Yes! I'm having fun with transmitting. I'm nearly done with MF and am looking forward to rewiring the multiplier for LF. The PA is supposed to be broadband so perhaps it will work at LF without change. I've probably got a few too many turns on the transformer anyway for MF, it might actually run better at LF. I just need to extend the antenna, a few more hundred metres of wire strung through the trees, or maybe I wind some wire around a bucket instead. Either way, yes LF soon I hope and it will be better for EbNaut. MF is a bit of a struggle. Did you the see the mess my phase was in by the time it reached Markus' receiver? LF means I can use longer symbols and less ERP. I've ordered yet another 10MHz GPSDO, there are many on EBay from China at the moment for a reasonable price. When that arrives it will probably go into service for a 2-axis LF rx. It would be fun to put one of those steerable spectrograms on LF. No sign of an MF decode from Italy last night.

Tonight I might give it one more run, after 22:00 when the propagation has settled down a bit. -- Paul Nicholson --
