Can Antuino also be used to find the best possible location and orientation for an FM - DAB+ roof antenna (VHF band II and band III)? If so, how? The idea is that my hifi tuner is down on the ground f

I replaced the battery holder for 6x AA cells with a holder for 2x 18650 Li-Ion cells and using two 3.7V/9900 mAh units. The Antuino holds for long hours, actually I never get the batteries discharged

I plan to use my Antuino for RFI sources finding. My QTH is very noisy, full of LEDs with dimmers, switching PS etc. like another mid-city location. What will be the appropriate sensing antenna, do I

Good evening all, I recently received my Antuino. I installed NEW batteries, but the unit did not power up. I then plugged a powered USB cable into the Antuino and it cam up and worked perfectly. I th

Hi, I have a Antuino that I have determined is -17 db with a coax running from the in to out. Does this issue affect the accuracy of every function ? And has someone posted photos of where R20 is and

Hello, I bought an Antuino, but I am not that tech savy and should have went with something a little easier to work. I can't even figure out how to do a simple SWR measurement. So My loss is your gain

To check whether you need this mod, connect the two SMAs by a short cable and select SNA mode and my reference 20MHz. The reading must show -20dbm +-1db. If it shows anything like -17 or -14 then this

Hi. The pre-built Antuino I ordered has arrived, and have to say I'm very impressed! Eventually (no info, not even a link printed on a bit of paper was included, but Google of course is my friend.) Pe

Is it possible to use the Antuino on 630 meters? I would like to use it to check SWR etc. Anyone done this? 73 W0PT

The schematic shows a Fairchild LM78L05ACZ voltage regulator rated for 100 mA. For 5VDC output, the max input voltage is 30VDC. What external power supply are you using? All Electronics has switching

I really like the Antuino, and this version looks great. Has anyone been able to get the new sketch from EB7ME ? Or, did he use something from Ashhar ? https://youtu.be/VTyHUfMKoz8

Esteemed reflectees, I plan to use my Antuino with a small differential loop antenna for finding the local noise sources (switching PS, traffic lights, LED strips in the neighbourhood etc.). I would l

Having a lot of trouble finding useful readings. Have FDIM unit that has had h/w modified to v 2.1 per Farhan's suggestions Firmware 2.1 uploaded to unit. Calibration redone. It appeared to work well

Hello again. Many thanks David, Carl, Gary and Raj of course. It's compiling now without error, using the ide version 1.8.10, running on Mint 19.2 64 bit. I get this in the status text window when it'

Hi. Like many others (so I see from some time with google) new to the Arduino IDE (successfully installed and working with other demo projects, and simple trials of my own etc.) I'm having trouble fig

Farhan, Last Saturday the parts mailed from India arrived. Today (Monday) the parts mailed in the US arrived. The first envelope must have been in the Windjammer sailing ship and it had to go around t

Hello, I have two questions about DIY'ing an Antuino. Which material is used for the toroidal inductors? FT37-43? Can I use this ( https://www.ebay.nl/itm/KS0108-128x64-Graphic-LCD-Blue-Backlight-for-

Hi all, I built my Antuino with as many as possible standard components through hole. This is how it looks Rob PA0RBL

I used a recently purchased Antuino on an EFHW project. I built a 1:49 transformer, connected it to 135 feet of wire, and hooked up the Antuino. The wire is too long, obviously, but I'm getting incons
