Setkání příznivců QRP - Chrudim 2010
Submitted by ok2bx on Wed, 2010-03-31 20:21Delší dobu nás přitahuje myšlenka QRP techniky a provozu. Nedávno jsem postavil AS-80 CW transceiver z dílny Alexe OM3TY. Byli jsme oba poprvé nadšeni, jak pěkně poslouchá. Už dříve jsme věděli, že se nadšenci QRP schází každý rok v březnu v chrudimském domě techniky a sportu. Letos jsme si řekli, že u toho musíme být i za cenu, že tam pojedeme jen na chvilku v pátek večer.

Quite many steps, especially if you repeat it more than once..

Submitted by ok2bx on Fri, 2010-03-05 22:43Nedávno jsem potřeboval spínat hlasovým signálem výstup pro TX. Přemýšlel jsem, jak to elegantně vyřešit. Neměl jsem ani velké požadavky na délku trvání sepnutého stavu VOXu. Stačilo mně, když délka sepnutí voxu byla 5 sekund. Citlivost je nastavena 1. stupněm OZ v modulátoru a úroveň pro sepnutí je okolo 0.2V šš při napajeni IO 4538 z 12V. Jednoduché, laciné a krásně funkční. Zbytek najdete na schématku a připojených obrázcích…
