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.

 

 

 

IMPORTANT NOTES

  • R1 should be a 2.7K 1/4 watt resistor

  • C1 should be a .1uf non-polarized capacitor

  • To 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".
