First let us start with what I used until now for any Winlink session that
I made (either at home or portable in the field/forest/mountain).

## The old setup (on a linux box)

I use a Lenovo X1 Carbon as my daily driver. It is quick enough and compact
and I used it for a while now for hamradio stuff too. I never did FT8 or
similar "messengers" on it though. In particular I did some winlink sessions
using [Pat] in combination with [rigctld], [direwolf], the [AX.25 tools],
[VARA] (HF and FM) and [ARDOPCF] (never got one connection from home).

[AX.25 tools]: https://packet-radio.net/ax-25/
[VARA]: https://rosmodem.wordpress.com/
[ARDOPCF]: https://github.com/Dinsmoor/ardopcf

A more precise note on how I established different connection types is
[already
written down in the article before]({{< ref "64-packet-radio-vara-mobilinkd-and-digirig-on-linux" >}}
"Packet radio, VARA (FM+HF), Mobilinkd, Digirig and the SignaLink USB on Linux").

## Using Winlink Express on a Windows computer

I planned to use the Surface 2 Go tablet for Winlink and related tasks -- but while I
wrote down my notes in this article I finally realized that I want to user a more
powerful device than the Surface 2 Go. I ordered a used HP Elitebook 830 for this
and I finished the main setup already.

Most screenshots are still from the Surface tablet.

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

## ARDOP setup

Following some screenshots showing my settings for ARDOP:

![screenshot of the ARDOP GUI](ardop.png "The classic Windows ARDOP program.")

![screenshot of the Winlink TNC settings](ardop-tnc-settings.png "Settings within a ARDOP Winlink session")

Set the desired drive level within these settings. I usually have to set it to <kbd>87</kbd>-<kbd>88</kbd>.

![screenshot of the Winlink Radio settings](ardop-winlink-settings.png "Radio settings within a ARDOP Winlink session")

I use a Lab599 Discovery TX-500 (with Lab599 as the CAT option).

I also use a Digirig and I can therefore use the COM port to trigger the PTT function.

## VARA FM setup

## Packet radio setup

## What you have to look for

There are probably more things to keep an eye on, but those are the few ones that
I usually take care of.

### Time synchronisation

Most digital modes rely on accurate time settings, so you may synchronise with a timeserver or use
the GPS mouse.

### RX signal

In ARDOP try to get your receiving signal withing the green bar. ![screenshot of ARDOP signal level meter](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. ![screenshot of VARA HF signal level meter](vara-signal.png)

You can achieve this with different methods.

- Change the microphone level within Windows.  
  I try to leave this setting to <kbd>80%</kbd> but I sometimes have to adjust it a bit.
  It is good at <kbd>80%</kbd> for VARA FM, but for ARDOP I often have to increase it to <kbd>100%</kbd>.
- 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)

## Some nice shortcut commands for the desktop

I catch myself often doing quick looks into the device manager to verify
the actual COM ports are still what they are used to be and I am also adjusting
sound volumes (USB speaker & mic) very often.

I created two links on my desktop that open the device manager and the
extended sound options just with a double-click for me.

Device Manager
: Right click on the desktop, select <kbd>New ›</kbd> → <kbd>Link</kbd>
and enter `devmgmt.msc`. Hit <kbd>Enter</kbd> or click <kbd>Next</kbd>,
name the new link appropriate and you're done with this one.

Sound control
: Right click on the desktop, select <kbd>New ›</kbd> → <kbd>Link</kbd>
and enter `mmsys.cpl sounds`. Hit <kbd>Enter</kbd> or click <kbd>Next</kbd>,
name the new link appropriate and you're also done with that one.

The sound control shortcut may have a non-ideal symbol, to change it right click
onto the new shortcut, select <kbd>Properties</kbd> and click on the button
<kbd>Other symbol...</kbd>. In the next dialog I choose another file
(click the button <kbd>Search...</kbd> next to the textfield). I use the
symbol from `C:\Windows\System32\SndVol.exe` -- open that file and you can
choose between three simple symbols for this new shortcut on your desktop.
Close all dialogs by clicking on <kbd>OK</kbd> and that's it!
