help,wireless camera and receiver
 

I have a wireless Camera with a Tv receiver,, it is the Remington,,
brand name,,,,, i know it works in the 900 mhz range,, the tv has a
switch for channel 1 or channel 2 or for autoscan in case you have 2
cameras to scan,,,, the tv also has a fine tuneing dial,,,
is it possible to modify this Tv so it can maybe pick up another cameras
channel or possibly the Amateur Tv repeaters?
this wireless cam and rec are in black and white and for security,,,
thanks for any information,
best regards Kringles,
