* Si5153
* Check desired frequencies can be achieved:
- * LO1 = 28 - 4.9152 + VFO
- * BFO = 4.91521
- * VHF-LO = 144 + 28 and 144 - 28
+ * clk0: LO1 = 28 - 4.9152 + VFO
+ * clk1: VHF-LO = 144 + 28 and 144 - 28
+ * clk2: BFO = 4.91521
+ * See `freqplan.py`
+ * If not, generate LO1 and BFO with Si5153, and connect an external LO to the VHF LO u.FL
+ * No 116MHz crystals on mouser, but 114.285MHz are available, HF bandpass filters recalculated.
