[amsat-bb] Amsat-BB Elliptical Orbit Satellites & the ISS

I'm a fairly new ham and been working AO-51 and the ISS, so far. Can anyone tell me which (if any) satellites, that we can work, have elliptical orbits that would give us prolonged passes for longer talk times?

Lastly, I can hear lots of traffic on the ISS cross band but my 5 watt HT cant seem to compete. I have not been able to get a QSO on the ISS, in a dozen attempts. (Arrow antenna, got a bunch of SSTV pics from Richard Garriott but no voice) So I hope someone can respond to my call on the pass that begins about 2:01 UTC over Southern California, father away the better. (DM-13) Thanks!
