Started Transmitting Letters
I finished writing the microcontroller code to read the GPS time and only start transmissions when the minutes value ends with a zero. The signal now stacks nicely in 10-minute grabs. Now that GPS and the oven is working well I’ve started sending my call sign (AJ4VD).
AJ4VD spotted in Pensacola, FL (W4HBK)
First spot occurred while I was actively adjusting the transmission length
AJ4VD spotted in Greensboro, NC (WD4ELG)
5x frame stack (mean frame) from the WD4ELG grabber reveals the AJ4VD signal much better, and confirms the GPS timer is working well.
