Franco's LRL ver_4046

[enjoykin4]

Hello Mr. Geo

Thank you for your pcb layout.

I think the only thing who will happend when you put LRL in shielded box will be the shielding of transversal EM waves and noise.

If you touch antenna and LRL boost signals (make beeps) - he is working in reverse mode.

About spurious oscillations i think they were related to noise caused by environmental noise.
Franco PLL-LRL is very sensitive to presence of human body near L1-C11-C10-C9-C8-Tr2.

If you find again oscillations try to lower 150k resistor from base of Tr1 to ground at 47K-68K.
