Can anyone help with this

Hi to all.
Here i´m sending the pcb that i made for TR locator.
My question is if there are any way to know if the unit is working before instaling the coils?
Instead of U2 (4049) i installed CD4069, that KT315 saids is the same. Phisically was installed has is noted on the PCB.
The detector make no noise, so i really need to know if this is working.
I request to KT315, Geo, Esteban, Detectoman or anyone that can really help me with detail information, because my electronics knolegment is too basic.
Regards
Nelson

Can anyone tell me if is possible to test the sound of TR locator without the coils placed. i mean on the table is there any way to test it before i go to the field.

regards
Nelson

Hi Nelson. Maybe if you put your finger on R13 or on R29 to hear a noise. If you hear the noise then the audio is ok. But if you don't connect the coils you can't test the locator to see if it works.Also you can make 2 coils with small dimensions only for the test. I don't know if you have the full pcb with jumpers. You must connect some jumpers to work the detector. For examle the 4069 wants +6v at pin 14 and (-6v) at pin7. If you have not the pcb schematic with jumpers write me to looking for it and to mail you,

nelson you no worry

nelson no es facil que un circuito integrado se queme, la mayoria vienen con protecciones internas para en caso de un corto circuito, los que si pueden quemarse mas facilmente son aquellos integrados que estan constituidos en sus entradas con jfet o con diodos en sus entradas, la mayoria resiste muchos amperaje, asi que no es posible que esto pase muy seguido, yo creo que el problema podria estar mas bien en un contacto mal soldado, o en que aplicaste mucho calor al soldar, pero por lo regular solo en algunos transistores mas no en todos, ya que la mayoria de los transistores actuales resisten mucha temperatura del cautin, yo te aconsejaria algo, que siempre que instales circuitos integrados les pongas sus bases o shockets, para que asi si tienes una duda de que alguno se quemo, lo puedas examinar afuera, probarlo con circuitos especiales para prueba, y aparte, y para que tambien se puedan cambiar por otros de mas calidad cuando ya este funcionando el aparato
ok pues es todo lo que te puedo decir, tambien es muy importante que pongas las resistencias lo mas exactas que puedas, como se te pide y si no encuentras las que te señalan, pues les pones pequeñas resistencias variables, preset, y ya pre calibradas con el multimetro, asi estaras mas seguro de que el circuito esta en sus especificaciones, yo te sugiero tambien que cheques con una bocinita, lo haces asi, con una de sus lineas la conectas a tierra, luego con la otra linea vas probando todos los emisores de los transistores haber si llevan oscilacion y frecuencia, y asi sabras hasta donde vas bien, o lo puedes hacer ya mas profesional con un multimetro si sabes ya de antemano que medidas de corriente te deben ir dando segun lo tegnico
ok pues revisa todo bien con un lente de aumento, para que veas si algo no soldo bien
un abrazo y ten mucha calma ya que es tu primer dos cajas, y aunque son muy sencillos, el primero a veces causa dolores de cabeza ok nos vemos

nelson is not facil that an integrated circuit is burned, mayoria come with internal protections stops in case of a short circuit, those that if they can be burned facilmente but are those integrated that estan constituted in their entrances with jfet or diodes in their entrances, mayoria resists many amperage, asi that is not possible that this happens followed very, I I believe that the problem podria to be but or in a bad contact welded, or which you applied much heat when welding, but by single regulating in some transistors but not in all, since mayoria of the present transistors resists much temperature of cautin, I you aconsejaria something, that whenever you install integrated circuits you put its bases or shockets to them, so that asi if you have a doubt that some I burn myself, you can examine it outside, to prove it with special circuits for test, and separate, and so that also they are possible to be changed by others of but quality when already the this working apparatus ok because he is everything what I can say to you, also it is very important that you put the resistance but exact that you can, as is requested to you and if you do not find those that indicate, because you put small variable resistors to them, preset to you, and either pre calibrated with the multimeter, asi estaras but surely of which the circuit this in his specifications, I also suggest checks to you with a bocinita, it beams asi, with one of his line it you connect to earth, soon with the other line you are proving all the emitters of the transistors to have if they take to oscillation and frequency, and asi sabras to where you go or, or you can make or but professional with a multimeter if you know beforehand or that measured of current they must be giving segun the tegnico to you ok because it reviews all or with an increase lens, so that you see if something not soldo or a hug and ten much calm since it is your first two boxes, and although they are very simple, the first sometimes cause headaches ok we see ourselves nelson atte. detectoman

nelson, una manera de saber si esta saliendo señal de los circuitos integrados es que sabiendo de antemano cual es el out, o salida le pones unos audifonos, con un condensador y si hay frecuencia de sonido podras escuchar un tenue chillido, asi sabras si funciona o no, mas no siempre te dara esa indicacion sin hay un corte mas atras, o algunos ics no dan corriente fuerte ok detectoman

TR locator

Hi Geo.
Ok i ll check R13 and R29 for a noise.
No i don´t have the pcb with jumpers. This is the version made on Sprint Layout and i don´t know if there are another version with jumpers.
Also, 4069 was mounted exactly has show on the pcb for 4049, is this ok?
Detectoman, thanks for your information and i ll check this when i get home this afternoon, because my vacations time has finish.
Detectoman, gracias por tu información y revisare esto cuando llege esta tarde a casa, mis vaciones han terminado.
Un abrazo.

