Using a Balanced Line Tuner

Doug
 

Hi, I¡¯ve just set up a doublet with ladder line to a MFJ Versa III Tuner to my 857D. I¡¯ve adjusted the tuner to the ¡°loudest sound¡±, about S7 on 20M. Next step is to transmit on low power and fine tune. Problem, no matter what I set the RF gain to I¡¯m only seeing 5-10W out on the tuner meter and it¡¯s all reflected. On the radio when I transmit, the SWR looks to be around 2-3, power under 50% (with radio RFgain set to 100W).

I¡¯m receiving fine, I live in Ontario EN94np and picking up brothers in the US clearly. Do you think there¡¯s a setting on the radio that I¡¯ve missed to make it work with the external balanced line tuner (I¡®ve played with menu item 085). Thanks in advance.

Re: Zebra Stripes fixed in my 857D

 

Hello,
I got 5 zebra stripes too. Today I opened the radio and by the way of SMD technic, using a small soldering iron and flux liquid, I refreshed as in a picture above is indicated in a square red box telling to "reflow these". I think to have done a very good job as you can see in the pictures I made.?
Unfortunately after powering on again the radio now I got 8 zebra stripes instead of 5. No lucky. The core of the problem should be there around but not exactly there I guess...
I will try something different next time.
Thank you.

Whether to fuse the line when using a fused power supply it depends on where the power supply fuse is before or after the transformer.? Fuses are intended to prevent the wiring from becoming a fire starter.?? In any case, with mobile installations it is necessary to fuse both negative and positive leads as near as possible to the power source.? For fixed station a fuse is not needed on the negative (minus) lead, but certainly won¡¯t do harm if present as are most OEM power cords.? ??Regards, Phil / K4PO

My radios are normally used in the bush (forest) and have a 1M cable to a lead acid battery, a fuse is pointless in this situation.

However if you run your radio inside a house and especially if its wiring is concealed then one fuse is sensible.

Re: NO ft-8 TX with FT-857D - Signalink interface and wsjt-x ¨C Need guidance

 

There is a resistor in series with the line in that opens very often. I would check it, see the service manual
