The one's I've seen only have a single analog input, so modification could

b somewhat major. I'm looking for something to use as a tuning indicator

on my radioteletype station (https://w6iwi.org/rtty/ ).

Thanks!

That's pretty cute! Reviewing the manual, it IS dual trace, but not XY. I

might be able to use it anyway. I'll try my bench scope in dual trace mode

and see how easy that works as a tuning indicator for RTTY.

Again, Thanks!

Oh that ITTY looks very fun!

Well, definitely pricier, but there are a few options with more than

one channel:

https://www.amazon.com/SainSmart-Handheld-Pocket-Sized-Oscilloscope-Channels/dp/B07JQ3HRMX/

At this price point though I feel like it might just be easier to

start from scratch with a fast microcontroller and a display, no?
