I can't get it to work after hours of trying. I must be doing something wrong but what?? I have a HPT404-BT external radio...if I go Setup button,edit,OperatingMode=RTK Rover (I'm guessing they mean select this to set up Rover and come back and do base separately???),position accuracy=float (because I get nothing at fixed and little at float, only get constant point with standalone, I'm guessing it is because my radio has never connected correctly, inspite of the fact that power on, bt=on, rec=solid and tx=blinking), start, stop, wgs84-itrf, THEN rtk corrections=???, if I put TR-2 Ext Radio then next=Ext radio is not connected to tr-2 receiver!, how do I connect it???, only"ok" which takes you back to rtk corrections??? so is it rtk correct=internal uhf?? if I do that then i can go on through the menu to record storage=??internal memory or sd card or dongle, i'm guessing sd card because one is installed but internal memory should work also,no?, then some more stuff that I leave at the default, then do I go back and setup the base, I guess yes or is that setting up the data collector/Victor to work with the base?...base=from list or I enter position or even auto positioning, ref base=wgs84itrf, rtk corrections=same as I put before which was internal uhf because tr-2 ext radio came to a dead end but maybe it wouldn't if I knew how to connect it?, a series of defaults, transmit=rtk-rtcm 3.0, period=1 (I heard it is better at .2 but I just want to get the thing working at any speed for now), sd card, more defaults and back, then with radio appearing to work, bluetooth connected, go to base rover setup, connect bluetooth device?? to rover, to base, to both, I do both, this time rover first, it says can't connect to ext radio, freezes a while, and eventually moves to the base-rover setup screen now showing the rover as victor ls pp281 receiver which is correct, but to the right of the bluetooth icon is "connect" and below incoming antenna is ok and outgoing = no and between the two it says no connection, so i hit connect again and it shows base as tr2 276 which is correct, and now as never before the word between the two antennas is "receiving", is that the radio???, i go to collect, hit start and ....nothing, antenna icon says ok100%, no data, no indication of fixed, float or standalone, nothing, but it shows satellite icon and 0+4 even though both base and rover have sat=green(8or more), both base and rover have blue light bluetooth, the radio has tx=blinking, rec=solid, bt=blue, power on, the circle/triangle icon is green on the base and red on the rover and I thought that referred to fixed, float or standalone so it seems they should be the same, no idea why they aren't, if I guess that I need to update one receiver with the config of the other, then my only option is from base because to base is greyed out, so I do and now the rover circle con triangle light is also green and I go back to collect, note "point description" has a red line through a icon upper left and the box says uhf, not the collect screen shows sat icon=0+13, seems odd, and start followed by no data points collected, sat icon changes from 0+13 to 0+0 and back again, all with both receivers showing green(8or more), and the circle w/triangle on rover turns red again, so i figure I will try again to go to tr2 ext radio, first base=tr2 ext radio and this time, unlike before, it doesn't tell it is not connected, no deadend, so.. defaults incl uhf protocol=javad, and no further changes, now to rover , tr2=ext radio yields ext radio not connected to tr2 receiver, perhaps that is correct because it is connect to the base but it is a deadend so I change to internal uhf, collect again=nothing, back to base/rover setup, all looks good including receiving and then it changes, loses the base, loses receiving, greys from and to base and start base, I can connect and I'm back to receiving and 2 oks, and it shows the base in right square, oddly in the left square it says bse id:0, from base is available and the circle with triangle light still red, so I update rover with base config again, no change...still can't collect, sat icon=0+14 or 1+14, how can that be if both receivers show green???, try the manual again I guess.....very frustrating
