How to fix short coverage on Kirisun Repeater?
- O
  osmithSep 12, 2025
  To address short coverage issues with your Kirisun Repeater: * Verify the duplexer isolation and ensure the insertion loss meets the required specifications. * Inspect the feeder for any signs of damage or abnormalities in its connections. * Confirm that the antenna's frequency range is compatible with the repeater and that the antenna itself is not damaged. * Check for the presence of any high-power radio antennas near the repeater, as they may cause interference.

What to do if my Kirisun TR850 fails to power on?
- I
  Ian TannerAug 21, 2025
  If your Kirisun Repeater fails to power on, try the following steps: 1. Check the power indicator on the front panel. 2. Verify the 13.6VDC input or the 100-220VAC input. 3. Inspect the baseband board input voltage (13.6V) and the 3V3_OMAP indicator (LED6). 4. Examine the DIP switch (J4) code location on the side of the baseband board; it should typically be in the start mode (1, 2, 3 off). 5. Check the baseband board OMAP 24M clock (Y2). 6. Connect the serial port (J23) and check the programming printing information to see if the program loaded successfully and the chip initialized correctly.
