Hi,

In addition to my post in the Analogue Line Level section, I thought that some readers might like to see another project I'm working on...

This is a general coverage receiver from Elektor (Jan/Feb 1999 issues). It's been hard to get some of the specialist parts in blue but I strive for perfection. Here are some photos:

Dave.

Here's the control PCB...

All the blue enamelled wire is silver over copper. I know that the meter is upside-down, but I don't have the correct one yet - this one is just a space model ;)

The original code for the PIC micro was never made public and there are no pre-programmed PICs left, so I am writing the code from scratch. I have updated the PIC micro to a newer spec and the display to 2 lines instead of the 1 line the original had.

When I get it working, I'll let you all know.

Dave.
