I am back from a visit to Denmark, and found a nice little setup for watching QRSS.
I was using the Eee 1000H - running SpectrumLab - with a Sony SW-1 receiver (and an audio cable)
Everything can be run from a battery, so no problems with hum.
The SW-1 has AM and SSB reception from 150kHz to 30MHz with 1 kHz steps, so by calibrating with the Russian RWM time signal transmitter I could find the QRSS band on 30m. The SW-1 needs a bit more antenna than the built-in telescopic whip, so a wire antenna was attached to the whip. The SW-1 does have an input jack for an (active) antenna, so that will be tested later. Probably a small tuned loop antenna.
I was not using it a lot, so very few signals were heard. The concept worked well enough, and the frequency drift was not excessive. I set the bandwidth of the "grabber" to 200 Hz, though.
Nice and easy low power portable receiver setup, I may use it at home as well, with external power supply.
Next step ? : maybe using the Asus Eee4G with linux/WINE, running SpectrumLab - it could hardly get any smaller.
Further, a simple DC-RX - maybe powered by the USB port ?
FT8 it's a winner! - 28 MHz FT8 mode last night open to VO1NE GN27 S.A. PY LU CX CE good signals after repairing the wire antennas damaged in the storm last week 80m...
