There are a number of Emergency Services packet radio kits amoungst the members and I've found a couple of easy setting changes to make it work much better.
The first one is a setting on the KPC-3+ called CD.?
With the KPC-3+ in command mode (not connected to another station) type cd and press enter.
The default setting will return INTERNAL. This means the TNC will not transmit over ANY noise heard on the receive.
We want to set it to SOFTWARE.
Type cd soft and press enter. It will answer CD was INTERNAL. Type cd then press enter.?
It should answer SOFTWARE.?
This means the TNC will look for packet data in the noise and only prevent a transmission if it senses another packet station on frequency.
Another issue we have run into involves KPC-3+ users who use Putty terminal program on their packet radio computer to "talk" to it.
The default Putty keyboard setting for Backspace needs to be changed.
As is, when you backspace to edit, the deleted text along with a tiny square for each character deleted gets sent.
The worst part is the sender has no idea. The sentence on the receive end is often unreadable because of this.
The fix is simple.
Under the Putty setting tree, select Terminal then The Backspace Key.
Select Control-H
Save your settings to Default Settings or it will default back to Control-127 the next time you open it.
Hope to see more of you on Chat Room - QBCHAT.
