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

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

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
Hi Jeff - Heck, I bought one of these way back when, took it "backpack mobile" up into the Delaware Water Gap, too. Those were the days (not necessarily better, but I sure was younger!) The 505 has a
I've seen a lot of hams unaware of the problem Mike points out. Tune a receiver around your transmitted signal, you'll see that you've got a serious spur out of band, but close enough that your anten
Thanks for the info regarding the NB, Dave. I think you pioneered (I recall some early correspondence with you on this!) the roofing filter ideas for the OMNI VI. I appreciate it. One note to this (e
Hi Jim - Which one do you need? There is one for the 9 MHz IF (model 220) and one for the 6.3 MHz IF (I don't think there is a model number). Clark WA3JPG ____________________________________________
Heck, it works. It just doesn't work on a very wide variety of noise pulses. I've taken advantage of mine on occasion, it certainly took out automobile ignition noise pretty well, but many other nois
The best thing I did with the Corsair was to get an ANC-4 noise canceller. That little unit took a little fiddling, but it took out much noise, power lines, ignition and even some of the atmospherics
No, that is a problem. Check on the MFJ 1026, I think it had provisions for QSK (I have one but it is in the garage, I could tell you tomorrow). Clark WA3JPG _________________________________________
You know, the NYE tuner is truly "built like a tank" but I had one and gave it up pretty quickly because the tuning range was more limited on my particular antennas than for my Johnson matchbox and m
Hi Allan! Do you have the oven or the TCXO? If TCXO, I don't know how to help, but if the oven, I bought a new one :-) It was the (well known) "hunting" behavior of some of the earlier ovens, they we
Hi Pete - This can be as simple as static cling :-) . Try wiping the plastic face with a moist cloth and see if it stops. If so, clean the thing (inside and out) of dust. I "fixed" a few this way. Cl
