sw dead on radio shack dx-390
 

the shortwave section of my dx-390 is deaf. I am receiving ok on the mw
portion and also replace q1 awhile back when the am went dead. Im wondering
which transistor is associated with the sw portion. I haven't tried anything
yet but am thinking on switching out q2 as it is right next to the antenna
input. Comments would be appreciated.
Thanks...... Jim

Jim, wait a couple days before you open your 390 up. Huge solar
storms are hitting earth right now, my 390 was pretty dead Sunday
also. Jimmy in Charlotte

Greetings Jim!
I have had the same problem with my DX-390. I can't remember which
transistor it was on the board. I might open it up and see if I can
remember.
Conditions were bad Sunday. I heard almost nothing at all on 75 meters
on my FT-980.
One more thing to try on the DX-390. Attach an external antenna via the
antenna connection plug on the left side. One time mine would not
receive squat via the whip, but connected to an externa antenna via the
antenna connection on the left side it came right to life. That time
the whip antenna had somehow broken it's connection with the board.
Good luck and have a great week! Jon.
