[amsat-bb] Re: SSB Birds fm Hawaii
Hello Robert You would be in demand on AO-7. AO-7 is really not difficult though can be tricky. Keep in mind AO-7 switches between A B modes every 24 hours at around 2340Z, I think. Also our JA friends can not transmit on 432mhz. However they are on mode A. I have tried many times to work them from CN87 (Seattle) many times, no luck. Remember, if this were easy, everyone would be doing it. Schedual information can be found http://oscar.dcarr.org/index.php . Good luck with your efforts, I will keep an ear out for you. Don't forget VO-52. 73 Bob W7LRD Seattle - Original Message - From: Robert Smith duken...@pixi.com To: amsat-bb@amsat.org Sent: Sunday, February 5, 2012 10:09:32 PM Subject: [amsat-bb] SSB Birds fm Hawaii Aloha All de NH7WN I have been working the FM birds for years and now have the capability to QSO via AO7 and other SSB sats.

Robert, Remember also, we are looking for someone with AMSAT and AX.25 packet experience in Hawaii for out upcoming Arctic Buoy deployment next month. A Hawaii ground station is required to activate PCSAT-1 on an ascending pass to configure it so that it can hear the Buoy. We want someone fully conversant with AX.25 connections and remote-sysop experience with typical kantronics TNC's. Bob, Wb4APR ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Receive Pre-Amps for 70cm
I recently purchased an M2 Satellite Eggbeater antenna kit with the intention of working satellites from my shack. I think this antenna will work best with a pre-amp for the 70cm band that perhaps I can put in my attic close to the antennas. Who makes a good pre-amp for this situation to mate with my FT-8800 radio. Thanks, Peter KC2RBX ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: Receive Pre-Amps for 70cm
Peter, Assuming full duplex and no rf switching requirement (aka recieve only) my particular choice is DEMI's series of preamps. Cost $75 built and tested. If you're like me and don't mind a little solder smoke, and have access to test equipment for alignment, the kit is available for 45$. 73 es see you on the birds.

[amsat-bb] Re: Receive Pre-Amps for 70cm
Peter, A 70 cm preamp is always useful! There are a lot of them out there, but my experience is that ARR and SSB Electronics make the best. Definitely not the cheapest, though. http://advancedreceiver.com/page2.html http://www.ssbusa.com/gaasfet.html Be certain to get one which is RF switched, and which will handle your rig's power. No matter how careful you are, you WILL transmit into it someday. Been there, done that. You will need to split your single antenna jack on the rig to two lines. Almost any diplexer gives 50 db+ separation, but there are a few which are only 30 db or so. Worth checking. 73s, Alan WA4SCA -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of PETER SIMONSEN Sent: Monday, February 06, 2012 12:23 PM To: amsat-bb@amsat.org Subject: [amsat-bb] Receive Pre-Amps for 70cm I recently purchased an M2 Satellite Eggbeater antenna kit with the intention of working satellites from my shack.

[amsat-bb] Kenwood TM251 memory battery replacement
I have a Kenwood TM251A FM radio I use on the FM satellites, and the memory battery is going to need to be replaced. I figure sending it to Kenwood for replacement is going to cost more than the radio is worth. The only thing the manual says about it is to send it to Kenwood for replacement. Does anyone have more information on replacing it yourself? How hard of a job is it, and is the battery avaiable? 73s John AA5JG ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: Chibis-M?
Hi, I still receive Chibis-M (RS-39) on 435.315 in the late evenings. However, it isn't downlinking in morse code anymore. It sounds like it is downlinking data in a BPSK format, which I've not tried decoding. Another point to note is that it doesn't start downlinking until a long time into its pass. Presumably it is saving its battery power until its footprint is over Russia. Downlinking is also not continuous. One thing to be careful about is not to mistakenly receive Yubileiny (RS-30) which is also using the same morse code telemetry format on 435.315, and can sometimes be above the horizon at the same time as Chibis-M. 73's, Simon, G7WIQ - Original Message - From: normn3...@stny.rr.com To: Amsat amsat-bb@amsat.org; John Heath g7...@btinternet.com Sent: Sunday, February 05, 2012 3:17 PM Subject: [amsat-bb] Re: Chibis-M?