Buccaneer

Hola Detectoman.
Al margen del detector dos cajas TR locator, sabes tu su el el detector Bucanero (Buccaneer), es posible dejarlo como un dos cajas. Esto lo consulto porque existe aquí en mi País, un señor que arma detectores y los comercializa. El tiene un lindo detector de dos cajas y en sus reseñas de como llego a este detector menciona el Bucanero. Yo se que este es un detector de IB, pero los dod cajas tambien lo son y pense que tal vez el bucanero pueda servir para armar un dos cajas al colocar sus bobinas en la disposicion que tu ya sabes.

Buccaneer (two box?)

Hi detectoman, has i wrote before, i need to know if is possible to make a two box with buccaneer MD.
Here is the link of a Chilean MD manufactures, thar mentions that the first 2 box was tha Buccaneer.

mira nelson yo nunca arme el bucaner, ni tampoco para hacerlo dos cajas, pero he tenido muchos informes de que es un detector que funciona bastante bien, sinembargo no se las especificaciones para sus bobinas, yo creo que ese dato te lo podria dar geo kt315 o carl, pues ellos estuvieron en el tiempo en que se hablo de el, y de que ellos lo armaron, yo aun no entraba en el grupo cuando se estudio ese proyecto, yo creo que si el sevzirfo se te pone dificil debes de dejarlo, o sea relegarlo un tiempo, para despues seguirle, y asi como quieres empezar con otro, yo creo que el bucaner es sencillo, mas no se que tan obsoletos esten ya esos transistores, mas creo que quizas si los podras hallar, y si no pues buscale con otro, yo pienso que el circuito que presento chemelec o sea ese que te envie hace tiempo, el dijo que ya le estaba funcionando bien o sea solo el receptor, creo que chemelec tuvo algunos problemas mas creo que fue solo con el transmisor, o con las bobinas o algo asi, el caso es que no se quiso meter en complicaciones y lo abandono, pero yo creo que es sencillo, y podrias experimentar por ahi, como te digo chemelec dijo aqui que el receptor estaba ya funcionando, mas no recuerdo si dijo las especificaciones de las bobinas, y como tu sabes algunos receptores necesitan las vueltas exactas y otros no, asi que yo creo que si persistes lograras armar algo eficiente, y yo tratare de ver que te mando a tu correo, la verdad los esquemas de dos cajas son escasos, solo andan en la red como unos cuatro o cinco, pero si tu los estudias pronto aprenderas como es facil jugar con ellos modificandolos, ya que algunos trasmisores de ellos se pueden intercambiar, o sea solo acoplandoles los capacitores de bobinas mas especificos
pues llevatela tranquila y estudia paso a paso los procesos y lo que no sepas continua preguntandonos
haber que te puedo mandar en estos dias a tu mail, ok estamos en contacto, y te repito los dos cajas son muy versatiles y practicos, solo tienes que dominar su ciencia, despues te sera muy sencillo
un abrazo hermano y con mucha calma

he never does not watch nelson I I arm bucaner, nor to make it two boxes either, but I have had many information of which it is a detector that works enough or, sinembargo not the specifications for his coils, I I believe that that data podria to give to geo kt315 or Carl you, because they were in the time in which I am spoken of, and of which they armed it, I did not even enter the group when study that project, I believe that if sevzirfo puts dificil to you you must leave it, that is to relegate it a time, for despues to follow to him, and asi as you want to begin with another one, I create that bucaner he is simple, but that so obsolete those transistors esten either, but I do not believe that quizas if podras to find, and if not then buscale with another one, I think that the circuit that I present/display chemelec that is that that you envie a long time ago, said that or the receiver was working him or that is single, I believe that chemelec had some problems but I believe that was single with the transmitter, or the coils or something asi, the case is that it was not wanted to put in complications and it abandonment, but I believe that he is simple, and podrias to experiment by ahi, as I say chemelec to you said aqui that the receiver was or working, but nonmemory if it said the specifications of the coils, and as your you know some receivers needs the exact returns and other no, asi that I believe that if you persist you managed to arm something efficient, and I will try to see that I send you mail to your, the truth the schemes of two boxes are little, single walk in the network like about four or five, but if your you study them soon aprenderas as he is facil to play with modificandolos them, since some trasmisores of them can be interchanged, that is single connecting the especificos capacitores to them of coils but then llevatela calm and studies the processes step by step and what you do not know preguntandonos continuous be one that I can command in these days to your mail, ok we are in contact with the enemy, and I repeat boxes both to you are very versatiles and practicos, single you must dominate its science, despues very simple sera you a hug brother and with much calm they detectoman mexico

por lo general es aceptable que el sonido del trasmisor lo capte la receptora algunos 5 o 6 metros y ya muy eficiente unos 7 seria lo ideal, ya mas lejos quizas estaria demasiado sensible y se veria perjudicado por interferencias, por oxidacion por mineralizaciones, etc no lo se eso es lo que yo he concretado, claro hay excepciones

