Hi Glenn,
Exciting news indeed! Is it possible to get one here in the US? Let me know.

On another note;
The board you sent me does not have the MCU. It looks like one was installed but either taken off or somehow fell off (Which by you soldering technique, is not possible). Was there a problem or did you need to cannibalize it? Just curious.

I look forward to hearing from you as the larger spacing pitch is much more preferable for these tired old eyes.
Or¡­ Are Gerber's on the horizon?

Take care and thanks for your work. It is a valuable service you are offering to the Amateur Radio community!

Hi All,

I made a pcb version that swaps all the 0603 sized parts on the ATU-10 PCB to 0805's.?? Maybe still not 'big' enough to satisfy those hesitant about smd work.

I received the PCB's a few days ago and have not loaded one yet, but the Sch is identical to my previous versions.

Details below, what is different about the V1.31 ATU-10 PCB by vk3pe, over the V1.2 that I released gerbers for.

  • As before this PCB is modelled on the original by N7DDC.
  • All resistors and capacitors are now 0805 size (were mostly 0603)
  • 4 mounting holes added if builders want to use a different case.
  • PCB still fits into three sizes of extruded aluminium cases. Ie 100x71, 100x82, 100x88mm.
  • ? Alternate holes provided for BNC sockets with 10.05mm pitch ground pins (Vs 6.6mm original)
  • Top pads added on unused Port pins of the PIC16F18877. (no current use)
