Hi Rob,

congratulations to Jay and you for the successful experiment!

I've started another SpecLab instance which is monitoring your frequency. Best chances to Eu are probably between 1 and 5 UT. Hope you'll be able to run max power soon - every little dB will be needed!

Good luck,
Markus (DF6NM)

Jay,

Thanks for confirming that my current setup is actually getting out with a message that can be decoded! I’ll continue transmitting this message over the weekend to test out everything in the tx chain. Have reduced output power by 3 dB while looking for any hot spots that may develop with the 100% duty cycle.
