SignaLink Jumper Settings & Cable Wiring Diagram
For HTs with a Combination Mic / PTT Line
The diagram shown below is for a typical HT with a
combination Mic/PTT line. Your radio
may require different connections from those shown. Check
your radio manual before installing the jumpers or building your radio
cable, and be sure to read "IMPORTANT NOTES" below!
Yaesu users: The diagram
shown below works great with Yaesu's CT-91 adapter (fits VX-120, VX-170, VX-127,
VX-177, VX-6R, VX-7R, etc.). However, you need to use **mono**
plugs instead of stereo.
R1 should be a 2.7K 1/4 watt resistor
be a .1uf non-polarized capacitor
prevent damage to socket JP1, the diameter of R1 and C1's leads MUST be
the same diameter as our jumper wires (24 gauge)
Your radio manual may show different values
for R1 and C1. The values given here have been used successfully
with virtually every radio available, and should work fine.
The wire color code shown is for our un-terminated radio
cable p/n "SLCABNC".
