Kirisun PT617A VHF Mobile Radio Inside Pictures

Some pictures of the inside of the Kirisun PT617A i'm hoping to get working. Mic and cable still on the way!

The massive heatsink on the back extends into the radio and covers most of the top of the board. Looks like it will take some juice when transmitting for a sink that size.



The circuit board inside is pretty simple, nothing like the older radios. Microcontroller is visible to the left and the baseband processor in the middle and I have no idea what anything else is!

 

RA30H1317M is a 30 watt RF MOSFET Amplifier Module commonly used on these sort of radios that operate in the 135 to175 MHz range. 


On the top of the radio is the tiny speaker and some other bits and peices. The speaker just sits on a foam spacer and is not fixed in place.


 

Lastly is the front face, nothing really to note on there. The volume control is on the left of the photo, the mic socket is on the right. Note the picture is upside down.


Hope someone finds it interesting! Just hope I can get it running this week.

Thanks for reading!
