HE3OM on 137.7kHz this evening

HE3OM (Switzerland) is currently active during February using an old broadcast antenna 125m long vertical. Signals in Europe are very strong despite an ERP of just a few watts. This was the QRSS3 copy this evening using Spectran and receiving on a pair of untuned earth electrodes 20m apart directly into the FT817 which is deaf at 136-137kHz, i.e. no matching and no preamps.
