[amsat-bb] XE2/WD9EWK videos from February 2009 trip
Hi! After my first attempt at uploading videos to YouTube last night, I found 3 video clips from my trip to Mexicali last year. One clip was from part of an SO-50 pass, and the other two were during a shallow AO-51 pass, all on 22 February 2009. These videos were made by David XE2DAK using his Sony digital (still-photo) camera, so the video quality is not the greatest. These clips were from passes I worked in the city of Mexicali - near the state university, and at Mexicali's Ciudad Deportiva (Sports City) athletic complex. The SO-50 pass video can be seen at: http://www.youtube.com/watch?v=qf_pJw9qthM The two clips from the AO-51 pass are at: http://www.youtube.com/watch?v=3WskH1spZIc and: http://www.youtube.com/watch?v=qseb6JVNgvo 73!

[amsat-bb] Yuri Gagarin birth anniversary 9 March
Tomorrow 9 March 2010 will be the 76th birth anniversary of First Cosmonaut Yuri Gagarin. Expect to hear some interesting recordings from Yubileiny RS-30 - worth having that digital recorder ready!! 73 de andy G0SFJ ___ Sent via amsat...@amsat.org.

[amsat-bb] K4T DXpedition to EL84 Dry Tortugas 11-15 March 2010
Hello All, There has been mention of this previously, but here's your last reminder from the group as we make final preparations for the K4T trip to EL84, Dry Tortugas. Details here: http://aroadventures.org/page6.html Thanks to great organizing by Mike AC2V, we will have 2 full satellite stations and one portable setup (should it be needed). We hope to work some CW on the linear birds, since some members of the team are CW aficionados and we'll have 2 stations. To help people find us, we'll probably work CW around the target frequencies listed, rather than at the bottom the transponder--but tune and listen. We will be active on the following satellites with target frequencies listed as below: Target Frequencies for K4T 11 March - 15 March 2010: Gridsquare EL84 SatelliteDownlink Uplink - -- - AO-7 145.960 USB432.136 LSB (and CW) AO-27436.795 FM 145.850 FM FO-29435.860 USB145.940 LSB (and CW) SO-50436.795 FM 145.850 FM AO-51435.150 FM 145.880 FM(primary) AO-51435.300 FM 145.920 FM(secondary if necessary) VO-52145.910 USB 435.240 LSB (and CW) HO-68435.760 USB145.930 LSB (and CW) Possible satellite passes (time in UTC) to work K4T are listed at this link; we'll try to work as many as possible, but we might not be able to realistically work EVERY pass on the list (we'll try ;) ) http://aroadventures.org/page24.html There are thunderstorms possible, so we may need to shutdown a bit. And don't forget the awesome HF/6M contacts you can make! Here is the HF bandplan: http://aroadventures.org/page22.html And, we are dreaming about some meteor-scatter (EME? heh) using WSJT between passes, simplex operations, and band openings; we'll see. Hope to work as many fellow AMSAT-BB folks as possible. 73! -- Mark L. Hammond [N8MH] ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Current Handheld-Which is best
Heres another vote for the Yaesu HT rigs; I use a Yaesu VX-7R and I appreciate being able to program a single odd band split, memory channel (that require no pl), then I use the memory tune (MT) function on the radio and turn one dial back and forth to adjust for Doppler and the 2 meter transmit is ready to go anytime I squeeze the PTT. This set up works much better for me then 5 separate memory channels for every bird. The Kenwood HT's wont let you program that odd band split into a single memory channel, (dont know about others) however sadly, Yaseu made it so you cannot pass pl tones in the odd band split memory channels but of course you can pass pl tones in the other memory or VFO modes. In my short experience, the better question I will be asking myself next time I purchase, is which HT has the most sensitive receiver and has enough other functions to still get the job done, although my VX-7R receives ok, some of the problems I had, with what seem like nulls, using the Arrow antenna and diplexer, went away when a friend gave me a pre-amp to put between the antenna and the HT. (the preamp is the size of a quarter and a 9 volt battery, so its still nice and portable, not commercially available, sorry) Sure wish we had a good full duplex, dual or tri-band, HT that had an excellent receiver, (worked USB on both TX and RX) and had the modest other functions we need to work the satellites but the compromised HT's are still a bunch of fun, with a portable Yagi in the trunk, a spare 19 minutes (including set up) and a pass prediction schedule, can bring a big smile to my face when I am out and about, in the car.

We do not have a currently-manufactured TRUE DUPLEX HT available. Alinco tried - but the sub-band receive performance on their DJ-G7T is gruesome. I use and like the Yaesu FT-60R - for MANY reasons ... -Receives 108 to a gig -bulletproof case -strongest belt clip of any amateur HT chassis on the market -easy to manually program -1,000+ memories -large, easy-to-read display -and a battery situation that is great. Load up the optional FBA-25 AA alkaline tray with alkalines or NiMH cells, and you have FULL TX POWER available, is needed. Do that on, say, a Kenwood TH-F6a, and you have ONE-HALF WATT TX power. Oh - and the Yaesu FT-60R can be programmed for split freq ops - where is receives on 440 and transmits on 2M. Overall, it is a tremendous value for your money. Under $200 at HRO and AES and other authorized Yaesu dealers. Clint Bradford, K6LCS 909-241-7666 ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

The Kenwood HT's wont let you program that odd band split into a single memory channel, (dont know about others) however sadly, Yaseu made it so you cannot pass pl tones in the odd band split memory channels but of course you can pass pl tones in the other memory or VFO modes. Actually, you can program PL tones in the odd-split memories on a Yaesu radio. You just have to program the tones with both of the frequencies - even if you only need a PL on the transmit frequency. Make sure the T is lit up for a transmitted PL when you are putting the first (receive) frequency into the odd-split memory. I have never tried the Memory Tune function on Yaesu HTs. I have a VX-8R at home, but previously had a VX-2R and VX-3R that worked OK for satellites. I may give that a try. Still not a full-duplex setup, but an interesting way to deal with tuning the receiver for the FM birds. Another item on the to-do list... snip Sure wish we had a good full duplex, dual or tri-band, HT that had an excellent receiver, (worked USB on both TX and RX) and had the modest other functions we need to work the satellites but the compromised HT's are still a bunch of fun, with a portable Yagi in the trunk, a spare 19 minutes (including set up) and a pass prediction schedule, can bring a big smile to my face when I am out and about, in the car. That would be nice. Until that ever materializes, I've settled on a pair of FT-817NDs for my all-mode full-duplex portable satellite setup. Not as small as an HT, but that pair of radios is certainly adequate for what I do. Having higher-capacity internal rechargeable packs lets me run 5W without worrying about an external power source, or I can plug either (or both) 817s into a 12V jumpstart battery for extended operating time. After setting up the 817s many times at hamfests or in the field, I don't need much more time with the two 817s compared to using an HT or a 2m/70cm FM mobile radio. Hamfest demos using the two 817s on VO-52 or AO-7 have drawn much more interest in recent times, and they will be with me at the next hamfest I attend on Saturday (13th). :-) 73!

These radios also do an excellent job digipeating over ISS (when the D'ptr is turned on), Not that it's likely any time soon. What's that, a month or so now since any real activity? It was on for an hour two weeks ago, but that's been about it. Gordon MM0YEQ ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?
