Re: Frequency calibration
toggle quoted messageShow quoted text
You want to be sure that the CAL jumper is already in place when you apply power.
After 5 seconds of RF output, the RF output will disappear and you restart that process. As you do, the frequency will start up ever closer to your target frequency of 7030.00
When you're at the target, remove the CAL jumper and cycle power once more for normal operation. Any mismatch in sidetone pitch between the Hilltopper and a second rig means the trimmer cap needs adjusting.
Hope this helps - 73, Dave- K1SWL

I just finished a Hilltopper 40. It works well, but I'm a little fuzzy on the frequency calibration.
