As I grow older my ability to differentiate signal from noise is changing in different frequency bands. Though it takes more concentration, I find now (I turned 50 last year) that I often listen belo
I think that it would not be hard to get the OMNI VI down to a lower CW note by use of the PBT and by getting the 9 MHz filter chain to the correct center frequency. Ten Tec built the model 221 to hi
The roofing filter mod does not give up any modes at all. It is a simple 4 pole filter switched in/out of the line according to the NAR filter switch positions. But the point is well taken, the origi
Rick, this isn't my first brush with binaural "magic". I got the latest and greatest DSP599ZX when it came out several years ago because of the binaural hype and it just didn't do much for me then or
Hi Rick, Yes I understand where that Inrad mod puts the new roofing filter. I guess what I did not understand is that with only one NAR button on the Omni VI (non version 3 or Plus) you sort of have
Would this kit work in the Corsair II or the Paragon II? The Corsair should have no need for such a thing. You don't have a wide roofing filter, you already have more roofing filter than the OMNI VI
Hey all - Anyone with an early OMNI VI do the Ten Tec modification to improve the in-passband performance of the product detector? I do not mean the 2nd order IMD mod that is done on the RF board (I
"There is no advantage over it vs. the master heater oven previously used..." so says Scott Robbins, and he should know what he is talking about. However, I own one of the first Omni VI's out the do
I may want to get just the crystal filter since I already have the board in my OMNI VI, but how big a deal is this? I use the model 221 filter (my favorite) and the 600 Hz roofing filter centered whe
Roger and Chuck - Thanks for the explanations, it is good to see the basics of the argument for a different center frequency. I believe I was the first guy to have the 221 (after bugging Ten Tec alon
No big deal at all, everything works as it should. Been there, done that! Clark WA3JPG On Dec 16, 2004, at 9:55 AM, john.brewer@us.schneider-electric.com wrote: I want to give this a try over Christm
I just bought an Omni 6 and was surprised that in an a-b comparison with my Icom 751A it seemed noisier and less sensitive. I expected just the opposite and was not prepared for these results. I chec
Hi Rich! Merry Christmas! I found the old 509 files! I have several articles with "lost info" regarding that rig, many really good mods and good insights into making that rig work very well. My advic
Here is a list of some articles I've seen regarding modifications for the 509: Turner, Page, "Improved CW Performance for Ten Tec Transceivers" The Short Wave Magazine, July 1986. (Turner no relation
Seems to be a lot of personal messages that somehow get sent to the list. I keep hitting the delete key as I have no business reading such things :-) . Meanwhile, I'm plotting to put the roofing filt
I'd be interested in corresponding with anyone who successfully installed the product detector mod in their OMNI VI (someone in EU?) I've got one here, I've got second hand information that it wasn't
Good idea regarding station visits! I am in Los Osos, CA., near San Luis Obispo (up the coast of CA. from Santa Barbara...) and would love to see an Orion. I am also happy to demo my tricked out OMNI
Hey Rich! I just procured a 509 that was adverstised as "mint". Well, guess what? It wasn't. Surprise, surprise! I hate when that happens. To start off, the receiver LO has been played with. The QRP
Well, you can't run out to Wal Mart to get this (well, I haven't checked) but at any bicycle shop you should be able to find "White Lightning" - it is a degreasing lubricant, specifically designed to
This is an important point, even for us non-cultists :-) There is at least one of the manual selling websites that offers to copy Ten Tec manuals for a price after being asked not to do so by Ten Tec
