[Hamlib-developer] Understanding levels - Yaesu FT-991A

[Georgina J. <ge...@ge...>]

Hello All,

How do I interpret the levels  returned by my radio? For example:

l RFPOWER responds 1.0000.
l METER responds 32 and last night it responded 8 so I thought I had changed something. Not sure what METER is supposed to be.
l STRENGTH responds I assume  a DB level.
l NR responds 0.066667 What does this mean?? Is this the noise reduction option?
l PREAMP responds 10, is this off or is there 2 levels as the caps lists 10 and 20.

A lot of these levels have 0.0/0 listed in the caps and initially I thought that meant that that the radio didn't support that level adjustment. But now I am confused because it is not what it is telling me.

How do I adjust the frequency step? In Europe we use 12.5KHz for FM VHF? I am sure I saw some notation about narrow FM somewhere but can't find it now. I think my 818 accepts 9000 as the passband but the 991 does not.

Many thanks for any suggestions.

Georgina
