I read in some messages that the output level should be -20 but mine is -25. I checked R20 resistor value and it is 470 ohms. Shorting out the resistor will increase the output to -23. Is there any ot

Hello, I have version 2.1 purchased at FDIM 2019. I am upgrading to V2.2 hardware and software. In the instructions for the hardware upgrade to V2.2 there is a step to place a 10 uh inductor in parall

Greetings. I just joined the group and was wondering what changes have been made to version 2.2 from 2.1. Also, I have read something about a ten turn POT but have not seen any info as to the reasonin

I have an "old original" Antuino that has not had a firmware or software update. I find the prospect daunting. Is there a place to send it, at reasonable cost, for updating? Alternatively, is there so

FYI. Peter VK3YE posted a nice Antuino review video here: https://www.youtube.com/watch?v=VHX54oyCTEM 73, Mike KK7ER

I downloaded the 2.2 from GitHub. The glcd.zip file says invalid, and won't open. I got another copy of it, and that one is fine. When I compile, I get antenna_analyzer_p5:2:10: fatal error: fonts/all

I have checked my 2.2 antuino. The power level changes with the scan width. With a scan of 300KHz and below it is -21dBM..(as adjusted in the attenuator) If the scan is 1MHz and above it varies from -

HI ALL, GOOD DAY. Any body having the SCHEMATIC/CIRCUIT DIAGRAM FOR ANTUINO or the connected link, kindly spare Thanks in advance 73 MUTHU VU2LMN

DEAR ALL, GOOD DAY TO ALL. In my Antuino analyser, the RF INPUT Connector came out along with the BNC plug leaving a "L" shaped pin as shown in the Figures 1, 2, 3, and 4. It seems that the SMA right

Fix works OK on my antuino Colin G3VMU

Using Antuino V2.2 there is a bug in the doSweep() routine in file plot.ino. To see the problem, set mode to VSWR, Span to 30M, Frequency to 120. The first trace will show the correct return loss, but

HI GOOD DAY TO ALL. NEW YEAR GREETINGS FROM INDIA. Today(01.01.2021) I measured the SWR of my antenna system using ANTUINO ANALYZER. It is observed that there are very wide variations in the SWR value

Hi Group, Just wish to confirm, do I need to match those 25Mhz crystals just like SSB filter? if so , how close I need to match ? 100Hz? Regards, Ew

Hi Group, I'm new here. Here's my homebrew antuino: A fun project to build ! Thanks for the great Antuino design. I have a question here, is it possible to implement / show impedance of antenna in ohm

Cant see the pictures on the group site at the mo, but the two peaks probably indicate the Antuino's RX filter is not setup too well, or there is a bad solder joint so some component is not making goo

Just received an Antuino, I think it has V2.2 on it. One issue I notice is that when I go to the menu and select frequency, (the 1 MHz field for example), I press the rotary encoder switch in and hear

I have a new Antuino that came loaded with ver 2.2. First time using it, I attempted to check the SWR of an antenna. I am connected to the rf out. I've attached pictures of how I configured the unit a

I have a recent version of the antuino with the latest software. How does one make the connections to take advantage of the "Vacuum Tube Volt Meter" feature? Tom AB6TN

It turns out one of the problems I have been dealing with was faulty board mounted SMA connector for the "RF OUT." As with many electronic devices, it was a physical connection problem. The Antuino ap
