[R-390] 14 mhz xtl

[Barry]

A fellow on the Drake Radio list has designed a very simple crystal replacement for the R-4B (et., al.).  It's made with an Arduino, a breakout board (essentially a programmable clock), and some simple programming.  I'm pretty sure the output is programmable for any of the crystals in the R-390 and have been toying with a way to implement it in that radio.

Thanks,
