Re: [amsat-bb] Obtaining G/T of the satellite Ground Station.
The Software Orbitron, allows Sun tracking as an option, assuming your rotator system is compatable with this software. Rather than tracking a satellite you can change it to track the sun/moon, in the settings page It connects via WiSPDDE software to the rotator system. You then need a way of measuring the noise when pointed at the sun and pointed away from the sun. Measure the noise between the preamplifier and the Kenwood radio, but be careful of any DC power on the cable to power the pre-amplifier. The spectrum analyser should be OK for this job. ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

I'd appreciate any info on who repairs Landwehr preamps (VHF and UHF). Resurrecting mine from 1990 and they are both dead. They have what I recall to be the classic symptom of a blown GasFET, when you apply power you get about 30dB of loss. Jim WD0E j...@coloradosatellite.com ___ Sent via AMSAT-BB@amsat.org.

Re: [amsat-bb] Best Preamp for ATV 439.25 MHz
Hi Farrell, The best solution is to get a good GaAsFET 432 MHz preamplifier and retune them for the lowest Noise Figure to 439 MHz using a PANFI ( Precision Automatic Noise Figure Indicator ) like a widely know AILTECH mod 75 73 de i8CVS Domenico - Original Message - From: Farrell Winder fwin...@fuse.net To: AMSAT AMSAT-BB@amsat.org Sent: Thursday, June 05, 2014 6:50 PM Subject: [amsat-bb] Best Preamp for ATV 439.25 MHz Has anyone done research and found the best in shack preamp for Amateur Television on 439.250 MHz?

[amsat-bb] LituanicaSAT-1 update
Dear amateur radio operators, Apparently the satellite had not reset as was scheduled on June 5, 0100z and the transponder remained on for the rest of today. After today's pass over Lithuania we left the transponder working again and put the satellite to safe mode (no telemetry) to save some power for transponder operations, so please enjoy and use it. Next update in 24 h. 73 de LY1LM ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member? Join now to support the amateur satellite program!

Re: [amsat-bb] satpc32 %$#$ again
Hi Bob, Maybe just go back to using your OSCAR Locator?

[amsat-bb] Interest FN55 or FN64?
I will be in Bangor, Maine on the morning of Sat., June 7th. I expect to be able to drive a half hour north to activate FN55, if there is interest in that grid. I would be on the SO-50 pass around 1610 UTC with a pair of HTs and my trusty Arrow antenna. I can also activate FN64 on SO-50 sometime during next week if it is needed. Let me know if you need either of these grids. 73, Nick, KB1RVT ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

Re: [amsat-bb] Repairs Landwehr preamps ( VHF and UHF )
Hi Alan, WA4SCA and Jim WD0E I have inspected the VHF and UHF schematic diagrams at http://www.radiodan.com/ted_stuff/landwehr.htm and found that for 435 MHz the input GaAsFET Q1 is a widely well know MGF-1402 For 2 meters VHF the input GaAsFET T5 is a N Channel GaAs-Shotky Gate Tetrode (for example TEXAS S 3030 ) wich is more difficult to find BTW the 2SK571 or the 2SK406 should work equally well see also: http://www.google.it/search?hl=itgbv=2q=landwehr+preamplifierrevid=851705843sa=Xei=leqQU8-7D6eG4gTD5IDQBwved=0CHIQ1QIoBA In any case the Manufacturer of Landwehr was in Sweeden starting about 30 years ago and the owner of the Company was a radio ham active on 432 MHz off the moon. I have contact him on EME several time but actually I don't remember if he was SM6AKW or SM3CKU and unfortunately both of them do not appears on QRZ.com It should be nice to investigate onto the american callbook and sent to both a letter.

Thanks to WD9EWK, KC9TTR, and WB3JVD for my first QSOs on this satellite! It was a max 9 degree pass, with decent signals. I will say, if you are going to try this one, use the Celestrak or Spacetrack keps, since they are updated more frequently. 73, Drew KO4MA Sent from my iPhone ___ Sent via AMSAT-BB@amsat.org.

Re: [amsat-bb] Lithuaniasat-1 0120Z
Hi Drew. Glad you had a chance to work the bird. Paul N8HM and I made a contact on the earlier 23:43z pass. I lucked out with Murphy, my transmit HT's battery crapped out just after our QSO. Did not hear any stations on the bird other than the two of us. I don't have narrow band FM on that Kenwood HT but find if I hold the HT 3 times father away from my mouth and speak soft the bird has excellent audio. It is very nice of the controllers to allow us to work the repeater. I always use the Celestrak keps. 73, Rick Sent from Rick's iPhone 5 Great spirits have always encountered violent opposition from mediocre minds - Albert Einstein On Jun 5, 2014, at 9:32 PM, Andrew Glasbrenner glasbren...@mindspring.com wrote: Thanks to WD9EWK, KC9TTR, and WB3JVD for my first QSOs on this satellite!

Re: [amsat-bb] Lithuaniasat-1 0120Z
Drew, Glad to work you on that pass. I heard nobody else. I almost didn't hear you come back, as the satellite was just over the mountains to my east at that point. On the next pass at 0247 UTC, I worked AA5PK in Texas for my only QSO. This is a fun satellite. I hope it is available for our use on more passes, before it reenters. 73!
