I have heard myself on FO-29 with 50 mW to an Arrow (at a high elevation)
and made one QSO using 250 mW.
I've used 500 mW quite frequently.

Ken,
I agree with Bryan, for 364 of the days of the year. 5 watts is usually
fine and sometimes too much for the linear satellites.
This is really a function of how busy the satellite is, and how much power
the other operators are using. On a quiet pass, some operators report
success with only 50 milliwatts.
The one day of the year that you may have trouble with is Field Day, with
lots of traffic, and a few QRO stations.
I'm not encouraging you to use more power, as that can cause real problems
on AO-7 (usually causing it to crash or reset to Mode A) or FO-29 (usually
causing severe FM'ing of the entire passband). But be aware that your
experience on Field Day may be different than the rest of the year.
I do encourage you to use a good antenna (e.g., Arrow or Elk), a relatively
short length of quality coax (6-10 feet of LMR-240 Ultraflex, not RG-8), and
no connector adapters.
73, Steve N9IP

Five watts is definitely sufficient for the common linear satellites.
There are circumstances when it is nice to have a little more -- maybe
10 watts -- such as on a very low pass from a high location.
But, there are so many who use the 5-watt FT-817ND that you will soon
hear a chorus. :)

<snip>
The lowest output power of my radio is 5 W and that's more than
adequate for working linear satellites.
For example, I've often been on south-north FO-29 passes to the west
of me. From my balcony, I've been able to hear my signal, however
faintly, all the way to LOS. According to my tracking software, the
grid square where that occurs is somewhere on the Arctic Ocean with
the distance to the satellite usually more than 3500 km from my QTH.

Look for ops AA8CH and WW8W to be active from EN84 on Monday June 25th.
Tentative plans include XWs in the 1300 hour, and the morning (our time)
AO92s and the CAS4 passes. We might try AO07 and FO29 as well.
Transmission on linears will be fixed frequency and tuning for callers.
Bring your SAT gear to work with you if you need this grid. Email to AA8CH
with any questions. QSOs uploaded to LOTW as always.
Good luck and hope to hear everyone!

Some fine print (enlarged for easier reading ;-):
Regarding amateur frequencies: Amateur ground stations use special credits
that are designated to only amateur frequencies. Credits that are earned by
sharing commercial ground stations cannot be spent for using amateur ground
stations. Additionally, credits earned through amateur ground stations
cannot be converted to cash.
The only way to access amateur ground stations in the StellarStation network
is to share your existing amateur ground station to earn special credits
designated for amateur frequencies.
How it works: When you share your unused antenna time and earn credit, you
can then spend your credit to access other antennas, dramatically expanding
your communication window without paying for additional passes.
Users without a ground station can simply sign up to use any compatible
ground station on our platform with pay-as-you-go billing and no upfront
costs.
Work in progress? Vaporware? Too good to be true? Anyone willing to give
it a try?
Yes, I have signed up with SatNOGS, but my ground station is not yet complete?

Mode change made at 0158Z, and orbit earlier than planned due to a few
different reasons. Should stay in L/v through 0158Z 24Jun for the first half
of field day. Good luck! I don't recall ever having so many satellites
available before. Have patience with the new guys.

All those with satellite stations for Field Day, remember to calculate and
submit your scores for AMSAT Field Day as well as ARRL Field Day. AMSAT
Field Day allows working stations on multiple satellites, whereas ARRL
rules count "satellite" as a single band (working a station on a second
satellite is a dupe under ARRL rules). AMSAT Field Day also awards points
for uploads and downloads of Field Day greetings from store-and-forward
packet satellites (FalconSAT-3).
See the AMSAT Field Day rules and submission requirements at
https://www.amsat.org/field-day/.
There are 4 FM satellites, 12 linear transponder satellites, and 3 digital
satellites that will be operational during Field Day this year. Anyone
looking for the 100 point ARRL Field Day bonus should be able to easily
pick it up.
