500kHz WSPR 24 November

After watching the football decided to have a look on 600m using the HPSDR and the DX-B antenna for 160/80/40/30m which slopes to the north east at a height of 20'. WE6XGR (WE2XGR/6 but wspr takes twice as long to send that call!) said he would be QRV so first look there:-



0442 -19 -1.5   0.499500  0 WE6XGR FN12 50
0444 -23 -1.2   0.499500  0 WE6XGR FN12 50
0446 -21 -1.3   0.499500  0 WE6XGR FN12 50
0448 -21 -1.2   0.499500  0 WE6XGR FN12 50
0450 -22 -1.3   0.499500  0 WE6XGR FN12 50
0452 -22 -1.2   0.499500  0 WE6XGR FN12 50
0454 -26 -1.5   0.499500  0 WE6XGR FN12 50
0456 -26 -1.4   0.499500  0 WE6XGR FN12 50
0500 -26 -1.0   0.499500  0 WE6XGR FN12 50

after WE6XGR faded out just to check the receiver I retuned to WG2XIQ on 475.7kHz who was his usual strength

0504 -5 -0.5   0.474700  0 WG2XIQ EM12 30

Tuning around also heard WD2XSH/31 in VA and WE2XSH/7 in MS

To protect the wideband frontend of the HPSDR (0.1MHz to 55MHz) from the 40m QRSS transmissions I was making I had to use my 1kW rated 500kHz low pass filter in front of the receiver as it was the only suitable filter I had, the smaller ones are in England
