I'm sure he meant 51.0. - Al

> Hey Dale.  At the bottom  you have "51.1 mHz FM will be the mobile and pedestrian liaison frequency." Did you mean 51.1 or 51.0?  I plan to bring my AS-2259/GR NVIS so we can use that to compare against homebrew/amateur-tuned antenna.

I wonder if we set up an HF freq at big pocano for the other sites to reach and then big pocano to HQ via VHF? I've never done that before but I wonder if its possible?

You may have all the gear necessary for an experiment.  If not, other interested comm team members may be able to bring an extra antenna, supports, coax, tuners and switches to assemble an experiment and configure it for rapid signal report comparisons.
