AO-73 Doppler tuning conventions
by Bryan Green 29 Jan '15

29 Jan '15

I know I asked this before, but I want to be sure: When tuning on AO-73 (or any satellite where the UPLINK is of a higher frequency than than the DOWNLINK), Leave the downlink fixed, and adjust the uplink to compensate? I am familiar with the One True Rule for Doppler Tuning. I am interested in what most people DO. Thanks! -- bag KL7CN/W6 CM98

MMSSTV Setup ?
by Ted 29 Jan '15

29 Jan '15

Hi, Is there a set-up guide somewhere for at least the setup with the radio? The instructions in the read me file don't seem to have any info on the initial setup. I assume it needs to see the sound card somewhere (I have a SignaLink USB) (I have noted the other setup notes on the UK Amsat page) Any help appreciated 73, Ted K7TRK

Hamsat uses for a 3d printer?
by andy thomas 29 Jan '15

29 Jan '15

Hi I am thinking of investing in a 3D printer or using one at our local makespace. Here in the UK a magazine is offering a weekly build-by-component series to make a 3d printer that will run on a pc or mac and uses DOT stl files for the design. A lsow build but an interesting idea nonetheless. I have seen at ESTEC 3d printed model plastic cubesats and am aware of the experiment on the ISS but do not know the software used or data file format. I was wondering if anyone on the -bb has experience of using a 3D printer for outreach or (like SATNOGS) for building rotator gears, and if so whether the file extension DOTstl is an industry standard for this work? I wonder if the estec and nasa files would be reachable by, say, the freedom of information legislation, or would be handed over. many thanks 73 de andy g0sfj

ISS contact protocol
by Ted 29 Jan '15

29 Jan '15

I guess I'm a little fuzzy about what constitutes a valid contact when using the packet route. I have UISS up and running properly and can get into the ISS repeater and back out ok. So, last night there was a good pass for me and I throw out my CQ. The repeater heard me and came back in red. Couple of tries later I see, in red "K7TRK N6YG, 599 in Carmichael". I try to respond several times with my return message but never see me come back in red. So, is this just a partial contact as I did not see a red message from me to N6YG ? (I suspect it is) Second question: Can ISS contacts via packet be logged in LOTW as SAT contacts? Thank you, Ted K7TRK VUCC Sat #226

VHF Items for Sale [ PRICES REDUCED ]

FOR SALE==================FOR SALE===============FOR SALE=================== DEMI 2370 PA 60 WATT OUTPUT Built by Merle Cox, W7YOZ in November of 2012. This 11 1/4" X 17 1/4" rack mount amplifier includes a DEMI 2370PA, 2 DOW-KEY 12VDC input and output coaxial relays, a NARDA microwave 20 db directional coupler and detector (this samples power to display on the output power meter, which is located on the front face of the rack mount). It also includes T/R time delay (which can be varied), and rear panel TR control. Hookup is nearly as simple as adding a "brick" amplifier on the lower bands. I ran a short piece of flex from my IC-910H into a Bird wattmeter to measure input power, connected the phono plug T/R to a short cable running to the DIN plug on the back of the Icom, and connected the antenna. Maximum power is achieved with about 6.5 watts on input power, with measured output power at 64 watts! That's a lot of power on 1296. Perfect for DXing, contests, or even EME. The build quality is very professional. Enamel gray, with toggle switches, super neat wiring, labeled connections, etc. 12 VDC is via PowerPole cables, rig input and antenna output connections are all Type N. It even includes an instruction sheet provided by Merle to make set-up easy for an "appliance operator" like myself. $650 ================= Kenwood TS-60S 6 Meter, All Mode Transceiver. Good condition. Includes microphone and mounting bracket. Legendary receiver make this a high performance rig for the Magic Band. $425 =================== Yaesu G-800DXA Rotor. New condition, unused in original packaging. Great medium duty, 450 degree rotor with preset. Very fast rotor. $300 ================= Mirage D3010N 430 Amplifier. 30 watts input with 100 watt output. All mode amp. Powerpole connector. Untested but working fine when I put it in storage. (replaced with larger TE amp) $125.00 =============== Mirage D-26 430 Amplifier. 4 watts input with 60 watt output. All mode amp. Powerpole connector. Untested but working fine when last used in rover operation. $100.00 ================== -- -- 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf 6M VUCC #1712 AMSAT #38965 Grid Bandits #222 Southeastern VHF Society Central States VHF Society Life Member Six Club #2484 Active on 6 Meters thru 1296, 10GHz & Light

Re: [amsat-bb] AMSAT membership

> Happy to hear you have joined…where about are you located? I’m about 40 miles west of Chicago, in EN52xb. To all who took the time to respond: It was precisely this community -- and responses from this list that I’ve received to past queries -- that prompted me to enlist. I’m not usually a “joiner” but for exceptional organizations I do make exceptions. AMSAT certainly qualifies. Thank you all for the welcome and encouragement, and I’ll definitely now have my eye out for the mail carrier! I am definitely looking forward to exploring new operating opportunities, and hope to work you all. vy 73 de Tom WZ9U

WD9EWK @ DM23vx/DM24va on Saturday (31 January)
by Patrick STODDARD (WD9EWK/VA7EWK) 28 Jan '15

28 Jan '15

Hi! I will make a day-trip out to the DM23vx/DM24va grid boundary in La Paz County, Arizona, on Saturday, 31 January 2014. The spot I will use is a place I have visited several times in the past few years, at 34.0 N 114.21533 W - along a road north of the AZ-72/AZ-95 junction southeast of Parker, and north of Quartzsite. The weather forecast appears to have the rain clearing out by Saturday morning, and I'm hoping to be out there starting with the SO-50 pass around 1545-1554 UTC. I plan on being out there until sunset, or possibly through the SO-50 pass around 0158-0212 UTC just after sunset. While I am out there, I will work whatever satellites are passing by, including the NO-44 passes Saturday afternoon. I may also work the ISS passes around 0252-0301 and 0428-0437 UTC from wherever I happen to be, on my drive home. I *might* try to linger out in that area long enough to work the 0252 UTC ISS pass, but won't guarantee that at this time. I will use my @WD9EWK Twitter feed to post updates while I am out there. Use http://twitter.com/WD9EWK if you want to see those updates, but don't use Twitter. APRS also covers well in that part of western Arizona, and I will use WD9EWK-9 as my APRS call sign. You should be able to see my location using a browser at http://aprs.fi/WD9EWK-9 during my drive to and from that grid boundary, and at times during the day out there (including the NO-44 passes, if my packets are retransmitted by the satellite). After the road trip, I will upload my log to Logbook of the World. If you would like a QSL card to confirm QSOs with WD9EWK, please e-mail me with the QSO details. If you are in my log, I will be happy to send QSL cards. No need to send me your QSL card or SASE first. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/
