Thanks again Tomas,,,,I thought it was but I wanted to check first before I went connecting anything. I haven't started my 'IRSL' yet,,,I may do it now as a Winter project. I've made several new pairs of coils lately and I seem to be getting a lot 'neater' at them and according to my LC Meter they seem to be up to specs. I just have a lot of practise ahead of me now to become better at tuning them. My TX Coil is 14.75MH and the frequency is 8.35KHZ,,My RX coil is 14.75MH and the frequency is 10.80KHZ with the onboard 14.7nf capacitors,,,If I add 1.25NF to the RX coil to give 10.36KHZ would that be correct?,,,,Thanks again Tomas,,,Regards,,,MartyComment
