There are 3 output combiners. 2 for the 4 pairs and behind the 2 combiners and the last one is getting hot. You see it on the pictures were the coil is soldered.

Yes, I think it´s an imbalance cause I measured the current of the 4 pairs and it´s all the same so the TR´s might be ok. Bad combiners perhaps?

This 100Ohm is grey. I had to change it. The old one was smoking a little bit. Perhaps the combiners are also not exact on impedance?

No, that only looks like in the pics but its soldered to the lowest pin on the blue wire. The RF output is alone.

@Shockwave The purple cable you mean is on the lowest port which is B+ from power switch. @Dirtywhiteboy If you look in the datasheet of the 2879 you see that it´s characteristical dates are given with 12,5V on 28Mhz and then the gain should be a min. of 13db and typical 15,2db. Ok some...

I don´t understand correctly, but I think you mean that the input and output is exchanged. That might be impossible because the high voltage C is only in the ooutput but maybe I´m wrong. Here are some more puctures: http://www.bluelincoln.de/bilder/pa/xforce/1.JPG...

I wrote an email to carl and he said that this thing would work but it dosn´t. He has no shematics or wan´t give it to me. I had not the time to send it back to US cause want to run it on a contest on 10th of January. I did the relay wiring like it is in the dx-1600 shematic so I think it´s...

Hi and sorry for my bad english. I´m from Germany and bought a TNT-1500 from X-force. I wanted to run it on 10m. When It was shipped I hooked up and there was no output and the input vswr was very high. I looked inside and was very shocked about the input circuit. There where some caps in line...
