I know the first/easiest path to sat communications is on the FM birds (which I agree with), but when someone is ready to "graduate" to the linear sats, which would be the best/easiest one to start with?
Philip N4HF
I should have stated which equipment I have - that would make answering my question easier. :-)
I have a Kenwood TS2000X (purchased new in 2007, llight usage, and the ceramic filters were replaced a few years ago). Yaesu G5500 az-el rotor, and LVB tracker. Also M^2 2M-440XP-SS (in storage. but would only take about 10 minutes to hook-up).
(I'm doing a separate post about another antenna system, since I have a separate question about that, so as not to cram too much info into one post).
Thanks for the replies so far

Hi Philip,
I would recommend FO29 since it has a wide passband, a good downlink signal, and is in mode J so the doppler shift is less on it. Very easy to use satellite. Call CQ near the center of the passband and I am sure you will make some QSOs. It is also a little higher up than some of the newer satellites so it has a larger footprint of stations to work.
AO73 and the Chinese satellites have great downlink signals, but being in Mode B, they doppler shift is much greater so you have to tune your uplink signal much more often.
Remember that all of these linear satellites are inverting, so you want to transmit on LSB so you can receive on USB.

Hi Philip,
Several of them are very rewarding and rather easy once you are accustomed to linear birds. FO-29 would be my recommendation for "easiest" in terms of consistent behavior and high likelihood of successful contacts. "Easy" includes finding several or more good operators on most passes.

I'm starting up again after many years. I worked through AO-6 and the RS birds when I was DA1BB. my understanding of postings is that once I select the 2-m and 70cm FM frequencies, and the bird begins AOS I key in a tone to open the link, then change the tone to use when transmitting. Am I understanding protocols OK? I can hears many passes using my Yaesu FT-8800, an automatic switching preamp for both bands, and a set of M2 helicals for each band. Any advice is appreciated.

Hi, Dave!
Welcome back.
You have it right. But. Most of the time the link is already active on SO-50. Usually you only need to send the 67 Hz PL tone when transmitting on SO-50.
The other 74.4 Hz PL tone activates a 10-minute timer. Usually, someone else has done that.

While most of the activity in North America is on FO-29, there are also people working the morning and evening XW-2's, and weekend AO-73's regularly. You might try listening to the evening XW-2A and XW-2C passes. Don't expect much late at night on AO-73. It's usually quiet on the weekdays.
I highly recommend listening for each satellite's beacon as you familiarize yourself with the linear birds. It will be a fair indicator of how strong the signals should be.
