an opinion

Regarding the newest GEO. Once the GEO bird is in position and functioning, we just fix our antennas to one spot, no doppler, no hunting the satellite down, no planning for the next access time, or direction, no experimenting with hardware or various antenna systems, no ongoing challenge. I got into satellites many years ago because of the hunting, because of the difficulty and challenge. This is the ultimate “easy sat”. If one wants the easy sat this is your baby. Yes once established one can “work” lots of dx somewhat analogous to a phone call. A highly elliptical orbit (AO40 sob sob) makes one actually work, learn, experiment, and yes have fun. My opinion will no doubt be different from others. No flames please, just a discussion.

The new P4-A (Es’hail 2) satellite will be located a 26° East longitude (west of Istanbul, Turkey). You should “bookmark” the AMSAT-DL web page on P4-A. https://amsat-dl.org/eshail-2-amsat-phase-4-a This web page has the basic information on the P4-A / Es’hail 2 satellite. The satellite is NOT yet “in GEO position” for operation (typically several weeks) AMSAT-DL will announce, when open in 2019. https://amsat-dl.org/p4a-positionining-and-iot?utm_source=dlvr.it&utm_mediu… — The P4-A Satellite only has “S-band” UPLINK with RHCP and “Ku-band” DOWNLINK (Vertical for narrow; Horizontal for Wide) transponders. Their are Two (2) Linear Transponders : Narrow (250 kHz) and Wide Band (8 MHz) — I would suggest that you FIRST focus on your DOWNLINK (Receiver) setup. While Commercial solutions will require $$$, numerous Ku-band satellite TV components exist in the global market — as starting points for DIY builder. DIY solutions will require previous “Maker” / “Builder” fabrication skills & technical knowledge. IF you are an appliance radio operator, this is not a good “first DIY build”. — Roland, DF3LZ has been documenting his DIY Receiver Build (follow on Twitter @DF3LZ ) , using the Octagon Optima OTLSO LNB and the DF9NP PLL with 10 MHz GPS. http://lnbreviews.blogspot.com/2017/04/octagon-optima-otlso-pll-slim-twin.h… Dieter Leupold, DF9NP http://www.df9np.de/page2.html Price List http://www.df9np.de/Contents/Price%20List%20PLLs.pdf ==== From: "Gopal Madhavan" Subject: [amsat-bb] Up and down converters Any information available for up and down converters that use VHF and UHF radios to work the new Geo-Stationary satellite?

Dear All, I decoded CubeBel 1 TLM today for the first time and was happily surprised to read: "2:Fm EU10S To EU1XX <UI R Pid=F0 Len=256> [19:51:46R] [AA] [+++++++] ãÂ.@>þ+)Many thanks to DK3WN, UZ7HO and SatNOGS!i" I was really happy to see the callsigns of these 2 Guru’s which are doing such great job for the community coming down from the bird. My thoughts going also to many others doing/ enabling such great success for the community working long hours without even expecting any recognition or reward, it is so great that Mike and Andy are being recognized for their great work with messages coming from space. My personal congratulations to them and to all others doing tremendous work putting birds in space and the required tools required to enjoy the hobby. Please join me to say "Grand Bravo" to Andy and Mike, and to all others for their achievements which enable use to play with space technologies at home with relatively humble means. 73 Jean Marc (3B8DU)

Hi Gopal, For the downlink for es'hail 2 is on 10.5GHz for which DTH PLL STB + DTG dish can be used with an SDR. For the uplink on 2.4 Ghz we do not have the allocation in VU for satellite service. Hence I will be more on the listening mode using DTH STB + SDR. Commercial products are available https://shop.kuhne-electronic.de/kuhne/de/onlineshop/EsHail-2/ 73 Nitin [VU3TYG] On Saturday, 17 November, 2018, 6:14:50 PM IST, Gopal Madhavan <gopal(a)madhavans.org> wrote: Is any information available for up and down converters for using VHF and UHF radios to work the new Geo Stationary satellite?

Hi, My apologies but I need to capture some frames from FC1 so there is a redirect going on for about 30 minutes. Will switch it back later (scores will be amended appropriately) 73 - Dave, G4DPZ
