241. [TenTec] Low Pass Filter Switch Points For Pegasus (score: 1)
Author: Duane Grotophorst <n9dg@yahoo.com>

I was thinking about the new 60M band and was wondering which LP filter is used for the 5MHz segment. After some investigation I found that 60M uses its own LP filter. Here are the frequency switch p

That is exactly what the RX-320D is. http://www.tentec.com/TT320.htm It outputs the 12KHz IF signal on a newly provided jack on the back panel. Its main limitation is that it will only provide for 2.

Yes it does still have all the DSP stuff of its own, but the 12KHZ signal that is provided on the back panel is before any of the A to D and DSP of the RX-320 itself. However the DSP in the RX 320 wi

Are you sure you're using the new 32 bit update.exe? It works much better than the old 16 bit one on NT kernel based OS's like Win2K and XP. Just updated all of my Pegs running on com ports 3-6. No p

Yupp, it really just boils down to whether the energy is being transferred into an electromagnetic load vs. a mechanical one (sound waves). I view it as simply being which it is most commonly associa

Interesting results. I wonder how different the results would be though if you were to use a sound card program like Spectran fed from the line level out of the Orion (and RX-340) to find the -6 and

On the other hand if you were going to buy both new it would make more $ sense to buy two Orion?s. Then you would have both a spare TX and two really decent general coverage RX's to boot. 565/340 = 1

Perhaps a better way to express this is to say that the Orion does not ADD as much noise as other receivers do. It is a common misnomer when folks say that a receiver "pulls" a signal in, or out of t
