910 19200
by Jim White 09 Feb '18

09 Feb '18

Sorry, I was a bit unclear. I'm looking to run 19200 data on the RF side of the 910 - against a couple of sats to be launched later this year that will use that rate on UHF. I would guess it's going to be like we do for 9600 with older radios - put in cables to directly modulator the TX and to tape the discriminator before any filtering.

KPC TNC and wisp. Conflict, or I missed something.!!
by Nader Omer 09 Feb '18

09 Feb '18

Hi All I used the same setup I used before except I changed the tnc to KPC9612 +.. Everything was fine with this setup. I worked Echo 51 satellite, tnc was samik @ 9600 .bpsand Hope1 tnx was mfj1278b @ 1200 bps.-------------- Now my main problem is:............ KPC 9612 + refuse to key my radio (Icom 910) from MSPE. KPC-TNC works great with any terminal programs, and keying any radios at both port. also I setup wisp on my laptop – windows 10 following the same steps of my friend Mineo Wakita at his nice website. I tested the wisp with mfj tnc and it was ok with windows 10 setup @1200 bps and on my old desktop PC. Last night manually I put the KPC+ in KISS mode, its works ok and the MSPE keying the rig at 9600 bps. Today when i was tracking the falconsat-3 ,the KPC refuse to key the radio again and it was deadly silent.........., i try every thing i knew ( i tested two units of the kpc+) but I keep pulling my grey hair since the last all week.....:( Any help appreciated.73's Nader Omer- st2nh

Looking for a mod for the IC910 to do 19200. No luck Googling or looking in the usual list of mods.

SatPC32 adding new satellite
by radiomb 08 Feb '18

08 Feb '18

Setting up 1st bird in SatPC32. When downloaded SatPC32 it had AO85 in Doppler.SQFAO-85,145980,435180FM,FM,Nor,0,0,Voice U/V but it did not show up as a sat to pick. I looked in the AMSATNames.TXT it was incorrect. So changed to 40967 15058D AO-85 I think that is correct. It still did not show up. What am I doing wrong? Other question the Doppler.SQF has 435180. The "Getting started with amateur satellites" book shows transmit freqs from 435.160 to 435.170. What should the Doppler file have for freq? Again just starting with SatPC32 and trying to learn how to setup the tables. If someone could send the Doppler files for the FM birds until I learn this I would appreciate. My auto antenna tracking is working fine thanks to everyone.73 Mike K4MIA

W5PFG/p DM70, DM80, DL79, DL89 Feb 15-18
by Clayton Coleman W5PFG 08 Feb '18

I'll be operating satellites casually from the DM70 area of West Texas next week. Starting the evening of February 15 through the morning of February 18, I will operate from DM70xo and some of the neighboring grid squares. Because I visit and operate satellites from these grids at least 2x annually, I will not be posting any skeds or taking individual requests for this specific trip. -- 73, Clayton W5PFG

A dumb question...
by Pete Parisetti 08 Feb '18

08 Feb '18

...that many people might be asking now. Rather than taking ballast - for that, besides marketing, is basically what a car is - couldn't one one the next test flights carry the P3E satellite that AMSAT-DL has had on the shelf for quite some time now? 140 Kg wouldn't make a hair of a difference for a thing capable of lifting 60 tons. Is anybody talking to them? Always hopeful, even after so many years... Pete MM0TWX

PSAT2 preps for delivery (maybe June launch)
by David G0MRF 08 Feb '18

08 Feb '18

Hi Bob. That's a sad story. Sounds like some interesting payloads. 1) How about a DoD licence for comms ? 2) Sell it to someone South of the border for $1 and launch it as a foreign satellite.......(where did I get that idea?) 73 David G0MRF As of tonight, PSAT2 finally has some photos as it prepares for final testing in our long arduous 3 year campaign. http://aprs.org/psat2.html The Status is that the FCC still has not processed our 2 y ear pending API notice as an Amateur Satellite because they claim there is some Federal "mission". But they have not said what they perceive that Federal mission is? Maybe its because our undergraduate students are "DoD employees" even though the satellite is 100% Amateur Radio with four transponders including AX.25, DTMF, Voice Synthesizer, PSK31, SSTV and HF,VHF and UHF amateur bands built as an undergraduate senior engineering project purely for hands on education in the radio art. Even the construction used only surplus student senior project electronics from student bins and any purchases used non-DoD and no-federal GIFT funds. We have tried every argument in the book, but because the FCC is sensitized to some past abuses of some Federal Labs in crossing the line, we are being tossed into the same dirty bathwater. Oh well. We have 2 weeks to resolve this long going 2 year SNAFU with the FCC or lose this long awaited launch. Oh, and it is going up on the next SpaceX HEAVY launch.... Either to space or the ocean... or into the closet if the FCC does not act favorably Bob, WB4APR
