The difference between the two Millen GDO;s are numerous while the operation and external appearances are nearly identical. The 90651 runs off 120 VAC and uses a tube and associated power supply inte
It peaks here at K9RB in NE Florida, near Jacksonville, between 285 and 290 deg. That bearing runs right through Northern Texas, New Mexico, the Las Vegas area and Central to Northern California. Wit
I've found the "Sounds Sweet" to be a great asset to my TT 564 on SSB, but still prefer my old and trusty Hallicrafters R46B with original speaker circa the early 50's for CW. If you are fortunate en
Lou, The first thing to try in the situation you describe is to loosen and then retighten all the screws that hold the boards to the chassis. Many boards get their ground through these connection poi

GM Paul, LP makes a world of difference with my model 564 Omni 6 Plus. It seems to be more effective at ambient noise reduction than the NR does! I believe the NR was also quite effective prior to my
Charley, It sounds to me likely to be a plate to grid short in one of the 3-500Z tubes rears it ugliness only intermittently, sitting idle. This is a common mode of failure with old 3-500Z tubes. It
The 3-500Z type tubes were designed with tungsten-thoriated filament material. This is a material much different than standard tungsten, although, grant it, any material heated and cooled will exhibi
The roofing filter mod/addition from INRAD does not require any soldering except for power. The rest of the connections are all provided for with mini coax and plugs on the filter accessory board. A
Bob, The FT-1000D puts out ~200 watts PEP while the Orion is only half that. I find that most grounded grid 3-500Z pair amps require about 135-140 watts of drive power before flat-topping to generate
Bob, In your original post, you did not indicate that you were backing off the drive power of the Ft1KD. Measuring the RF output level you have it set on SSB can produce varying results. All being eq
Mike, it depends much on which filter you have installed for CW in the N1 or N2 position. If you've got a TenTec #221, that provides the best match with the INRAD #765 as they both have center freque
After more than 45 years of continual hamming on all bands and modes, I can honestly say that I never have used an antenna tuner and never found any system that will outperform a resonant antenna fed
I certainly won't disagree with you and I am also fortunate enough to not require an antenna tuner on any band but 160 (didn't get the built in antenna tuner in the Orion as I don't need it). Not all
That would be a good name for them, Rob. In essence, the place to use a matching network to avoid feedline losses is at the antenna feedpoint. Although using an antenna tuner at the transmitter end o

Hi Ken, I think everyone may have different preferences. These preferences may actually change with age and changes with our hearing. I have found, for me, 40 some years ago I used to prefer CW tones
