Low Microwave Band RX - Minimal Working Example

As seen in RadCom GHz Column, March 2023.

Using cheap ADF4351 for LO on 1888 MHz;

homemade (yes that’s tinfoil and garden wire!) bi-quad;

mixer I got as junk at the Roundtable and an SDR dongle.

Not going to win a DX award but on the waterfall is GB3ZME 25 miles away from the antenna on the bench.
