## What I actually want to do
## Using Winlink Express on a Windows computer
I plan to use the Surface 2 Go tablet for Winlink and related tasks.

I like to have the sound control open to adjust volume levels.")

### ARDOP setup
Following some screenshots showing my settings for ARDOP:

### What you have to look for
#### RX signal
In ARDOP try to get your receiving signal withing the green bar. ![](ardop-signal.png)
The top blue bar will then change to green aswell.
In VARA HF make sure the left indicator is near the needle as in this screenshot. ![](vara-signal.png)
You can achieve this with different methods.
- Change the microphone level within Windows.
I try to leave this setting to <kbd>100%</kbd> but I sometimes have to adjust it a bit.
- Change the REF level on your radio.
On the TX-500 I usually maintain a REF level of <kbd>-19</kbd>.
#### TX signal
You may need to look into your radios manual to get the optimum value of the signal.
On the TX-500 I look at the DIG meter. Get the bar nearly full and you are good to go.

(The ALC meter on the TX-500 does not move a bit on my setup)
