Hi,
Wasn’t there a kit to build a receiver for saq (sold at grimeton) ?
Or is there some schematic around to build a simple receiver?

  They still have them. Given the upcoming transmissions I could not resist ordering a kit 🙂

  Hello,
  For SAQ’s 100th birthday I built this transistor receiver this year:
  https://www.wumpus-gollum-forum.de/forum/thread.php?board=58&thread=410
  Basically:
  HF selection (resonant loop antenna, outside!) and HF amplifier
  Oscillator (quartz and divider module)
  Down mixer (for audible sound e.g. 800-1200 Hz)
  LF selection and LF amplifier
  
  Even just one HF+LF selection would be sufficient,
  but there are these strong naval stations that can be heard in this case.

  ciao a tutti.io ho appena costruito un ricevitore per SAQ valvolare.Non e’ a conversione.Il sistema e’ composto da una antenna quad con 138 mt di filo,un preamplificatore vicino all’antenna,un primo stadio a 4 celle accordato a 17200 hz,poi lo stadio valolare con altre 2 celle accordate composto da una ef86 come amplificatrice,una ecc83 come oscillatrice ed una ecc85 come comparatore.in uscita a questo stadio c’e’ un filtro passa basso a 3000 hz ed un riconoscitore di toni con lm567.completa il tutto un decoder a display per la lettura del codice morse.per le prove ho realizzato un tx cw da 8 watt a 17200 hz.modulando il trasmettitore in cw con un generatore di codice morse sembra che la cosa funzioni perfettamente..adesso aspetto la prossima trasmissione del SAQ per testarlo definitivamente.auguratemi buona fortuna!grazie ancora di cuore!
