[SD-User] Rig control problems

I've just installed V12.05 as a completely fresh install, in an 
attempt to sort out the problems I've had with rig control. The 
problems are still there, but I now have a theory about what is wrong.

The main problem is that the frequency is displayed correctly, but the 
band does not change correctly. The only case in which there is a band 
change is that if I set a frequency in the 18MHz band, 160m is 
selected.

Now it surely cannot be a coincidence that 1.8MHz * 10 = 18MHz, and it 
so happens that my rig control file has the line

10             : Frequency: Factor to convert to Hertz.

I suspect what is happening is that band selection is being based on 
the frequency read from the radio BEFORE this scaling factor is 
applied.

Many rigs have a scaling factor of 1, and of course on these the 
problem won't show up. Could the problem be fixed please?

My other problem is that entering a frequency in the callsign field 
does not set the rig frequency as the documentation says it should. 
I'm really puzzled by this as the rig control files appear to contain 
no instructions that would tell the program how to set the frequency. 
I therefore don't see how it can possibly work. Could somebody explain 
this please?  Does it work for anybody?
