That’s LS’s position, but I’d need to see some evidence that my Garmin is indeed accepting interference from a different band.
Read the report and produce evidence to the contrary. It’s perfectly possible that LS is overstepping its band, but I haven’t seen anything to that effect yet.
I read through the opposition’s site, no claim of LS overstepping frequencies, only a complaint that the power of the signal on an adjacent band causes problems in the GPS band. However, even this only causes problems with a minority of GPS devices, so logically the difference must be in how the GPS devices are built. The explanation that some guard against reception of out-of-band signals and some don’t is the most logical I’ve heard. I’ve built radios, but I’m not an RF engineer, so I’d appreciate any further education on the technicalities.
