I'm sure the 4meg was picked for the application it was to be used for... can probably be tweaked to a lesser spread.
No guess on the engine, but keep watching EBay.. surely one will turn up :-) ----- Original Message ----- From: neal Newman To: [email protected] Sent: Wednesday, February 04, 2009 6:38 AM Subject: Re: [Repeater-Builder] Need Info on - Sigma DX26FB Duplexer Interesting....... but its for 4 meg seperation...

But.. I do have a picture of the unit, with the factory specification tag and the testing report that goes with it. It is a brand new unit. If you Google 'Sigma duplexer', you will see what it (they) look like. Most of their units are similar in dimensions. Hi Freq: 234.5 Lo Freq: 230.2 Isolation: 89db Insertion Loss: 0.8db Just trying to figure out what it was used for, and if it might be applicable for use here. It was made in Ireland, but purchased from England. Researching what those frequencies might be used for in either country, but nothing definative.

But then again what do I know.....people are always trying to beat Physics and theory By making smaller packaging... .. Here is one. Buid a New Engine/motor that develops 1000 Hp. No Pistons. No Turbines/ its only 6 inches wide and weighs less than 400 lbs. Is it Possible.... ,and what is it?
