I used a broadcast station on 620 kc for ARGO frequency calibration. I'm using a Yaesu FT-990 so can't tune under 100 kc for WWVB. I had to use and actual offset of 650 hz VS 700 hz to make the 620 kc carrier at exactly 700 hz on the top horizontal scale. Now I presume I should find RU6LA sending QRSS60 on 135921.8 Hz, somewhere around 700 hz on the top horizontal scale?! Or place 135921.8 kz minus 650 hz equals 135921.15 kc in the offset box under calibration then RU6LA should show up near 135921.15 khz on the top horizontal scale. Correct? If he is using 60 dots/secs should I set it at 60 or something higher like 120 dot/secs for bettere reception? 73, Thomas Giella, KN4LF Plant City, FL ----- Original Message ----- From: "Alberto di Bene" To: Sent: Friday, December 27, 2002 12:35 PM Subject: Re: LF: Re: ZL6QH test Dec27 > Thomas Giella, KN4LF wrote: > > > I must have done my frequency scale calibration wrong as I received > >nothing here.
