Hi all,

Just managed to get a 30m kit built. Just testing into a dummy load right now.

When apply power the signal is spread over maybe 10Hz initially (wide band) after couple seconds it calms down and is a single signal.

Is this normal?

Run the output through a splitter/tap into a digital oscilloscope that also works as a spectrum analyser and I calculate 56mW out.

Argo displays nice clean signal abt 4Hz wide.

PSU BTW is an ATX PSU, added lots of chokes and RF clean now. 5.12V
I can see small variations in the signal though and if I monitor the output using ARGO.

Hi Dom

When apply power the signal is spread over maybe 10Hz initially (wide band) after couple seconds it calms down and is a single signal.

I wonder if that is AGC action? It'll be a massive signal into your receiver and probably the AGC either in the receiver, or in Argo, will take a little time to adjust to it.

That's my suggestion... other than that, not sure of any other possibilities!

Thanks Hans... probably explains it.
