Easy Controller for Stack Match 1-2

wiki order

This is universal manual and remote (web, IP, cluster) controller for 1 to 2 antennas stack match with Both In / Both Out PHASE. You can use any RF SM (our or your own) and configure jumpers on front panel for all combinations as you need. There is universal output driver - you can use +12 V OUT or switching to the Ground. IP remote module (IMPERO32) is optional. It offers you another 8 external outputs for another relays - you can switch ON PA, light, TRX etc. Output is again universal (+12V or GND). Controller has also PTT hot switch protection.

Main functions:


Default output setting is with TBD driver. Output control is +12V. If you need to control external devices by switching to ground, you must replace the driver with ULN and change the Jumper settings. ULN is not included. Can be ordered here.

Example for External Relays:

  • You can use another 8 external relays. You can control another 8 things you like. It is simply 8 x ON/OFF
  • Outputs can be configured as: switching to ground or + voltage.
  • Output voltage could be the same as controller supply voltage or different - connected to Vext pin at connector.

  • Optional 8 Relay DIN module:

  • External 8 relay module which could switch external devices. More here:
