cec 0.3v uv段发射cw，sdr收到的频率偏移，144.095发射，144.0973才能清晰抄收。 uv段ssb发射，艾迪欧uv88、sdr也便宜2k左右。这点儿偏移对fm没啥影响，但窄带就影响大了。我刷机之后恢复了校准文件的。

2k的话确实有点多，解决方法就是刷点其他的固件试试碰运气能不能遇到一个频偏小的校准。省事的话，直接记住自己的频偏2k就好了，如果你要打线性卫星，就在计算器上多加（还是减？）2kHz，要直频就直接调整呗。 k6的核准上给的频率容限~~具体多少忘了但我查过~~，频偏个2k好像也还没超出他的限制

I've flashed UVK6 with CEC, and the CW frequency deviation is around 2.3 kHz. Will this resolve the encoding issue?

CEC 0.3V
UV band transmission, SDR receiving frequency offset, transmitting at 144.095 MHz, clear reception only possible at 144.0973 MHz.
UV band SSB transmission; iradio UV88 and SDR are also available for around $2,000.
This small amount of offset has little impact on FM, but it significantly affects narrow-band signals.
After flashing the firmware, I restored the calibration files.

Having 2K channels does indeed seem like a lot. The solution is to try flashing different firmware and hoping to find one with less frequency deviation during calibration.
For a simpler approach, just remember your center frequency (2 kHz) and adjust accordingly. If you're working with linear satellites, add (or subtract?) 2 kHz to your calculator's setting. For direct-to-satellite transmission, simply adjust the frequency directly.
The frequency tolerance specified in the k6 approval document.~~I don't remember the exact number, but I did look it up.~~The frequency deviation of 2 kHz doesn't seem to exceed his limits yet.
