Zazzle,
I'm always glad to hear about 11 meter band beacon projects. I will want to put one of my own up (some day...) with similar power output and antenna type (vertical, simple 1/4 wave or something like that) but on the 27 MHz side, instead of 26 MHz. Although, I have to say I have an increased appreciation for your frequency choice. While there is/was some minor Russian taxicab QRM in FM mode, the frequency is a good one. When the band is open, the "high band" channels (27.405-27.995 MHz) are almost all busy. Luckily for me, here in the USA, using a frequency that ends in 0 (for example, 27.670 instead of 27.675) will likely help me out. With the Russians, who use 5 kHz steps on 11 meters, that can't really be avoided.
Either way, good work and keep it up! I will keep checking 26.510 MHz / 26510 kHz for your beacon in the future.
