Tuning your antenna using the PC78LTX Radio:
Turn the radio on.
Set to Channel 40.
Flip switch to CAL for calibration.
Press and hold mic button.
Adjust the SWR CAL dial until meter swings right and sits directly under "CAL" on the meter.
Keeping the mic button depressed, switch the SWR toggle back to SWR and write down the SWR reading on the meter.
Repeat the steps above on Channel 1.
Use your SWR readings to make adjustments to your antenna accordingly.
If channel 40 SWR is higher than channel 1 SWR, lower/shorten the antenna. If channel 1 SWR is higher than channel 40, lengthen/extend the antenna. The goal is to have the reading be similar and both be under 2 or lower (ideally).
