Operation

I have a tuner made for a specific brand of radio (Icom, Kenwood, etc). Can I make it work the same way with other radios?
No. Tuners made for specific radios can be used only with the radio it was made for.

The radio interface cable for my brand-specific tuner seems to fit into the jack on another brand of radio. Will it work with that radio?
No. At best the tuner simply won t function. At worst it could damage your radio or tuner.

My tuner doesn’t tune when I hold the microphone button down in SSB or if I’m in CW and press the PTT.
The tuner requires RF power to tune. A transmitter in USB or LSB outputs no power when there is no modulation. Some LDG tuners can tune while you re talking...

My tuner sounds like marbles in a blender when it tunes
Yes, it does! Those are the relays switching 30 times per second and do make a bit of noise. This is normal operation. If you hear any relays click during t...

Can I connect an SWR/Power meter between the tuner and the antenna?
No, that will not work. A meter on the antenna side of the tuner will produce bizarre answers. The meter must be on the radio side of the tuner.

How do you get the tuner out of bypass.
Bypass is just the L and C elements in the tuner set to zero. Simply begin a tuning cycle, either memory or full. If the tuner finds that bypass is the best...

My tuner can t match my antenna; it stops after about a minute showing infinite SWR.
First, some LDG tuners have two antenna ports; be sure you have selected the correct one. Second, LDG tuners can match up to an SWR of 10:1; your antenna ma...

I hear arcing in my tuner when I transmit on high power. Is that a problem?
Yes, that s a problem. Be sure to observe the specified power limit of your tuner. Also, RF may be getting into the DC power supply. Try adding RF chokes to...

My tuner seems to lose its tune when I transmit on high power. What can I do about it?
This sounds like RF interference getting in to the tuner. It could be coming in through the grounds, DC, or coax. Try the tuner with the amp off and see if ...

Why does the SWR meter in my radio show a higher SWR than the indicator on my LDG tuner?
That is normal. The SWR meter in most radios is not very accurate (+/-10%). If it’s more than that, the tuner or radio may have an issue.
