GSL (russian enhanced version of TGSL)

[reptooyep]

Hi friends,
i just discover a nice version of the TGSL.
I was looking for a SMD version of the TGSL before making my own and i found on md4u site a russian version with both SMD and THROUGH HOLE componments.
http://www.md4u.ru/viewtopic.php?f=25&t=1884&start=250
I built it and made it work in 2 days. I've been working on the TGSL for months without success. I have troubles nulling coils for the TGSL and the KROT2 projects.
But with this version, the nulling has been very simple. Maybe the reason is that i use old fashion ceramic caps instead of cheap chiness caps.
I think this is the reason of my troubles on other projects (when i use the same values with chiness caps, it does not work).
So, here are the files of this project :
tgsl2.zip
BE CAREFULL : the layout appear on copper side so, the transistors and regulators are reversed. I've soldered everything before finding this out.

I have much troubles reading russian forum cause my phone google translator is stupid and the translation has no sense

The layout is smaller than TGSL cause all resistors are SMD. the board is 7X10cm.

Good luck

Hi reptooyep,

You can make a movie and post it on Youtube with the result and SMD mounting please?

Replace ceramic capacitors polyester and get a good result. I recommend to replace the C28-C29 C31 S30- scheme and on 4,7mkf nonpolar capacity.
Good luck

Hi, i did not make a video yep cause i have troubles with the discrim circuit. I have to check this later.
I posted my thread just after my first air test, i'm amazed that a 1 euro is detected at 30cm.
Yesterday, i tryed the unit on the beach and i had junk signals. It's unusable on the beach but maybe my circuit has a problem.
I'll test my resined coil with my TGSL unit. I also spent few month trying to make it working.