Two box detector

Estimado amigo.
La verdad es que el TR Locator me ha dado más de un problema. Errores del circuito, malas publicaciones del mismo, diferentes criterios en cuanto al reemplazo del 4069 en vez del 4049, etc, etc, etc.
Ayer modifique los tracks del circuito según lo informado por kt315, para poder usar el 4069. Geo por otra parte me indico que el pin 14 del 4069 debe ser alimentado con 6V+ y el pin 7 con 6V- y si miras el circuito en ninguna parte indica eso.
KT315, publico el circuito esquematico con todos los reemplazos y modificaciones para lograr que este funcione.
Yo por mi parte he seguido al pie de la letra lo indicado en esta ultima informacion esquematica, pero el detector aparentemente no me funciona, asi que voy a armar las bobinas y el soporte para ver que pasa, caso contrario lo dejare momentaneamente de lado e intentare el de Gary. Este ultimo detector me da la impresion al igual como indicas tu, que Gary no le dio suficientes pruebas, asi que voy a ver que pasa y experimentare.
Gracias por tu apoyo y si tienes algo de dos cajas con componentes vigentes que te haya funcionado, te agradeceria si es posible contar con esa informacion.
Una vez mas gracias y estamos en contacto.
Atte.

Dear friend. The truth is that the TR Locator has given me more than one problem. Errors of the circuit, bad publications of the same, different criteria as for the substitution of 4069 instead of 4049, etc, etc, etc. Yesterday i modify the tracks of the circuit according to the informed by kt315, to be able to use 4069. Geo indicated me, that pin 14 of 4069 must be fed with 6V + and pin 7 with 6V - and if you look at the circuit it does not indicate that anywhere. KT315, publish the schematic circuit with all the substitutions and modifications to achieve that this one works. I have made exactly the indicated in the latter schematic information, but the detector seemingly me does not work, so I am going to arm the bobbins and the support to see what it happens, the opposite case will leave it momentarily of side and I will try Gary two boxes. This detector gives me the impression to the equal one as it is you who indicate, that Gary did not give him sufficient tests, so I am going to see what it happens.

Thanks for your support and if you have something of two boxes with current components that you has worked, he would be grateful to you if it is possible to be provided with this information. Once again thank you and we are in contact. Atte. Nelson

Hi Nelson and All. Sorry for late answer but i was to hospital (i just came back at home). As i saw at pcb it is not correct, it wants a lot of jumpers. For example u2 (4069) needs +6v at pin 14, but pin14 is not connected nowhere. If you will look at first page of this thread you will see the pcb posted by Gary that have a lot of jumpers (blue lines). Check the pcb with the schematic and make any missing line and be sure that the detector will work. sorry but i have not time to check the pcb.

TR locator

Hi Geo, and i hope nothing bad at the hospital.
Ok, let´s see, i have check the original schematic, the last one corrected by kt315, the pcb with jumpers made by Gary and the conclusion is, i m confused. You said that 4069 wich is the replacement for 4049, on pin 14 needs +6 volts. Now if you look to Garys mods on pcb, the original schematics and the one modify by kt315, none of this show +6 volst on pin 14. Also if you take a look to the last schematics and parts replacement that kt315 show us with details, we can see the same thing on 4069 (U2). Look to the shematics with 4049 and the other with 4069.
So Geo, Gary, KT315, Carl or anyone that can help, plase take a look to the TR Locator information posted here.

Hi Nelson,

I'm not surprised that the digital inverters do not have the power supply pins shown. This is quite common where digital gates are concerned. However, there is often a table somewhere on the schematic listing these implicit power connections. Personally, having briefly studied this design, I cannot imagine that this detector will work very well.
You probably just need to take this one step at a time. The first step would be to check the power supplies are generated ok. In other words can you measure +6 and -6V at the power pins of all the relevant ICs?
For step two I would check that the oscillator is working, and (if so) does it oscillate at 32KHz? Check this at U2D pin 10.
Step three - Check the outputs of U5A and U5B to determine if the dividers are working ok.
Step four - Check there's a signal across TX L2.
Once you have the TX path functioning properly, you're nearly home and dry.
After that we can start debugging the receiver section.

TR locator problems

Hi Qiaozhi, and thanks for your orientation on this project.
When i read about this detector, everything looks to me not to complicate, for one that don´t have to much knolegment of electronics, but after i finish it, my problems began. I turn the detector on and nothing.Later i found problems with U2 (4049). Then i have to do a replacement with 4069. Now i have to look for power on pin 14, but is not marked on the schematic and also on the pcb....has you can see lots of problems.
Ok, i´ll follow your recomendation and of course all of that friends here on the forum.

Regards
Nelson

Ohh another error . At U5 you must connect pin8 to -6V and pin16 to +6v.
