Frequently Asked Questions

Tranceiver does not transmit

Likely there is no signal on the right output channel or the level is too low. Please consider that the left output channel is connected to your rig's input and the right channel is used by the VOX circuitry. VOX only triggers at around 30-40% of maximum volume, please make sure the output is set high enough.


Tranceiver does not transmit stable / intermittently

One reason could be that the output level in too low - please see above.

Another could be strong RF in the shack. This is usually not a problem as the integrated optocoupler provides a good signal, but I've experienced it in rare situations with the KX2 and KX3. Try to re-arrange things a bit, have more distance between the radio/coax and your computer and the interface and try to ground the radio and the coax shield as good as possible. Some ferrit cores around the radio coax and radio cable could help, too.


I'd rather use my rig's VOX control than the builtin-in VOX circuitry

Either channel the ouput signal to the left channel only (mute the right channel) or do not wire up the PTT signal with the open ended cable. Some tranceivers ignore the PTT line if VOX is activated (e.g. Elecraft KX2/KX3).


The output volume seems to be too low for my tranceiver

DigiLink Nano comes with levels suitable for most transceiver's microphone input. Make sure to adjust the volume control of your computer's sound setting and check your tranceiver's input settings. If this is still not sufficient please open the device by unscrewing the two Philips style screws in the bottom and lifting off the lower half of the enclosure. Close jumper JP2 with a tiny drop of solder to increase the output level to line voltage. Be careful to not touch any of the components with soldering iron.


The input sensitivity is not high enough for my tranceiver

DigiLink Nano comes with levels suitable for most transceiver's headphone output. Please make sure to check you computer's microphone input level and your tranceiver's volume settings. Should this not be enough, please open the device by unscrewing the two Philips style screws in the bottom and lifting off the lower half of the enclosure. Close jumper JP1 with a tiny drop of solder to increase the input sensitivity. Be careful to not touch any of the components with soldering iron.


Receiving works fine, but nobody hears me

Please first check your output levels and align them with the requirements of your digital mode software and your tranceiver. If everthing is set correctly but you are still not able to transmit successfully, please check your sound card settings to make sure that feedback is disabled (Windows only, please see Windows Setup guide).
