IF 144MHz| RF 2256MHz|
IF 432MHz| RF 1968MHz|
IF 1296MHz| RF 1104MHz|

Table 1. IF frequencies options
TX mode, the MK4 Upconverter will turn to TX mode when some IF RF is detected on IF in port.
TX-mode will trigger from any power higher than 100mW in whatever IF 28, 144, 432 or 1296MHz
The Hold On TX mode is 250ms
External 10MHz reference:
-Remove JP2 Off (this jumpers turns OFF the TCXO; this avoid any dual reference signal on input resulting in erratic output signal.)
-Swap JP1 from Internal position, to External position

  • *Low IF input can increase the converter spurious emissions. Using this IF, some external Band Pass Filters might be needed between the converter and power amplifier.
  • 144Mhz and UP IFs are well recommended.
