HI

I could get Cntroller's Code from ICs. Who has these ICs? If anyone has them tell me.

Hi All!
Is there any news on schematic?

Spectrum XLT

HI!

There is scheme Spectrum XLT, unfortunately, as you can see, copy is bad... However, it is possible to read in certain things

hi Spectrum XLT pcb&hex ????????

schematic and HEX ? - something else?
in your case is better to buy from EBAY.

for me schematic is very useful to take idea and to make with up to date parts.
i made this with high speed PIC and some renovations and now my unit is better than XLT (for test i bought one from ebay)
much faster displaying metal type and signal level - dept
dept is 5 cm moore - coin 2 cm XLT -35 cm , my -40 cm

Hi rumensat
Are you having xlt schematic?
Can you upload it , here or sending to my email ?

i have same schematic giving above
schematic is clear about connections but w/o parts.
parts you can take from eagle spectrum - analog parts.
digital you dont need becose it is syupid idea to use such old and slow processor.

for my project i rebuilt all filters with more effective high Q band pass filters, it took me 1 year to adjust this filters, every time going to mountain for test.
in the laboratory you can not fix them rite way - so much noises.
for this you need scope like Game Boy DSO.

menu - USER 1...6, frequency 6khz...8khz, ground balance -88...0...88, tresh hold 1...88, transmit boost 1...2, amplifier 1...7, discrimination reject 0...190, battery voltage.
sound - high and low freq.
LCD 2x16 , 3 buttons, power li-ion from 4 to 9volt
head -22cm concentric tx33 rx300
discrimination - iron 110 -130, cu -95-80, bronze -50-35, al -20-25, au-3-18, ferrit 190-160

Hi rumensat
Yes, I know about problems for tuning filters. Portable osc. Is very useful
For this matter.
Also I am interest see your schematic.
Regards.

Rumensat, I know this may be very cheeky of me, but I have an Eagle Spectrum and with the right settings it WILL beat a Minelab Explorer EVERY TIME...FACT! What I was going to ask is could you PM me with your filter mods (would these work on a standard Spectrum, have you tried them) and can I be REALLY cheeky and ask for a copy of your schematic and PIC code. I will NOT divulge it to anyone else and am prepared to make a donation to cover your costs.

Let me know I would be VERY interested to build one of these machines or just to mod up my trusty Spectrum.
