Please HELP, my T2 is receiving data on limited Sat bands

Jim reboot the LS. While the splash screen is displayed press the hardware Home button to access the boot menu. Then choose "Reset to Factory Image". This should not delete any of your files or settings.


The command changes the L1 center frequently. When I checked your T2 it was still set at the default value of 1575 so it never got changed.
That surprises me. I ran a print command and it reported 1575 (when changing parameters several weeks ago).

Gentlemen,

Thank you for the help! I am going to move any important files (just in case) and then reset the LS.

Matt, If I clear NVRAM on the T2 does it delete all recent changes such as modifying the L1 center?

May not be in all cases but when I had calls with similar issues it has been on the base end, usually radio. The Home screen LS will show all it is seeing, but the collect screen will only show what both base and rover are seeing (I think, at any rate shows much less than should). So something wrong with base or base radio not transmitting everything it should.

I reset to factory image and nothing changed.
The number of sattelites on the home screen does not match the sat info page, although it does match the sky plot.

The T2 has the same 4 frequencies as shown in my original post.

Any thoughts on how to proceed from here?

I am going to purchase the 3-NR, but not until Sept...I need the setup working until then.

Jim, it will need to go to the factory for an rma.. We have a rental program for customers with rma's. The rental fee is $500 for the Triumph 2. You keep it until you get your unit back with no additional charge. So, if it takes a month or more you will not be without.

If it's an issue with the board then it may be Beyond Economical Repair. There is a $250 RMA inspection/investigation fee. After inspection a quote will be sent to you for the repair cost. You can decide then if it's worth it to repair or just put that money towards your T3NR.

Let me know if you want to move forward with the rma/rental.

Hi Adam,

The bulk of the work I am doing is engineering. It could be a problem without it for a period of time. I may be able to get away with network surveying until then. As it is right now will the unit qualify for the 3NR? How about the 1M plus?

Is the 3NR available now? I planned to purchase in September but I may need to move it up to July.

With the new purchase this close I don't see how it makes sense to repair unless it doesn't qualify for the discount...even then it's a risk.

The T2 is the only receiver we are allowing to be traded for the T3NR. With trade it brings it to $5600. Without it's $6450. These are available now but it will be a week or so before they will work as a base with the LS. This is being worked on now.

Matt is right to question the disparity in the satellites shown on the home screen vs those shown on the status bar - satellites screen. This should not be affected by the Triumph 2. I can't think of a scenario where this should appear.

It is very strange and I’ve never seen that before. Yesterday there were times when it only displayed 2 satellites but the Home Screen indicated over 20 were being tracked.

Jim, can you set the T2 up tomorrow in the open with it connected to a laptop with TeamViewer? I would like to take a look on netview and record a raw file for investigation.

Hi Matt,

Thankfully we have been swamped. I am sorry I have not replied to you and Adam...

Now the the T2 is not working properly I survey using CA-CORS as the base.

When connected and showing 15ish satellites in view, when I check the satellites status page it shows zero listings. The LS seems to collect points properly. Also when I move to he skyplot, it shows the satellite locations.

Is there a way to determine what's going on with the LS?

Jim, I took a look, the radio frequency, channel bandwidth and broadcast period were wrong for your radio settings. You definitely don't want the radio broadcast period set to 0.2.

Also you had the external antenna selected on the LS. Is it actually connected because it was not working.

I think we need to see on Netview to understand why it isn't tracking all the signals.
The system will not maintain the correct UHF frequency. Perhaps I made the change incorrecty. I noticed recently that one of my antennas was designed for a frequency range. I had the system set for a frequency outside this range. I made a change about a month ago to 450 MHz. I changed the frequency in the profile and sent to the base. When I start a new project I must go through the process of changing frequencies.

External Antenna. I use an external antenna when more than about 5 ft from the unit or the signal will be too weak. Any idea what is causing this? Perhaps my external radio's antenna?

Check the warning screens to make sure there aren't any warnings.

Then you could try creating a Live SD and booting from it to see if the problem still persists. If so then I think it needs a RMA.

When you clear the NVRAM on the base all the radio setting will be reset.

You use an external antenna on the LS? If you are not using an external antenna you must make sure the LS is configure to use the internal antenna. The best way to check the radio is to check the RSSI when you are 100' from the base.

HI Matt, It would great if we can connect the T2 to netview. I was under the impression that it was determined that the unit required an RMA. Currently I am only network surveying. I don't use a laptop but have access to one. I suspect the unit must be setup with a clear view of the horizon? I will post here when I can get it set up.

I don't believe there are warnings but will check.

Yes I use the external antenna on the LS. I can't get far without it.

Thanks for the info on creating a live SD as well as the expected RSSI at 100 ft. That will be very helpful.

As a side note, I use the equipemnt anywhere from 0 - 3 times per week with a typical topo taking no more than 2 hours. I baby this equipment and no one else touches it. It seems improbable that both the T2 and LS both are dysfunctional at the same time.

Do you find that the equipment starts to have problems after a given number of years? I have been using the LS, T2 and radio for about 10 years. Time flies when you are having fun.

This is not neccessary, if setup in the top level of your home or office it will probably still track satellites as long as there isn't a metal roof or being near a window should allow it to track a few satellites.

No

One more question...is the table above for the flexible rubber antenna on the external radio?
Yes

No


Yes
Hi Matt, I can set up the system in my office, adjacent to a window and will have access to netview if you would like to take a look at the T2 or LS. I have not configured a connection between the LS and Netview. The T2 just requires a physical connection to my PC and a few mouse clicks and it's connected.

I would greatly appreciate it if you have a moment to determine if the LS and/or T2 require an RMA.

Please note I have been chatting with Adam about upgrading my T2 to a T3-NR or T3. I plan to do this in the next couple of weeks or so. At this moment I am trying to determine if the T2 is damaged. Many of the areas where I work have no cellular service. Somehow I managed to complete a very small topo by connecting the LS to my clients WIFI on Fri (and that was painful with the poor signal strength). The probability of a decent outdoor wifi network that happens to cover the area I need to survey is very low, meaning I am dead in the water on sites with no cellular service.

The help that all have provided is greatly appreciated.
