#ATU-10 VK3PE build complete. #ATU-10


 

Hi, I have completed my build and made my first FT8 QSOs today.?

The battery life seems poor, but I may have managed to get low capacity batteries.? There are batteries available on eBay In the UK with wires attached, but they are non-rechargeable so be careful.? I chose to use AA battery holders to avoid soldering to the batteries.? This may give me problems using the case I have ordered.

I was worried about the usb socket shorting to the micro USB pins so I stuck a bit of Kapton tape to the socket before attaching.

My TP4056 boards did not have suitable capacitors (micro USB variety) or only 1 (USB C variety) do I had to order those.

I have no 220K resistors so R19 is two in series manhattan style.

Programming the PIC16F1454 in circuit using my picking required power from the USB.? ?A temporary wire from the 3.3v supply from the programmer to the chip gave me an over current error.

All in all I am very pleased and have another complete set so I will be building another.? A third will have to wait for more relays and mosfets.

I still have 12 spare PCBs if anyone in the UK is interested.? I have sent some to the EU and I am waiting to hear if they arrived OK and if VAT had to be paid.

I found a short that was causing the battery life issues.

Hello Ellis,

How much output did/do You use in FT8 via the ATU-10, I think 5W is possible to much?

Hi Ellis,

I am interested in an ATU-10 board.?
Which PIC's are used on the board?
Details of price please?
I have built the ATU-100 kit and have VK3PE BOM downloaded.

Just got a QDX so will be ideal for that TRCVR.
