The Radio Information Board

IS, Thanks for your insight. In a few sentences you have cleared up volumes of conjecture and nonsense. Two more questions, will configure 2.10.2 work for all 6.xx or do I need another version? Also, (assuming that this is a proper question for this forum) do you know of any sources for 6.xx radios?

In looking around for more 5100 (vhf) units, I see that there is a confusing array of firmware versions and model types ("ES" "Ascend" etc.) If anyone can identify the differences between the model types and the differences between the firmware versions that would be very helpful...
