Interference from variable speed HVAC systems

[NickJ]

I thought I might be able to contribute to this forum but there are so many topics I may have missed one dealing with ECM motors and inverter controlled equipment.

I have 9 sources (4 HVAC systems with 2 sources each and a variable speed pool pump) so I have had to deal with electrical noise in the 120 -131 KHz frequency range.

If anyone is interested please respond.

That's a weird post.  What do you want us to do?  beg you to tell us how you dealt with the issue?

Electrical noise and noise remediation is covered in a few hundred threads....

Sounds like a troller vs someone really wanting to add something positive to the members

you're reading my mind.. someone trying to sneak in link spam.  They know with their first post a link in a post will get removed as link spam, so they try to get someone to ask for the link.

He picked the right noise band so educated on the protocol.

A little too educated IMO. Even those on here proficient with insteon really don't get that detailed in regards to numbers

If you saw some of the earlier Insteon users manuals and know X10. Gave the power line frequency. The information is also in the Developers Guide and Insteon White papers. That where online for awhile before disappearing.

Insteon is 131.65KHz and X10 is 120Khz.

There have been threads here on such variable speed motor controls and how to filter it.
