This evening I decided to complete a test using two different HF setups in an effort to compare the receiver performance of my antennas. Radio 1, Kenwood TS 990, doublet antenna 10m per leg @ 9m Radio 2, Elad SDR, Wellbrook RX loop @ 3m I decide the best way to test on receive would […]

I was looking for a simple project to split a RX antenna into two receivers, my Wellbrook loop feeds my Kiwi SDR and also my HF radio. The Wellbrook loop is very capable at LF and MF frequencies, and so makes a great alternative for RX on 472 KHz and even NBD reception should my […]
The Kiwi SDR and Wellbrook loop provide a very good single antenna solution for 0 to 30 MHz shortwave reception. The Kiwi is capable of displaying the complete band of 30 MHz, but the disadvantage is the very high power from some of the LW and MW stations can cause the receiver to overload in […]
Following on from the previous post, WSPR reception continues mostly 24×7 with a focus on MF. As previously described the setup has been operating for a couple of weeks now, and its a good time to review the WSPR spots. Best DX Spotted 472 KHz Call Grid Pwr km az WA4SZE EM65 0.2 6826 45 […]
WSPR reception 24×7 has always been something I have wanted to try. The problem is trying to find a transceiver, computer, antenna combination that will allow this with minimum fuss. 472 KHz Reception Computer You won’t need a very high spec computer, but if you are leaving it on 24×7 low noise and power […]
NDB are low power beacons in the 250 to 550 KHz range. The beacons are usually situated at a landing strip/airfield / oil platform to aid navigation. They are non-directional so use a vertical omnidirectional antenna, and reasonably low power. The ERP is very low, as the physical size of the antenna restricts the efficiency […]
