On the digital voice front, I maintain several YSF reflectors, as well as an XLX Multiprotocol gateway reflector.

Power and height are moderate, but digital voice modes don't require an S-5 signal to work well. Here is a projected range calculation to a similarly powered mobile with a 5/8l 70cm antenna:

I have run tests from such a setup, and I have found actual usable range to be better than shown in certain locations, and poorer than shown in others. These projections are also for a remote antenna which is 1.5m above terrain; so range is much further if you are using an elevated base antenna.
