 The Scout is a terrific transceiver,​ but it drifts, despite the frequency compensation driven '​CPU'​ circuitry. It will drift upwards over time or upwards faster if the transmitter is used and its left on a fixed frequency for extended periods. The FLS will attempt to keep the radio '​LOCKED'​ until it drifts so much it runs out of compensation. You don't notice this unless you leave the Scout on a fixed frequency for an hour or more. You can tell when its goes into an out of lock state under these conditions because the '​unlock'​ LED will light up. If you turn the Scout off and then on again, you'll see that the frequency display is higher by about 600 cycles or more. The Scout is a terrific transceiver,​ but it drifts, despite the frequency compensation driven '​CPU'​ circuitry.
