Using other receiver front ends with a tayloe mixer #76

Can I and Q outputs of any receiver frontend using a Tayloe mixer be applied to the RSP pico for which you have prepared the software? For example, If the LO_I and LO_Q signals are applied directly to the FST3253, can the I and Q signals produced by the receiver module produced by QRP-Labs be applied to the PICO?

Yes, that's exactly how I built the first prototype! You can just about see it in this video. You just need to bias the I and Q signals so that they sit in the centre of the ADC supply rail (about 1.5v).
