|Target Version||Fixed in Version||188.8.131.52|
|Summary||0002698: IC-7300 Vd Inconsistency between radio and HRD Display|
|Description||The calibration of the Vd: indication|
The Icom bar graph on the radio has an indicated range of 10 to 16. The measured supply voltage into my radio is 13.80 but the Vd: indication on HRD is 16.1. The 2 indications are correct at 13.0.
These are the measurements I've taken:
Thank You for hopefully correcting this problem,

This is actually kind of hard to fix because Icom doesn't document the feature very well. The manual says that the response for the Vdd query has a range of 0 to 255. It says that 0 means 0 volts (uh ...), 13 means 10 volts, and 241 is 16 volts. This isn't linear, obviously; but there's no mention of a function which properly converts the range is given.
I think the best we can do is trying the assumption that there's two linear ranges; one from 0(0) thru 13(10), and the other from 13(10) thru 241(16).
Most Icom radios have parameters like this; those that do have several (power, Idd, Compression; maybe S-meter, ...)
Maybe we can conclude that the Icom values given aren't meant to imply some range between 0 and 10 volts exists; let's assume that under 10 volts, the radio won't even operate.
That leaves us to translate the range of responses from 151 (10 volts) to 211 (16 volts). We can do so with this function:
voltage = 10 + (radioValue - 13) / 38
where radioValue is the value reported from the radio by the 0x15-15 command, and the voltage is the operating Vd voltage of the radio.
The customer here gives an "HRD reports" value along with an actual, measured voltage.
Turns out HRD is getting the value from the radio and dividing it by 10 -- I guess at some point, someone assumed that was correct or close enough. Given that, though, we know that the value reported by the radio is 10 times the "HRD Reports" number.
If we translate the values accordingly and use the equation developed above, we end up with values that are right on -- within about 5-hundredths of a volt. These calculations are all in the attached spreadsheet.

The only adjustable power supply I have is an HP E3630A, which is only good for half an amp towards the 20-volt adjustable output. That's not enough to power on my IC-7610, so I can't test this change directly.
And it turns out the IC-7300, IC-7600, and IC-7610 have slightly different mappings for the value returned from the radio to the actual current read. Rig Control doesn't have very good support for per-radio, scalable parameters.
And so, I've added it! I've used the new code for the IC-7100, IC-7300, IC-7600, IC-7610, and IC-7700. The IC-7410, IC-9100, and IC-R9000 don't document the Vd and Id query commands, so I've left them as-is. Maybe they could be fixed with information from Icom, maybe they should be removed.
Resolved with this checkin:
note that this fix addresses issues with Vd and Id, and fixes several radios:
Could've done a better job with cleaning up the old implementation, so I've done this checkin to fix it:
