 * 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.
