MINERO

Yes Goldfinger...it is military geiger counter.
But label is DR-M11B.
Serbian army used it long time ago.
Is it Serbian product or not, i am not sure at all.
From my earlier experiences i already know that many devices
Serbian army used (former Yugoslavian army) are mostly USA products,
like many models of radios from RCA and Motorola etc..etc..
I still have in my showroom famous ANGRC-9 (GRC-9) SW radio
USA product....it was used in Vietnam,Cambodia...Korea
The very same radio Yugoslavian manufacturers reproduced for
army needs in period 195x-196x (i am not sure), by some
military contract between USA and Yugoslavia, at the time.
SO i presume a lot of other devices comes here the simillar
way. Many of devices are whole Serbian products(EI Nis), but many
of those are not, but licenced, mostly from USA.
I bought this counter on second hand market. It is quite
accurate. Works very fine. I was experimenting with it like
with many more devices i have, just to establish some sort
of cognitions....
The smaller device is digital gas detector, some French
product (i presume since had label on French)....
But i was modding it many times, as you can see some wires
out of small hole....I used MAX232 (Carl's section..)
to convert some signals from it and later analyze with
some pc software....Various experiments so far...
It will need much more space to explain those..but i guess
no need for that. This suppose not to be place to bug other
people with my wierd ideas for now..
My main interest are metal detectors, since i am not expert
for those(i do consider myself a sort of expert for radio only)
i collected so many various detectors(proximity,gas,ef,infra...
ultra..., radio..., blah,blah..etc) so i can experiment,mod,
crack,compare.....etc.
All of that due to learn more,understand
more,gain more....
I am in ages(40) which are hard to start all over
again...so i am trying somehow to eke all those about m.detectors
i have been missing so far...A lot of has been done so far!(over
15 years)
That's why,i am so "brave" to come here and claim some claims!
I do not have any paper or data more on this counter...
If you have or manage to find something more about it, please come here
again and post it. I would like to experiment more with it.
I would try to trace schematic of it and later to post on this forum
if somebody interested, although it's not a big deal. A lot of newer
and easier geiger counter projects you may find already on the .net
