how to stay on EVDO while tethering (prevent falling to 1X)
 

From times to times, my mogul falls to 1X while tethering without I am noticing it. Is there anyway on keep it stay on EVDO while tethering and not falling to 1X? I'm in metro NY with great EVDO coverage. I am running the stock 3.35 sprint ROM, and have try to play with the preferred operation mode, while I set it to HDR, my phone doesn't work at all, either Automatic or Digital will do the same thing which from times to times, it falls to 1X by itself. Any helps are greatly appreciated.

You could try putting you're phone into EVDO Only mode (Start--Settings--Phone--Services--Mode of Operation--Get Settings). I think that will force it to stay on EVDO, but on the downside you won't receive any voice calls while it is enabled (that's my understanding anyway, haven't played with it).

On my phone I had to change the following reg entry to get Mode of Operation to show up in my phone settings:

HKLM\Software\OEM\PhoneSetting\HiddenModeOperation Page

Change the value from "1" (hidden) to "0" (not hidden).

Edit: If anyone knows a way to get the phone to more actively try to reestablish an EVDO connection after dropping to 1X, I'd also like to hear about it.

that's what happen, if I put my phone to EVDO only, then it's data only, can't receive voice calls. Even though I am in Metro area with plenty of EVDO coverage, my tether sessions still fall to 1X from time to time and will not get back to EVDO by itself. I hope someone can come up with a solution to prevent it falling to 1X in the first place.

This was on the XDA site, and is not supposed to restrict incoming calls. Any thoughts from a Senior Member?

I dont have this problem. What is unique about your case?

setting it to EVDO mode only has nothing to do with phone calls. the thing that stops you is that the sprint network currently does not allow the phone to send and receive both voice and data at the same time, so while the data arrows are bright white (data moving on the network) you will not be able to receive calls. if the data is idle, calls will work.
