NOTICE !
I've placed the interface drawings, diagrams, and schematics on these web pages to help HAMs enjoy the hobby as I do. You may build or order most all devices or parts to construct your own interface, be it Packet TNC to radio, or Sound Card to transceiver. I try to maintain a full line of parts, cables, and connectors for all Amateur transceivers, both accessory jacks, microphone jacks, and RF connections. My goal is to provide these components, connectors, and devices at a fair price, and at the same time, deliver them as if I were the anxious customer. G. E. Rogers Sr d/b/a BUX CommCoClick Here, to Email BucK4ABT,

Packet Radio's most complete TNC to Radio diagrams, and illustrations on the worldwide internet. These pages are intended to support the Packet Radio users and the AX.25 digital Amateur Radio Operator. I've spent many long hours and I continue to research the latest Amateur transceiver input and output connections to insure that most, if not all, these interface drawings are correct. Please use caution as you interface your TNC and transceiver. The caveat is; "I am not responsible for mistakes or omissions." It is my wish that this reference material is helpful to all who use it and that it promotes a greater interest in this fun-filled hobby of PacketRadio.
Happy Packeting, es 73 de Glynn E. "Buck" Rogers Sr. K4ABT
NOTICE: Read the following as the information may prove helpful later.
The mic and TNC connections pictured on these pages illustrate the connections you will encounter with most radio to TNC interfaces. Most manufacturers will apply the same pin connection scheme to their radios when using the same type mic (number of pins) connector. For instance, most all models of ALINCO transceivers which have 8 pin Mic connectors will use the same pin connections; e.g. Pin 1 = AFSK IN, Pin 2 = PTT, Pin 8 = Ground for PTT, and Pin 7 = Shield. Receive audio is usually taken from the External speaker (in most transceivers, a 3.5 millimeter plug).
One very important reminder; For best TNC DCD performance, your transceiver volume should be set between the 9 and 11 o'clock position. I've found that too little audio (below the 9:00 O'clock setting), is not good. Likewise, too much receive audio will create distortion and will cause inconsistent decoding of Packet data. Knowing this, we soon understand that an optimum setting for the volume control is at the ten o'clock position. The Squelch may be set in a similar manner, usually aroung 10 or 11 o'clock position... unless you have local CPU noise, whereas, you have to govern your settings accordingly.
The burden is on the user to purchase the correct connector for the transceiver and computer to be used with the TNC. Determine the kind of microphone, speaker jack, and computer serial comport connectors that you're going to use.

Shown here is a typical microphone I/O employed on many pre-1997 VHF transceivers. This drawing is shown for reference only. The numbers identified on the MIC connector are to help the user to identify the pin numbering sequence of a typical eight (8) pin mic connector.
