My SPM12 has a phased locked loop, with coarse and fine tuning as well as the main tuning dial, maybe there are various specifications for the same models. It has a 10 khz IF output plus other outputs. I built a product det and the whole unit works well and is very sensitive and selective down to 25 hz. I also use an ext DSP unit. The whole package makes a great LF receiver and works well also with my receiving loop antenna. 73 de Mal/G3KEV
