Unless you have any known noise issues with the PS, you should be fine! Dave WA4WX

Can I power my AT-600PROII via the supplied power cable to power pole adapters and a distribution block that connects to my switching power supply by Samlexpower (SEC-1235M) that also powers my

That is an interesting construction. Can’t answer your specific question though. I was using one until this past week when I found that SWR through that choke increased at 20m and above. Or that is

What is the swr with the unun unterminated? It should be high between resonances. The SWR of a 50 ohm resistor is 1:1. A better test is the S21 as measured with a NanoVNA. That will show you the loss

Tim, I use a 4:1 Unun at the RT-100. Essentially, this multiplies input impedance range of the input impedance range of the RT-100. I don't recall what impedance range the RT-100 accommodates, but, if

Hi Ryan, I wasn't getting good results with my RU-1:1, SWR through it was over 2:1 on ten meters into a dummy load. Even though it's an HF UNUN, I Re-wound it and the SWR through it is 1:1 all the way

Tim, There is some debate about the 4:1 balun with your setup. I have always used a 1:1 isolation or current balun with my flat top and inverted vee dipoles with success, easy to tune. Before you make

Hopefully this is in the right place. And there's not a sub section for UnUn's and stuff. I'm on my phone and I don't see any of that. Anyways, my question for the group is WHY.... Why did they choose

Looking for a recommendation: I have a wire dipole antenna that is about 70 ft on a side fed by about 35 feet of 450 ohm ladder line. At the feed point I have a 4:1 balun that converts it to coax

Interesting.? Thanks, Peter. Glad all is copacetic now. 73, Kent K9ZTV

Hi Kent, the wrong chip has a sticker with ZPROII13K . the working one is the same w/o "K". 73, Peter DF6QT

Peter ... What is the version number of the chip? LDG used to put a sticker on them. 73, Kent K9ZTV

Hi all, got a replacement chip from LDG for my z-11 pro II . Seems i had a faulty firmware. Now it fits 1:1 to the manual. Outstanding good?service from LDG !! 73, Peter

Have a look at: /g/TransworldDatronRadios/message/2321 This details how I eventually tied my Z100Plus to my TW-100 it would have been much easier if LDG had just given me the

Why not ask LDG, afterall, they designed it. John VE7KKQ [email protected]> wrote:

The YT-450 manual states it is made to work with the FT-450 and FT-950, it connects to the radio by the DB-9 CAT and 8 pin mini-DIN tuner ports, will it work with other Yaesu radios that have the

On my Z-100, it puts into bypass mode. Toggle Bypass Mode:To toggle between bypassed and active mode, press the front panel Tune button on the Z-100Plus momentarily. The SWR LED will flash three to

The 891 requires a double male jumper from the trans to the tuner. So cable is needed.

MIKE HAVE YOU TRIED TO JUST USE TUNER USING THE TUNE BUTTON – WITHOUT CABLE TO RADIO AND SEE IF THAT HELPS -- I HAVE A IT-100 USE WITH ICOM AND NO CABLE WORKS WELL WITHOUT W9BLI
