50w amp with qdx v3

Andy KF0EZV #90525 Is there a specific/recommended ptt cable to use between the QDX and the amplifier??
Evan Hand All Messages By This Member #90537 High Andy, Unlike the QCX, the connection of the QDX to the 50watt amp uses a straight-through cable.? Since the Roing is the +5volt PTT signal, you do not need to worry about the tip connection.? There is not a connection to the tip in the 50watt amp. I used a 3.5mm stereo audio cable.? That is one with Tip, Ring, and Shield.? NOT a Tip, 2 Rings, and Shield. 73 Evan AC9TU
Hans Summers All Messages By This Member #90538 Hi Evan That's right, but QCX+ and?QCX-mini also have a straight-through cable, the same. Only?the Rev 1 PCB of the QCX+ had tip/ring reversed (my stupid mistake); all subsequent PCB revisions are OK.? 73 Hans G0UPL toggle quoted message Show quoted text On Fri, Aug 12, 2022 at 1:28 PM Evan Hand <elhandjr@...> wrote: High Andy, Unlike the QCX, the connection of the QDX to the 50watt amp uses a straight-through cable.?

Evan Hand All Messages By This Member #90539 Hi Hans, Thank you for the clarification.? I have only used the QCX+ rev 1 with my 50watt amp, which I used for my reply.? The others are for different bands, so I did not try them.? I will be sure not to mention the reversal again to help in confusion reduction. 73 Evan AC9TU
