I see this calculation in ts870s.c val->i = (val->i * 3.6) - 54; According to page 97 of this TS870S manual http://www.radiomanual.info/schemi/TS870S_serv.pdf The calibrated values are S1=-101dBm and S9=-77dBm so that's 3dB per increment....not 3.6...and the offset will be different too. Have you ever calibrated your S-meter?
So get get from the TS870 S-level to dB your 44 value with 3dB/unit you end up with this: val->i = (vali->i * 3) + 25; Or 44 * 3 - 31 = 157dB = 100W (note dB as used in hamlib is just dBm + 107 -- i.e. referenced to 1uV -- so 157dB=50dBm=100W=70.7V) Your s-meter reading may not be linear or calibrated correctly since putting S9 into that formula gives: 9 * 3 -31 = -4dB = -103dBm and it should be -73dBm so something is off. I wonder if your TS870 was recalibrated to 6dB per unit or such. Can you give me some values from STRENGTH for the all the s-levels and like 1,5,10,25,50,75,100W so we can see if you're at least linear and how accurate your calibration is? 73 Mike W9MDB On Wed, Aug 5, 2015 at 9:42 AM, John Nelson <j...@rmnjmn.demon.co.uk> wrote: > Mike, > > > What rig model are you running?
