+=== Direwolf update : 10/04/24 ===
+  * Direwolf v1.6 in Debian has a minor annoyance - it decodes its own transmitted frames occasionally due to cross talk in the sound card
+  * This is reported to be //fixed in 1.7 release// so I cloned the git repository and built the current 1.7 version
+  * It has removed the annoyance of seeing (and reporting to APRS-IS) your own transmitted packets
+  * There are other changes and improvements which I will investigate over time.
+  * Steps to clone/build
+<code bash>
+sudo apt-get install libavahi-client-dev
+git clone https://www.github.com/wb2osz/direwolf
+cd direwolf
+mkdir build && cd build
+cmake ..
+make -j4
+</code>
+Running the new version
+<code bash>
+cd src
+./direwolf -c ~/direwolf.conf
+</code>
+A few red warnings due to changes for v1.7 not being fully compatible with the previous config options, but it runs and doesn't seem to decode its own transmissions any more.
+A few tweaks to the config:
+<code bash>
+ADEVICE  plughw:2,0
+CHANNEL 0
+MYCALL GM4SLV-10
+#MODEM 300 7@30

+</code>
+  * I will remove the Debian version 1.6 and ''sudo make install'' the newly compiled v1.7 once I'm happy with it.
+  * This version also decodes FX25 packets - which I don't fully understand yet
+<code>
+SP6PGH-10 audio level = 53   FX.25   75_______

+[0H] SP6PGH-10>APWW11,GM4SLV-10*:>100639zTest HF APRS station
+</code>
+  * a normal AX25 packet
+<code>

+  * both of these are also digipeated my me, shown on the last line is my outgoing digipeated packet:
