CAS 7A has (or will have) an FM transponder in addition to the 3 linears ( 15/10;15/70; 2/70)Launch show 15 sep 2020. Not sure how they plan to schedule that, but it sounds like it'll be a fun bird.73Rick Tejera (K7TEJ)Saguaro Astronomy ClubWww.saguaroastro.orgThunderbird Astronomy ClubWww.w7tbc.org -------- Original message --------From: "Peter Goodhall (2M0SQL) via AMSAT-BB" amsat-bb@amsat.org Date: 5/13/20 12:11 (GMT-07:00) To: Tim Crawford tcarchcape@yahoo.com Cc: Amsat amsat-bb@amsat.org Subject: Re: [amsat-bb] Uplink Doppler Changes For FM Satellites Confused why you think Huskysat-1, DOSAAF-85 (RS-44), CAS-7A are FMsats they are all linear so please don't be putting any FM throughthem.Current FM fleet is AO-91, AO-92, SO-50, Lilacsat-2 and PO-101 nothing else.You still need to put Doppler correction into the memories on AO-91and AO-92 not sure why you wouldn't be there are so many chartsavailable just to transpose into the memory software.Peter, 2M0SQLOn Wed, 13 May 2020 at 19:52, Tim Crawford via AMSAT-BBamsat-bb@amsat.org wrote:>> Uplink Doppler Changes For FM Satellites Question.
