BONJOUR!
The TDA7000 "radio" IC and the BC109 transistor are obsolete and are not made anymore.
The TDA7000 had horrible performance. I used BC109 transistors in my first job 45 years ago.
The hFE of an old BC109 is not 300, it is a range from 200 to 800. Yours might be 300.
Its Vbe is not 0.7V, with a collector current as low as 0.5mA then its Vbe is about 0.6V.
Good FM radio ICs are very complicated. The TDA7513 has 80 pins in a tiny surface-mount package and has many features that are programmed and set by a microcontroller. It is used in modern car radios and home stereos.
The old TDA7000 IC was replaced by the TDA7088 IC that is copied by Chinese semiconductor manufacturers. The FM radio scans to a station (and frequently misses) and costs only $1.00 at The Dollar Store. I have two of these radios and the performance and sound are awful.
Philips and Sony had FM radio ICs that used a normal but cheap FM circuit. They were used in cheap clock radios and I have one in a portable Sony Walkman FM stereo radio. They are not made anymore.
I don't know which Chinese radio IC is used in modern clock radios but their performance is not good.
