Another long term project of mine is this eddystone ec958.
It’s the one with the dot matrix l.e.d readout.
The problem is the incremental oscillator has no output.
So no drive to the readout, & not working on the higher bands.
I’ve simulated the output with a sig gen & it tunes over its band & the readout works. Dismantling the thing is a real pain because it’s soldered into a close fitting copper oven stuffed with glass wool.
I had downloaded the manual, & had a look at it, but no joy.
Any advice before I chuck it? It’s been on the list but it’s a bit beyond me this one.
