When I was a teenager chasing Gus Browning on 40 meters I caught a tree on fire at night because the end of my dipole was in some dead tree branches! My parents were not happy... 73 Frank W3LPL -- Or
I worked and received a QSL from Jackie for a Topband QSO on 13 Nov 1987. A long time ago! 73 Frank W3LPL -- Original Message -- You did not say exactly how many years ago you worked Jacky on 160. In
Forwarded from W0YR: The FCC is going forward with its plan to allow the r.f. noise floor to rise to unprecedented levels which will, of course adversely affect our hobby. Another effect is to eventu
Hi Tim, This is the patent for the classic Edgar F. Johnson (E.F. Johnson) transposition insulator: http://reference.insulators.info/patents/patents/pdf/4/us002043754-001.pdf http://www.google.com/pa
This is an example of a fishnet buoy that operates from 1.6 to 4 MHz. http://www.blueoceantackle.com/radio_buoys.htm The good news is they're battery operated and will ultimately have to be retrieved

Hi Pete, I wonder why you've decided to switch to BNCs? They have their own issues and they've completely unsuitable for outdoor use. I wonder if perhaps you've been using poor quality F connectors?
Hi Pete, You can use your MFJ 259 to measure loss through your bias-T setup. 100 microhenries should be adequate; however, a properly designed bias-T should always have two inductors at the injection
There may be some interest among topbanders in this NPRM attempting to revitalize our neighboring spectrum user. http://media.npr.org/assets/news/2013/fcc.pdf 73 Frank W3LPL _________________ Topband
A noise canceller such as the DX Engineering NCC-1 is an excellent solution to RFI from a adjoining neighbor's house, such a plasma TV or switching power supply RFI. Ideally, install a simple antenna
Hi Mike , Thanks for sharing that video. Crystal controlled QRP from the west coast is quite a challenge! Have you thought about doing something about that headphone cord under your arm? tks 73 Frank
Large guy insulators may pass two turns of your Phillystran. They're always available on ebay for reasonable prices. If it would help, I have several guy insulators with one inch diameter holes that
Another alternative is to wrap two turns of the Phillystran around a short length of three inch diameter steel pipe or tubing. Then pass a large shackle through the tubing to fasten it to the steel c
Hi Doug, A few notes about the short verticals in my 160M passive receive array. I use them in my W8JI broadside-endfire passive array described in detail on Tom's home page and on W5ZN's home page.
At the speeds that deer run across an open field, I doubt that repellant will help. Seven foot fence posts work perfectly, and they will last a lifetime! 73 Frank W3LPL -- Original Message -- A possi
Hi Jon, I've also found that my four phased short verticals consistently outperform my Beverages, especially when arrival angles are low. Sometimes I can copy signals on the phased averticals that I
