【Daily project update】3D data for checking clearance of assembly

3D data is a good feature for checking dimension of PC-Board in term of mechanical.
After make position of PCB such as assembly part to board. Some parts need area for those bodies.
Many parts are OK to plate on board if dimensions of parts are correctly.

PCB Program; Design Spark PCB

3D Program; Solidwork with Circuitwork feature.

【Daily project update】draft pcb actual side issued

Completed  a lay all components to 100x120mm. PC-Board. This side was small, components will close and track are difficult wiring. It's may clause interference between signal. Next check all components in market.

Update PCB for sdr

After revised circuit of SDR. Circuit idea from YU1LM and I improve a oscillator for using AD9850 module. Side of PCB applied for aluminum case 100 x120 mm.

And idea for Font-end may I separated box for control

E22ICQ

Building SDR Board.

This is SDR circuit base on Softrock TX/RX ensemble but find a local components. Target a project for using in VHF band. So step by step for design.

SDR tranceiver

SDR for ham radio is growth to recommend in shack. I have a peaberrySDR and home-brew SDR HF receiver. Now I try do a build my own design. target is for using in VHF band that is for moon bounce experiment.
