So far I have been 4.25 miles out with no glitches whatsoever when using this set.  It gives me the confidence to go higher and further than ever before.  If you’re in the market for a LRS, I suggest you check it out and compare the features of RangeLink vs. the other brands.

 

Firmware update release 3 included selectable RF RSSI or Link Quality RSSI.

To change between the two:

Make rangelink tx enter advanced binding mode, first beep end:
Set the two ways switch position
high power mode ==> link quality indicator
low power mode ==> rf rssi indicator

      What OS do you have on your computer? Have you tried running the program as administrator? I have problems with some of those programmers and windows 8.

    windows 7. and yea i’ve tried that and still nothing. it does the same with the RX and TX even though I have the correct driver and everything. and when i try to bind my RX and TX i cant get them to communicate, the LED on my RX stays solid and i get no response on any channels
