Non CAT controlled Auto tuner for FT857D


 

? Anyone using A non CAT controlled AUTO tuner for the 857D?? ?I currently have the CAT on the radio tied up with? DXLAB software for rig control.? I have an manual MFJ tuner that I have owned for more than 25 years.? The thing is bullet proof .? I would like to use a? MFJ model (what ever) Auto tuner without? using CAT control for it.? I have seen Youtube segments that show MFJ Auto tuners being used on older equipment but they were not clear as to exactly how they were being used.


? I am aware that? ?LDG makes several tuners that will interface the 857d without using a CAT Connection,

The? AT 200 PRO II? uses the ACCY connector and cable for connection... The reviews for the LDG tuners are mixed.? So are some of the MFJ's.? I have not owned any LDG products.? But I have owned several? MFJ products and almost all performed up to expectations.


? So. if you have experience? using a auto tuner as I have described? or if you know of a handy dandy? ?Super y cable for CAT connection,? I would like to hear from you......here or? ?mycall at yahoo.com

Larry,

?The LDG YT-100 uses the cat port but provides a cat port for your rig control. so you won't be loosing anything. Yes you can use an MFJ 993 B autotuner without using a cat port. it will auto tune the antenna as soon as you key they radio on the band using either FM or AM modes. Just run the 993B in AUTO mode. hope this helps you out.

Larry,

MFJ, LDG, Palstar and others have auto-tuners that sense the RF and tune accordingly.

The Cat interface is convenient in that it tells the tuner that the band/frequency has switched before RF is applied to use any memories already tuned and stored rather than sensing the RF and running a quick tune to find the memories. This may only save .5 second in the best case.

?I have used all three of the above without a CAT interface without problems other than having to wait .5 to 3 seconds and for a new frequency up to 10 seconds (which would happen anyways) for a tune.?

Various LDG models function differently hence may be an explanation for some of the different reviews you get.

?

I use my PROII without an interface cable. Put on AM to get carrier and it tunes on its own when it detects transmission. It also learns band settings for the antenna, eventually reducing tuning cycle.


While my 857 power setting is global across all modes, I understood from previous comments on this forum that on later models (apparently) the power setting is per mode. I.e. you can preset low power on AM for tuning purposes.

?

Alternatively with a cable you can press tune button on tuner, to cause the radio to transmit carrier as well as putting the radio in low power until tune cycle is complete.

?

You can make up your own switch and cable to achieve the same. It does not require any CAT commands to do this, just a pin on the CAT connector and a pin on power connector (to switch to low power during tuning). Just simple wiring, so there is no big deal about the CAT cable.

?

If you do use an interface cable, I lost my previous (not PROII model) when a fuse in radio power cable went and the radio sourced power through the LDG instead. The LDG did not like this too much. It is worthwhile to connect the tuner power at the radio side of inline fuses (and for proper noise / ground loop purposes, to have fuse(s) as close to power source as possible) and splitting shortly after the fuse. ?
I guess it applies to any ATU, not LDGs only.
