Not Able to Receive P-25 Phase 2 transmissions.

[daveo89]

davo89, when dealing with Simulcast, enabling Global Attenuation only on the Simulcast System should limit the number of towers that your radio will receive when scanning this system and will not alter the reception when scanning objects outside

I changed the "Global" setting with no change. Thanks for the suggestion.

daveo89, please attach your recent configuration so we may review.

Here is the current config that I'm running right now. The conventional channels are working fine. It's just the P-25 channels that won't come in. Thanks for the help.

Daveo89, I see several little things that I wish to point out.

You mentioned that the conventional channels are working however this configuration file contained no conventional frequencies. Were these removed recently?

I noticed you have scanlist 11, 12, 13, and 14 enabled, but your scan set only encompasses scanlists 1 - 10.
With the scanset of 1-10, the unit will ignore objects assigned to scanlists outside the listed scanset even if enabled.

Regarding the Monroe/Ontario Counties P25 system, Monroe South has LCN 4, 5, 6, 7, 8, and 9 locked out.

Regarding the East Site, the Data Threshold Low should be 88 and I see you have this set to 75

I did not see Attenuation applied to the Monroe/Ontario Counties P25 system in question (maybe you just tested this briefly with the ATT button instead)

You also have a Monroe/Ontario Counties Motorola Trunking system without any talkgroups entered. I could not find this system when reviewing the radioreference database. Can you elaborate?

I would recommend that you look over and address the items mentioned above, then we can begin making small changes only to the system in question to see if there is improvement.

I think I sent the wrong file. No! I did send the wrong file. I made some of the changes you suggested and am running the radio. I'm not seeing much difference though. I copied the file from the radio and here it is.

I will review and let you know if I spot anything on the Monroe P25 system.
Give me a bit to run some tests.

btw, I see that your DMR Trunked system LCN frequencies are not grouped together, you may want to correct this as I do not know how the unit will perform on this DMR system with 0.00000 positioned between several of the LCN frequencies.

I'm just happy for you and the other's here taking the time out to try to help me out.

It seems you did not set the Radio ATT to Global and as a result the Attenuation you set to "Global" on your specific P25 system was ignored. This would result in no change which you have confirmed.

For the scanner to respond to individualized Attenuation selections, you must set the scanner to show the letter G along the top line of the LCD. This tells the scanner to apply Attenuation only any individual object that has the Attenuation box checked or to any system that has the Attenuation set to Global.

If setting this using the scanner keyboard, be sure you do not select GA as this will attenuate everything in your configuration regardless of the Attenuation box status.

To cycle thru these settings on the radio, you can press and release the ATT button, otherwise you can use EZ Scan to change the Attenuation Settings of Attenuation Mode from Normal to Global then write the configuration to your scanner.

Do not change the Global Attenuation On/Off selection as this will apply Attenuation to ALL objects and this is not what you want.

I got the Global Att set and reloaded the program in to the radio. I had it running this evening. The "G" is on the top line of the scanner display now but unfortunately, the P-25 stations are still not making it. Thanks again for the help.

daveo89, do not give up we will work the issue.

"G" shows attenuator is in Global mode. Press the ATT button. Display will switch to GA. when global attenuator is on.

I am sure will get some kind of an answer.
