Improving the Tracker IV

[Adam24]

I drew up part of the Tracker IV schematic a while ago (the rest was difficult unless you remove
all the components). The resistors were verified by reading the values but caps were measured
in circuit so may be wrong values on schematic.

The circuit looks a bit different than most here and some tricky things are done when switching
modes. (Removing grounds from chips and such).

Mine only goes 2 - 2.5" (50 - 65mm) deep so I was looking for some improvements to gain a bit
more depth. The RX seems to be tuned to 32.5 khz where the TX is 6.5 khz seems a bit funny
maybe tuned to a harmonic?

I thought I might try winding a new coil and maybe messing with the TX (though that's tough
without the complete schematic. Maybe just tuning the RX cap would gain something? I tweaked
the VR1 pot and gained 1/2" or so but it probably messed up the disc.

I'm going to test some baseline targets today then try winding some coils to see what I can do.[ATTACH]29350[/ATTACH]

Hello silver, this is Adam fro Egypt.
Did you draw this schematic or downloaded it. Is it a functional one.
