I believe this was proposed as a new subband for satellites 30 or more years ago, but it was never adopted by the IARU.

The amateur satellite service is legally authorized from 144 MHz - 146 MHz and there are a few below 145.8 MHz (XW-2A, 2B, 2C, and LilacSat-2), but 144.000 MHz - 144.025 MHz and 145.800 MHz - 146.000 MHz are the only portions of 2m that are allocated in the IARU bandplans to amateur satellites.

Hello from Don KA9QJG Ham for over 40 yrs. Hope Everyone is staying Safe and Healthy.. I hope its ok to change the ongoing thread.. I have heard some New Hams using the Oscar sub bands for FM Simplex. Below Is the ARRL Band Chart Now Reads New

144.30-144.50

New OSCAR subband

145.80-146.00

OSCAR subband

They are using Freq 144.315 FM Simplex. One was telling a story over 25 yrs ago they were using this Freq and a complaint was made to the FCC He got a Letter from the FCC . And He called respond the complaint and told the FCC that this was the Old Oscar Sub band that had not been used since the sixties Sats were Not up and working anymore. And the FCC Said do not worry about the complaint. So after listening to all this on 144.315 over a long time I thought the best place to get a real answer would be here.

Thanks everyone Please Stay Safe and Healthy
