Utility Monitoring at its Best
Data Reception on HF Radio
New Screenshots from Joerg Klingenfuss
To coincide with the recent publication of his 2022 batch of professional frequency guides and monitoring books, Jörg Klingenfuss has sent the editor three more high-resolution official screenshots of signals received within the last few days of 2021. They show: Shanghai Radio (CHN) on 12382kHz, featuring a brand-new infrared map never seen before; Nha Trang Radio (VTN) on 4209.5kHz, and Hat Yai Air THA on 21949kHz - received against the background of a high (NOAA) sunspot number of over 140.
Our full review of the Klingenfuss Shortwave Guide 2022 will appear in the February 2022 issue of RadioUser.
