A Cable Construction Trick

I have several TNCs and several radios, and sometimes "mix-and-match" them. The problem is that I didn't want to make a unique cable for each radio/TNC combination. Instead I made just one cable for each radio which terminates in a male DB9 connector. And I made just one cable for each TNC which terminates in a female DB9.

Then, depending on which radio and TNC combination I want to use, I plug the DB9 connectors together.

The key is to establish a common wiring plan for the DB9 connectors, something like:

Radios

TX audio pin--> male DB9  pin 1
PTT pin---------> male DB9  pin 2
RX audio pin--> male DB9  pin 3
Ground pin----> male DB9  pin 5

TNC or Sound Card

1 pin  DB9 female <--- TX audio pin
2 pin  DB9 female <--- PTT pin
3 pin  DB9 female <--- RX audio pin
5 pin  DB9 female <--- Ground pin 

For my packet sound card cables, I just adopted the TNC (DB9 female) scheme. I can now plug my sound card cables into any of my radio cables and run sound card packet on my mobile, base VHF, base HF or portable rigs! I don't need to build a separate sound card interface for each radio...just a separate radio connector.
