The damage by a tyhoon,
and storong wind,
and other.

The antenna which was broken by a strong wind by a typhoon in '93. There is not a method to detach except that I cut it off when it grows in this way. We changed an antenna for big special order product of pair wind velocity afterwards, but a tower was broken in a typhoon of 96 and did it to a crank up tower currently.

7MHz3element Yagi antena which was broken in a typhoon of '95. We turned it into a high product of pair wind velocity (special order product), but the wind of the summit of a mountain was more than imagination. A tower collapsed at last in 96 and installed crank up. It is terrible if I become such a state in a residential area.

The JR6CKY(left) and the JR6HVE(right) where the mast which I cut has clamping it Included weight, was thick, iron, clamping it turned. It is power of terrible wind.

We installed 3.8 rotaryDP, and a gear of rotater was damaged with a torque. We use terrible labor for repair of rotater when we installed a large-sized antenna.

A linear amplifier heater terminal of Henry has become contact defectiveness.　 Because it is the place that Daiden style flows through, only contact resistance causes a big obstacle. It processed a copper sheet and improved connection to a certain thing.

A linear amplifier of Dentron which used purchased it, and tried it hard. A plate ammeter has finished wagging it during contests suddenly. Smoke appeared in an instant! Rare shortstop of high pressure trans. We gave a damage to trans diodes to rectify, but revived because, fortunately, an equal trans was available.

We think that SWR is high how recently and adjusted it, but a … cause is balun. Because I become resist pressure 3KV, I felt relieved, but it will be impossible a high resist pressure in enamel coating it is over, and to be surprised at. A symptom to be similar in a certain university club was reported in a home page. I expect manufacturer improvement.

When I looked for instructions. I discover a nest of a customer "field mouse" most unpleasant. It is from a small gap, and a field mouse invades it. It was bitten a cable and encountered terrible judgment formerly. Because there is worry of a mite, it is necessary to block up a hole surely after having done cable construction.
