DP0POL on 14 MHz WSPR

 

 

 

The German research vessel RV Polarstern was received earlier this evening with weak WSPR signal on 14 MHz.

1648  -22  -0.9   14.097059    0   DP0POL        JP12     37   3067
1728  -21  -1.0   14.097059    0   DP0POL        JP12     37   3067

Polarstern currently operates in the Norwegian Sea.

DP0GVN: WSPR beacon received on 30m

WSPR beacon DP0GVN (see previous post), located at at the German Antarctic Research Station "Neumayer III", transmits regularly on 30 and 20 m (10 and 14 MHz). 

This evening its weak signal is decoded in Greece. The radio is an IC-706 MkII with a vertical antenna and WSJT-X v1.8.0 software. 

Here are the first three WSPR packets:


1804  -26   0.3   10.140158    4   DP0GVN        IB59     33  12316
1816  -27   0.3   10.140158   -4   DP0GVN        IB59     33  12316
1828  -26   0.4   10.140159   -2   DP0GVN        IB59     33  12316

DP0GVN: WSPR beacon in Antarctica

A few days ago, the ARRL site announced that DARC, in cooperation with two German universities, would install a WSPR receiver and beacon in Antarctica. The receiver is based on the Red Pitaya development board, which can function as an SDR transmitter and receiver. The callsign would be DP0GVN. 

According to the entry in QRZ.COM, DPØGVN is a club station located at the German Antarctic Research Station "Neumayer III" in Dronning Maud Land, Antarctica. The call sign is regularly being activated by station personnel as well as visitors.

This morning I transmitted on 40 m (7 MHz) WSPR with 5W and I was glad to see on WSPRnet that DP0GVN received my signal and reported it to the server.

Now I hope to receive their WSPR signal, they transmit with 5W on a vertical antenna, usually on 10 and 14 MHz, but the noise level at my location is much higher.

WSPR beacons on 474 kHz

Early this morning I switched my radio on 475.6 - 475.8 kHz in the 630 m WSPR band for the first time. I conencted my HF vertical antenna directly to the Icom IC-706 MkII radio, without any matching, filtering or tuning. Only one station showed up, IW4DXW JN64 (1147 km).

WSPR beacons on 1.8 MHz

Last night I left my radio on 1838.0 - 1838.2 kHz in the 160 m WSPR band. I conencted my HF vertical antenna directly to the Icom IC-706 MkII radio, without any matching or tuning. I received a number of European WSPR beacons, the most distant being G3ZJG in IO92 (2497 km) and RX3DHR in KO94KS (2187 km).
