Recommended Power for FO-29?
It has been a while since I have been on FO-29, and I was also limited with power. However, I now have my TS-2000X running, I am going to give the old bird a shot. I have at my disposal 100W of uplink with my arrow antenna, I am going to assume this is too much. Is 25W or 50W more appropriate? Opinions?
Thanks, Chris KQ6UP
This is an "it depends" question.
At higher elevations, 5 watts is likely all you need into an Arrow, maybe even less. I can work horizon to horizon with loud signals using less than 30 watts into an Arrow, and have made QSOs in the 6,500 km+ range with just 5 watts into an Arrow.
Feedline losses, obstructions on the horizon (like trees), and overall traffic on the satellite means your mileage may vary.

Start with 10 watts. 25 or 50 is waaaaaaay more than you'll need.

I set up my station outside and have to hold my Arrow. Because of that, I've restricted myself to 5 W and that's usually adequate.

I once was told that on linear birds one should not have a downlink signal that is stronger than the beacon of the bird. Beware I'm new to birds, only been listening so far to both fm and ssb birds.
I need to either invest in another ft-817 or drag my ft-857 out side to use with my elk antenna.
I'm currently waiting on a pair of heil pro7, after that I should not have to many excuses for not trying to tx (8
Hope to hear you catching some waves.

For me, there were 2 things to consider. One is that more than 5 W isn't recommended for safety reasons since I'm holding my antenna. The other one is that my IC-910 can't go lower than 5 W.
