Re: Topband: 160m activity and propagation

Hello Bob, I have no experience from the last solar minimum, but I heard plenty of stories! I was really looking forward to this minimum to see the improvements in 160 propagation. I was hoping to knock off some countries in deep Asia. (Yeah, right!) So far I am not impressed. That being

Topband: 160m activity and propagation

Greeting all, This season has been interesting not because of highlights but because of a noticeable change in propagation at least from my Arizona QTH. I will note from my perspective highlights have been few. Yesterday Dave W0FLS was holding court calling CQ. I could just barely hear the

Topband: Wednesday activity nite.

Hello Roger & topbanders, I took a nap in the early evening, then was out on 160 a bit after 0300 UT. Activity was steady and the QRN level was pretty low. The QSB was in evidence, as usual, but I thought condx were pretty nice. I worked 56 stations in between making a sliding shelf for my

Re: Topband: 160m activity and propagation

Hey Bob, I found the season typical though signals in general were down from this part of the cycle. I did work 128 European stations in the CQ 160 which is a personal best for me. There were many nights when I had the EU RBN lit up with huge reports but no answers to many CQ's. I blame that on

Topband: New RFI Source

As mentioned earlier, last night I noted a drifting birdie sweeping up and down the 160 meter band.  Hans, SM6CVX, wrote to suggest a switched mode power supply was the culprit. To make a long story short, I recently installed one of these to archive some VHS tapes:

Re: Topband: -: Dacron & varmits

Folks, Thank you so much for the many replies. I now have several sources and I'm going to take a photo of a piece of the cut end of what I am already happy with and send it to the sellers. Unfortunately I cannot get pullys up to run ropes through, or for that matter the antenna, should I

Topband: 160m activity and propagation

Perhaps I was misunderstood by some in their comments regarding my post. As Larry N7DD pointed out the stations are there at least in the contests. My comments were pointed at changing propagation characteristics. It is no uncommon for huge swings between my location, N7DD near Tucson and

Topband: New RFI Source

Another drifting source that slowly drifts across 80 meters and repeats turns out to be a "Solar Boy" one of the cheap garden ":Little Boy" with LED lights at night . For several days I thought it was my active vertical amp oscillating -then went snooping with my Icom R10 rx and lo and behold

Topband: shunt fed tower (Versatower BP60 / Westtower)

Hey, does one of you use a  BP60 Versatower  or Westtower (18m) as shunt fed for 160m?I have some questions about tuning 73  Andy DL8LAS www.dl8las.com www.swing-company-bigband.de/ www.uni-big-band-kiel.de/ _ Searchable Archives: http://www.contesting.com/_topband -
