LA-1K Max feed-through power?


James Barber
 

Just bought a FTDX-5000MP, which I will not be using with the LA-1K. I do, however want to pass the 200 watts from the the Yaesu through the LA-1K on its way to the antennas. Any issues here?

Thanks,
Jim N7CXI

Jim,

?

There is no problem. With the amp off, it will use the Power of the FT5000.

?

With the Amp on, there is a bypass that you can turn off, but then if your doing that then just turn off the amp and your fine.

?

One note you may want to heed. In menu optioin 171 of the rig, set it to MAX Power 50w so you don’t damage the LA1K unknowingly. It does go into bypass if its over 55w but just to play it safe.

?

You can always manually adjust it up to 200w if you don’t want to use the amp.

?

This is how I use mine. Store it as 50W and If I want only 100 w out then I manually adjust the knobs on the rig.

?

73 and Enjoy the beautiful LA1K

Further to my last. With the amp off it automatically thru puts connector 1. That is where you should put the FT5000 into. Connector 2 the amp needs to be on and that Connector selected on the amp. EG: The radio you want to use with the amp.

Thanks, Barry.

I only use port 1 on the amp, so it’s easy.?
The amp is powered off when I use the Yaesu, and there’s no PTT connection between them.

The Yaesu and the other rigs all pass through an isolated multiport switch connected to the amp input. All the antenna switching is done out by the tower with a remote switch.

If the amp will pass through the 200W from the Yaesu, I should be ok.

No issues at all passing 200 watts through the amp while it's off or in Standby.? I've done it many times.

No problem. I run an FTDX101MP and I turn the LA-1K off when running the Yaesu at 200 watts.
