Re: [amsat-bb] Working AO-85 With An FT-817
Just to echo Bill's advice and relate my own experience.
I don't have any experience with the 817 as I use a 5 watts Chinese HT.
I programmed 5 channels on my radio with 435.160 as AOS through 435.180 LOS and 435.170 for mid pass.
Since I operate half duplex (I don't encourage this due to all the obvious reasons), I divide the arc on my tracking app in 5 segments to find the correct uplink frequency.
The antenna I use is an Arrow II. You will tune for clear signal then twist 90° to transmit. Twist again to receive. I understand Elk users don't have a problem with this since both bands use the same polarity.
Following this pass pattern, I've gotten into the satellite down to 6 degrees elevations. Also, I am only able to work the satellite on ascending passes (south to north) after it crosses the satellite apex.
It's is hard but doable!

I've made several attempts to work this bird with my '817, since it's winter where I live and setting up my IC-910 on my balcony would be impractical.
I programmed my radio with the nominal uplink and downlink at 435.180 and 145.980, respectively. I haven't made any contacts so far, so I'm wondering if I should adjust the uplink closer to 435.172. (I'm assuming, of course, that I haven't been blacklisted or some such thing, hi.)
Please advise. Thank you.

That's how I set up my '817.

It would be fun unless there were challenges, hi.

That's what I did for other FM birds like AO-27 and AO-51.

That might explain a few things. I don't recall having to do that for the earlier FM satellites that I was on.
Following this pass pattern, I've gotten into the satellite down to 6 degrees elevations. Also, I am only able to work the satellite on ascending passes (south to north) after it crosses the satellite apex.
I'll keep that in mind, particularly since the quadrant to my NW is clear of obstructions.

Thanks for the tips.
