Re: WTB: 3B4 plug in for RTTY
That could be problematic; the hor input isn't cal'd and it probably won't match the vertical plugin's impedance or gain. For symmetrical x/y displays of equal bw you will likely need 2 identical vertical amps, cal'd to the input sensitivity of the mainframe.toggle quoted messageShow quoted text

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?
