The ver 2 manual of the 390 shows a major change-up for the frequency bands of the Spectrum Analyzer. All the kHz bands have been dropped and the unit does not analyze anything under 50 MHz.

Ver 2: Frequency band 1: 50 MHz -65MHz (FM Radio)
Ver 1: Frequency band 1: 150KHz – 534KHz
Etc. also for other bands

Does this represent a hardware change in the 390?
Is it possible to upgrade the firmware without losing these lower bands?

The reason why is because of the older spectrum component is not available anymore.

This sounds counter intuitive to me (I'm new to this and curious), but i'm sure it involves a lot of technical considerations to come to this design update, can you simply explain the pros and cons of this design? Thank you.

In the spectrum yes, it covers less frequency.

That's interesting. So v2 is not using the full potential of the hardware in terms of frequency coverage.

Yes, the RF spectrum has changed from V1 to V2. They have different firmware versions but has the same features.
