Couple loggings above 500kc
« on: November 24, 2013, 0416 UTC »

Just listened for a short while above 500kc tonight...

02:29utc  HRD 524kc  Kountze, Texas

02:40utc  HMY 512kc  Lexington, Oklahoma

Placed my homebrew 700 cycle audio filter inline for the first time in years.

I made it using only tuned L-C circuits and a single FET amp about 25 years ago. It's a real oddball design, but it sure has a very sharp peak at 700cycles. Nice for digging out weak cw.
