Re: [amsat-bb] amsat-bb] dual dish feed for Oscar100?
by Edward R Cole 15 Feb '19

15 Feb '19

Gabriel, I do not know if available in EU, but I used an 86cm offset feed dish originally used for Ku-band satellite TV here in the US for receiving AO-40 2.4 GHz telemetry. It used a six turn helical feed and db6nt preamp to Drake downconverter to 123 MHz IF (FT-847). I use a 60cm offset feed dish, commonly used in the lower-48 states of the US for satellite TV for my 10-GHz station. Feed is W1GHZ linear pol feed with corrugated horn. Most likely you will need a CP feed for Oscar-100. http://www.kl7uw.com/Another_Dish_Tripod.pdf Many eme'rs are having success on 10-GHz with as small at 60cm though 1m is better (for eme). I suspect Oscar-100 signals are much stronger than eme. I am not QRV on satellite at present but have plans to restore my AO-40 antenna system this summer using a FT-736R on mode-UV or LU sats. photos of my old system: http://www.kl7uw.com/sat.htm 73, Ed - KL7UW ----------------------- Date: Fri, 15 Feb 2019 08:55:48 +010 From: "Gabriel - EA6VQ" <ea6vq(a)dxmaps.com> To: <AMSAT-BB(a)amsat.org> Subject: [amsat-bb] dual dish feed for Oscar100? I am looking for a dual band dish feed for 10GHz/2.4GHZ to use for the Oscar 100 downlink/uplink. What is your recommendation of either a commercial or a simple to build one? 73.

SatPC32

I purchased SatPC32 and received the registration code yesterday. Other than not having to enter my coordinates each time I start the program. I don't see any other features that were unlocked, or given access to, from the "demo" version. Am I missing something? Loon

Alan, Thanks for the heads up on the R&L Electronics price on the IC-9700. HRO matched the price $1799.95. So my $200 back will go for my 1.2 GHZ coax. 73 Mike K4MIA R&L Electronics has announced $1799.95 with free USA shipping. Looking better. No information on shipping date. 73, Alan WA4SCA

Doppler correction TM-V71A
by Ron VE8RT 14 Feb '19

14 Feb '19

Before commiting to a new TM-V71A, as it does not have CAT control is there a way to do Doppler correction other than manually selecting pre-programmed memory channels? In other words would it be possible to computer control the frequency from Gpredict or the Fox Telemetry software? Ron VE8RT -- Ron VE8RT <ve8rt(a)yknwt.ca>

Digi modes on Oscar100
by charlie＠sucklingfamily.free-online.co.uk 14 Feb '19

14 Feb '19

Hi All There has been some digital activity today on Oscar 100. I had to change uplink LO yesterday to a non-locked crystal controlled source, which has some small drift. This is making it impossible for me to use narrow tone spacing modes such as FT8 and JT65A. During a QSO with OZ1CTZ we were struggling with him decoding me on JT65A and he switched to JT65C after which the QSO proceeded perfectly. My drift problem on transmit is probably similar to that which would be experienced by unlocked Octagon users, so choosing a digi mode that is more immune to drift seems desirable. I did some testing here earlier using the Goonhilly SDR to feed audio to WSJT-X on a second PC and found also that JT9F (Fast) works extremely well with 100% reliable decoding. I've been testing with 10s periods mainly, but 5s also works. With these faster modes, drift will have less effect. JT9F is available in WSJT-X and needs to be run with VHF and up features enabled to access the 'Fast' checkbox. For JT65 users, I would recommend WSJT-X v2 over earlier releases, as the JT65 decoder was improved recently to cope with larger drift rates. If anyone is interested in trying this out, pse PM me and would be very happy to try it. 73 Charlie G3WDG

Re: [amsat-bb] Remove hard stop in G5400B?
