The first local osc outputs a frequency of 45 to 75 mhz (45 mhz higher than the operating frequency) in 2.5 khz steps depending on the operating frequency. This frequency is controlled by the onboard

Hi Carl, Thanks greatly for your response!! I wonder if I could monitor the op frequency anywhere inside then? I'm still toying with the idea of controling an external tunner with a PIC circuit. I us

The AT-200PC autotuner from LDG, when used in conjunction with my rig control software, ends up following the rig without having to transmit. You just have to tune one time on each frequency and then

Thanks Carl, I already have the tuner, and the pic to control it, just investigating a way to get frequency info to the pic direct from the Jupiter. I've seen screen-shots of your software! Extremely

If you are going to do it with a Pic then it seems trivial. Use the first LO (you may need to buffer it) Count the freq 45-75 MHz in 2.5KHz steps Have the Pic subtract the 45MHz offset Tune the tuner
