When the radio detects the correct tone, it will halt on that tone, and audio will be allowed to pass. (TCH) key for one second; the CTCSS tone detected 4. Press and hold in the will be stored as the "current" tone, so it may be used for memory storage purposes, and you may now exit to normal operation. FT-8500Operating Manual 35 TRANSMITTER OPERATION FM TRANSMISSION DCS Operation Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more advanced tone system that is less susceptible to false triggering than CTCSS. A DCS Encoder/Decoder is built into your transceiver, and operation is very similar to that described above for CTCSS. Set the desired DCS code via Menu #23 (DCS CODE). Press the key momentarily, then rotate the knob, as needed, until Operating Function Row 4 [RPT, REV, TON] appears on the display. (TON) key three times to activate the DCS Encoder/Decoder (the " 3. Press the " icon will appear on the display). Before beginning Digital operation, you need to define which Digital mode will be utilized. To do this, use Menu #26 as follows (in this example, we will set up RTTY as the Digital mode): 1. key for one second to enter the Menu mode. Press and hold in the Rotate the knob to select Menu #26 (DIG MODE). Rotate the knob to select "RTTY. " Press and hold in the key for one second to save the new setting and exit. Use this technique to set up any digital mode. RTTY (Radio TeleType) Operation The "RTTY" mode on the FT-8500is based on LSB-side carrier injection, in accordance with long-standing amateur practice. If you need USB-side injection for your application, see the "User" mode discussion below. Connect your TNC (Terminal Node Controller) or terminal modem to the FT-8500's rear-panel DATA jack, per the illustration. Press the / key, as needed, to select the DIG mode (the "DIG" icon will appear on the display). Be certain to use the "TX Audio" line from your TNC, not an "FSK Key" line, for the transmit-data connection. Press the / key, as needed, to select the DIG mode (the "DIG" icon will appear on the display). You should now be able to tune around the band, and any RTTY signals heard should be capable of being decoded.

Again press the key momentarily, and rotate the knob one click clockwise to re(MW) key momentarily; select Operating Function Row 2 [MW, MC, TAG]. Press the the "M-001" indicator will flash; press and hold in the microphone's PTT key, and while (MW) key until you hear the double beep. You have now stored holding it in press the the uplink (earth station transmitting) frequency into the same memory register as we did previously for the downlink frequency. [. . . ]
