| Power Level Abbreviations and logging | WD8DSB | on 25/2/17 |
| Simplest is to log it as indicated in the rules, using any shortcuts to indicate power. That's how I've done it, going back to BC (Before Computers). | ||
| Converting a 80M dipole to 160M ? | hamwillyt | on 9/2/17 |
| Another trick is to drive your 80m dipole as a vertical with a "top hat" on 160m. By shorting the feedline at the bottom, you are now driving it against ground (it is now a vertical antenna). You now need a good radial system. If the feedline is close to one quarter wavelength on 80m, the overall length on 160m is about one quarter wavelength, and easily tuned. I did exactly that w/ my 80m cage inverted vee. My feedline is about 85', and the ATU built into my Kenwood TS850SAT easily tunes it on 160m. I use a SPDT vacuum relay to do the switching at my ground bus outside the shack. Photos & text are on my Flickr page: http://www.tinyurl.com/wa7prc-80m-160m vy 73, Bryan WA7PRC |
