Today the preamps for 144 and 432 MHz arrived from Wimo. They are manufactured by the German SHF-Elektronik and powered via the coax-line (My Icom IC-9100 supports 12 volt over coax). Both units have a VOX unit so no need for a seperate PTT-line (for now). Now I only have to find some time to mount them before the first weekend of may contest.
