ao-51 radio programming
Thanks to all who responded so far. These are the frequencies as I understand them:
145.92 435.310 not needed for low passes 145.92 435.305 145.92 435.300 145.92 435.295 145.92 435.290 not needed for low passes
qrp repeater
145.88 435.160 145.88 435.155 145.88 435.150 145.88 435.145 145.88 435.140
Does ao-51 need a tone?
also qrp. is that on the satellite end or the ground station end? (to use the qrp mode do I need flea power and a wet string or an LNA cooled by liquid helium and a 305M dish? - ok I'm being facicous but you get the idea...)

You are likely to get some varying answers, but 145.92 paired with 435.310, .305, .300, .295, and .290 for the normal repeater, and 145.88 with 435.160, .155, .150, .145, .140 for the qrp repeater when active. Some folks like to put in the uplink +/- 5khz Doppler shift too, but it's really fine either way.

I have a vx-6 I'd like to set up to work ao-51. what frequency pairs
should go into the memories?

Not for the foreseeable future, but it wouldn't hurt to program a 67Hz tone in case we do go back to using it.
also qrp. is that on the satellite end or the ground station end? (to use the qrp mode do I need flea power and a wet string or an LNA cooled by liquid helium and a 305M dish? - ok I'm being facicous but you get the idea...)
In this case, QRP means we ask the users to restrict themselves to 10w and omni or handheld antennas. The satellite output is anywhere from 300 to 800 milliwatts, depending on the current eclipse season.

I just stick the up and down frequencies into a memory, and copy the downlink frequency to the VFO so I can tune in 5kHz steps.

I use a homebrew "Arrow"-type antenna with a 3-element 2m yagi and a 5-element 70cm yagi, HB9ABX diplexer and a Kenwood TH-F7E. It's light and portable enough to aim by hand.
You need a 67Hz subtone to activate the repeater.

Gordon,
They took the tone access off AO-51 almost 2 years ago. Unfortunately, it is still shown on at least one of the AMSAT-NA pages, but of course it does not hurt to have a tone on.
