Please forget my mistake, R.res calculated should read 0.02 ohms. If we take your estimated Rad.pwr of 23.2 mW and increase it by 8db (x6.31) this gives 146.4mW which is not too far from my estimated 125mW.The d >ifference ,assuming Ko's figure is correct, is either your ERP is a bit down on your Rad.pwr which seems most likely,or my 125mW ERP should be a bit higher.I am assuming the same local losses as on 136 in calculating this figure.I hav'nt been out to check > it yet. Either way they tie up quite well in the imperfect world we operate in,and thanks Ko for the comparison. 73s Laurie. > Peter, Laurie.. For 73 i used,- Antenna: Chelcom Hf-v1.
