LS not receiving UHF Radio

[Ron Cloninger]

The last time I used the LS was for staking and near the end of the day when I pushed the start button to observe a staked point, the LS would start clicking fast and the epoch numbers would go up in intervals of 3 and 4 instead of 1. This happened after I had been working 6+ hours. I restarted the J field problem on the LS and things worked normal until I finished. I briefly tried to hook up to the T2 to stop the job and download the base, didn't work, so I turned LS off and pushed the record button on the T2 to stop recording so I could download to my phone. Couldn't see any files of the T2 using the phone app. Tried to restart the T2 base the next day and couldn't.I did upgrade the firmware/software on both the LS and the T2, still didn't work. I seen the recent thread about clearing the NVRAM. I cleared the NVRAM using Net View and now the LS and the T2 will sync as normal, the LS will not receive the HPT435BT radio. I did try the manual method of clearing the NVRAM by holding the record button in while turning on. The radio LED light (right light on left side group of three) never flashed yellow, it flashed green, so I don't know if that indicates a problem or not? The LS's current firmware is UHF 3.2.4.13, Power Board 0.1.9.4, WINCE 7.0.57.0, J-field 1.11.0.172, GNSS (updated today) 3.6.3150630. I turned the LS on and it sent a crash report in. The LS is 00199. The last time I tried the system, the LS found the T2 and everything went normal, the first radio link TX? went OK but the second radio link RX? never would go OK. Looking at the home screen on the LS there is a Yellow triangle with a ! by the radio icon. The HPT435BT shows a bluetooth link, (blue light, flickers sometimes) when the LS shows the first radio link OK, the TX light will flash green as normal.Looking at the T2 the right 3 LED's are green, the Blue tooth LED is Blue. The radio LED (Right LED on Left side show nothing. Another thing I noticed is on the LS setup screen for the Base/Rover Setup on the left side (Radio) the Frequency and the Bandwidth Items will be red, the others are yellow. Hope all this isn't to confusing, but wanted to try and give as much information as possible. I hope there is a quick and easy solution to my problem, as I don't want to be without my LS/T2 system. I have come to rely on it for much of my survey work. It has been a great improvement over my previous RTK equipment.

Thanks,
Ron

This seems like it the LS became slow to respond for some reason after being on for a while. Restarting the LS is correct procedure to fix an issue like this.

See if you can see the base file in Base/Rover Setup by clicking the Rec button then "Manage Base Files". If the file shows up there you have the option to download it:

Another thing I noticed is on the LS setup screen for the Base/Rover Setup on the left side (Radio) the Frequency and the Bandwidth Items will be red, the others are yellow.

This is because you have cleared the NVRAM in the T2. When a parameter is red, it indicates that the base and rover setup profile are different. To apply the values shown on the left side of the screen for the radio you need to press "To Base" before starting the base.

Thanks, Matt
Did as you suggested and it worked. Quess I should had reviewed the manual. Now I will remember what the red letters and numbers are indicating. The LS and T2 are great products and I am very glad that I signed up for the trial and purchased them. This is an excellent site and I am always visiting to see what I can learn.
