Need a little help here. Please listen to the attached mp3 (I edited out an address). Its a short transmission I recorded from my Pro 164. That very specific interference is happening on any system I listen to with frequencies around 866.4250 through around 868.4375.
File is here: http://mrose.org/867mhz_interference.mp3
Frequencies around 860 through 865 or so are unaffected.
This occurs on two separate TRSs within range. However, the condition exists when monitoring the channels conventionally. Both the systems have frequencies in 860-865 and 866-868. Fortunately, both system's control channels are always in the lower channels. When the system lands on a higher channel, that interference occurs.
Reorient the handheld horizontally seems to weaken the interference and allow the channel to be heard.
I don't expect anyone here to make the interference go away. I am, though, looking for your best guess based on what you hear. Would a better antenna setup improve this situation? Does this sound like the scanners being bombarded? Or??
Any input is much appreciated!
