Thanks Bob: http://n4hy.org/10MeterBottom.png <-corrected link Since they are all into a dummy load it looks like the NF of the radio degrades about 5 dB from 14 MHz to 28 MHz and about another 5 dB from 28 MHz to 50 MHz. Is that a safe assumption? 73 Phil N8VB _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/
