First question would be to please describe your grounding system. Coax,
computer, electric service, phone, etc. Phil KB9CRY

> 2. One PC monitor now displays purple around the edges and green in the

> 3. Alpha 87A will not turn on. Checked and found no voltage at power
> outlet. Found breaker in service panel tripped. Reset breaker, have 230VAC
> at outlet, still will not turn on. Need to check amp fuse.
>
> 4. Phone inoperative. Called for service. They detect problem on line
> outside house.
>
> 5. Satellite TV to shack inoperative. Tried receiver reset, no luck.
> Satellite works fine in main house.

> This is sort of a mystery to me. But here is my analysis:
>
> The shack is a 1000 sq ft "apartment" about 50 feet from the main house. It
> has den, kitchen, bedroom, bath, laundry, etc. It has its own power service
> and meter. There is a conduit running between the house and shack that
> carries prone line, LAN cable and TV cable. It enters the shack through the
> same area used for AC power meter and breaker box. I am guessing that these
> cables picked up a rather large EMP from the strike.
>
> I would like opinions from the list. Thanks.
