The RF Workbench / Re: 4096 beacon goes wild soon :)

Looks like previous beacon is dead. I never heard it at home, his antenna was badly tuned, and looks like his solar panel see sun only half a day. So i made a new one. With L-network for working with endfed wire. Software much smarter. Attiny85 control everything. Masure voltages, if accumulator voltage lower than critical he try charge battery with 8% PWM to prevent reset controller when solar battery shorted by deep discharged accumulator. Also with telemetry after main message he transmit not very important information about beacon, six phrases, for example tranmitter power with one message, accumulator type with next message, in cycle. Antenna - 0.5 mm stainless wire.
And most important... i can hear it at home, on my WEBSDЯ, very weak, but better than nothing.
His marker - three dits with different length. 0.075, 0.1 and 0.15 secondswith pauses between dits 0.05 sec, marker period 3 sec. Transmission every 6 min.

later i try to tweak antenna performance.
