Switch several of my older dongles to this one: https://www.amazon.com/dp/B01HA642SW/ref=sspa_dk_detail_2?psc=1&pd_rd_i=B01HA642SW&pd_rd_w=JtW8R&pf_rd_p=733540df-430d-45cd-9525-21bc15b0e6cc&pd_rd_wg=fH2H2&pf_rd_r=YKVSGSYAFB36QD0YPV4W&pd_rd_r=2faf93c1-3ed6-11e9-936e-01fa71378c68 . This dongle seems not to drift much at the higher frequencies.
