What you have (if you can generate enough voltage - it will take about 35-40W of transmit power) is an emergency flasher weakly lighting the alternate LEDs at an HF rate. This is with Red LEDs, as I offered in another posting, if you tried with Blue LEDs, you would need more like 170W to weakly light them. The 100K is literally useless (as are the 1N914s), and the 1K is a severe handicap. Once you get past those limitations you will have a brighter flasher at no big hit to the overall efficiency - if a flasher is what you want. Mad Man Muntz with his dikes would have a glorious time trimming back the excess here. It might sell well to the CB crowd that wants 27 MHz strobing brake lights. Could even perform better for night time DX than some rear mounted bumper whips. Perhaps a better use of their linears - as legal power won't light this circuit. 73's Richard Clark, KB7QHC |
