Output level in SNA mode 7 messages
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

Arduino needs update 2 messages
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

Antuino 2.2 35 messages
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

Sweep those bugs 2 messages
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

power measurement observations 3 messages
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
