Hi,
I have made all shematic changes, I put an scope on TR2 and TR3,
I have pulses on them (I use the software written for 16f84a with rb4, rb5, rb5 –load defaults, rb7 enable/disable rx,tx., if I recompile- pop up bank selected bits warning but I think is ok ?) , I can modify pulse width, I set VR2 at 9V at pin6 (output of IC4), try change 4066 switch, but output tone don’t increase near metals.
any ideas ….. I have to shield the coil???
Thanks in advance
