I'm either doing something wrong or I have the deadest radio I have ever used. I can barely get my local noaa weather station, which is a constant feed. Any ideas?
If you're not already familiar with DMR radios, programming an 878 from scratch can be a bear. There are so many settings and it doesn't take much to render one useless.
Suggest that you study a known functional codeplug to learn the structure, then build a very basic one for your 878... maybe just one or two analog channels first, then add one or two DMR channels, until you get things working correctly. Once the light goes on over your head, then you can start over from scratch with your "dream" codeplug.
If you're not already aware, there are numerous DMR-related videos and tutorials that can be found online. Keep at it.
