Swr_pwr-meter with PIC 16F88 microcontroller for HF
Project based on DL8UA design and schematics http://schray.de/swr/index.htm and microcontroller ATMEGA8A-PU
Pcb was released on Eagle after schematics : http://schray.de/swr/schematic%20Kopie.gif
simple programming interface for atmega8-P via parallel port
Pcb was made by Press and Peel methode
The design was scaled and printed at 600dpi to an inkjet printer, after that all was transferred by a laser printer or copy machine (with toner)
to P'n'P golden sheet..
Blanc pcb was prepared. The surface must be very clean and dry.
With an regular iron (heat at cotton position) press and keep moving on the pcb for3 minutes
This it's the result. All must be perfect.
populated PCB and project progress
VHF/UHF directional coupler (able to measure up to 40W in 144 MHz and up to 5W in 432 MHz)
First test
