HF QRM Filter

C1,C2,C3 = 4700pF, 1000V
L1 = dual wire, as much as you can. HF ferrite ring.

Also:
1) 12V power line, ferrite bead
2) HF Antenna cable, ferrite ring
3) Audio cable, ferrite

More ferrites = Better life (笑)

ネットワークのトラブル

今日のmorningのすべてのネットワークがダウンした.
APC UPS is burned out...

It's a very big problem of Russia at all, that merchants ask manufacturer (China) to made device more cheaper, and manufacturer made cheaper, whithout some useful parts.
Today morning i comes to workplace and see: なんじゃこりゃ〜！Strong smell of　「resistances and wires」goes from サーバールーム...
早く早くswitch off burned UPS, reconnect main hubs to another, and problem was solved...

P.S.: Look at this page address... i win a lotery? ^ ^; 「21555555.html」
