hello
I have a question about Sceatta 3.4
1-I read a suggestion about replacing 7805 by 7808 to get more sens is it a good Idea?
2-is it true that both coils TX and RX are made with 6 mh of inductance why ther is no difference betwin them specially the detector loks like TGSL with few changes about RX omp Lm301 instead of LF353?
3-what are these signals and why they are 180° of phase difference ?whay not the Rx signal lagging the TX signal by 20°

Not familiar with that circuit.  Sounds like someones work in progress to me.  Without knowing what points the screen shot came from they are Meaningless.
