The WX is strange but the Bands are even stranger. Here are my recent logged QSOs, as you can see I have worked short and long skip on 20M, 17M, 12M and 10M. click on log to enlarge
Hello Simon, Your log, what great QSOs!!! Have you ever had the strong condition like this? It is a unbelievable world for me to work with such many stations of other countries, particulaly for me, my station.There are some big japanese stations called Big Gun. I think that they would work with many far stations. But it is necessary to prepare very high towers and big antennas to have QSOs with other countries stations from Japan, I think. But I have only one year of Radio, and I have no experience of the peak of Cycle 23, good condition all over the world. But you have had fantastic QSOs like this, Simon in this season. Anyway Felicitation! Simon. /(^o^)/
Today I managed a nice QSO with Tom ZD7X who is located at St. Helena which is quite a distance away from my location. I managed to work Tom ZD7X with a 5/9 report operating my FT-767GX with my home brew 20m delta loop assisted with the MFJ-969 to tune the antenna with 50 watts on 12 meters. 12M is rarely open and I have only had a few QSOs on this band so I guess the new Cycle has begun at last! Good DX de 2E0HTS 73
This Antenna design was one that I used about 4 years ago, it worked exceptionally well on 80m and 40m. The size of the antenna makes a Half wave length on 80 meters, and with the traps a half wave on 40m with a SWR (standing wave ratio) of 1:1-1.5 across both bands. It worked well also on 20m with the use of an A.T.U (antenna tuning unit). I made my version of this antenna using 3mm multi strand copper cable which I left covered by the PVC insulation. The traps can either be home brewed using some 40mm diameter plastic drain pipe and winding wire around the pipe approximately 10 turns, then connected in line after the 10 metre lengths. Or the alternative is to purchase some commercially made 7.1 MHz traps, and fit them in line the same way. The antenna can be fed with 50 ohm coax with a home brew balan or again a commercially purchased balan. The wire lengths of the dipole are 2x 10 metres and 2x 6.7 metres as shown on the diagram above. This antenna can be mounted quite low to the gr
I came across a simple delta loop design courtesy of dxzone found on the net some time ago and have been planning to give it a go for a while. This weekend I had a couple of hours spare, so I decided to give it a go using some 2mm multi strand wire cable, a dipole centre and a mixture of 75 ohm and 50 ohm coaxial cable. The delta loop is supposed to be resonant on 20 meters but I found it to be a little high so at present I am tuning the Loop with my mfj-969 which copes extremely well. The resonant frequency is 13.2 MHz at the moment so the next chance I get, I shall shorten the overall length making sure that each of the three sides are still equal in length, and hopefully adjusting the antenna for maximum performance ATU free for 14.2 MHz. I believe the miscalculation in the resonant length is probably down to the fact that my wire is covered in the plastic sleeving from the manufacturer which always effects the swr as I have noticed in past experiments with dipoles you always get sl

I hope to see jn4vwh in my log soon!!
As you can see by my log, you dont need to be a "Big Gun" to work plenty of DX...
The cycle is near the bottom going back up and there is many DX to be worked.
So my friend imagine what the bands will be like when the cycle is better good DX Nash....Simon
