=== Connecting to a server ===

== Tuning the radio ==
=== Fixed frequency radio ===
For crystal locked radios such as the softrock lite II or YU1LM sdr's It is necessary to use [[#Using subRx | subRx]]. The procedure is to set vfoA to your centre frequency, usually the crystal frequency / 4 and leave it alone as changing it will affect your centre frequency. Using the button on the vfo panel or the 'Receiver' Menu / subRx choice switch on the subRx. You can now tune within the limits of the sample rate of your sound card (48, 96 or 192 KHz) with your centre frequency offset from centre by 9 KHz.

Note there is still a bug in the display where the lower 9 KHz wraps to the upper 9 KHz but the audio doesn't track the spectrum so you lose 9 KHz of possible bandwidth.

=== si570 tunable radio ===

== Setting the noise floor ==
The height of the spectrum from the baseline is adjusted by rolling the mouse wheel with the pointer over the level calibration markings on the extreme left hand side of the spectrum window. This will at the same time change the base colour of the waterfall.

The procedure is: After setting the [[#Calibrating the S meter | sound-card gain]] you should remove the antenna and roll the mouse-wheel to give a spectrum display line just above the bottom of the window. When you apply the antenna the spectrum will rise in the window and the waterfall base colour should be dark blue unless the band is particularly noisy.

== Calibrating the S meter ==
To calibrate the S Meter, a signal equal to S9 (-73 dBm) is injected into the sdr and the soundcard gain is adjusted until the S meter reads S9. It will then probably be necessary to adjust the spectrum [[#Setting the noise floor | noise floor]] level.

A subjective calibration may be performed by tuning into a signal considered S9 and performing the above procedure.

''Quick Server List''

If you see that a public server's status is "Busy", please '''do not''' connect to it. Doing so will disrupt the user already connected. If you see a server's status is "Idle" or "0 client(s)", you can connect to it. If you see "1 client(s)" or "2 client(s)" etc., you are sharing a connection to the same server. The first client is the master who has control over the vfo and Tx etc., and you will be connecting as a slave. You will only be able to listen to the audio and see the spectrum passively as an observer. When the clients before you disconnect, you will automatically become the master. This is a queuing mechanism.

''Config > Audio''

If you are connecting to a public server on the Internet (ie not your own server on your LAN), '''please''' set Audio to 8000, aLaw, and 1 channel. If you use other settings, your QtRadio and/or the dspserver/server will hang.

=== '''The ghpsdr3-alex Project''' ===

This is a modification of the excellent Software Defined Radio (SDR) software by John Melton ([G0ORX/N6LYT][http://g0orx.blogspot.com]

The original software by John is called ghpsdr3. We are working towards merging the two projects (ghpsdr3 and ghpsdr3-alex) source trees to a single source. However BEFORE that happens, you CANNOT mix and match programs from the two projects. See note for HPSDR hardware users below.

Project README https://github.com/alexlee188/ghpsdr3-alex/blob/master/README [https://github.com/alexlee188/ghpsdr3-alex/blob/master/README]

Source Code is via git at https://github.com/alexlee188/ghpsdr3-alex [https://github.com/alexlee188/ghpsdr3-alex]

'''Project Goals'''

1. Open source (GPL) SDR software

2. Client-server network-enabled by design from the ground up

3. Customized server for each SDR hardware type. Currently supporting hpsdr, softrock, Perseus, and Ettus usrp.

4. Single dspserver that connects to single server. However, each server can have multiple Rx and Tx channels.

5. Multiple clients, such as QtRadio, that can concurrently connect to a single dspserver.

6. Full Rx and Tx capability for hardware capable of Tx

'''Note for HPSDR and ghpsdr3 (original) users:'''
In general, you cannot mix and match software from the two projects, ghpsdr3 and ghpsdr3-alex. However, the following MAY work:

1. Use the server (for hpsdr hardware) from the ghpsdr3 project to connect to your hpsdr hardware;

2. Use the QtRadio and dspserver from the ghpsdr3-alex project to connect to server;

3. It will work for Rx only, where the Rx IQ stream from the server will be sent to dspserver and then QtRadio, and the QtRadio client will be able to display the Rx spectrum and decoded audio;

4. dspserver from ghpsdr3-alex will NOT sent the decoded Rx audio back to the server and hpsdr hardware for playback;

5. You cannot use the Tx function yet;

6. You cannot use other clients, such as Java or Android from the ghpsdr3 project to connect to the dspserver from ghpsdr3-alex.
