Intermodulation Problems
Your WiNRADiO receiver has been designed to be very sensitive in order for it to work
with the moderately small antennas which are preferable for VHF/UHF. In areas with strong
local broadcast stations, the WiNRADiO receiver front-end may overload and, as a result,
intermodulation products may appear in the received band. By pressing the Local button on
the control panel, the interference products will disappear.
It is advisable to use the Local setting if you are operating the receiver with larger outdoor
antennas, especially on broadcast bands. For long-distance shortwave reception, a
considerable improvement can be obtained by using a tuned antenna and preselector.
