fider?,do you mean feeder by any chance?.

Hi bill,no it was a kit so was an oversight by me,i just wondered if that would cause the no responce to rf or if its a firmware fault etc.

Nothing wrong with the tuner I think, just not enough ground pole. Try to Google "artificial RF ground system". Or, add that length of coaxial with the better results, can control it with VNA. Couple

well that is not what i had thought. thanks dave

Hi. Ic 705 tuner connection. One pin is the tuning request from TRX Second pin is the CW request from tuner According to well known icom tuner protocol.

I'm using a ATU200 ATU, that can operate up to 150 W and uses a weather proof case. (

as the heading says a bought an atu-10.? it has a connector on the back that is labeled "ext".? any idea what this is for?

Unconnected antenna socket grounds sounds odd, Paul. Did it come in a metal case?

Attached is my firmware as brought from china,Let me explaine i built the tuner but it did not react to rf,on taking it apart i discovered that the antenna socket grounds were not connected to the pcb

Great job! Finally got a PicKit3 to give this a try, it works a treat! ATU-100??? EXT board by N7DDC??? FW ver 3.2 PWR=0.0W.L=0.45u??? SWR=0.00 C= 147p PWR=0.0W.L=0.45u??? SWR=0.00 C= 147p

Hi Rob, Watch out for L1, as some boards have smaller diameter holes for L1, so you can only fit the 0.5mm wire. I'd also look at using the -6 toroids as they are 55MHz rated (but you'll need to

Hi all, this is great. I also have no PIC experience but now I feel like I can get hacking on it when I have some time free. It seems like the ideal target would be a common (serial or i2c) protocol

Hi Tom, Great work.... I've been messing with hardware and base code to add frequency and memories, which takes this towards a consumer tuner. But there are a lot of "standard" boards out there that

Hi Edson, When establishing serial communication I'll not use LCD, but I find it useful to be able to connect the LCD while doing tests with arduino. If you prefer to try it with your code, for my

Hello German, Yes, I deleted some routines on the code, including the I2C/LCD sending functions. That was because the original code isn't very well organized and while doing the modifications I was

Rob, if it is 1mm you can leave it

Thanks Edson for your comments and support. Arduino seems easier for me because there is much more information and code with examples of what I intend to do. I am testing your code with MPLAB, and I

Ok, but still keep the same diameter as original wire with the atu100. ?Get BlueMail for Android ?

Enamelled copper wire, so called because its early application was to wind electro-magnets.
