The K3S must be working alright on 475kHz!

Having done the K3S upgrades for 475kHz see here it was time for DX.  I was duly rewarded with my First transatlantic WSPR decodes of the year using the K3S and the PA0RDT whip in the loft:-

Timestamp           Call MHz         SNR Drift Grid          Pwr  km
2016-04-01 23:52 G3XIZ     0.475785 -24 -1 IO92ub 0.5  137

Not band with the takeoff in that direction!

A night on LF

Having repaired the wind damage to my WA1ZMS loop I thought I would take a listen around 500kHz

Using the loop to the Anan-10 with W5WC mrx software and wspr from K1JT I could see some local signals on wspr and the multimode signals (cw and psk) from WD2XSH/7 in LA. I quickly decoded the local signals as  WG2XXM (a new state for me OK!)  and WG2XIQ.

I then decided to hook up the anan headphone output to the Nexus 7 and see if Droidpsk could decode the PSK signal (while still decoding WSPR on the PC)



WD2XSH/7 is the signal in the green box. WG2XIQ is the signal at the 5 marker, WG2XXM is the signal slightly hf of WG2XIQ. You can see they are timed WSPR signals (but not decode them on android!)

I left it running for a while and started to see two more signals, WD2XSH/12 in CO (DM79) at 1092km and the best (WSPR) dx WG2XJM in EN91 at 1746km

I then had a listen on cw and heard WD2XSH/31 in VA again at 1651km   Signals faded out at 1236z, WD2XSH/12 in CO was the last signal seen

Not bad for an 8 turn loop!
