Thanks, all - sounds like either finding a cheap IRIG display or hacking up a pi/arduino/etc. version will be the path forward. The IRIG displays I can find quickly on ebay are still priced for people building music studios, so...
RPi 3 B+ supports PoE with an extra hat, and you can get pi-powered 3.5" TFTs cheaply. This may work best. A friend also pointed me to some networked dot-matrix displays that will do NTP from timemachinescorp, which might be a fun diversion. :); -Dave -Dave On Fri, Jun 15, 2018 at 12:52 PM Bob kb8tq <[email protected]> wrote: > Hi > > I suspect part of the answer is “they are cool looking stuff, grab it when > it’s swapped out” …. > They are out there, but not on the surplus market. > > Bob > > > On Jun 15, 2018, at 12:10 PM, Martin VE3OAT <[email protected]> wrote: > > > > What about the clock part of the old AN/GSQ-53A frequency/time rack? > > > > It wasn't NTP of course, but ran off of 1 MHz (as I recall) and > generated IRIG-B for remote displays.
