[detectoman]

geo: one question for you., maistro, what is the mejor detector diagram? delta pi?
and the most little diagram also effective for build

geo una pregunta para ti, maistro de los detectores, jejeje un abrazote, ahora pregunto, cual es el mejor diagrama facil y conseguible en la red, es acaso el delta pi, o hay otro? y te pregunto si existe un sencillo diagrama ruso o ingles, o del que sea ,que siendo pequeño y facil de construir sea muy efectivo? cual viene siendo?

nos vemos brother

Detectorman... Esta mejor si tu escribas en inglés y tambien en español. Los gringos no intienden lo que tu dices. Si tu escribes en inglés y español, entonces todo entenderá. Tu hablas muy buen inglés. Todos pueden entender lo que tu dices.

English version:
Detectorman... It is better if you write in english and also in spanish. The gringos don't understand what you say. If you write in english and spanish, then all will understand. You speak good enough english for us to understand.

what is the value of Tr1?

are PR1 and Tr1 both trimmer pot?

I do not know what PR means

Hi.
Tr1 is a test point. Pr1 is a trimer for frequency regulate. I cant see any trimmer or pot with name Tr1.

Have a nice day.

thanks Kt315

I looked at schematics.
this list is for delta.
I still have questions.
in schematic there are components like vd16,vd17,c30,c31
where will we use them.
will not we need them?
this list just gives components on pcb ,am I right?
can you give me full elements list that I have to buy from electronic store
including potensiometers,current meter scala,on/off button and others

Hi.
VD16, VD17 are leds. One for power on and the other for low battery. C30 and C31 are electrolytics capacitors. You can use only one (no c31).

Hi Detectoman
I see tha t you wnt to help me
THANKS A LOT
but I can not understand your language.

[detectoman]

respondanle a okantex el tiene inquietudes y necesita su opinion, acuerdense de cuando ustedes tambien necesitaban de la dirigencia de otros, creo que okantex empieza y necesita su supervision, y haganlo muy detalladamente y claramente, claro esta los que saben, si yo supiera le diria, pero tambien soy neofito en esto, claro me las ingenio para entender, pero okantex esta metido en un proyecto que para el es muy desmesurado quizas de acuerdo a sus animos

ok help to okantex

Hi kt315

Thanks.I know that pages.also I have them in my PC.
but my problem is that I can not identify all components.
at first I wanted to build xr71 but as you can see in the link you gave.there are some components not written openly.like some transistors just called NPN but what are they.I looked at geo's schematic .there I saw two types BC214 and BC284 .which one is which one?
this is my problem.
if you can enlarge the picture of components and add absent ones in paint .
it would be easy to build.
And another problem is that in delta schamatic there is C30 ,C31 ..but in pcb layouts there is no C30,C31 ..
delta is commercial and can create problems for our site.but you can help for xr71 .nowadays no body produces it as commercial I think.
can you control and correct all components for us please
thanks
have a nice day

[kt315]

you could be turn on Search engine in the forum and to see there are much about DP. the people likes to double one subject in much lines... why - I do not know (((

for example

Hi Lake

thanks for your offer first
but as gemini build it wrong through the sheet ,I can also build it wrong.
I build two detector before and non worked.
if someone helps with pictures we could build for us, too.
for example Geo's pcb layout is much better.because it showscomponents with numbers in schematic.that is okay but still I can not find C30,C31 in it.
if somebody puts pictures of finished pcb .and connections of outer parts ,it will be good for all.
thanks all

Read from schematics?

I constructed mine from schematics.
