Adding your WebSDR server to Pocket RxTx

[yo3ggx]

Hi,

NOTE: This procedure require Pocket RxTx v3.0 and up. Please ask your user to update Pocket RxTx (if still at v2.x or below), in order to be able to connect to your server.
This is the procedure to add a new WebSDR server in Pocket RxTx:
- prepare an sdr.xml file using the one below as a template (this is the one used on my WebSDR server in KN34bk).
- put the file in the root of the websdr server (pub2 directory).
- prepare 2 jpg images: one of 480x320 to represent your station and a logo in 128x128 pixels format.
- in the xml file you will enter the url for the two images and for a web page to describe your setup.

<centerfreq> (in KHz) and <samplerate> (in Hz) tags are the same as in websdr.cfg file

When everything is ready, send me a mail and I will add your server in the master xml file.

Please take care to validate the xml file to be sure that is free of errors.
You can use an online tool for that, for example:
http://www.xmlvalidation.com/

For any question, please post a message in this thread.

Hello,

how to add QO-100?
It seems, that 999 MHz in the app is the upper limit.

Hello,

There is no limit in the app. Frequency is represented as a long value, so plenty of room for maximum frequency.
Can you detail a little bit your issue?

Hi,

maybe I am making some mistake.
I've defined QO-100 band as follows:

Code: Select all

	<band>
		<nr>7</nr>
		<name>QO-100</name>
		<centerfreq>10489750</centerfreq>
		<samplerate>1024000</samplerate>
	</band>

So it is around 10,49 GHz. When I click band and choose QO-100 from available bands, frequency is switched to 2147,48365. When I click on frequency "counter" green keypad opens. There I can type max 3 digits, which must be followed by dot (999.99999 is max what I can enter). Waterfall for QO-100 looks OK i think, but there is no usable audio, because changing frequency with wheel - changes it at around 2147 MHz.
I've enabled for testing purposes this band - please check if you can reproduce this issue.

Thanks!

Hello,

I can confirm it is an issue in Pocket RxTx v3.3.3. Will be fixed in v3.4 I'm working on.
Thank you for your report.
