Mine has stopped locking although working on the VFO. It is still very stable if left on continuously. I have the Siemens D2155 and W3155 tracking osc also useful as a transceiver, and great for LF work. Maybe you could let us know how it compares with the normal LF receivers in current use. I find both of mine much more sensitive and the selectivity is excellent. de Mal/G3KEV > > > >
