Does anyone have any success in mode A? If so what type of 10m antenna?
Kevin KF7MYK
I use a 4 element quad...HOWEVER.. it receives 29.45mhz better off the back as the reflector acts as a director at that frequency, it is cut for much lower in the band 73 Bob W7LRD ----- Original Message ----- From: "Kevin Deane" [email protected] To: [email protected] Sent: Tuesday, November 5, 2013 4:10:02 PM Subject: [amsat-bb] AO-7 Mode A

I've tried AO7-A a number of times, but there's never anyone there to work. Back in the glory days of the RS Birds, Mode A was very active. I sure do miss them. They worked very well! 73, Bob K8BL

I loved the RS satellites. They're what got me hooked. I wish the plan for the next LEO was a new linear mode Mode A bird for a starter satellite not another FM 'Grid-Lock' sat.

When I started, I had a hand me down beat up yaesu ft-221R 2m all mode with an old cb mic with a mag mount antenna and a realistic 10m all mode radio that didn’t transmit and a dipole but almost everyday I was either listening to or working someone on RS-10…. ahhhh the life…. it was so good with those russian leo sats, all you needed was a tickle of a signal to work some folks, now today with a TS-2000LE with 23cm, all I see is that fm sats are always clobbered by over-powered users and transponder HOGS, no room to even try to make a contact, what with everyone in my area trying to over-power each other to have control of what little transponder room there is. What a person wouldn’t give for an “A” mode bird or 2 again…. sure do miss those RS birds, they were so much fun…

my 2 cents...back in the day I had a one wavelength loop looking up, I later added a reflector below it, hence a two element round quad looking up, it was some wire inside some pvc pipe. I would start with a quad beam at low elevation then switch to the "vertical" round quad when the satellite was higher. This was super for RS-15. I wrote an article for the journal years ago about it. 73 Bob W7LRD

John VE7JZ, Oh yeah, those were fun times on those various Modes. It was funny sometimes on Mode K when a station on 15M would try responding directly on 15M instead of via the 10M Uplink! That was a strange Mode, but I worked several Countries that way that you cannot do with any Sat or Mode now. The Russians did a great job with those RS Birds. There were strong signals and fun Modes and simple radios and simple antennas. Not the case these days. I remember leaving my XCVR on the 10M Beacon Freq in the Shack and doing things in another part of the house. When I heard it come on, I'd go down to the radio and work a half dozen stations per pass. With simple vertical antennas on 2M & 10M there was no worry about aiming, tracking, etc. You just got on and worked what you heard. 73, Bob K8BL

Yep Mode A was fun .... that's where a lot of us got our start .... back then more folks had HF rigs and 2M SSB rigs were easier to come by (even for a poor college student like me) .... now I think the landscape has changed a bit .... VHF/UHF radios are in much shorter supply and I don't think HF rigs are as commonly owned either (my opinion I could be wrong)
I'm still in shock that SAREX 1 was 30 years ago .... DAM I don't feel THAT OLD.
I'm sooo looking forward to the new linear transponder birds .....

Whenever I've talked about Mode A at the AMSAT Booth at the Dayton Hamvention, all I've ever gotten was rolled eyes and/or total lack of interest. They seem to like orbiting FM Repeaters and modes/frequencies that few people are equipped for. With the old RS Mode A Birds, you could do pretty well with a 10M GP and a Ringo Ranger.

I haven't been on A07 for a while. But, back in the "goode olde dayes", I used a horizontal 2-element 10-meter yagi with a 7-element 2-meter beam fixed 30-degrees above the horizon. That worked VERY well! Glen, K9STH

My first mode A contacts were with a 10-meter wire dipole in my garage attic, and a homebrew 2-meter turnstile antenna on a tripod in my driveway. Rig was a set of Drake B-line twins with the TC-2 transmit converter... 100% hollow-state!

Use what you have to begin with!
I made one QSO via Mode A with AC0RA back in September using a just a one meter diameter AlexLoop Walkham Portable Magnetic Loop on the downlink. One thing to remember is that the receiver on Mode A is not as sensitive as Mode B, so you need higher EIRP than on Mode B, probably around 100 watts or so, for a decent downlink signal.
Audio of the middle of the pass is here: http://www.youtube.com/watch?v=OJwmIKr1BZI
Keep in mind that I'm a mile southwest of the Capitol in Washington, DC. There are lots of buildings and lots of noise sources nearby. In the middle of a lesser populated area, I bet I'd receive a pretty good signal with this antenna. The QSO occurs about the 4 minute mark of the video, with the satellite at about 60 degrees of elevation. I don't think I was pointing my Arrow high enough while fiddling with everything, but even then, with about 20-25 watts EIRP on 2 meters, the downlink signal is going to be a bit weak.
