Description

According to https://discourse.myriadrf.org/t/limesdr-s-maximum-transmitting-power-at-different-frequencies/1649 I would expect something like 3-5dBm maximum output power at 1.8 GHz.

Hoewever, when running at ARFCN 871, and even when manually patching LMS_SetNormalizedGain(m_lms_dev, LMS_CH_TX, chan, 1.0); into the osmo-trx-lms source code, I'm not seeing more than -3.8 dB coming out of the TX1_1 port of the device. Where does that 6..8 dB difference come from?
