Anyone have issues with capacitive touch controls on equipment when transmitting? I have a Samsung soundbar in the living room over the fireplace, and it's about 30ft away from the antenna, but when I transmit, it either changes audio inputs, raises the volume, or lowers the volume. Unfortunately it never turns off, lol. It's not so much an issue for me as it is for my fiancee, since she's usually trying to watch TV when I'm downstairs on the radio.
It's connected via optical, so it's not coming from the TV. Does anyone have any suggestions? I've tried grounding it, but that doesn't help. I'm considering putting some foil over the "control area" on it. |

15m is the band that gives me fits.....anything with a wire, cable etc.....I end up putting on snap on ferrites. #31 mix ferrites
If your item is wireless (optical) etc.....I am not sure what you can do. |
| Touch lamps have always been problematic. They sometimes generate RFI that your receiver will pick up. They can also activate when you transmit like you're seeing. My daughter brought a touch lamp into the house without me knowing and then thought there was a ghost in the house one night when I was on the air. Every time I transmitted it would change light levels and it was driving her crazy! She now knows the rule of no touch lamps plugged in when I'm on the air. |

So, whenever I transmit, doesn't matter the band, either the audio "dips" or the input on the soundbar changes. Grounded aluminium foil covering the buttons doesn't work to stop this. I tried grounding the soundbar to the TV using test-leads, but that doesn't work either.
Dipping: It will drop for the duration of my transmission. It can be 10w of carrier for tuning, or it can be 100W of SSB, doesn't matter. 160m-10m. This is kinda expected with any unshielded ampliflier. Unavoidable in my instance, and I'm willing to accept that. Input change: It will change the input, akin to when someone puts their finger on the "button" to cycle through the inputs. There's gotta be some way to fix this. On the plus side, my motion sensing lights on the deck don't go off every time I key up on 20m, but they don't turn on anymore either... So, yeah. I'm out of ideas. Maybe I'll open up the soundbar tomorrow night and see if there's anything I can do to "reduce sensitivity" or something. I thought about opening it up and unplugging the capactive touch sensor, but then I'm unable to change inputs entirely (only one input is used currently, but I'd rather not have to open it up again to change inputs.) |

Yep, I have one of those and pretty much anywhere in the south side of the house (antenna side) it'll change levels when I transmit even as little as 10W to tune up. |
