AO-73/FUNcube-1 Fitter Message for The Queen’s 70th Jubilee Celebration
AO-73/FUNcube-1 is transmitting the Jubilee Fitter message on the BPSK Telemetry beacon which has a nominal frequency of 145.935 MHz +/ Doppler.

AMSAT-UK has decided to send a special Platinum Jubilee greetings message via FUNcube-1 (AO-73). Anyone who receives this message and uploads it to the Data Warehouse using the Dashboard can generate a certificate to remember this historic event. 100vw, 300px»></a>The Chair of IARU Region 1 Spectrum Affairs, <strong>Barry Lewis G4SJH</strong>, reports on the work being done in defending the interests of the Amateur Services in the 1240-1300 MHz band.</p>
<p>On the IARU Region 1 site he writes:</p>
<p>During the period May 4-10, 2022, the IARU continued to engage in the preparatory work for WRC-23 agenda item 9.1b in ITU‑R Working Party 4C (WP4C).</p>
<p>Work continued to develop the coexistence studies between the amateur services in the 23cm band and the radio-navigation satellite services (RNSS) operating across the band. New studies were submitted by France, China and the Russian Federation.</p>
<p>The scale of the problem for the amateur services is becoming clear. For example, the studies predict that even a 10W 23cm band station could cause interference to RNSS receivers at up to 30km on the antenna main beam heading. Although the level of amateur activity and the density of users is quite low (compared to other more popular bands) the issue remains that from a regulatory perspective the amateur services are required to not cause harmful interference to RNSS services.</p>
<p>The figure shows a sample of one result from one study submitted into ITU‑R and further illustrates the scale of the problem. In this example a station using an 18dBi gain antenna is used for both narrow band and wideband (ATV) transmissions and a range of power levels. The protection criteria for the RNSS receivers differs for narrowband and wideband interfering signals. The figure shows the distances out from the amateur station where the RNSS protection criteria could be exceeded along the antenna main beam heading.</p>
