Antuino DOA


 

#antuino

I got an Antuino v2.0 at FDIM last month. I just got around to playing with it. But no joy, it seems DOA. It may work, but the screen backlight does not have voltage. I checked voltage thru the switch with batteries and it reads 9.3v and there are voltages on most of the pins of the display, but none on the display LEDs.?

Any one have any ideas? Or am I just SOL?

The backlight should come up anyway. Can you tell us how you are powering up?

Here is a start:


You may have other problems but check out Mikes note about the power connector. ?Also he may be able to help. ?I have had other issues and will continue to tinker with mine. ?You might try emailing Farhan but he is quite busy now.... working on the final version. ??and?afarhan@...

If the screen is all “light” or “dark” if may just need adjustment of the control pot. ?There is a small pot (variable resistor) on the back of the screen that I had to adjust to get a better appearing screen..... mine was blacker than I wanted so I adjusted the pot to my liking.

Also it looks like Farhan has already entered the picture. ?Great backup of his products.

This is the FUN of radio..... not all things work correctly the first time but learning what can be done to improve something is a learning experience and these internet groups are a God send.....?

Enjoy the ride.

Ashhar,
Thanks for quick response.? Powering up via battery. Getting 9V past switch. ..... Ahh- Found the problem. Bad solder joint on external power connector not allowing negative (ground) lead to connect to board from battery. Corrected solder issue (and reflowed a couple of other joints that looked suspect) and voila! all is well.?
Thanks.

I have been on the fence as to whether I was going to want an Antuino, especially after picking up and YouKits FG-01 for a good price in ebay.

That blog post from n2htt just changed my mind; I'm now in the "can't wait until the're available for purchase" camp.

If you are like me, the FG-01A is the “berries” for antenna tuning and SWR. ?The Antuino has other uses that may be useful for the price. ?Mine is flakey in its operation so more trouble shooting or waiting to see someone else with a solution.
