Re: WTB: 3B4 plug in for RTTY


I want to be able to display other signals as well as the common RTTY X-Y tuning indication without needing to exchange the modules.

why not use another vertical plug-in for external hor input?

I am going to use the 561B rack mount scope I have restored in an RTTY
setup. The time base I have does not offer an external horizontal
input. A 3B4 or perhaps 3T4 does have it. Does anyone have one to spare?
