In Reply to: Improve noise rejection? posted by danda on October 31, 2001 at 21:35:50:
Hi,I was one of the ones that posted a response to your original post. I had guessed that the VCR may have poort RFI rejection and it looks like that may, indeed, be the case. There are couple of cheap tweaks you can try before you buy a new VCR.
Assuming that the case of the VCR is all metal, the most likely cause of RFI leakage into the unit is the numerous cables that feed in and out of the unit. Try placing one or more ferrite rings on each of the cables (power, signal, etc.) that feed in and out of the case. The rings must be placed around the cable as close to the unit as possible. You can buy these rings at www.audioadvisor.com or similar sources.
I have had RFI problems with home built components in the past and these ferrite rings were effective.
Another thing to consider is to make sure that all cables plugged to the unit are shielded. If you have any line-level cables (e.g. RCA-terminated interconnect) connected to the unit, make sure that they are shielded types.
Good luck.
