Riddle me this ...
I'm sitting at my desk and my handheld is sitting on a wood shelf
just behind the HP laptop.
The HT is on and set to monitor 146.670 (it has long thin flex antenna).
All of a sudden the squelch opened to static.
I walked around with it and it seemed that the source might be the
inline UHF amplifier that feeds two rtl-sdr devices, or the cellphone
repeater. Note: Both devices are located on the other side of a 4x8'
steel door from the handheld, laptop, and me.
When I sat back down at my desk it was quiet, then when I moved,
it started, again.
Yup, it's responding to the position of my body relative to the laptop
and mouse.
Sitting back, away from the desk opens the squelch, leaning forward
quiets it.
WDYT?
