TA7358 SCHEMATIC RECEIVER

TDA1046 DOUBLE CONVERSION RECEIVER

UN  MIC RECEPTOR CU FOATE  BUNE PERFOMANTE  CONSTRUIT PE 14MHZ . ARE UN FILTRU  TRECE BANDA  SI UN  MIC  AMPLIFICATOR  CASCOD CU  TRANZISTORI  BF256A .URMEAZA  UN MIXER IN INEL  CU PATRU DIODE  DE TIP EFD  CU GERMANIU , DAR MERGE SI CU DIODE  CU SILICIU. LA INTRARE  IN MIXER  ESTE UN COND DE ACORD PE  14MHZ NUMEROTAT CX1. AICI CU UN   COND .VARIABIL CONECTAT SE VA FACE ACORDUL  PE MAXIM  DE SEMNAL. DUPA  GASIREA  VALORII  SE VA  CONECTA  UNUL FIX. TOT ASA SE VA  PROCEDA  SI PENTRU  CX2 .  CX1  FIIND PENTRU BANDA  DE 14MHZ ,  IAR CX2 PENTRU  PRIMA MEDIE FRECVENTA.  COND CX3 ESTE  PENTRU CEA  DEA  DOUA  MEDIE  FRECVENTA SI  ACESTA ARE VALOAREA  INTRE 820PF  SI 1000PF .DEPINDE  DE  CE VALOARE  ARE  FRECVENTA  ,455KHZ  SAU  500KHZ. FRECVENTA QUARTULUI  ESTE INTRE  8MHZ  SI 10MHZ. DE VALOAREA  LUI  DEPIND FRECVENTELE   INTERMEDIARE  SI FRECVENTA  OSCILATORULUI  VARIABIL !!.  UN  EXEMPLU . DACA  AVEM QUART  DE  10MHZ  , ATUNCI  VFO  VA AVEA 4.5 LA  4.850MHZ. PRIMA  MEDIE  FRECVENTA  VA  FI  PE  9,5 ,  IAR  CEA  DEA  DOUA  PE  500KHZ . LA  PINUL 3  SE  INJECTEAZA  SEMNAL  DE BFO .MULT  SUCCES  SI  MULTE  73  DE YO6QCM 

A  SMALL  RECEIVER WITH VERY  GOOD  PERFORMANCE. Is BUILT for 14MHZ. A BAND PASS FILTER And A SMALL AMPLIFIER With TRANSISTORS BF256A CASCOD.A MIXER IN THE FOUR-RING-TYPE DIODES EFD WITH GERMANIUM, BUT IS OK WITH SILICON DIODES. ENTRANCE into the MIXER is a COND AGREE on CX1 NUMBERED 14MHZ. HERE WITH A COND.VARIOUS CONNECTED WILL MAKE AGREEMENT ON THE MAXIMUM SIGNAL. AFTER FINDING THE VALUE WILL CONNECT ONE FIX. SO, TOO, WILL PROCEED To CX2.  CX1 is for the 14MHZ, and the AVERAGE FREQUENCY for CX2.  CX3 is for  the SECOND FREQUENCY and the AVERAGE VALUE BETWEEN 820PF and 1000PF.DEPENDS on what VALUE HAS the FREQUENCY of 455 kHz, or 500KHZ. COMMON QUART is BETWEEN 8MHZ and 10 MHz. FREQUENCIES DEPEND on the VALUE of INTERMEDIATE FREQUENCY VARIABLE OSCILLATOR!.  AN EXAMPLE. IF WE HAVE 10 MHz, then QUART VFO WILL HAVE 4.5 to 4.850 MHZ. The FIRST FREQUENCY WILL BE on AVERAGE 9.5, and the SECOND on 500KHZ. To PIN 3 SIGNAL is INJECTED BFO.      GOOD LUCK and 73 YO6QCM

TA7358 CU BF256 PE AFI

AM SCHIMBAT CLIPUL CU UNUL  MAI SCURT. ACUM  SE POATE  AUZII SI O STATIE DIN AUSTRALIA . RECEPTORUL FUNCTIONEAZA PE BANDA  DE 14MHZ. AFI ESTE  PE 8MHZ SI AM MONTAT LA INTRARE SI IESIRE DIN FILTRU DE QUART CATE UN ARF CU BF256. FUNTIONEAZA  EXCEPTIONAL. TOTODATA ARE SI LA ETAJUL DE INTRARE UN MONTAJ  CASCOD CU ACELASI  BF256 CARE  ESTE SI  COMUTABIL  CU UN MIC  RELEU  OMRON  .ESTE  SENSIBIL SI SUNT FOARTE  MULTUMIT  DE TA7358.       73  SI SUCCES

