The datasheet says that the maximum for back-to-back data is 6.5MHz.

We built a custom TeleGPS load for radio sensitivity measurements with
the lowest documented power level setting (0x03), and measured the
power out at that value of -31.75dBm on the test board.

altos: Stop attempting to ramp power on CC115L2014-11-07T00:00:06+00:00Keith Packardkeithp@keithp.com2014-11-07T00:00:06+00:00urn:sha1:80a0397dde2f787fb20fd2520b274b826c68ed5a
The PA register on the 115L isn't in any way monotonic, making the old
code broken. Just rempve it instead of fixing it; we don't ramp
anywhere else...

altos: Reduce deviation at 2400/9600 baud2014-09-07T03:39:37+00:00Keith Packardkeithp@keithp.com2014-09-07T03:39:37+00:00urn:sha1:f395bcaa620490954d4a42de9b4870bc12bedc91
There's no reason to use 20.5kHz deviation at 2400 and 9600 baud, and
if we get a better receiver, we'll want to use narrower deviation to
have less bandwidth sucking noise into the radio. The new values are
(nominally) 5.125kHz deviation for 9600 baud and 1.5kHz deviation for
2400 baud.

New compiler warning flags and moving to the nxp require a few minor
changes in the code to make it work.

This would prevent the cc115l driver from ever sending tones.

Try to recover from TX_FIFO_UNDERFLOW by resetting the chip at idle
time.
Do a calibration phase during setup.
Program power to ramp up to limit key down noise.
