Did you read the email contents please as I found your response a bit unhelpful!
The operator states she is aware of propagation issues.
But asks will these effect ‘audio levels’ or is there something else going on?
As a ‘visually impaired’ operator this might not be easy to correct/

Study the effects of propagation and MUF. It changes from day to night.

Since 20m works well, but the lower bands do not, I would besuspicious of how your antenna is tuned to the lower bands. Check the SWR ofthe antenna at the lower bands. It could be something else, but kind of hardto tell without being there. Maybe you can find a local ham to help you.John, WØZI-----Original Message-----From: main@WSJTX.groups.io <main@WSJTX.groups.io> On Behalf Of GeorginaJoyceSent: Wednesday, December 30, 2020 2:34 PMTo: WSJTX@groups.ioSubject: [WSJTX] FT8 success after sunsetHello All,I have noticed I can get contacts quite easily during daylight time,typically 20m and on 40m. I have observed 20m goes flat slowly after sunset.On 40m and 80m where I can hear activity during darkness, I find it nearlyimpossible to get a contact. Being a blind ham I cannot observe what of theaudio levels are changed by the onset of darkness. While I understand thatchanges of the layers of the ionosphere affect propagation. I do not knowwhat effects this is having on my audio levels. Are they excited or subdued?If so, are both affected? Or is it nothing to do with audio levels? What canI do to improve my chances of successful contacts during darkness? Itcertainly sounds like there's a lot of activity at night. So I assume theyare usually successful but why aren't I?Many thanks,GeorginaCall: M0EBPDMR ID: 2346259Allstar: 52178Locater: IO83PS
