Frank 2 "2011 Edition" Hardware Modifications

[bnevets27]

Thanks to @BaltasarParreira who directed me here after finding his project #https://github.com/BaltasarParreira/Icetube_Clock_NTP

After a bit of info from Pete at PV Electronics I was able to get my Frank 2 "2011 Edition" clock working with this project.

The key was the removal of transistor Q18 (MPSA42) and resistor R12 (10K), then adding a jumper from R13 to where the collector of Q18 (5.2v) used to be.

As explained to me by Pete at PV Electronics. The Q18 transistor is for inverting the input logic to support the br335 GPS module at the time, which will cause the output of the ESP to be inverted and not work with the clock.

With the those modifications and the ESP's TX (GPIO2) wired to GPS IN (pin 5) the clock is now updating the time via NTP.'

Thank you so much from providing this project!
