60m band not always recognised

Post by g3ziy »

I find that the BAND box under callsign and Operator in the main window does not always pick up the band from the frequency. Between 5313-5320kHz it appears, but not outside these frequencies. Also 5362-5371.5 kHz. Probably other frequencies as well.
Is there a file I can edit to set the UK 60m allocations so that Log4OMv2 recognises all the 60m UK spectrum?

The 60m band for UK licensees is split into blocks of allocation and they should be working correctly, they do for me!

So either your using the wrong bandplan because something is set incorrectly in the Station info of your config or your trying to operate outside the allocated sections.

Dont forget you could be out of band if using USB on 5.371.501 due to the width of your sideband.

See UK allocations and highest permissible frequencies here https://rsgb.org/main/operating/band-plans/hf/5mhz/

Hi Terry, thanks for replying. I think I'm all set up correctly. A screenshot is attached.
I noticed this when operating FT8 on 5357 with an audio offset of 600Hz, which is a carrier of 5357.6 with something like 50Hz of sideband, well inside the 5354-5358 allocation.

Problem is that when on USB Log4OM does not realise that your only using 600hz audio offset it just receives the frequency from WSJT which as you say is 5357.6 which is above the "Highest USB frequency 5355" if you look at the RSGB bandplan.

You can modify the bandplan_DXCC223.xml and make it a user bandplan by changing the top frequency which at the moment is set to the RSGB parameters as below.

<BandPlanRange>
<Band>60m</Band>
<Start>5354</Start>
<End>5357.001</End>
<EmissionType>PHONE</EmissionType>
<ModulationType>USB</ModulationType>
</BandPlanRange>

Or operate 600hz lower and use the admiral WSJT split (Fake it) system to stay in band
