2014-08-25 I created the simplest possible antenna ...2 years ago
I created the simplest possible antenna for use in the 10 meter HF bands: a dipole from recycled utp wire using some turns of coax as 'ugly balun'. I used this Wire antenna calculator to calculate the needed lengths. The choice for the 10 meter band was for a purely practical reason: this is the length I can put up under our roof easily. So I am trying PSK31 on the 10 meter band, around 28.120 MHz.

The first results the past evenings was a constant S6/S7 noise level, which leaves little space for other signals. And absolutely no response to my CQ calls.

But conditions can change, and this evening I am hearing some PSK31 traffic, and IZ3ZOW managed to copy my callsign in Italy but we couldn't make it a whole QSO. I also tried various setting for the noise reduction in the FT-857 radio to see whether that has a positive or negative influence on PSK31. I am seeing other traffic, so the 10 meter band must be opening a bit. I spotted OM0AST calling CQ from the Slovak Republic but he could not hear my signals.

Update: For me that opening didn't last longer than about 20 minutes.
