Here's a tip for setting up the 500 Hz filter if you use one. The actual 6 dB bandwidth is 565 Hz, so in the FLx BW menu I set 0.60. This means the 500 Hz filter is activated at WIDTH = 600 instead of 500. The advantage of this is when you use DUAL PB. That function sets the narrow passband to 150 Hz and the wider passband to 600 Hz. Since the 500 Hz filter is now activated at 600, this means the 500 Hz is in use for DUAL PB, which can greatly help desense problems versus the stock 2.7k, which would otherwise be selected in DUAL PB mode.
