Operating Manual Menu

Menu Entries Explained

Can't see the menu entry you are looking for? Document it for your fellow mcHF users! This page is filled in an opportunistic mode (i.e. entries are only documented as needed).

The menu entry is documented but now in a different menu? Move it around. You could describe it better? Do it!

In general the entries will cover the newest version of the software, comments will make sure if there are important differences to older version.

TX Initial Muting Time	0 - 250ms	10	When switching from RX to TX the audio and HF output will be muted for roughly VALUE ms. This does not apply in CW mode.	From 1.5.4 shown as milliseconds (before was 1 == 10ms). Default changed to 10ms, was 0. There are now several minimum times for muting defined in the firmware: Input from Mic: 100ms Input from Line In: 50ms Digital USB Audio (USB DIG): 20ms Digital Inputs (CW, USB IQ): about 1.33ms. If the user defined "TX Initial Muting Time" is set to more than zero, the maximum of both fixed input time and user defined time is used.
XVTR Offs/Mult	OFF, 1-10	OFF	When connecting to an transverter, set this to 1 and set the XVERTER Offset to the LO Frequency of it.	The mcHF frequency is multiplied by this factor before the offset is added, so anything but 1 will result in each Hz in the mcHF being displayed as 2 to 10 Hz change on display.
XVTR Offset	0 Hz - ~4GHz	0	When transverter mode is enabled this value is added to the mcHF frequency after being multiplied with the XVTR Offs/Mult.	Use Step+ to set a good step width, much less turns if it is set to 1Mhz

Hi,

this is the source code and shows what happens:

if(ts.xverter_mode)         // transverter mode active?
{
    dial_freq *= (ulong)ts.xverter_mode;    // yes - scale by LO multiplier
    dial_freq += ts.xverter_offset;    // add transverter frequency offset
    if(dial_freq > 1000000000)        // over 1000 MHz?
    {
        dial_freq -= 1000000000;        // yes, offset to prevent overflow of display
    }
 }

So in order to have everything working as expect, set "XVTR Offs/Mult" to 1 and set "XVTR Offset" to 116000000 (116 Mhz in Hertz).

Assuming you are on 28.000.000 Hz and "XVTR Offset" = 0, setting the Multiplicator will not change the display, but once you now start increasing "XVTR Offset" you will see the displayed frequency raising until you reach 116 Mhz Offset. In order to get quickly to 116 Mhz, just use the Step+ to set it to 1Mhz. Yes, this works if you are in this menu.

Thanks for asking since I didn't want to look into this before someone asked about it. Now you gave me a reason...
