Page 43: Packet 1200/9600 Bps Fm Operation
1200/9600 ACKET The FT-817 is designed for operation on either 1200 bps or 9600 bps packet, and setup is similar to that described previously for SSB-based modes. A separate Data input adjustment is provided, allowing you to optimize the deviation on the FM Packet modes separately from the SSB-based Digital modes.
Page 44: Am Transmission
RANSMITTER The FT-817 utilizes low-level amplitude modulation of an early stage for transmission purposes. This capability is primarily provided for emergency use only, as low-power op- eration typically utilizes more efficient transmission/reception modes. The AM carrier level is preset to 1.5 Watts during alignment at the factory, and should not require further adjustment.
Page 45: Time-Out Timer
Most often used on FM, the transmitter’s Time-Out Timer (TOT) feature disables the trans- mitter after a user-defined period of transmission. This feature may be useful in preventing a “stuck microphone” (accidental closure of the PTT switch) from causing interference to other users, and it will also force you to keep your transmission short, thereby conserving battery power.

MART The Smart Search feature automatically stores frequencies where activity is encountered on the current band. When Smart Search above your current frequency, storing active frequencies as it goes (without stopping on them even momentarily). These frequencies are stored in a special Smart Search bank, consisting of 50 memories.
Page 54: Scanning Operation
CANNING This transceiver contains a wide variety of scanning capabilities. Whether you are in the VFO mode or one of the memory modes, scanning operation is fundamentally identical in all configurations, but with the following differences: In the VFO mode, scanning causes the transceiver to sweep up or down the band, pausing or halting on any signal encountered;...
Page 55 Scan Skip Programming (Memory Mode Only) Among the memories you have programmed, there may be some stations which you do not wish to scan. For example, broadcast signals (which are transmitted continuously) will cause the scanner to stop, and such channels may be skipped so as to avoid this inconvenience. To remove a channel from the scanning loop: 1.
Page 56: Programmable Memory Scan (Pms) Operation
CANNING Programmable Memory Scan (PMS) Operation To limit scanning (or tuning) within a particular frequency range, you can use the Program- mable Memory Scanning (PMS) feature, which utilizes special-purpose memory pair (“M- PL” and “M-PU”). The PMS feature is especially useful in helping you to observe any oper- ating sub-band limits which apply to your Amateur license class.
Page 57 CANNING PERATION Note The frequency resolution for these sub-band limits is 100 kHz, although the channel resolution of the sub-band limit memories in whatever you have selected as the cur- rent step size. As a result, the frequencies stored in these special memories (M-PL and M-PU) are both rounded down to the nearest 100 kHz for their roles as sub-band limits.
Page 58: Dual Watch Operation
ATCH Dual Watch is similar, in some respects, to scanning. In Dual Watch, however, the trans- ceiver monitors (squelched) on the VFO-A frequency while periodically checking VFO-B for activity (or vice-versa). A typical example might be for you to set VFO-A to 50.110 MHz, watching for DX stations who might call CQ on that frequency, while periodically checking 28.885 MHz for stations reporting band openings on 6 meters.
