AO-51 BBS Help
by Ron Miles 23 Jan '09

23 Jan '09

Assuming that I have my TNC, radio and uplink ready for the next AO-51 pass, what exactly do I need to keyboard into a packet message so that anyone watching the BBS downlink will know I'm there. I have yet to see anyone in QSO or an indication there are messages in que. Here's a small part of the 9k6 downlink data stream from the 0202UTC pass. 73, Ron n6paa AMSAT #23760 PACB-1*>TLMI-1: &yIpP' ZTW +/`XW !"#$%&'()*+,-./01 2s3o4567897:;:< J=I>fH?@AWBCDEFG7HIJKLM PACB-1*>TLMS-1: C0:0D C1:44 C2:F6 C3:2F C4:04 C5:01 PACB-1*>TLMD-1: WOD:2 ATP:0 BMW:1 BMS:0 CTS:1 CTN:168 CTL:166 CTE:Fri Jan 30 00:30:05 2009 PACB-1*>AMSATN-1: >5 January 2009 ...

Hello I am looking for a source for a few feet of UT-141 semi rigid coax. Most places have a minimum $. 73 Bob W7LRD -- "if this were easy, everyone would be doing it"

XE1AO from DK88 via AO-51, 0117 UTC Saturday (24 January)
by Patrick STODDARD (WD9EWK/VA7EWK) 22 Jan '09

22 Jan '09

Hi! Omar XE1AO will travel to the town of Tecomán, in the Mexican state of Colima (central Mexico) in grid DK88, for an AO-51 pass tomorrow night. On the UTC clock, it will be the 0117 UTC pass on Saturday (24 January). Omar will be on for that pass, looking to put DK88 in as many logs as possible. Good luck, and 73!

Digital Mode Equipment
by Allen Vinegar 22 Jan '09

22 Jan '09

Looking forward to getting my towers and antennas up and moving from handheld to base station operation I have the following question. Using an FT-736R, what TNC/Modem model(s) will get me operational at 1200, 9600, and 38,400 baud? I am interested in currently available and supported models. I know that seems contradictory with an FT-736R, but what the heck! Thanks, Al W8KHP

Re: re 2 metre de-sensing

Hi all thanks for all information. My antennas are very simple homemade indoor yagis (2 x 12 X on 70cms) and (1 x 6 X on 2mtrs) the coax is LDF4-50 from just behind the radios to the rotator in the loft. The radios are about 30cms apart (1ft) and I wonder if I was to join both the outers together of the coaxes (an electrical bond) would this make any difference or would this create any more problems? I am just wondering this as my array is slightly different to others having PVC pipe booms and being indoors with no connectivity between antennas and radios for different bands? regards Gus ----- Original Message ----- From: Floyd Rodgers To: Angus Sent: Thursday, January 22, 2009 5:14 PM Subject: Re: re 2 metre de-sensing When using some other rigs, like ft847, others have suggested using a 2m/440 duplexer, since the 847 has separate ports. Others using different radios also suggest using the duplexer as a notch filter. Simply terminate the unused output port 2m or 70cm with a 50 ohm restor and waether cap. Does this make sense? ------------------------------------------------------------------------------ From: Angus <angus(a)young5769.freeserve.co.uk> To: AMSAT-BB(a)amsat.org Sent: Thursday, January 22, 2009 5:51:36 AM Subject: [amsat-bb] re 2 metre de-sensing Hi, thanks for all helpful advice on antenna separation etc. but I have a problem with my FT817 on 70cms (5 watts) de-sensing my FT-480r on 2 meters. I have managed to stop the 2 meter transmission blocking the 70cms reception but I find that with even 5 watts on 70cms this is still de-sensing the 2-meter radio, any ideas, or links to some good band pass filters (low pass or high pass that you may think will work?) regards Gus M0IKB -- I am using the free version of SPAMfighter.

I'll have to dig out some of the pictures I took in the Microsat Lab in Boulder Colorado, as they were under construction . . . - some of the test images from WO-18 (hard to call those pictures now) - a flowchart I made for TLMDC ... Sounds like a new webpage.!. I'll let yall know when it's ready. I've been so proud of the ol' AO-16 bird, I made solder connections for batteries, solar panels & regulators (BCR) on all four spacecraft. Who'd have ever thought it would enjoy such a 2nd life as a voice repeater. Speakin of the Microsat launch of 1990 - does anyone know the whereabouts of Dave Cowdin - WD0HHU ? He was there in Kourou for the launch campaign, but I've not heard anything from/about him for years and years now... He used to conduct AMSAT HF nets, and our local nets in Denver. * Mark, of course didn't recognize your N8MH - but your name looked more and more familiar as I wrote this. I looked back in my log sheets for 1990, and found AO-16 contacts with KB5MU, WD0E, KC4EBR, KC4SA, WJ9F, WA4SXM ... all on the same page. It says you were in WhiteRock NM at the time. Just readin those callsigns now, I can hear that raspy PB on PSK downlink... and hear the FT-736 beepin crazy trying to keep up with the 437 doppler. Seems you and Gene were on there most every night. You were my 4th AO-16 contact logged at 1904 on 30 Sept 1990. I guess that was via the digi, as I didn't log messages sent via PB/PG. We must have spent months collecting telemetry with Jim - WD0E, before we indulged in QSOs. Then I took down my tower and moved. My goodness - how time flies, nearly 20 years since I left Colorado . . . and you're in NC now... and I'm in Huntsville. Who'da thunkit.
