- Last weekend, we moved into a new home close by a local radio station. I
- had expected RFI to degrade our television reception, but I was aghast to
- discover that it is affecting our phones as well. The phone lines are
- quite noisy, and if you listen you can clearly make out the voices and
- music of the radio station's broadcast. Some times are worse than others.
- The phone company says there is nothing it can do.
-
- Needless to say, this is having a bad effect on my modem communications.
- It is hard to establish connections, and several times I have lost
- connection in mid session. Text scrolls across the screen in fits and
- starts as data is transmitted and retransmitted through the line noise.
- Several file transfers have bombed out.
-
- I suppose dropping my baud rate will help (ugh!), but is there anything
- else I can try? Specifically:
-
- --hardware fixes? (filters and other gizmos)
- --modem settings? (I have an Intel 2400B MNP modem)
- --telecommunications software?
- --file transfer protocols especially effective dealing with line noise
- and allowing resumption of failed transfers?
-
- Some additional information: We have moved into the first floor of an
- older two-flat. The modem, an Intel 2400B MNP, hooks up via regular
- twisted-pair cable, about six feet in length, to a modular phone jack.
- The computer equipment is properly grounded.
-
- The situation is not so bad that I can't read news, answer e-mail,
- etc. (although sometimes even these activities are iffy), but I expect
- downloading may well be effectively impossible. Can anyone offer any
- advice? (Other than moving again or just forgetting the whole thing,
- I mean.)
