[PPRAANet] source of interference

[Derek Brown]

After reading these, and just converting my entire garage to LED today.. I figured it was time to play with my Tiny SA. Set it to 2Mhz to 50 Mhz with a telescopic antenna. Yes I got some spikes / waterfall streaks if I got near the new garage fixtures (not as bad as I expected but they registered for sure). Why stop there? Also put the unit next to every piece of electronics in the house. My biggest offenders in order are 1) Cosori air fryer / in stand by - not running (this thing puts out the nasty! Was really surprised at this. I unplugged after..) 2) my computer monitors (right next to my radios!) 3) my living room flat panel, yes LED, TV. I don't have any noticeable RFI issues at this time but can guarantee these devices don't "help". Happy hunting!

I have had mixed results with Feit brand LED bulbs. Some seem fine, others are noisy, even among the same model. I had one down in the basement and my radio room is upstairs on the second floor, the antenna is in the attic and offset by about 20 feet. The interference was significant even separated by that distance, so even a bad bulb in a neighbor’s house could be an issue.

For the past few months, I've been receiving interference on the 2-meter
band -- it sounds like power-line interference, and is strong enough to
interfere with some of the weaker 2-meter FM signals.
Today, I finally got off my butt and tracked down the source.  It is
coming from two 8.8 watt LED bulbs I used to replace old ones in the
kitchen (regular bulbs, not like the fluorescent tubes).  They are Feit
brand -- think I bought them at Ace Hardware.

So if they want to sell you Feit, put up a fight (or something like that).

BTW tracking the source was simple.  Since it was on the 2-meter band, I
switched my Yaesu FT60 HT to the AM mode, and walked around until I
located the source.
