181. [TenTec] Removing Computer noise from your receiver (N4PY) (score: 1)
Author: n9dg@yahoo.com (Duane Grotophorst)
Date: Sat, 6 Oct 2001 07:21:41 -0700 (PDT)
My experience has been that with each new computer and/or monitor I buy the amount of computer noise is less than the one before. I've been even more pleasantly surprised that as CPU clock speeds hav

Vin, Perhaps I can give you some additional thoughts on the RX320 and the Pegasus because I do have both. Even though the RX320 and Pegasus do share a lot in common, the Pegasus is a significantly be

I have noticed that field day ops are some of the worst for crowding the calling frequencies on VHF and UHF. I can only attribute that behavior to many of the operators being primarily HF operators w

I would like to see the ARRL add a product review test where they show the audio output spectrum of the RX audio passband with a 50-ohm load on the RX input. With today's digitally based radios (DSP

This being catch 22 is true to a limited point, but it has more to do with the evolution of technology. These issues of DSP and other digital artifacts are akin to the transition from tube receivers

There are number of tricks that can be done to watch a segment of a band, everything from straight forward scanning to real expensive spectrum analyzers. What is so appealing about the dual Pegasus (

No the Ten Tec radios prior to the Omni V and Paragons all use a permeability tuned VFO. Mechanically it is just a "slug" of ferrite material with a thread in the inside of it, the VFO knob then simp

Yep, and while a color display is nice, and can also be extremely useful, - it just doesn't belong on the radio itself. And also adding an Ethernet adapter wouldn't even cost as much as a video adapt

Obviously I'm talking about a whole new radio architecture (user interface/control side) that is beyond what the Pegasus/Jupiter/Orion now are. A radio with its "computer" intelligence built around t

Yes it is, - but it can be managed. From the reviews I've read the folks at Winradio have done a good job of keeping all that nasty noise out of the G303i PCI RX card they've recently introduced. Agr

Of the 6 Pegs here none have had any relay problems at all. In fact only one of them has had any problems of any kind, and that is the most recent one that I've picked up off of the used market. It c

Actually that makes perfect sense, the 40M position is a low pass filter so the the 75M signal will pass through it quite happily. The only harm done would be that the level of attenuation of the 75M

Yes the 580 Delta does use a 6.3Mhz IF, in fact there is NO 9MHz IF in the 580 at all. It directly mixes the incoming signal with the "band" crystal, that mixer's output then falls in the range of 11
