Radio Firmware Update

[Shawn Billings]

In Carlson for your rover, make sure that the message type (RTCM V3.0), frequency, Modulation (D8PSK), Channel Spacing (12.5 kHz), FEC and Scrambling all match.

I do not see the necessary settings options in the Carlson GPS Base settings to setup the base with the proper radio settings. I believe Carlson only sends new settings when a setting has been changed (although I could be wrong). If this is the case, you should be able to connect to the base Triumph-1M and make changes to position, and possibly even the frequency, without it affecting the SNRM and Base RtrNum setting from NetView and Modem.

Unfortunately, I cannot test all of this completely. I'm sadly either one receiver or one radio short of what I need. Give it a try if it doesn't cooperate, we'll see if others can comment Monday on what I may have overlooked.

Thanks for the weekend work there Shawn. Ended up with a Saturday project and wasn't able to work on this. Since we will be rained out... AGAIN tomorrow, I will be in the office and try to setup everything in the morning and report back.

I was going to, and probably should have setup this way in the beginning.
Documenting this procedure should be good though as I think this will be the ideal way to setup a system of my components.

I do not see the necessary settings options in the Carlson GPS Base settings to setup the base with the proper radio settings.

It is possible to send commands for any missing settings. The commands needed are:

%SNRM%set,/par/modem/b/uhf/link/protst/sim/snrm,on
%RtrNUM%set,/par/modem/b/uhf/link/protst/sim/mode/base/rtrnum,1
​

The easiest way to do this in Carlson is to place the commands into a text file like I have attached and then just use the "Send File" option in the Send Command screen.

WOrking it here.
I think I got the receivers updated. Working on the 35w. Having trouble connecting though. I can see which COM port it is on, but the darn thing will not connect. Net/Modem View will connect through. Trying a couple other tricks.

 

[Shawn Billings]

Run modemvu as administrator.

 

[toivo1037]

OK, got it. I redownloaded ModemVU just in case, and this time I ran as an administrator. That seemed to get me in.

I think I have everything configured. I will test it after dinner.

Edit: Shawn just posted. That was it.

 

[toivo1037]

May have broke it. Gotta go out and do some static work tomorrow, I will try to recheck my parameters and test it out in the field.

 

[toivo1037]

Just got back from the field. Looks like I have the T1 to T1 working OK on the 1 watt. Seems like my range may be reduced a little, but then again it was a crappy day, with sleet and lots of pine trees.

I also tried the 35w, and it did not seem to work. I set it up 1/4 mile from teh base, powered on, and the bluetooth light came on. DOn't think there should have been one, as there was nothing to connect to. I also noticed that there was no blinking on the RX or TX lights. The 35w didn't seem to be working as I had no radio at 2 miles, and would have expected to.

I am going to load it up after dinner here and double check the settings on the radio.

 

[Shawn Billings]

You should see tx and rx flash. If not then you don't have a repeater.

Blue light is on when the radio is on. It flashes when there is traffic between the radio and something else. Otherwise it's solid.

 

[toivo1037]

It looks like I have the correct settings.

 

[toivo1037]

Also, it has been along time since I bought and installed it, but I have Javad Mobile Tools on my phone. If there is something I can do with that.

 

[Shawn Billings]

I guess you are sure that the base was broadcasting on 464.75MHz?

 

[toivo1037]

I did not change any of those settings (on purpose). I will grab the base/rover and check.

 

[toivo1037]

Freq 440000000?
I saw that last night, and was a little confused by it, but did not change it. It is the same in the Base & Rover. Should that be the 464.75? FYI by antenna has 450-470 on it.

 

[Shawn Billings]

Yes. Set base and rover to 464750000. As I said, base tx and repeat rx must be the same. Repeat tx and rover rx must be the same. Otherwise the repeater will never hear the base and the rover will never hear the repeater.

440 is the default frequency after clearing nvram or installing new firmware.

 

[toivo1037]

440 is the default frequency after clearing nvram or installing new firmware.

That is where it got me then. Perfect, and thank you. I will change the Base/Rover and give it a shot tomorrow.

Freq 440000000?

The frequency is displayed in units of Hz, 440000000 Hz = 440.0000 MHz. Position the mouse cursor over any field in Netview for an explanation:

1 watt internal was successful.
35w was not. I set the 35w radio 3,000ft from the base and it was blinking receive & transmit, which it was not before, so I think that was working OK.
I then checked my rover at 1,700ft away from the 35w, and it was not working properly. The T1m light showed that I had antenna (or radio), but on the DC, it was showing that I had no radio connection. I double checked all of the radio settings again, and they are all correct, so maybe I missed something somewhere. OR, I was too close to the 35w. I seem to remember having to be like 2000ft out from that so the rover isn't overloaded. I have that problem where if the rover is too close to the base the radio is overloaded and I can't get the RTK connection. I have turned the 35w down to 15, and will give it another go. I keep trying to do this on a job with a deadline, so I don't have a tone of time to sit down and adjust and try different things. I will be able to do that later this month. IN the meantime I am able to fill in with the 1w, and network RTK, so I am not freaking out too bad.
