tnx/tvi??Transmitting from hotel bedrooms.
 

but surprized nobody touched the TVI issue , so of the few
suggestions made here, any idea which is , isn't the best for
avoiding tvi and any tips on how i can minimize tvi

Hi, I would think the reason no one touched on the TVI issue, is that it is
almost unavoidable. TVI is caused by RF getting in the TV antenna terminals
and causing overload of the TV front end, or rf getting into the AC power cable
feeding the TV.
What you are attempting is to produce enough RF energy for communications,
but not enough to cause TVI. The first thing I would try is reduce transmitter
power to a point where the TVI is not there. Communications probably won't be
there either. Low power CW would be the best mode. Least TVI, best chance of
being heard.
Get the antenna as far away from the TV and building wiring as possible.
Outside the building would be best. Make sure only the antenna radiates, not
the transmission line. Use a choke balun on the transmission line. Some TVI
filters on the TV might help, but if your antenna is inside the building you
will probably get into the TV distribution system. This will insure that you
are messing up every TV in the Hotel.
Every time I have tried to operate with the antenna inside the room, I have
experienced TVI. Usually it's not that bad even at 100 watts, but it is still
there even with 10 watts. My solution was not to worry about TVI cause I did
not transmit that much. With the antenna in the room, performance was so poor
I couldn't hear anyone to talk to.
