But i can see it indirectly from the antenna current plot which is generated from the TX PC, which is available. The first symbols are out now. My 5th coil is completed. DC resistance is 270 Ohm, from a single bucket. I made a quick test here in the office. I took the coil arrangement that was used on 5170 Hz and tuned it to 5170 Hz again with a fixed capacitor in series with a varaible capacitor. Then i exchanged the upper coil, removed the one which just 30% wound by the new one which is now 100% wound. Then i tuned the function generator to the new resonance frequency: 4530 Hz!! That's just 60 Hz distant from the next target frequency. But the coil has a relatively low Q so i think it will work... 73, Stefan
