Tom and Brenda,
Although your raspberries get morning sun, are they getting the required 6-8 hours for good fruit production to include flavor and sweetness? Also they should be planted in well draining soil. Receiving 1 to 11/2 inches of water a week is also important. Fruit quality is also influenced when fertilizer or compost is applied. It should be done when the blossoms first open giving energy to the plant as it produces fruit. This is an excellent web site with details on growing raspberries with specifics in each section on purple raspberries. https://extension.unh.edu/resources/files/Resource000010_Rep10.pdf
I hope this information is helpful for next season harvest!
