Hello,
I used to work with a high power HF system that tied into a LAN a couple of
years ago. It used some HF email software from Harris and they supplied a DB9
filter that allowed you to remove the DB9 from the serial port and attach the
filter between the computer and the cable. It was a male to female DB9
connector that had small RF filters in it and was manufactured in Mexico about
1/2" long between the male and female DB9's. They also had a DB25 version but
I only need the DB9 right now.
Has anyone information where I can obtain such a filter? I have suspected
RF hash on a cable with a DB9 that I need to filter out. I would like to try
this option before using a bunch of clamp on ferrites. If I have to go to
ferrites later that is fine but I want to use these filters first.
Advanced Thanks,
Mike
