[comp.dcom.telecom] Looking For Frequencies Used By Cordless Phones

hoekstra@uunet.uu.net (John Hoekstra) (04/12/90)

Someone posted a little while ago the ten frequencies assigned to
cordless phones.  I thought that I saved that article but I apparently
failed to do so.  Could that person repost those frequencies again?
Mucho appreciated.

What are the optimal channels for cordless phones?

I just bought an AT&T 5200 cordless phone which uses channels seven
and nine.  When using channel seven I get an occasional buzzing hum
but I do not get that hum when using channel nine.  I first thought
the cause was our Fisher Price baby monitor which uses channels A and
D (I have no idea what the correlation of A and D have to the ten
channels that the FCC allocates).  The buzzing hum occurs for channel
seven regardless if the baby monitor is set to channel A or D or if
the baby monitor is turned off.  This eliminates our baby monitor as
the cause or so it seems.  This leads to some questions:

1. Does anyone have a good explanation to why channel seven may be
experiencing that buzzing hum?

2. Are there some of the ten channels that can be considered more
optimal than others?  The Phone Center that I went to only offered
phones that consisted of either the channels seven and nine
combination or the channels six and eight combination.  Not much of a
choice.  I still would like to know because I can always go to another
Phone Center store.

3. Does anyone know what frequency channels A and D use for the Fisher
Price monitors?

Any information would be greatly appreciated.  Thanks in advance.
