Time to start looking at levels and audio purity. For you, and
anyone else on the list without a hardware CRO, download and
install Visual Analyser 2011, a complete set of audio tools in one
software package.<br>

Things I would check .....<br>
1. Is the comport speed set correctly to match the settings
in the application. e.g. 9600<span style="color:#1F497D"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">>>Yes,
all correct there..<o:p></o:p></span></p>
<p class="MsoNormal"><br>
2. Is the radio data rate set correctly to 1200bps - DIP
switches 6, 7, 8.<span style="color:#1F497D"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">>>Yes
all correct there..<o:p></o:p></span></p>
<p class="MsoNormal"><br>
3. Is the HF/VHF switch in the out position for VHF<span
style="color:windowtext"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">>>Yes
set to VHF<o:p></o:p></span></p>
<p class="MsoNormal"><br>
<br>
Going a little deeper, I'd check the audio into the TNC from
the radio to see how close the two tones are to being the
same level. The Exar decoder chip in the MFJ1270B is
particularly intolerant of the high tone (2200Hz) being
lower in level than the low tone (1200Hz) and will refuse to
decode if the levels are too different. The TNCs need about
200mV p2p for reliable decoding.<span
style="color:windowtext"><o:p></o:p></span></p>
<p class="MsoNormal"><br>
<br>
Have you used a terminal program to try to talk to the TNC.
You should, at very least, see the TNC message when the TNC
is powered up. This can confirm comport speed, etc. I don't
know what the latest terminal program is for Windows (I use
Linux) but hunt around. If you can talk to the TNC with the
terminal program you are well placed to conduct various
tests as suggested by Gordon vk4vp.<span
style="color:windowtext"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">>>Yes,
used PuttyTel and connected and I can communicate to the
TNC.<o:p></o:p></span></p>
<p class="MsoNormal"><br>
<br>
I have 8 MFJ1270B TNCs (all bought second hand) that have
seen service at HF, VHF and UHF and I must say I've never
had a reason to doubt the tone frequencies on any of them,
but ........<span style="color:windowtext"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">>>Hmm,
used to work perfect, but has been packed away…<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">Thanks for
your help <o:p></o:p></span></p>
