RT 100 schematic


 

Does anyone have a schematic for the LDG RT 100 remote tuner. I have an issue with mine and found a burned resistor on the board.? I can't determine the valve to replace it with..
Thanks in advance

I have the manual in .PDF, I*ll share if you need it.

I have no schematic.? If anyone does and will share#.. ?Please〞ME TOO!

Folks,
years ago, when I bought the RT100 I prepared a Bias-T as per the Rev.
C of the manual, where the power was applied continuously to the
tuner.
While reviewing the schematics (v 1.2) posted on the new Zip file on
the Files section, I see the power is applied only by request, using a
pushbutton.
Should I update my Bias-T box? Is there any negative impact on the tuner?
Inquiring minds wanna know.

Jon :?

The power push-button on RC-100 bias-the/control box is an on/off button.
?
As the RT-100 uses latching relays, the ability to turn off power to the tuner effectively provides a "lock" function for the tuning.?
Sometimes I find that the tuner wants to re-tune on me while transmitting, so being able to get a good tune on a band and lock it to prevent retuning by removing the power?
is a useful feature.

Cheers

Michael VE3WMB?

I agree.? I use wire antennas extensively when portable.? Some nights when it is windy, the tuner will want to re-match the wire as the wind blows it in and out of tree limbs etc.? The ability to ※Lock-In§ a good tune to keep the tuner from trying to make it better helps.? Invariably, when the tuner attempts a retune, it always gets worse before it gets better.

?

This photo was last week.? It was 110-ft of wire, 40-ft vertical and the rest sloping down to a fence-line off to the right.? Operated on every band except 160m.

Jon,
Power is disconnected when the tune button is pressed. When button is released, power is reapplied, tuner powers up, goes through initialization sequence and SWR and frequency measurements made. Tuner then sequences and SWR relay setting made.
Schematic is difficult to read.

Al,
Is the RT-600 one available?
It is currently not on file.

Under files, discontinued tuner zips.
