[Dstar] ic2820h

[Richard Hoskin]

Hi Will,

Diversity works well when mobile on DV. It stops a lot of R2D2 and multi
path issues on RX. It does improve FM reception but is not as effective on
FM as it is on DV. It is most effective in marginal signal areas, hilly
areas or areas with a lot of buildings (with no nearby pager transmitters).

Nik's radio must have a louder relay than mine as I don't here the click
when it changes antennas.

Cheers
Richard
