BCD436HP/BCD536HP: P25 adjustments bcd536

[dwelluppon]

I would like to try to adjust P25. I pressed funct. then vol. to bring up the error rate. I am set to 8 auto. Im getting an error rate of around 15 at it's lowest number 25 at it's highest number. Should I set the P25 rate to manual then adjust the rate to highest level, lowest or take an average?

I've got mine set at manual. It seems manual with 7 for level, is the best for my location.

I have error numbers. This allows the right adjustment rate. Im asking what numbers to use. Low, high or middle. After I set the rate, let's say I go low and put 15. Do I keep it at manual or back to auto? What I don't understand since it's set to 8 auto, will auto work better with the different number?

When set to 8 Auto, the adjustment will start at 8 and then try to adapt to the value with the lowest digital error. If you are receiving a simulcast site, the setting can jump all over the place trying to find the optimum value. If you set it to manual and run through all of the values to minimize the digital error, the scanner will start at the optimum setting and stay there.

That makes sense. The numbers start high then drops to the low number. Not all over the place. This gives me a starting point. Ill start at 15 manual since it is the low number. Thank you very much.

There is no "One Size Fits All" when it comes to P25. It is dependent on many things.

My neighbor has the very same scanner I do, listening to the very same things. For him to get the most desirable audio, his P25 settings are different.

It will require experimentation with different values and then pick the one that best suits you.

For me, I go by what sounds best versus looking at bit error rate. I also use Manual. I've found it to be more consistent than Auto. While in Auto, the scanner starts at the value you select, then continuously tries to fine tune on its own. That can often be annoying as there are differences in the sound. With Manual, it stays on the one setting.

I go for the clearest sounding audio also.

Ill spend the today adjusting. The numbers start high then lowers so I might start off today with a very low average number and try auto cause the range is so high. Ill come back at the end of the day and give results. I will also adjust the time from 400ms to 600ms. Thank you.

Typical of simulcast distortion. Best of luck to you!

We are back to the 1970's when you had to trim the crystals in the Regency and Bearcat Scanners to get the best reception.
People in town used to ask who I monitored when I told them they said well I do not get them or they do not sound good I would take their scanner tune them and they were happy. Same thing now you have to spend the time to setup your scanner if you want it to work at its best.
You also have to use the correct tool for the job desired.
