Greetings,
Using my QDX for the past year or so. Very, Very happy with the radio.
Last night I noticed I lost reception. Checked WSPR for reception of any kind..... nothing.
9 volts in and 4.2 watts out according to my meter and very limited reception.
All sorts of activity on 40, 30, 20, but no or limited reception on WSJT-X 2.6**
Any one have or know a thread on this?
(Two nights ago made 5516 mile contact and made Ukraine and Slovenia last night) so it was working fine.

Thanks
James?

Q6 failure has been reported, possibly static from antenna.
Or, a bad joint showing up.

Thanks Alan?
I will take a peek today when I have time.
I'll let you know in a few days.

Does the waterfall change if you disconnect the antenna? Are you receiving anything or just dead?

Reboot the computer?
Good luck,?

Mike, all
Just a round trip ticket to what I found.
It took me a while to get to the bench...... school has started... busy, busy.?
I did change out the BS170s when I found the tuner (MFJ969) bought new 26 years ago has a bad solder connection in the back of the large induction coil.
The roller bar was not making connection. That's why the error was intermittent and all over the place.

I noticed this had effects on the other radios in the shack I didn't catch right away.
I thought it was my imagination or......... age? Nah.... couldn't be that?
I started checking everything.....?
I put on an auto-tuner from another maker and found no problem with any radio including the QDX.?
The change for the BS170s was just a precaution.
The unit from MFJ was repaired after I found the bad connection.
All is well with the world and back in the air.

Thanks for your help and encouragement.
