Re: AT--1000ProII remote operation problem

 

Glad you got it going. I wish Yaesu would do it the same as Icom but Yaesu has always been fiercely independent on their firmware almost to a fault.?
Re: AT--1000ProII remote operation problem

 

n5kbp Marty, thanks so much! ?I just tried your instructions and it works fb.... ?I was trying to make it too complicated. ?My only experience was using remote on Icom equipment and that calls for initiating with the radio tune button instead of the tuner tune button. ?Thanks again.... 73

Sorry, I think your name is Marty!
Re: AT--1000ProII remote operation problem

 

John, Thanks. ?Just to be clear you first push the FT-710 tune button and then push the ProII button? ?I haven't tried that since my Icom rigs don't require the ProII button to be pushed.
Re: AT--1000ProII remote operation problem

 

I have exact same setup and it works great for me. Just a medium touch of the tune button on the tuner and it signals the radio to key a carrier until it's tuned.?

My FT-710 will not tune my AT-ProII when connected with the ldg-y-acc remote cable. ?The tuner works fine manually or with my Icom 7610 connected remotely. ? Any ideas? ?Stephen n0bf

Test the impedance with the test leads connected both ways.? An electrolytic capacitor or reverse polarity diode can look like a direct short.

Thanks everyone for the responses. I should have mentioned?that the RT-100 is tower-mounted, so checking it at the unit is problematic?for me.?

Mike Z.'s response is what I was expecting to?see toward the RT-100 from the radio end. It seems to me that if you're feeding DC voltage down a coax to supply power to a device that you wouldn't want to see a dead short. The time-constant variation makes sense, as the DC blocking / RF pass capacitor is being charged by the voltage?from the ohmmeter and the only other DC path would be the circuitry inside the RT-100 that might have an indication on the ohmmeter.

It sounds like my RT-100 has a problem. I'll have to arrange with my buddy to come climb my tower to get it resolved.

Thanks again for the responses everyone.

Re: RT-100 has a Dead Short

 

Actually, LDG is pretty good about service and removing the unit is the easiest task. If they have to fix or replace the cables or connecors on the tower, that will be a whole lot like real work.

So, *I* hope it is the tuner, as that will be the easiest to fix.

Good luck in any case.

Re: RT-100 has a Dead Short

 

also, if you have a dummy load, the rc-100 can be checked with that and the swr meter

RT-100 has a Dead Short

 

Hello All - I have an RT/RC-100 combo that has worked very well for about 3 months feeding it with an ICOM 7600 barefoot at 100 watts. Now the RC-100 status light blinks. In checking, I see a dead short on the coax going to the RC-100. There hasn't been any tower that might have damaged the coax, so I strongly suspect that the RT-100 has the short internally. Has anyone run across this before? Thanks.

Further to my previous email regarding my AT-1000 pro II, not only has the Antenna # 1 position failed but I had to pull it out of service and replace it with my Z-II Pro II as it was not functioning properly. The Z-II pro II is working better than the upgraded one.

Re: AT-1000 Antenna 1 Position

 

Had the same issue years ago with an old AT1000PRO. The contacts on the ant relay have failed. Contact Mark or Dwayne at support@... .? Not that hard to change out.

Mysteriously the Antenna 1 position has quit working. Position two is working.
