It's about 800 Hz (not 1200 or 2200) but it is a steady tone at essentially the same level as the other tones. You can transmit this tone by simply manually keying the radio that the TNC is attached to.

Is there a way to SEND the 2200 and 1200 hz tones individually on a KISS TNC?<br>

Consider the following approach.<br>
<br>
(1) Put your TNC into normal operation so that it will transmit<br>
occasionally.<br>
<br>
(2) Set up a receive-only instance of direwolf using a different receiver<br>
and a good antenna.<br>
<br>
(3) Observe the audio level lines for stations heard directly.<br>
<br>
<br>
Example:<br>
<br>
<br>
$ direwolf -t 0 | grep -v "^Digipeater" | grep -A 2 "audio level ="<br>

(4) Notice how the audio levels vary all over the place. 32 to 99 and<br>
everywhere in between.<br>
<br>
Kenwood and Yaesu fall near the middle, 75 to 82. Assuming these have the<br>
factory settings, that level should be close to ideal. If you don't see any<br>
of them, just take the average of the crowd.<br>
<br>
(5) Adjust your transmitter to have a similar level.<br>

Exercise for the reader:<br>

(a) What is the impact of setting the transmit volume level too high?<br>
<br>
(b) What are the other two numbers and the vertical bars after the audio<br>
level?<br>
