Hello,

I just bought a FDM 10712 from Universal Radio and have two questions that are not made clear in the supplied documentation.

1. What polarity is the DC Jack? Pin Positive or Negative?
2. What is the purpose of JMP1 on the board?

Hello,
I use ELAD FDM77. In my handbook from the receiver the central pin is +
I think its also on your interface.

Hello,

Thanks for the information. I got an email that said jmp1 was to shift the IF when used with certain receivers.

Hello Eric,

I have research in my adress-book from electronic mail-box. I have found follow adress, if you can not find a solution:
franco@eladit.net.

Franco Milan work in the DRM departement by Elad (www.eladit.net).
I have also a little difficulty with the Dreamsoftware(1.6.1.cvs): why my receiver use an output slot USB 2.0 and must be connected on a USB 2.0 slot on the pc, any fonctions don't work: not reglage from the HF AGC, Notch filter and no indication from the s-meter. I hope that a solution will be find in next time.
