Hi Barb,
thanks I will try to replace the 4 BS170 and the 74ACT . In addition I will order two zener Diodes. But it is not easy to get these Zener diodes . High costs of shipping.
?We know us from the crkits io :) .The QDX is such a good trx but Im angry a little bit . especially because I don?t see the reason of a fault. VOltage <= 12 V, swr better 1.5