I CHANGED THE CLIP WITH ONE SHORTER. NOW YOU CAN AND IT SAID A PLANT IN AUSTRALIA. The HANDSET RUNS on the 14MHZ. 8MHZ DISPLAY is on and I HAVE MOUNTED at the ENTRANCE and EXIT of ONE QUART MAKER ARF with BF256. EXCEPTIONAL WORK. At The SAME TIME HAS The INPUT And A CASCOD With The SAME MOUNTING BF256 Which Is ALSO SWITCHABLE With A SMALL RELAY OMRON.Is SENSITIVE And I Am VERY SATISFIED With The TA7358.       73 and SUCCESS

SCHEMA RECEIVER MC3362

O SCHEMA SIMPLA DE RECEPTOR SSB CU MULT LAUDATUL MC3362 .ESTE BUN INTEGRATUL DAR LA CATA FAIMA ARE NU MERITA BANII .MAI BUN ESTE UN TDA1046 SI ESTE MULT MAI IEFTIN .ACEASTA SCHEMA ESTE REALA SI FUNCTIONALA, SPUN ASTA PTR,CA AM GASIT MULTE SCHEME PE NET DAR INTENTIONAT SUNT OMISE UNELE CONEXIUNI ,SAU SUNT ADAUGATE ALTELE ASA DOAR LA DERUTA .TOT CE AM PUBLICAT EU A FOST REAL      73  SI SUCCES


A SIMPLE SCHEME Of SSB RECEIVER With MC3362.THE IC IS GOOD BUT THE FAME IS NOT WORTH THE MONEY.BEST Is A TDA1046 And Is MUCH Cheaper.THIS SCHEME IS REAL AND FUNCTIONAL, I SAY THIS, I FOUND I LIKED SEVERAL PLANS ON THE NET BUT INTENTIONALLY OMITTING SOME CONNECTIONS ARE ADDED OR OTHERS, JUST TO CONFUSE.EVERYTHING I'VE POSTED I was REAL 73 and SUCCESS

MINI DSB TRANSCEIVER IN 80M CU TBA120

TDA1046

un receptor cu dubla schimbare de frecventa ,pe 8mhz si 455khz.are in componenta sa mixer cu ROB641,sau SL641 , un integrat foarte bun .tot aici am folosit si CA3028 sau ROB3028.amandoua sunt foarte bune ,insa am ramas in montaj cu ROB641,ptr.ca celalalt vreau sa-l folosesc in alt montaj .media frecventa pe 8mhz este cu trei bobine si un BF256 pe post de amplificator

urmeaza TDA1046 .un integrat perfect si complet, are tot ce-i trebuie , sesibilitate,  raa,  stabilitate etc..

se poate compara oricand cu oricare similar din clasa lui, si asteptarile sunt imediate fara prea mult efort la aliniere

incercati si nu veti regreta

a receiver with double frequency change, 8mhz and 455 kHz has component mixer with ROB641, or SL641, an integrated very good ... here I used CA3028 or ROB3028. and both are very good, but I stuck in the mounted with ROB641, other ptr.ca want to use it in other media montage 8mhz is common with three coills and a BF256 as follows TDA1046. amplifier an integrated seamlessly and completelyIt has everything i need, sensibility, raa, stability etc. ..
You can compare anytime with any similar in his class, and expectations are immediate without too much effort at alignment try and you won't regret it

HOMEMADE DIRECT CONVERSION ON 80M

un trx  simplu dsb in 3.5mhz .la receptie foloseste TBA120 care mia placut mai mult ca TAA661.urmeaza un filtru audio , un amplificator  cu lm741  si un final cu TDA2003 la emisie are un formator dsb cuNE612 urmat de trei etaje amplificatoare ,ultimul fiind cu IRF530.puterea de emisie este de 5w , se putea si mai mult, dar am preferat asa ca sa nu am probleme de tvi cu vecini

a simple dsb in trx 3.5 mhz. reception at TBA120 which uses more pleasant as TAA661. follow a audio filter, an amplifier with a final lm741 TDA2003 emission has a former at dsb cuNE612 followed by three floors, the last being amplifiers with IRF530. transmit power is 5w, could have been more, but I preferred so she doesn't have problems of tvi with neighbors

HOMEMADE TRANSCEIVER WITH TA7358 ON 20M

primul meu trx cu filtru de cristal facut de mine,dar si prima utilizare a integratului TA7358. un circuit foarte bun,si nici scump.sper sa fie folosit  cat mai mult  de radioamatorii romani ,si nu numai. cine este interesat ma poate contacta pe >> yo6qcm@gmail.com

                                                              73 si mult succes  

my first trx with Crystal filter made by me, but also the first use of integrated TA7358. very good circuit, nor expensive. I hope to be used as much as possible of the  radioham . who is interested can contact me on yo6qcm@gmail.com > > 73 and good luck
