Hi Steve, It's a long shot but its possible your PC may be having linux USB issues... I have had major problems with some intel motherboards using the onboard USB with linux.To check, get a cheap USB 2.0 pci card and try that in the PC with the uri plugged into the card. Even changing to another USB port on the same motherboard can help! Run the dmesg command and look for any USB error messages. If dmesg has no errors and your Allstar config is ok, then try a cheap USB 2.0 pci card Regards Anthony, VK2ACP
absolutely. the onboard usb is probably the afterthought, meant for keyboard and mouse and not much else...try an add on card, version 2 usb...you will probably find it works a heck of a lot better...it did for me. -- Bryan Sent from my iPhone 5...small keyboard, big fingers...please forgive misspellings...

Figured I'd throw this out... I'm interfacing a batwing Systel repeater for 440...basically 2 GP300 HTs stripped out of their cases, mounted on a headsink in a box with interface circuits (which I'm not using, lifted the necessary signal resistors so that the signals don't use the onboard controller, etc)...well, gone through the schematic, and have the proper pickoff for rx, can get it to recognize (using the PL detect pin going high +5v to give me a COR), asterisk recognizes carrier (faking it out by using the PL detect), keys up the xmt side...however, no matter HOW high I set the audio into the transmitter in radio-tune-menu, it is barely deviating. Now, I can take an audio generator from my streaming studio, and, injecting a 1K @+4dBm tone, I can get non-distorted deviation at 3.2K by hanging on the tx input pin. So..wondering what the audio level out of the URI is? I'm thinking it's lower level then that, maybe -10?. And based on the low level deviation...I'm thinking that even the +6dB amp onboard won't do much... I know that RB had to build an amp to get enough drive to modulate the 220 Micor using direct FM injection when they built my rig; does anyone have a simple schematic of a 5534 or some such op-amp that can give me a reasonable amount of gain so I can try and get decent (well, how about understandable) deviation out of this thing? Thanks, all. BB
The uri can put out up t o1 V p-p. so it should be enough. Are you connected to an out put on the URI that has a cap in line? The mic circuits might have some dc bias that is fighting with the URI. So put a cap in line and see if you get tx audio. Dont know which pin you are using but I m using tx audio in the 20 ish range on the URI. Cant remember which but it has a cap in line.

using the ac coupled line, not the direct...iirc it has a 10 uf @16v from the schematic. -- Bryan Sent from my iPhone 5...small keyboard, big fingers...please forgive misspellings... On May 18, 2013, at 21:42, RED BUTTON MICRO <jrorke@cogeco.ca> wrote:
