Hi Nick


I'm using EZmaster with two K3's without a problem.

> * Headphone cable from Ezmaster to FT2000 x 2

> * 24 relay outputs from Ezmaster used to switch aerials (6 Pak) and
> bandpass filters (Dunestar x 2) via a homebrew relay controller which allows

> 1. Wintest displays the correct band for operation but the Ezmaster relays

> 2. On Radio 1 if the VFOB tuning is moved, the Ezmaster relays will change

> 3. On Radio 2 if the VFOB tuning is moved, the Ezmaster relays will change

> So the question is how does the CAT interface work and how does Ezmaster
> know what band is in use? If it is Wintest that tells Ezmaster the band then
> there is a bug in Wintest. If Ezmaster works out the band by its own
> independent CAT comms then this is where the problems is and it is unlikely
> to be able to be fixed.

> Unfortunately, the alternative MicroHam equipment does not have the same
> configurable band relays as the Ezmaster and so a change to MicroHam will be
> a major redesign for a system that is frustratingly close to working.

> Incidentally, is anyone still using Ezmaster and if so, how have all the
> "firmware" problems been resolved? Is MicroHam now the only viable
> commercial option for an SO2R controller and will it provide the
> functionality that I am looking for – even if I have to find an external
> method for detecting the band and for switching aerials and bandpass
> filters?
