But... I have been chasing my tail on 160M. The calculated C1 / L / C2 values at 1.9 MHz are 298pF / 25.47 uH / 1708 pF. Actual values are 276 pF / 25.53 uH / 600 pF. Efficiency is off to 48%. The loading area is where to look first...C2 should be 1500-2000 pf when you are tuned up. (((73))) Phil, K5PC |
