My kitchen phone was crackling horribly, so I bought a replacement
at Radio Shack. It worked fine for a month or so, then IT started
crackling just a week ago!

The phone AND the personal alarm system (in case of accident press
pendant around neck and summon help) both plug into the wall jack. I
unplugged the alarm and plugged in only the phone. Still crackled.

I plugged the phone into a jack in another room, where it worked
fine. So is the problem in the jack? Or where?
All other phones in house work OK.

If only I had inside wiring coverage, I'd be home free, but I
cancelled it a while back because it had become so expensive.

After looking in vain on-line for a diagram or something to help me
decide whether I can fix this,
I appeal to Your Greater Minds.

Is this something an amateur should be able to do?

Can someone offer succinct directions, or...

....refer me to a Web site for directions?

TIA
