No, Bob, I hooked the Key Pulser to the "KEY" input of the Omni 6+ not the keyer paddle input. Otherwise I would still be getting a string of CW characters when I set the pulser to 100% instead of a
Interestingly enough, Ken, I just tried using the Omni 6+ with its internal key. With the keyer adjusted for about 30 WPM, a string of dits gives what appears to be an ~33% duty cycle, but I would ha
If found some derivations on the internet that suggest that WPM = 2.4 X the dit frequency. The specs on INRAD website say 50ms pulse rep rate = 48 WPM, which would be consistent with that number (1/5
The FT-1000MP MK5 with the key click mod is a good example of this. Unless you pre-bias the ALC circuit, it still clicks on leading characters and inter-word leading characters. Looks (and sounds) re
Hi All, I just ordered an INRAD roofing filter kit for my Omni 6+. Initially I specified the INRAD 765 (centered on 500 Hz offset), but now I am wondering if I wouldn't be better off with the 763 (75
Thanks for the detailed reply, Roger. I have Ten-Tec's #219 and #282 in my N2 positions, so I should probably change my order with George from the #765 to the #763 since the center frequency of the #
Yes and no, Gary. Using good coax certainly helps, but as the feedpoint impedance gets very high (like what you get when operating a 1/2 wave dipole on an even harmonic) then losses skyrocket even wi
I am curious, what are you basing that on, Bob? My computer modeling suggests otherwise, but I am using the NEC-2 engine, so I don't know how valid my data is. The ARRL antenna book mentions that inp
Actually if you have a very-low impedance load, a low impedance line is better. Open wire line made from say #14 copper has more loop conductor resistance per unit length than a piece of Andrew LDF4-
Jerry, I'd be careful about how I was doing the testing. I've noticed that when testing rigs right next to each other with a common physical connection that there are all sorts of common-mode sneak p
Neil, My L-7 relay input jack shows an open circuit voltage of 27.7 VDC and a short circuit current of 3.2 milliamps. I've had no problems keying it directly with my Omni 6+. Dunno about the specs on
Joel, What was the input voltage to the Paragon? I think it maybe sensitive to input voltage. Before I retired it, I ran mine off of a 13.8V supply and never had any complaints about my TX purity, no
Hi Joel, You'll notice from the pictures on the link I posted that the spur content was a function of frequency as you might expect from a multi-loop synthesizer. You might want to check several diff
Hi Jerome, I run my Omni 6+ and Drake L-7 amplifier with a pair a EU-2000i's (using the parallel kit) when operating 160 meters from the desert. Line regulation from these generators is excellent. Th
LOL. I guess the impedance matching is only a side-effect of the "ass kicking" :-) :-) Mike, W4EF........................ _______________________________________________ TenTec mailing list TenTec@co
Steve, This table just shows the percentage of incident power reflected and transmitted at a mis-matched RF transmission interface. You'll notice that the "% of Loss" versus transmitted power (what t
Hey Jerry, VSWR = (1 + |RHOv|)/(1-|RHOv|) For VSWR = 6:1, |RHOv| = 0.71 (i.e. 1.71:/0.29) Return Loss = 20*log(|RHOv|) = 20*log(0.71) = -3dB I think you forgot to square the voltage reflection coeffi
Hi Jim, The Centurion is a pair of 3-500Z running in zero-bias mode (something like 2500Vdc on the plates), so the power gain is much lower than the Titan amps with the 3CX800s. Driving the Centurion
When I operate SSB with my OMNI 6+ I get random beeping in audio output during my voice transmissions which comes and goes. I find it very distracting and would like to get rid of it. Has anyone else
I nominate my 12 gauge pump that I am going to use to shoot my POS Omni 6+ next time it starts randomly beeping on SSB :-) 73, Mike W4EF _______________________________________________ TenTec mailing
