[RFI] CyberPower CP1500PFCLCDa - Bad RFI

Fri Jun 16 15:33:46 EDT 2023

I just received a new CyberPower CP1500PFClCD and it's broadcasting strong RFI on the HF Ham Bands.  This particular unit was assembled in the Phillipines. I'd estimate the tone/buzz the CyberPower UPS is broadcasting to be aprx. 3,000 to 4,000 cycles.  The strongest interference is on low bands: 160 meters is worst, and interference gradually decreases in strength as I increase the frequency of on my receiver, but the tone/buzz can be heard on all ham bands 160-10m.  (though much weaker on 10m)  The tone/buzz frequency and strength seems to be changing, possibly decreasing, the longer the batteries are getting charged.  The unit has only been charing for an hour so far.  I'll leave it charge over the weekend and report again on Monday. Have a nice weekend! 73, Dick- K9OM  In a message dated 6/16/2023 11:00:10 AM Central Standard Time, rfi-request at contesting.com writes:
