Problems started. In this location were strong intermodulations from diverse radio and IT equipments exactly on input frequency of repeater. This was the reason to move repeater to nearby radioclub OK2KOS. Relocation and installation was in spring 2006.
Responsible for this repeater is Jarda OK2VLT.
Designer is Vladimir OK2UWV.
Duplexer tuned Pavel OK1DNZ.
Relocation performed: OK2VLT, OK2SYZ, OK2HZ a OK2BMU
Plans to the future :
