8000 infections per day

When do you breach a certain infection trend, this is a statistical problem and in my opinion you can solve it with the Poisson cumulative distribution. The Poisson distribution is for event probabilities, it is like PDF(x,lambda) where lambda is the average event repetition rate, and where x is a chosen rate. The CDF is the primitive of the PDF, the CDF is used for computing criteria intervals.

Our current rate of infections is 8000 per day, so the problem is, when could you claim a breach in that trend. 8000 on average means that every 10.8 seconds (on average) someone is infected during a day, this is the lambda parameter in the Poisson distribution.

Next you want the CDF of the Poison distribution to be above 90% or below 10% (this choice is arbitrary). For x=6 you will see that CDF_poisson(6,10.8) = 8.7% and for x=15 the CDF_poisson(15,10.8) = 91.77%.

For 1 infection every 6 seconds you find an upper bound of 14400 infections per day and for 1 infection every 15 seconds we get a lower bound of 5760 infections per day. The confidence interval [5760 .. 14400] is pretty wide open.

All discussions where people say, see, it is 500 more (or less) than yesterday are in my opinion therefore meaningless, you need more of a change to get out of the current regime.

Oscar 100 field activity

Did this today, tested a dome for the antenna head.

A basket for tomatoes from the supermarket serves as a dome here. This is a 64cm dish with a duoband feed from DJ7GP

All Oscar 100 stuff is from Kuhne, it works fine

GPS box is from Leo Bodnar, it provides the 10 MHz reference for the up and down converter local oscillators.

Take no compromise on any battery, 60 Ah lifepo4 it shall be (from GWL power)

Storage of cables

You probably have plenty of cables in your shack, and initially you store them in boxes or drawers and it becomes a mess. I think it is better to hang them on a rail, so this is what I made from an aluminium L bar and a jigsaw, and a strip of makerbeam material.

Cable storage system, you can buy them or make them yourself which is probably cheaper.

And it is meant to prevent this, and entangled mess in which you lose what you were looking for.

So this is a storage box for left over wire and cable, but not for cables with connectors on them.
