Sure. Are you sure you can't hook your UHF board up to a basic tx or rx at least for prototyping? What's your gadget's IF? ** In fact what I need is to convert 2 CW coherent signals (beacon)IF in UHF range (somewhere between 0.5 to 1GHz , through a very goo

Hello, I would like to develop a user card, to interface with the USRP motherboard, with a high resolution UHF synthesized local oscillator for a flexible narrowband application that can not use any standard card. Is this possible? Can I program the I2C/SPI chips through GNU radio? (The on card RO
