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

[Black M. <mdb...@ya...>]

Many of the levels need to "fixed" to show the range and step size.
I'll do that for the FT-991 this morning.  And I'll improve the rigctrl manual to show the units used by the levels.As for the levels you asked about.
Some levels are zero to unity (i.e one) where 0=0% and 1.0=100%RFPOWER NR
Some levels are dB PREAMP STRENGTH
Some values are Hamlib constants -- 32 would be the PO meter and 8 would be the drain currentMETER --      RIG_METER_NONE =    0,          /*< No display meter */    RIG_METER_SWR =     (1 << 0),   /*< Stationary Wave Ratio */    RIG_METER_COMP =    (1 << 1),   /*< Compression level */    RIG_METER_ALC =     (1 << 2),   /*< ALC */    RIG_METER_IC =      (1 << 3),   /*< IC */    RIG_METER_DB =      (1 << 4),   /*< DB */    RIG_METER_PO =      (1 << 5),   /*< Power Out */    RIG_METER_VDD =     (1 << 6),   /*< Final Amp Voltage */    RIG_METER_TEMP =    (1 << 7)    /*< Final Amp Temperature */

 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
