Clifton Labs used to make a similar board - the Z10000. I've used them in
several radios. If you can identify a good tap point, they work well.
A quick web search says Clifton Labs is no more - they have been "acquired"
by DX Engineering. We'll see whether the Z10000 will continue to be made
or whether it will be cast off as a unwanted niche product. (...those
troublesome weak-signal VHF guys and their low production, complicated
stuff)
