TX with a Lime has been broken for some time now. I was hoping that it may have been fixed in the latest release but this would appear not to be the case.
A work around was to increase the TXdelay in the transmit options
I changed my TX on to around 40ms and this did help and make it more reliable
I have not tried my Lime yet with the latest release as went over to a Pluto but I find the Lime RX better than a Pluto .
Hope this may be of some help.
