The microprocessor runs a fine tune routine just after the tuner finds a match at an SWR of 1.5 or
less. This routine tries to get the SWR as low as possible (not just 1.5); it takes about a half
second to run. There is also a quick tune mode. If the SWR is below 2.0 when you press the tune
button to start a tuning cycle, the tuner will first try a memory tune routine to see if it can achieve
a low SWR without a complete re-tune. This also takes about a half second to run. If it does not
find a good match, then it runs a full tuning routine.
A Word About Tuning Etiquette
Be sure to use a vacant frequency to tune. With today’s crowded ham bands, this is often difficult.
However, do your best to avoid interfering with other hams as you tune. Your OT-11P’s very
short tuning cycle, often only a fraction of a second, minimizes the impact of your tuning
transmissions. Tune at reduced power whenever possible; one or two watts is plenty.
Care and Maintenance
Your OT-11P tuner is maintenance-free. As with any modern electronic device, your OT-11P can
be damaged by temperature extremes, water, impact or static discharge. LDG strongly
recommends that you use a good quality, properly installed lightning arrestor in the antenna lead.
