Grrrr… 10 meters is open and I can’t use it!

As many of you know, 10 meters is seldom open these days.  It is today, however, and I got excited because I can hear MANY stations.  So I tuned one up and when he called QRZ, I tried to respond.  And I got nothing, only minimal power out.  Adjusted everything I could but still nothing.  Grrrrrr…  I need to get this radio working properly on 10 or find one that does!
