The problem with FM/AM modulation and Hermes-lite

Hello, there is a problem with FM/AM modulation and Hermes-lite hardware. As on screenshots see, there is a carrier appears at the monitoring frequency if FM or AM modulation is turned on. The bandwidth is not affected.

You are showing USB at 2.8 kHz on top and NFM at 12 kHz on the bottom. xSB and NFM have completely different bandwidth selections. USB has no carrier, as should be if TX is enabled. NFM has carrier, which should be if TX is enabled. Perhaps you could show your Transmit settings.

PS: Posting the same problem twice is counter productive.

I will check this soon but it does look like a bug.

Cannot reproduce that here with my Hermes Lite 2. May be totally irrelevant, but are you running the latest Gateware for your model of Hermes Lite?

SW used Hermes-Lite, not "2". It works without any gaskets.
