¿ªÔÆÌåÓýYou can do that with an Arduino on a breadboard and a few female to male IDC jumper wires¡ use the attached document (its out on the GITHUB too).? The sketch to do this was written by Oliver for OUR testing of the BPF ? Same goes for the LPF but there are Two ways to do this module.?

The sketch to do this was written by Oliver for OUR testing of the LPF.? The other way to di this is NOT POPULATE U15¡ but populate R8-R11¡ and use the binary code from the attached document to switch the filter path through J21¡ and connecting directly to the TWO filter connectors on the filter board.? Easy peasy. ? I¡¯ll write this up when I have time. ? ? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ ?

Testing filter boards would be very easy if we had a nice widget that had simple controller and an 12c socket ribbon cable plugged into to turn filter banks on and off. Would make tweaking toroids easier for me if rig was not needed. I use SA or signal generator. Maybe build on bread board ?? Build a few and loan them out as needed. Just a thought, unfortunately I am not much on designing nor programming. Tim W4YN? |
