 ==== HEARTBEAT (HB) ====
-Heartbeats are a "Networking" mode for JS8, a station sends a HB and any station configured to Autoreply with Heartbeats enabled will respond with a signal report. Heartbeats can be sent manually or automatically every N minutes. Heartbeats are opt-in so you may see that stations on PSKReporter (and similar) are reporting they can hear you, but they may not be setup to respond to a HB.

 Stations that respond to HB requests may be suitable for other Autoreply messages such as those listed above.

 Similar to the store and forward mailbox feature, stations can also act as relays, where a message is sent immediately to the destination as opposed to stored and sent on request. This would allow a QSO to take place using a middle man station, note that this method of communication would be very slow.
+A relay message will look like this
+  M7ABC: 2E0XYZ>M0XXX Hello M0XXX I am talking to you VIA 2E0XYZ

+===== Troubleshooting =====
+==== Empty spectrum ====
+If your spectrum is showing up completely black or with a constant stream of fixed vertical lines try the following:
+  - Ensure your sound card settings are correct in the **Settings > Audio** section
+  - Try restarting JS8, sometimes it glitches if something has gone wrong
+  - Check that you are in the correct Sideband, you should be using USB
+  - Ensure you're plugged into the radio and have the audio levels set appropriately
+==== I can see activity but it won't decode ====
+  - One common issue is accidentally moving to the wrong frequency, JS8 looks very similar to FT8 and FT4, check you're in a JS8 frequency band.
+  - If you're in band and the activity is above 2500Hz, it may be FT4 activity, there is some over lap with the common frequencies used.
+  - Check you're in USB mode
+  - Is the signal starting before/after the horizontal lines that get drawn every N seconds? If so your stations clock is out of alignment, JS8 is dependent on the system clock similar to FT8. Try fixing your system clock using NTP or using the offset control in the **View > Waterfall Time Drift controls** menu.
+==== I can't find my issue or none of the above have resolved my issue ====
+Hop into Discord, I'm sure someone can point you in the right direction.
