Bob,

1) a) Make an arrangement to unhook all your phones in the house while you 
are operating.
     b)  See if your portable phones have a way to one-touch dial 911, and 
if it can be disabled.  Your RF may (likely is) activating that "feature" 
and dialing for you.

2) Get and read the ARRL book on Radio Frequency Interference.
The ARRL RFI Book -- Practical Cures for Radio Frequency Interference.
(ISBN: 0-87259-683-4) #6834 -- $24.95

3) Order some capacitors and inductors to make up filters/bypass circuits 
as the handbook advises.

4) Install devices as needed.

5) Maybe: get a new set of portable phones.

We have portable phones at our house (2.4 gHz?) and so I'm eager to find 
out what solves your problem (before I go QRO).
