Icom using analog band data. Here we use the radio’s analog band output for band information.
Control and data transfers are not available. Some Icom radios have shown a tendency for the
band output to drift with increased transmit output power. For this reason it is recommended that
the reference input setup be used. In this configuration, the band data is connected to pin 9 and the
8 volt reference is connected to pin 4. This mode is set with jumpers W1, W2 and W3 installed.

Yaesu FT817 using analog band data. Band is determined from the radio’s analog voltage
output. Control and data transfers are not available

W1, W3 W2, W6, W7, W8
W14, W17 W9–W13, W15, W16, W18-W23
Computer parallel printer port. BCDband information is communicated using the parallel data
available from some computer’s parallel port or parallel BCD data from some radios. Control and
data transfers are not available
• Parallel PCB information
Installed Removed
W2 W1, W3, W6, W7, W8
W9–W23
For all analog inputs, use J1 or J2 (same connector as the analog input), pin 1 for ground
connection.
