I think the diode at the input is backwards, if the connector P1 is the power supply plug connector.
I built one from your schematic and it seems to work ok, the led is blinking. Now just need to test it on my decoder loop and see if it picks up. This is on the transponder schematic.
Investigate if following code can generate a 4mhz clock and if it works to program a attiny with external clock bit set.

//ICR minimum 2 F = 16000000MHz No Change if using 14.7456MHz very close for fucking lazy bitch. and I don't need precision PWM at all.
16.MHz Xtal for PWM Frequency while 14.7456MHz for Precision Baudrate RS232/RS485/RS422
/*make this variable as table.
