Hi Marco, another tip from Jon was that around the operator shift-change
time (about 2300z) the mod will usually be killed and the two extreme shift
frequencies applied just long enough for the oncomming operators to read a
frequency counter, before the mod is returned. I have seen this happen at
around 2315z but as early as 2250z
