RadioMaster Tx12-Tx16 + R84 - R86 - R88: Rf Signal Low - Rf Signal Critical

[@raumlox]

H, of course, this does not solve the problem completely, but it does better. The receiver is simply very sensitive and overload is inevitable. This is from manual "D8 and D16 compatible receivers MUST be frequency fine tuned before flight.
Once the radio is bound to the receiver:
Return to the RF Freq. fine tune option
1. Lower the value until the radio loses the connection with the receiver. Record the value (TUNE_MIN).
2. Raise the value so that the connection is restored, then continue to raise it until the radio loses the
connection with the receiver again. Record the value (TUNE_MAX).
3. Calculate the median between the two values (TUNE_MIN + TUNE_MAX) / 2 = TUNE_MEDIAN
4. Set RF Freq. fine tune to the median value"
Example
Connection is lost at -73 and +35; the median is -19:
Once the Fine Tuning value is known, it can be used for all models which use the same protocol.

@@raumlox thank you for the détails.i agree I had fine tuned and found out just small offset of +2 with signal lost above 10 so centering signal is indeed mandatory but as you write is independent of problem of jamming because of proximity.

Hi bro, i have tthe same problem with my new r88 in close range in different protcols , but d8 d16 can be tuned, except futaba sfhss. idnwtd

@@raumlox great to hear this. What do you mean by 'tuning d8'? I have not found any way to solve this issue only moving 1m away even with 'low power' in model of transmitter it happens some times
