Howard, regarding your first question about the wireless 
headphones, you may be able to find the signal on the 71a, but 
the headset transmitters are most likely wideband whereas  the 
71a can only receive narrow band FM far as I know.  So if you are 
able to hear the output from the headset transmitter, sances are, 
it will sound pretty garbled unless the audio coming through it 
happens to be very quiet at the time you are listening.  I wish I 
had one of those so I could experiment.  Only thing I have close 
to that is a Yaesu Vr500 pocket receiver that goes from 150 KHZ 
to 1.3 GHZ and does have a wideband Fm mode.  I have heard 
wireless mics at places where I have played gigs, like a swing 
dance club where the instructors wore the mic to give verbal 
commands to the people.  They came through fine but were fairly 
quiet audio over the VR500 and the range was not much.  But then 
that little receiver has  questionable sensitivity especially up 
in the 600 meg range where those mic's were.  Jim WA6EKS

Subject: two unrelated questions

1.  I have a tmv-7100A, and a number of 900 mhz wireless 
headsets, I would
like to listen to the transmitters on the 7100.  I adjusted the 
step size to
5 KHZ, and tuned the 900 to 1000 mhz space.
No signals, I don't know if they will be to broad to decode, but 
does
anybody know where those things really transmit?

2.  I am listening to the French Open on tune in radio, just went 
to their
link, but it looks like this site should be very usable, am I 
right?  What
are people's experiences with it from the PC, not from the ap?
