Santino (PD8S) called me to help sorting out a problem at the new PI2ASD and PI3ASD repeaters. PI3ASD is causing interference on a TELE2 microwave link. Tough this link works on 13 GHz, the modulator has a baseband working on 140 MHz +/- bandwidth. The PI3AMS repeater is just in the middle of that band, transmitting at 145.7750 MHz. Inteferance was caused by RFI in to the coax and direct RFI into there baseband modulator. The fix was to move the antenne a few meters away from TELE2’s equipment. Too bad they used wrong frequencies they shoudn’t use and it was costing me allmost a full day of labour.
