Hello,
I was just curious to see what tweaks have any of you tried to improve reception on your Pro-668. I live in the Washington, DC area (LOTS to scan) - and I pick up stuff pretty well. However, I was interested to see if any of you done any tweaks to improve reception.
Thanks
Speaking as to the 800 only (a cousin to the 668), I achieved a substantial improvement in reception by making the following changes:
Advanced Features > Advanced DSP Settings: > DSP Level Adapt > 52
(I believe the default setting was 64)
Trunked Radio Systems > Trunked System Site Information: > Multi-Site Settings > Site List (select Site) > Low: 15 High 95
(The default settings were Low: 75 and High: 95)
Note: If you set up your TRS as a "Single Site" (I highly recommend doing this), you will need to create a "dummy" second Site (frequencies left at zero) to activate the Multi-Site Settings option.
I first posted this information about three years ago, and a few times since then. Over that time, there have been about three responses indicating improvement and none indicating no effect or worsening of reception.
Personally, I believe that the optimum settings are probably related to one's location, TRS, antenna, etc., and should be determined by individual user experimentation.
