signal level good enough for a URI-X?
Anyone can confirm if a signal level of 70~90mVrms with an Output impedance: 1kΩ or less Coupling: AC coupling Frequency response: ±2.5dB at 10~3000Hz is enough to drive a URI or should I use the included pre amp in the URI-X? trying to use the RD line from a tkr-750 to do USBRadio control of a node. thanks And while I am at it, pin 10 and 11 of the tkr both are signal input, 10 is TD (tx data) and 11 is TA (tx audio) If I feed one side of the output to the pin 10 (TD) for tone signal and the other side to (TA) and apply repeated audio would that make sens? Cause I did try that and It did not seem to work.. thanks again for your input Pierre VE2PF

<-- Hi Pierre: A picture is worth a thousand words..... you have my schematic for my dual mode (DV / FM) MUX, which shows the exact pin-out for the DB25 on the TKR 750/850. So there you go - now you have a schematic and a few words :) Bon Chance! Salut, Ramesh.
Do you use tone for the audio? is ot controled by app_rpt or the repeater itself? I dont think it would be the repeater, cause it would interfere witht the dstar protion of the system.. Did you do something else then just that hardware? did you had to change a lot of setting inside the repeater? lots of question, cause I did took a look at the shematic before, and was not able to set the audio level with usbradio..

Short answer is yes. RD line is discriminator so you would need to set the USBradio file to Flat audio. The rolloff of this output may not be enough for the DSP decoding for DSP Carrier squelch. It needs to see more raw audio above 3khz. So you may need to use the hardware COR lines from the repeater. If the audio level is too low, at this input then you can set RX boost = yes in the USBradio file and do a re-cal to see if you get it to work properly. You should not need to use a hardware amp in the URI. As for the Pins 10 and 11, They are not inputs but are out puts from the Kenwwod. Pin 10 is discriminator and pin 11 is RX audio and is de-emphasized. There may be more audio from Pin 11 and if you use this pin then set audio to Speaker in USBRadio. Pins 8 and 9 are TX audio inputs to the kenwood. Pin 8 is the TD input. This input is a "direct mod" input and is good from dc to 3K. it is mainly used for an External Pl tone or 1200 baud data input. NOTE: this input will only allow up to 2.5 Khz deviation no matter how hard you drive it. Ths is fixed in the Kenwood. Pin 9 is the TA input and can take analog audio from 300 hz to 3k but has pre-emphasis. So if you are connecting a URI to teh Kenwood, see the pinouts below.. TKR 850 -------- URI 8 (TD) --------- 23 (R_out) 9 (TA) --------- 22 (L_out) 10 (RD)-------- 21 (Mic in) 16 (EPTT)-------1 (PTT) 17 (SC) --------- 8 (Cor in) 12 (RXG) ------19 (Gnd) 19 (TXG) ------ 20 (Gnd) You may need to add the extra audio grounds RXG and TXG.

trying to use the RD line from a tkr-750 to do USBRadio control of a node.
thanks
And while I am at it,
pin 10 and 11 of the tkr both are signal input, 10 is TD (tx data) and 11 is TA (tx audio) If I feed one side of the output to the pin 10 (TD) for tone signal and the other side to (TA) and apply repeated audio would that make sens?
Cause I did try that and It did not seem to work..
thanks again for your input

Wow a big thank you. was not hoping for such detail information.. I will work with that.. Looklike I was reading some info bad from the service manual or I do need more then 4 hours of sleep a day.. (need to leave some activity out.. cant wait to hit 55 and start on a real job I like ;-) ) big thank you Jon.
