Thanks Todd, The newest version is sounding great. I have the V version with the MCU set to 480MHZ on 700 and 800 MHZ
P25RX Firmware Updates / Testing

This was what I meant but poorly wrote in my earlier message - should have wrote "channel filters" rather than IF. But I also got it "backwards" in that I was thinking in terms of the filters' BW's not being setup right due to the slower clock speed rather than your more obvious likelyhood that the sampling for a wider filter throughput taxes the MCU more.
For what it's worth, here is how I have mine currently set:
And, so far, seems ok. I did hear a little "stutter" on one P2 piece of traffic but that was from the infamous school bus dispatcher who (along with the drivers themselves it must be admitted) don't really have the best "radio etiquette" as I've mentioned in the past. They tend to yell into their mics when the other party asks for a repeat.

I'm currently testing 15.6 kHz with some more changes to delays. It could be my imagination, but I think version 2021-07-15_1231 may sound
better. It certainly sounds good here. DMR also sounds good. DMR currently uses a fixed setting of 14.2 kHz.

I am running newest, at 480, filters both on 14.2... moving from 700mhz site to the 800mhz site when I get home, both signals similar 3 bars.
I'm going to test both my P25RX units with the latest firmware and report back the results to you later this evening. Will test P2 at both 400 and 480 Mhz mcu speed and let you know my results.
Thank you!
Thank you for testing!
I went to test the 7-15 firmware and it "bricked" my first P25RX when the firmware process completed.
I've powered off the P25RX and re-ran BTConfig but it just hangs at "read sys_config".
I tried flashing back to previous stable firmware but it won't flash back -- the BTConfig software always hangs at "read sys_config" and does not give me a prompt to update firmware.
UPDATE -- Had to hold the Talkgroup button for 10 seconds when powering the P25RX up and was able to flash back to the last stable version of BTConfig (6-17-2021) and the P25RX now works normally, but trying to flash to the latest TEST version (BTConfig-2021-07-15_1231) will consistently brick my P25RX -- I've tried it 4 times and each time the firmware always flashes successfully and the P25RX resets but always hangs after the 7-15 firmware was applied at "read sys_config". Please note this firmware update is being done on a Mac, but I've never had issues before when flashing firmware using the Mac. I will try flashing the BTConfig 7-15 firmware tomorrow using a PC to see if I get different results

Thank you for testing. I'm not sure at this point what might cause this. There is quite a bit of complexity to all the internal clocks. I may have overlooked something. Can you use the 'mcu_ver' command on the earlier firmware to report what version of the MCU you have on this receiver?
I think I found the cause. Can you give 2021-07-16_0301 a try?
I am running 7-15:0301 at 480 on a V version and working fine on P1 and P2 now for several hours.
Question for you Todd, if you have a V version what MHZ should you run and if you have the Y version what MHZ should you run
The way I understand it is that the "V" version is spec'd to 480 MHz BUT the newer parts that are now available for Todd to build new units going forward are the "Y" versions and are only spec'd to 400 MHz. Therefor, Todd is now trying to optimize his new code to work properly with the lower frequency MCU's so he wants us to test as much as possible at 400 MHz even if we have a "V" version that can do 480 MHz.
Basically, 400 MHz is "the new norm" so Todd has to make sure everything works well at that lower clock speed.
If you have a "V" version you can use 480 MHz but understand that, going forward, 400 MHz will be the default for newer units as well as future firmware and software.

Thanks Mike!

I havent been able to test any of the newer releases, but, i did have the same issue as @Cheeseburgers on the same system that he was using it on. Running my V unit at 400 gave me choppy audio like he reported. I had switched it in the software to 480, but didnt restart the unit and software so i guess the change never went through. I will try tonight and then i will also try the newest release, but just so you know it isnt a one-off instance, i am also hang the same issue on the same system, although mine is monitoring a different site.
