Construction
The FSK9601 is intendedfor use with the TNC3S or TNC31 Packet-Radio Controller. Dimensions: 120x40 mm.The modem is connected to the TNC with a 20 pin flat ribbon cable. The trimmerfor output voltage can be accessed through a window on the TNC3 rear panel. Theradio transceiver is connected via a 5 pin standard DIN plug.

Data
The FSK9601 is a FSK-modemwhich receives and transmits data according the G3RUH-standard. It produces aband-limited data signal with 9600 baud data rate and can be modified to otherspeeds from 4800 up to 614k Baud by changeing some components and jumpers.

The FSK9601 transmitfilter and receiver design was developed by Ulf Kumm, DK9SJ. The scramblingalgorithm is compatible with the G3RUH standard, the PGA design was derived froma design of DF9IC.
Model 9601 Radio Instructions Diagram
power supply: 5 V approx. 120 mA from the TNC |
muting: the transmitter is muted when receiving. |
PTT-watchdog: contunuous transmit time is limited to approx. 20 sec (may be disabled by a jumper) |
bit-error-test jumper: a constant '1' may be transmitted when the according jumper is closed. |
transmit jumper: for tests, the modem may be set to continuous transmit mode by a jumper. |
high impedance input (100 kOhm // 100pF) 50 - 500 mV input voltage required. |
output voltage adjustable 10 mV to 3 V, 2 kOhm series resistance, DC-decoupled. |
3 test points for TX, RX and PTT |
input voltage limiter prevents overdrive due to changes of the dc voltage across the input when switching from transmit to receive mode |
FIR-filter programmed for FSK (cos-rolloff characteristics) and GMSK filter response. 128-tap FIR-filter with 128 taps (16-fold oversampling x 8 bit length). The digital filter produces a minimum of distortions and harmonics. |
flexible baudrate: the board is designed for a variety of transmit and receive baudrates, ranging from 4800, 9600, 19200, 38400, 76800, 153600, 307200 up to 614400 Baud FSK. Transmit and receive baudrate can be selected different, e.g. for satellite use with 9600 Baud uplink and 38400 baud downlink. |
suited for full duplex (simultaneous transmit and receive) |
