Re: LF: ROS 503.600kHz beacon

[Gary - G4WGT <g4wgt@tiscali.co.uk>]

Hello Jim,

OK, the thing is that when ROS is set to PTT loop mode, when a call is detected (may be a valid frame received or possibly operators call sign) it stops the loop & sends an alarm sound to the PC motherboard sounder. Problem is that the sounder is not very loud & usually not heard.

The idea then is that the operator goes into QSO mode to reply to the caller. It's a great idea & would work better if the alarm audio was sent to the default sound card & would be heard thro' the amplified speakers.

This is an extract from the user guide :-

It warns us through the PC's speaker when a message is received. This option is well suited to keep on listening while carrying out other activities in the computer with the programme minimized.

I will make a suggestion to Jose about directing the alarm signal to the default sound card.

Dear Gary, LF Group,

OK Gary - was getting 100% copy of your beacon signal until I called you... from the way your signal disappeared after I transmitted, I had a sudden feeling my call had initiated some kind of self-destruct sequence in your shack ;-)

Will hopefully be around this evening at some stage to try again.

Cheers, Jim Moritz
