•About operating frequencies and spurious signals
When received frequencies are as shown below, there may be cases
when you receive non-modulated carriers. This is due to the frequency
composition of the product and not due to a malfunction.
Main side frequency· 51.65MHz = Sub side frequency· (50.75 X 2) MHz
Main side frequency - (51.65 x 2) MHz= Sub side frequency+ 50.75MHz
Main side frequency - (51.65 x 2) MHz= Sub side frequency- 50.75MHz
(222MHz bandwidth - 51.65MHz) x integral multiple= 222MHz bandwidth frequencies
(222MHz bandwidth - 51.65MHz) x integral multiple = 902MHz bandwidth frequencies
(902MHz bandwidth - 51.65MHz) x integral multiple= 902MHz bandwidth frequencies
When the received frequency is approximately 3 times the transmitted
frequency, it causes signal suppression.
When receiving simultaneously, if the sub band's VCO frequency is near
the main band's IF frequency, the indicated frequency causes reception
suppression.

There are many business radio. stations operating in proximity to the ham bands.
Be
careful not to cause interference when transmitting around such radio stations. Even
when amateur radio stations adhere to radio laws, there are unexpected cases of radio
interference. When operating this product while traveling, please be very careful.
