Nice pictures Jeff! I went on a 3 week vacation just on the day this operation started.... If I had known ... Seems I am about the only Topbander together with the dxpeditioners missing 7O6. However,
I use twinlead (DX-wire or Wireman) 300 Ohm, less attenuation compaired to RG58 and small. not much windload. Doing its job for over 5 years now. Only fixed at the ends. Kees, PE5T I use ladder line
05:00 UTC The 3501.5 carrier is s5/s6, some qsb comming from north west, so not from the carribian Kees, PE5T The 3501.5 carrier very solid in Western Canada- s-7 or so at VE6WZ....it must be **real*
Hello, In my qth you need at least 30 dBm (1 Watt) for reliable measurements with a broadband detector. The 160m antenna picks up such an amount of signals that with less power you do not get correct
Hi Felipe, Nice story! I was one of the lucky ones (with PA3FQA) and I even worked you twice, due to the up1, up2 etc confusion. tnx, Kees, PE5T Hello folks, I was part of the ZY0T team on 2009. I br
I have a north-south switchable 21m high phased pair for 80m with 1/8 lambda spacing. It is optimised for 3520 kHz, the feed -Christman-system was made according to ON4UNs book and software. Measurem
Tom, Thanks for your reaction. At 50m distance of both verticals I have a 16m high tower with a 3 el Steppir. This tower has a radial system and is shunt-fed tuned for 80m. There is some interaction
ZL6QH is the only Long Path 160m qso I ever made. Pity it had to switch off! PE5T Thanks Frank I was previously the chair of the Quartz Hill User Group responsible for the ZL6QH station. We undertook
Hello Filipe, Yes, I have such a system. Cost me several days to optimize it. My comments. The 2x157 and 39 degrees phasing lines are based on very good earth systems (2-3 Ohm). When your radial netw
Paul, Your feedline is about 350 feet. That is (with RG213 -velocity 0,66-) close to 1 wavelength. With 1 wavelength feedline, the TX antenna is floating when the feedline is open in the shack. Depen
Thanks Jeff for this contibution. Jack was one of my first contacts over the ocean. Kees, PE5T Verzonden vanuit Mail voor Windows 10 Van: k1zm-- via Topband Verzonden: vrijdag 10 november 2017 10:59
Bill, I modelled your antenna for a 20 meter high vertical with 4 X 10 meter (25 feet is too short) long sloping topload wires. All 2mm. The radiation resistance was about 14 ohm when resonant (no J)
It depends not only on distance. Also the gain of both (TX- and RX) antennas matters. The lower the gain of the RX antenna, the more the re-radiating TX antenna (or other nearby wires/towers) will mo
Thanks for the info Tree. Sad to hear that Coby past away. Bob and Coby visiting PE5T in 2004. They went to the Netherlands allmost every year, visiting the islands, close to my qth. Kees, PE5T Verzo
What is away. If only a few meters it will not work. My inverted L still influences the beverage that runs away from it and starts 40 meter from its base. Best thing to do is to detune the TX antenna
For more then 10 years I use 170 meter long runs of 300 Ohm from www.dx-wire.de. Very small size and very strong. Pe5t Verzonden vanuit Mail voor Windows 10 Van: John Kaufmann via Topband Verzonden:
To obtain 40 dB cancellation, the maximum amplitude difference between the signals is 1% and the maximum phase difference is 8 degrees. Verzonden vanuit Mail voor Windows 10 Van: Richard (Rick) Karlq
If you have a quater wave vertical resonating on 1,9 Mhz, the swr 1:2 bandwith will be > 200 kHz. Even if your feedline has 3 dB attenuation (that is a lot on this band), the additional loss will be
Such a cable has practical no attenuation on 160 meter. You can simply do all the tuning in the shack. Verzonden vanuit Mail voor Windows 10 Van: Ron WV4P Verzonden: zaterdag 16 mei 2020 23:46 Aan: R
Nothing wrong with conditions. Yesterday afternoon I worked K9FD in Hawaii and this morning the west coast and WL7SJ. Good propagation to Japan also. Kees, PE5T Verzonden vanuit Mail voor Windows 10
