Extra test transmission on Tuesday 10th January
The transmission was successful. Reports from Italy indicated good audibility. SAQ was detected by the WWLL receivers in Boston and Nanjing.

The problem with SAQ on Christmas Eve
The reason for the trouble with SAQ on Chrismas Eve was most probably a damaged fuse in the excitation circuit for the 500 V DC generator. The fuse was not completely blown but measured a very high resistance (150 ohm). When we lost the excitation current to the DC generator, we also lost the control current to the choke coils in the conductors to the main motor, and thereby the speed control of the alternator was lost.
It was confusing that the problem occured exactly when we connected the running alternator to the antenna. We were actually on air a few seconds with decreasing frequency until the antenna was disconnected by the protection circuit in the speed control.

Unofficial transmissions
Unofficial transmissions may take place, due to maintenance, training or local events. Reports from unofficial transmissions are normally not confirmed by QSL cards.

Start of alternator without transmission
In summertime, the Alexander Society shows the alternator on Tuesday evenings, combined with a start of the alternator. On these events, there is no transmission from SAQ,
