Is it impossible for Chanalizer to detect and recognize 14ch in the 2.4GHz band?  
It appears to be within the range of waveforms that Wi-Spy DBx is picking up.

Hi @monochromeweb,

Chanalyzer has two data sources. The spectrum analysis data comes from the Wi-Spy DBx, and the Wi-Fi scanning data comes from your Wi-Fi adapter. Since channel 14 is limited to only HR-DSSS modulation (which dates back to 1999), it’s possible that your Wi-Fi adapter does not support Wi-Fi scanning on Channel 14. I would check to make sure that your adapter supports Channel 14.
