Yea, I only see one controller - which cpu do you have? Meanwhile, I'm checking my gaming PC which is an Intel i7-12th gen to see have many controllers it reports.

SDRTrunk Issue with SDRTrunk P25 audio

13th Gen Intel(R) Core(TM) i7-13700F
Yea, it seems that the Intel chipsets (your Z690 and my B760) only have one integral USB controller, whereas my AMD X570 that I use for SDRT has four USB controllers integrated into the chipset. A solution for you is to buy a PCI USB controller card - I believe they make models that have one, two or four USB controllers. Be careful when you buy because the sales lit can be misleading.
Alright, gotcha. Thank you for looking into that. Is there any way to be sure that the lack of other USB controllers is the cause of the issue?
It's almost certainly is a USB bandwidth issue (controllers have a limited amount when locked to a USB 2.0 device), but you can check general system resource usage with Task Manager. I doubt you are having system memory or CPU usage issues. If the system that you are monitoring is in a single band, then I would suggest an Airspy R2 - it can usually cover an entire 800 MHz system by itself and uses only one USB 2.0 port. Same with a 700 MHz system - but not at the same time. If you want to be sure.... you'll have to experiment with what the equipment you have - PCs are unique wrt how they are equipped and configured.
What you can do is experiment with any USB settings that you have in the BIOS. Perhaps there is a setting specific to your motherboard that *could* help - certainly a step before spending money.
I reached out to the computer manufacturer last night to see what they had to say. The guy said that the board they put into the computer only has 1 controller but is robust and can handle high bandwith. I told him it would be 4 SDRs and he said that seems like a lot but doesn't know if it would be an issue. I'll keep them plugged directly into the computer and see if it becomes bearable.
If it continues I'll dish some money into a PCI USB controller or whatever it is called. If anyone has any reccomendations please share. Looking for a cheap and easy to use one.

OC the manufacturer would defend their design strategy. I was thinking about this last night, and it seems that there might be a way to configure each physical port to use a specific PCI lane / allocate bandwidth IF the extensible spec allows it (I think it does); IF Microsoft implements the capability in their driver; IF the mobo manufacturer / model supports it via hw design and bios; and IF the device manufacturer provides a driver that can access those features. Good luck.
Yeah not even going to try all that... way above what I would know how to do without an in depth guide
To update and share my resolution:
I ended up purchasing a Raspberry Pi 5 kit with 8gb of RAM to host my own "feed" of the system. That is just for me right now since BCFY is well covered but I'll consider feeding if the current ones go down.
I also purchased this yagi with some extension cable. I am using the Anker USB hub that I mentioned to plug my 4 SDRs in. It took some location tweaking, but propping it near a window pointing towards the tower is working great. No issues that I have experienced before. Only complaint is the audio sounds muffled or has a lot of background noise compared to a Trunk Recorder feed, but that seems like an SDRTrunk standard.
