Hello i have received my assembled QMX+ a few days ago and go the power cabled assembled feeding this unit with 11.80v of dc. (12v model)?

I can putty into it and see the hardware tests pass, the data sheet shows all good on all bands.?

It powers up and down fine. I have not xmited w it yet.?

I can viewed the manual that i downloaded and printed out for vx.0027 of my software?

Still not sure of how to operate it.?

When i turned on practice mode or keyed i get a continuous series of dahs all the time. Even with key and cable disconnected. ????

If i put the unit in vfo mode it seems to go away. Volume., are and band changes seem ok.

I got thsi to stop but not sure how???

on any band cw i get a continuous audio chuffing sound like its sampling or some such.?

I can use some help or guidance on this and i am not transmitiing until i get this sorted out.?

Can i or did i change a settting in the config when i puttyed in?

Maybe its my ignorance of how it operates??

Thanks in advance?

Hi Charlie,

"i get a continuous series of dahs all the time. Even with key and cable disconnected."

I wonder if you have a short on the 3.5mm TRS mic/paddle socket.

Check that there are no solder blobs across all of the pins on the TRS socket and the mini board connecting to the main board.

Also, make sure that the underneath of mini socket board is not touching the casing when you slide the board in (assuming that you have it in a metal housing). There isn't a lot of space between the underneath of the mini TRS board and the casing. I had a slimier issue after completing my QMX+.

Thanks for the replies. I open a?ticket w QRP LAbs and Hans responded that he is sending a new unit.?

He agrees something is amiss with this one.

?He indicated he will pick?up the old unit when he is Dayton in May.?

I thanked him fpr the great support.
