(I checked this today in transmitting with my LF-Exciter). So far so good, but this receiver is just a fixed frequency receiver (quartz crystal of 131.7KHz). Actual receiving frequency is "134.2KHz".=20 Does anyone know this receiver and if yes, is it possible to trim it for ~137.700KHz? Will it be a new crystal or is it just adjusting the band pass filters? Many thanks and a nice weekend vy73 Marco DD7PC mailto:dd7pc@gmx.de http://dd7pc.qsl.nu
