of 3dB E-plane BW.

-h Suppress calculation of 3dB H-plane BW.

-p Put data into filename.freq, filename.glog and filename.glin for gnuplot

-s Suppress diagnostic output.

-E Max angle to find the 3dB point. Min=90, max=180 (default = 179 degrees)

-H Max angle to find the 3dB point. Min=0, max=90 (default = 60 degrees)

-r Set minimum range on the radial gnuplot log graph (default = -50 dB)

-R Set maximum range on the radial gnuplot lin graph (default = 20 dB)

-Z Set characteristic impedance (default = 50 Ohms)
