Long path propagation or short path propagation on HF?

Chordal hop propagation

Past months propagation improved, resulting in relative good propagation on HF. Those who have DX ears must have noticed that 10m long distance propagation acted in a more or less remarkable way. Fellow DX’ers on different forums reported signals with multiple echoes that are certainly not from a CB echo Continue reading Long path propagation or short path propagation on HF?

Has Solar Cycle 24 finished?

Sunspot Cycle 23 and 24 progression

Those who are daily active on the 12m and 10m band must have noticed that propagation was relatively good even excellent during the 3rd and 4th quarter of 2011. The bands, including 6m, were wide open for long range contacts. I observed long path QSO’s, “around the world trip” echoes Continue reading Has Solar Cycle 24 finished?

Nice propagation to test the Moxon antenna

Lucky me!!! No better way to test the homemade 10m Moxon antenna then with current conditions. Best propagation since 2003, definitely! I took the chance to do one on one tests, and results are a bit surprising in a positive way. But first of all for the right comparison: Moxon Continue reading Nice propagation to test the Moxon antenna

Let’s start testing the 10m Moxon antenna, or not…

The 10m wire Moxon

I made a setup with a dipole and the 10m Moxon antenna to compare results. But for some reasons both antennas acted not normally. The Moxon had almost none front to back ratio and the dipole could not be tuned to resonate with a decent SWR. It seemed that the Continue reading Let’s start testing the 10m Moxon antenna, or not…

Moxon up and running, first impressions

The 10m wire Moxon

Since a few weeks the 10m Moxon is up and running. It was quite an easy job assembling and mounting it. I have constructed it in a way that makes it very easy to assemble and disassemble it in case of a severe storm (which happens here frequently). From a Continue reading Moxon up and running, first impressions
