I don't know whether the windows in your apartment face toward a repeater 
you want to use.  Even if they don't, I think you would be better off with 
coax running from your rig to some kind of antenna, whether it is a vertical 
dipole or a ground plane.  This restricts your mobility while operating, but 
would be better than running higher power  directly into a whip antenna 
mounted to the rig.  You really don't want to be too close to the field from 
an antenna being driven with 20 watts or more.  This would be true even if 
your implant's electronics are not affected.  Experimentation will be needed 
to determine the best location for the antenna.  I hope you can come up with 
something that works satisfactorily.

Subject: a question to anyone out there with cochlear implants.





Hi all,



I have a question for those using cochlear implants.



As I will be using my body-worn processors for any ham radio stuff as the
behind-the-ear (BTEs) cause RFI, I would like to know if any of you have had
any experience with transmitting or receiving with higher wattage such as
10, 15, 20, 25, etc when wearing your cochlear implants.



I am working on trying to find ways I can use my 2 meter radio-as the magnet
mount doesn't quite cut it as we have lots of stupid restrictions on
antennas here.



I am using the wouxun radio. KG-UV2D.



I know we have talked about ways and means to get better reception and
transmissions, but I am interested in the effects the extra wattage may have
on the cochlear implants.



Here is a note from an audiologist with advanced bionics with my inqury at
the top of hers.



Dear Barbara,



I am copying this note to Dr. Nancy muscato, my dear audiologist; my husband
Arthur nolden; and our dear friend and amateur radio club president Bill
Pfaff.



I am a ham operator and earlier this year you and I communicated about my
cochlear implants causing RFI (radio frequency interference).



As a result of some of the suggestions the clinical engineers provided, I am
using my Platinum Body Processor and its Platinum Headpiece (PHP)
bilaterally

when at the club since there was no interference on any frequencies with it.
I will also use them at home when using my 2 meter radio.



However, we are trying to figure out a way my radio can get better reception
and transmission power as we live in a condominium complex and there are
restrictions.



My 2 meter ham radio is running on 5 watts output.



We would like to know if increasing the wattage output to 15, 20 or even 25
wats output will cause any effect or Damage to the cochlear implants.



We would truly appreciate any information you or the clinical engineers at
Advanced Bionics Corp can provide in this matter.



Thank you, we look forward to hearing from you.



Sincerely,



Linda



Dear Linda,



The engineers reviewed this and the implant itself has not been tested at
those higher levels of power (watts).  Advanced Bionics implants are
specifically tuned for 49 MHz and 10.7 MHz.  Since these higher wattage
levels have not been tested, any adverse effects on the implant are unknown
but possible (i.e. cannot be ruled out completely). We have not tested the
implant for these specific frequency parameters especially at the power
level specified.







Hugs and 73
