ANAN100 PS Query

Postby W9KB » Thu May 28, 2020 6:10 pm

I took a few year hiatus from my radio, but I'm now back online with updated firmware (10.8) and Thetis (2.16.9) running very nicely.

A few years ago, I had Pure Signal working well with my amplifier and RF coupler (Coaxial Dynamics 7999-1)... but unsure which version my Hermes board is (SN1001012) and which input EXT1 or BYPASS to connect my feedback signal.

I'm been looking for a Thetis Pure Signal 101 explanation, but haven't found it yet... I assume it's similar to the old setup.

Any suggestions?

The algorithm has improved since the advent of "PureSignal 2.0".

Not sure if your prior involvement predates the incorporation of the automatic step attenuator functionality or not, but if it does you no longer have to manually set the step attenuator on TX, the algorithm does it for you.

The UI has also changed a little. See the "PureSignal 2.0 Release Notes" sticky topic in this sub-forum.

Other than that it is pretty much the same.

You almost certainly have the older RF board that uses EXT1. You will have to experiment to see which is correct. Don't forget to choose the correct "xxx on Transmit" option (Bypass or EXT1). The correct answer will be whichever choice results in a higher step attenuator value (more attenuation) when transmitting.

Do all Anan-100 models support Pure Signal II? My s/n is 1001012. Is this an early or later model. Asking for a prospective buyer.

They should all support it with an external coupler.
