[App_rpt-users] Resistor divider

[Bryan D. Boyle]

or +2.2 dBm (referenced against 600 ohms).

For what it's worth, radio station consoles work normally (at least in all the plants I built or worked in...) at +4 dBm.  there is MORE than enough level and adjustability without having to pad, attenuate, or go through gyrations to get this to work. I've interfaced everything from aforesaid consoles to cheap chinese HTs to commercial iron thru URIs with nothing other than wire and connectors to mate the equipment.

If it seems its overdriving the URI then disable the RX boost (RXboost=0) in the USBradio.conf file. Then retune.

I do not have this radio so I have no idea what the resistor values would be or if you even need them but I can say you don't want to load that point down so you wouldn't want the total resistance to be too low. The upper resistor (closest to the pot) should be the larger value and the one to ground the lower.
