500kHz in USA

From the LF reflectors I had noticed new LF licences had been issued in the USA and new modes had appeared so it was time to take a look with my HPSDR and DX-B wire antenna

Monday night I looked on 474.2kHz and saw a signal from WG2XIQ (identified by his 12wpm ID) but couldnt decode as WSPR or the new JT9-2 digital mode, indeed they didnt look on the panadaptor like either mode. It was late so I switched off

Tuesday morning I tried the setup on 30m QRSS and noticed a lot of jitter on the Argo display. I was suspicious of the VAC connection between PowerSDR and WSJT-X so I ran a cable from the headphone output of the HPSDR to the computer mic input. QRSS looked fine and was easy to copy

Tuesday evening listened on WSPR on 474.2MHz. saw 2 signals
