Hi Adrian! Firmware of my Juma PA100-D is now on Version 3.00C Build: 6. FW update worked fine.. A resistor on the frequency sense board made the problems with auto-band tracking in frequency sense mode. All is ok again. It took a long time but this problem was not so important for me. 73 Guntram ...

Thank´s for quick replay dear Adrian. We had a contact before and a tryed to install the new firmware. I used the usb connection cable from my KX3, it has a stereo jack, I got response from the PA but but only for few commands. Then I did not update the firmware and therefore it´s the 1.04 still. ...

My Juma PA100-D does no longer auto band tracking by frequency sense. Manual band selection is ok but since a few month the frequency sense function is not working.
Can anyone help me?

Ok Adrian, I understand. The easyest way is the frequency Sense mode. Otherwise I will look, if I can figure such a Y-cable for my K3X.
Thank you for the help, 73 Guntram oe9dgv.

Hi Adrian!

Thank you for the infos and the firmware update manual, I will try this the next time.

Starting dsPIC Bootoader I get the message: MFC71.DLL is missing on the Computer. I`m using Windows 10.
What is to do? I get response from the Juma with a terminal program.
My second question: I did not find a manual for the flashing procedure.

I`m searching for such a cable to use with a KX3 and/or a FT-817. Any suggestions, where to get or how to configure it?
My second question: Is it possible to use the cat cable from the KX3 with the PA100-D?

Thanks for helping, 73 de Guntram oe9dgv.
