When I first log in I see the arenas I can choose from and just to the right of that is the ping. it used to say 46 and now it says 98. What ping is best and why has it changed?
Your routing has changed. Your packets now have a longer rout / need more time to get to the server. That's nothing you or HTC has a direct influence on. Actual routing is done by your provider.
A ping of 98 however, is nothing to really worry about, as long as your connection is a stable one.
When I go to the DA and type on 200 can people see my text if not tuned to 200 or do I need to be typing on the ALL channel?
Only who has tuned to 200 can read 200
If I type on ALL can 200 people see my text? Answer to this is Yes I think.
Yes. ALL, when enabled, will be read by everyone
Whats the dif between Ch 200 and typing on ALL?
A long time ago, ALL was enabled in all arenas. When it was disabled in the MA, CH200 was used as a replacement by the players still wanting to have a general cross-country channel.
