Re: AT-600PRO Autotuner and Yaesu FT-847
Although it is good to have the LDG tuner work from a rig with a tune command, but the LDG tuners can operate in automatic where when they see RF and SWR above 1.5:1 they automatically tune.? So only the RF cables need to be connected for them to work.
I prefer the command cable be connected, but if that is not an option just letting the tuner tune on it's own will work.? Just put the rig in RTTY or other CW cont? xmt mode and let the tuner do it's thing.

Re: Problem with FT-897 & AT-897+
From the AT-897 Plus manual:
"The 8-pin CAT interface connector is Kycon Connector part number KMDAX-8P, available from http://www.mouser.com/ as Mouser part number 806-KMDAX-8P. ? Pinning for this cable is one-to-one, straight through; all 8 signals are used."
Page 16 shows the pin-out as described above, one-to-one, straight through.

Re: Problem with FT-897 & AT-897+
I used two different cables, and as I think I noted, the YT-100 works perfectly with the 897, and the AT-897 works perfectly with the FT-857. The AT-397 just will not work with the FT-897.
Cables are not an issue and all settings are? what the manual says they should be.

Yaesu FT-710 working with a LDG 200 ProII
Yaesu FT-710 working with a LDG 200 ProII
?
Do at your own risk, works with my setup. Not ideal, but its a work around until LDG release a interface cable.
?
LDG Y-ACC control cable.
The BLACK jack plug of the Y-ACC interface cable is for the? 1/8” jack marked "Radio" on the rear of the LDG200ProII.
The RED jack plug is for the REM/ALC socket on the on the rear Yaesu FT-710.
?
The LDG200ProII will need an external power source. DC power in (2.5 by 5.5 mm power jack marked "Power", center positive).?
Power requirements: 11 to 15 volts DC at 500mA (750 mA max during tuning)?
?
FT-710 menu setting
Press - FUNC - OPERATION SETTING - GENERAL
?
TUN/LIN PORT SELECT = LINEAR
TUNER TYPE SELECT = EXT
?
Please note, the FT-710 TUNE button will not initiate the tuning cycle.?
?
It is recommended you follow the below procedure every time a tune is required.
?
Reduce the power of the FT-710 to around 10 watts before you initiate the tuning cycle.
Tuning is initiated by pressing the TUNE button on the LDG200ProII.
If tuning is successful the TX power can now be increased.

Re: AT-600 Pro II Apparent Heating
Hi great news, Thanks for the update Thanks Dave?
I forgot some history that might be confusing readers.? I found a bend in the RG-8X that was heating on the lower bands, replaced the coax and improved the cable routing.? The problem no longer exists on any band other than 10 meters.

Re: AT-600 Pro II Apparent Heating
I have done some more investigating.? The problem only occurs on 10 meters,? The model I constructed for the antenna on Expert MININEC shows that the impedance presented to the tuner should be around 284-j24.? This impedance is predominantly resistive.? I intend to confirm (or deny) this with my NanoVNA.? Should the AT-600 ProII have difficulty feeding a high resistive impedance?

Re: RU-9:1 Unun Burnt up Replacement
I've been buying my "un" boxes at the hardware store.? 4"x4"x2" boxes, and you can fit a 240 size ferrite in them easily.? I also use one of those stepped drill bits?from harbor freight to drill the holes for the SO-239.
FT200-2 and Teflon coated 14 or 16 ga wire will solve his problem. Putting vent holes in the box will release the heat. They are easily found on EBay or Amazon.
Here is a reference page:?

I agree. I used aluminum boxes for my projects. At the 100 watt level I always made KW versions of the transformers.?
This discussion got me to dig out my old Jerry Sevick “Transmission Line Transformers” book.?

Re: RU-9:1 Unun Burnt up Replacement
Putting all of this in a hermetically sealed plastic box isn't helping either...? Try a metal one so it can get rid of the heat.? Glue some heatsinks to it or whatever it takes.? There are better boxes out there.? That plastic box is about the worst thing to use.

I think to damage the core you would have to run a lot more power

Re: RU-9:1 Unun Burnt up Replacement
The core ferrite material is useless – it has a temperature at which its magnetic permeability changes permanently.? You can read about this on the Fair Rite website in a core datasheet. Cheers Colin VE3MSC ?

Subject: Re: [ldgelectronics] RU-9:1 Unun Burnt up Replacement? Curious... Not too much experience with baluns... When they are like this is there a real necessity for replacement?
What is the failure mode?
windings burnt open or shorting?
Some kind of damage to the ferrite core?
Winding shorting to core?
Or it just looks bad?
I can understand if the burnt enamel coating allows the wire to short to the core which i think could have been eliminated if glass tape were used for insulation.

Re: RU-9:1 Unun Burnt up Replacement
The curie temp for type 43 ferrite material is 130 deg C. At this temperature the ferrite loses its magnetic properties. Judging from the appearance of that 9:1 it probably reached the curie temp and is toast now. If you have a nanovna and a 450 ohm resistor you could rewind it and check it with the resistive load to know if it was still working. With validation, I would worry the tuner was masking a bad UNUN.

Re: RU-9:1 Unun Burnt up Replacement
I always use Teflon sleeving on my window gs. I couldn't tell by looking at the picture if the core had cracked. I assumed that's why you wanted to "repair" it. if it was electrically ok and just looked bad..it probably still works as it's suppose to, unless there is arcing and if that's the case you need to fix the antenna that's causing the trouble and runn tbe power level for that balun. I also agree with the fellow that stacks two cores so it doesn't get as saturated. ...my 2 cents.?

Re: RU-9:1 Unun Burnt up Replacement
Thanks for input! They wanted to repair it possibly all the memories of QSO and the fun of the day as a trophy or learning to repair. I think another was purchased!
I also agree it would take more juice to cause issues with the mix composition effectiveness but, I was just assisting with confirming the ring mix value.?
yea there is other Baluns I hear ya! I collect them all! never be without a bag of antenna parts!?
