Horst,<br><br>Whilst you are correct that DD doesn't require a duplexer etc, if it is co located with a DV repeater, it most certainly does. Whilst there are a handful of manufacturers who make duplexers/Triplexers suitable, the prices start at about $2500, typically a lot more.<br>
<br>VK6 was the first to receive the special offer from WIA/Icom, however certainly wasn't first of the WIA repeaters to come online simply due to the key people running they show (Myself and Danny VK6ZUK) both worked some 60-80Hr weeks, often away for 2-3 weeks at a time. As such we took almost 12 months to get 2m/70cm/23cmDD up, and now almost another 12months later, still looking for a 23cm triplexer solution within budget.<br>
<br>We have had our fair share of critics, however fortunately most people who weren't involved knew the situation and were just happy that we were making it happen, albeit slow, and shut their traps.<br><br>Very little of this could could have been done without the many hours on the phone to Richard, and many hours of Richard remoted in to our gateway. Our hats to you Richard!<br>

Well, I have certainly ruffled a few feathers with my simple question.<br>
Incidentally, perhaps I missed it through all that QRM, but I didn't<br>
actually see an answer.<br>
The people involved seem to be more interested in telling about their<br>
herculean efforts to get/keep the system going than just answering a simple<br>
question.<br>
I know for a fact that the 23cm system which supposedly would be the<br>
mainstay for the Sydney area has never had an antenna plugged in after<br>
nearly a year. As for cavities which may be hard to obtain (I doubt that),<br>
the DD module does not actually need one.<br>
By the way, one thing I can not be accused of is never lifting a finger to<br>
make things happen.<br>
That's all I will say.<br>
<br>

Horst, VK2HL<br>
