| Tak, o te liczne ograniczenia chodzi i o to co dalej z "guidance to administrations" wyniknie w SP https://forum.batc.org.uk/viewtopic.php?t=8684 W UK przewidują 'zmiany w licencjach' Z opracowania DARC: "• If the “measures” are reflected in national authorisations/licences: • Amateur activities would be confined to those identified parts of the band. • The remaining 53MHz (or 40MHz) of the band would be subject to such stringent conditions that no sensible operation would be possible. • Narrow band activities can continue in the top part of the band 1296 – 1300MHz with some constraints and power limitations (compared to where we are today). • For broadband applications (e.g. DATV) at least 3MHz may be available around 1257MHz also with power limitations. • Analogue TV may be not possible[b] (depending on the outcome). • Current voice repeater shifts [b]would be unusable (although wider split could be possible). • In band DATV repeater outputs may not be possible (except maybe in the UK with our extension to 1325 MHz). • Amateur satellite operation possible in 2MHz of the band with power limitations." materiały do zapoznania: https://www.darc.de/fileadmin/filemounts/gs/redaktion/DARC-Portal/2023/2311/23cm_RNSS_G4SJH.pdf https://www.iaru.org/iaru-simulations-confirm-the-low-probability-of-interference-into-rnss-receivers-in-the-23cm-band/ https://www.mdpi.com/1424-8220/23/4/1770 - ciekawy opis przypadków interferencji https://www.microwavers.org/papers/ral2005/G3LTF-Galileo.pdf - jedno z wczesnych opracowań odnośnie możliwych zakłóceń https://amsat-uk.org/2023/03/19/austria-restricts-23cm/ "OE białą plamą" na 23cm ? https://pk-ukf.pl/pasmo-23cm-po-wrc-23/ - skromny apel by być aktywnym na tym paśmie. |
