Hi,
I'm not sure where I came into this email thread, but
I can vouch for the Almos All Digital Electronics
digital display.
I've had one on my FT-101E for 2 years now. I made the
kit and put it into my own box.
Here's the URL:

It is easy build, easy to calibrate and easy to use.
I tapped off the octal plug that's on the cable that
goes to my external VFO.
