Polyester and many other types of rope are quite stretchy -- and some loose weaves are horrible in this regard. With the long lengths involved, it is quite easy for the combination of sag in the guy
Hi everyone -- Just got home last night from 3B9C and back on the reflector. I had a chance to read some of the postings here while at Rodrigues and the information was helpful/encouraging to G3SED,
Hi Chet -- That was me at the key the night W4TEA made his QSO. We have had a series of USA openings with either heavy QRN or just very marginal, weak propagation of signals back from North America t
I don't think we worked anything on 160m that was "long path" (by which I mean a great circle route of over 20,000 km) while at 3B9C. I feel pretty certain we did work some skew path, but can't prove
Many years ago W8LRL gave a presentation at a PVRC meeting about 160m DXing. He had a histogram showing the number of NEW countries he worked in each calendar month over the years. The histogram was
Hi everyone -- I am examining propagation on 160m from 3B9 and need to confirm a few QTHs. Unfortunately I don't have email addresses for everyone. Can anyone help with the following: W6UD AA6VQ Than
(At the risk of adding gasoline to the fire...) I wanted to highlight a distinction that Tom W8JI made in an earlier post. Tom mentioned that, while using two phase-locked receivers attached to separ
Hi everyone -- I am working on a little (tedious) project of adding latitude/longitude to North American contacts in the 3B9C 160m logs, in preparation for some analysis. Some callsign lookup service
In answer to some questions from Bill W4ZV about 3B9C results on 160m to North America: total 160m QSOs: 2288 NA QSOs: 563 USA (48 states): 537 Canada: 24 (sadly, none west of VE3). Virgin Islands: 2
Someone asked how many unique calls are in the list of North America QSOs with 3B9c on 160m. A manual count of duplicates reveals: ... of 563 North America QSOs... ... 22 QSOs were for a second mode.
At 3B9C it took us about 15 days to work 86 countries on 160m. I suspect a motivated topband team on a major DXpedition could work 100 countries if they were lucky with propagation and local receivin
Hi Tony -- EZNEC 3 is not capable of modeling radials at 3-inches above ground. A 3-inch separation between ground and radial is below 0.001 wavelength at 160m. Even with NEC4 one should avoid modeli
Hi everyone -- I am one of the members of the upcoming 3Y0X Peter 1st DXpedition (see www.peterone.com for details). I hope to work lots of you on 160. I expect to have to fight my way to the radio a
Hi everyone -- After the 3B9C DXpedition earlier this year, Eric K3NA built some animated views of interesting 160m openings to North America. These have been shown during presentations at Dayton, Ha
At 3B9C we worked stations as far as 1000 km past the terminator into the daylight (afternoon) sector on lengthy paths (possibly skewed). Depending on latitude and season, that can be anywhere from 2
Hello everyone -- In preparation for the Peter 1st DXpedtion's 160m propagation study, please help us beta test our website at www.dxmap.com/160m. A description of the study, and how to use the websi
Hi everyone -- As some of you know, a special data collection project to help study 160m propagation was prepared for the 3Y0X trip. The 160m propagation project team has now modified this tool for y
Hi everyone -- First, thank you to the many stations who have registered at www.dxmap.com to submit 160m reception reports for the Kerguelen DXpedition. Naturally, one expects most 160m operators to
The 160m signal reporting website at www.dxmap.com has been improved! You can now submit reports later (not in real time). Just click on the bright blue "date/time" at the top of the report form and
Hi everyone -- Friday evening saw over 100 reception reports recorded for Kerguelen 160m signals on www.dxmap.com. Many thanks especially to OH2BO, LA7THA, LA0CX, IV3PRK, and OK1RD, among others, who
