[Solved] Attiny85 Transmit rf 433


i have been testing few libraries and i came thru rcswitch. I am able to transmit on pin PB3 which is physical pin 2 but not when connecting the transmitter on PB2 which is physical pin 7.
Do only specific pins have the ability to transmit data or i am missing something?

Solved: When programming with Arduino as ISP you need to disconnect the wire going from Arduino to PB2 of Attiny85!
