FM Radio why no station at 96.0khz?

I have tried this, still no signal for BBC Radio 4

Wikipedia says that in Northern Ireland (where I live) BBC Radio 4 is broadcast at 125 power whereas all the other BBC channels are 250 power…not sure what the measurement is!!, but that might expain it. Radio 4 is not as strong a signal, and the radio in this unit is just not strong enough to pick up thatsignal. Interesting though that a Poundland radio can pick it up… I think I’ll return this and buy a different one. Thanks for your help
