| 217760 | 2004-02-24 03:20:00 | Since getting Jetstream the quality of sound on my cordless phone has gone down the drain. I now can hardly hear anyone I'm talking to, and it's a pain as I've had to revert back to my corded phone. Has anyone had the same sort of issues, or know any sort of resolution? Heres what I know: - The phone is a Panasonic KX-TC1045 - I use 3 filters in the house - I have been told that a splitter may not solve the problem - Turning the router off does not fix the problem |

| 217761 | 2004-02-24 03:29:00 | Some cordless phones have a low frequency transmitter back to the base, or from the base to the phone. These can be badly affected by the Jetstream signal, which is radiated from the phone lines to a small degree, and could easily disrupt the phone signal for the whole house. Jetstream is carried as a "radio" type signal along the phone line between 1 and 2 MHz in frequency at the upper end. This is probably whats causing your phone problems, and no amount of filtering will help, only physical separation of the phone and the handset from the incoming phone line. Thats not a practical proposition. Best solution is to get another phone, but avoid the low frequency ones. Use a DECT system or a 2.4 GHz band phone. |

| 217762 | 2004-02-24 03:36:00 | Now thats a new thought that neither Telcom nor Panasonic have told me. Something well worth considering I bet. Anything thing I've been thinking about, is that the phone is kind of old, so the battery life isn't the greatest anymore, and it does get quite heavy usage. Would a new battery help at all? Because I believe that some nights the volume is higher than others. |

| 217763 | 2004-02-24 03:36:00 | It seems that that phone uses 30-39MHz, so the ADSL frequencies shouldn't affect it. Of course, "shouldn't" doesn't necessarily mean "won't". In fact, the ADSL is digital, so it will have lots of harmonics. :D If you have a look at what Google gives for "cordless phone problem adsl" you'll see that others have this problem. In fact, it's suggested that Panasonic cordless phones can cause problems to the ADSL link too. ;-) A 2.4GHz cordless would probably be better. Guess what will happen if you use Bluetooth or WiFi. :_| |

| 217764 | 2004-02-24 03:42:00 | So exactly what is the advantage of these 2.4GHz phones? (sorry, I'm useless at these kind of things) I assume that something like this: Uniden 2.4GHz phone (www.dse.co.nz) Would that do the trick? |

| 217765 | 2004-02-24 03:43:00 | Some of the 38 MHz phones used a 1.75 MHz local link in a duplex method, presumably for separation without the need for sharp filters. They don't seem to tell you that on the data for the phones. This is what I refer to, and I have heard the problem many times. And no, a new battery will not help at all if this is the cause. |

| 217767 | 2004-02-24 03:55:00 | Thanks for that guys.. I might just give that Uniden phone I mentioned above a go. From what I understand, it'll operate at a frequency much higher than Jet stream and cause less interference making my volume increase so that I can actually hear other people on the line. |

| 217768 | 2004-02-24 03:57:00 | > So exactly what is the advantage of these 2.4GHz > phones? Yes, that would do the trick, however I wouldn't have a Uniden phone myself. You get exactly what you pay for. Thats a cheap price... These (www.dse.co.nz ) are very good however ... not a cheap price.... As stated, the ADSL Jetstream signal radiates in the 1 - 2 MHz band (and up to several MHZ through harmonics). The 2.4 GHz phones use a frequency of 2,400 MHz. Its a long way from the interference frequency, which is the whole objective. 900 MHz (0.9 GHz) phones are also a long way away, and work fine as do 1.8 GHz models. Many 30 - 40 MHz phones work OK, and what works is not a problem. Just dont risk another low frequency one. DSE is safe, as you can always take it back. |
