Langstone Update 04/07/21
Posted: Sun Jul 04, 2021 5:02 pm
I have just released the latest update to the Langstone Microwave Transceiver.
The major update is that the spectrum and waterfall display are now active while transmitting, the S-Meter also now changes to show the Tx output level. The main use for this is as a confirmation that your microphone or key is working and adjusted correctly.
Note that both of these indications are derived from the digital signal being sent to the Pluto. They therefore represent what 'should' be being transmitted. They do not reflect the actual output level of the Pluto. They also do not reflect any TX attenuator setting because this is internally applied in the Pluto.
In order to get this working the method of passing the Spectrum display data between programs has been changed from using named Linux pipes to using UDP packets. This change should be transparent but there may of course be some hidden bugs that I haven't spotted.
