It would actually make sense to use the filter with the least insertion loss - provided there is not enough IF gain to compensate for the higher loss of a narrower filter. That's something that was a
Generally speaking, the key clicks and the general hash most of us call phase noise (It's actually a mix of phase noise, partition noise, shot noise, Johnson noise, artifacts of multiple mixing, and
Yep, back in 1949 partition noise was defined as an instantanious shift in the relative currents in the elements of a vacuum tube. Circa 1963 anologous shifts in current flow occuring in solid state
Well, partition noise is not a major contributor to TX noise. But it's still there - along with all the other classic noise sources I learned about between WWII and the "Korean Police Action," as wel
It's awkward to measure my "almost built in" Orion but it looks like 12" center to center across the front and about 13" from the front of a rear leg to the front of the front leg. I would figure on
Well, I'll be doggone! If I turn the Orion's sidetone all the way off and the volume all the way down - sending CW into a dummy load - I can hear a clickity click coming from under the rig that's nea
Well, at least the new radio gives us something to talk about. But there are no perfect radios, and this one appears to be another radio that will need a PHD to operate. That is, a Post Hole Digger .
One should always remember the last laugh is the best laugh. An XLR jack in a mockup is no guarantee that there will be an XLR jack on the rigs that ship. Nor is an XLR plug on a mike a guarantee of
Interesting but from the way things usually work in this world, I rather suspect the new offerings by Icom and Vertex will be incrementally better than anything they have had in the past. Incremental
Barry, I tend to agree with you where it concerns "normal" folks who would destroy the machinery that threatens their livelihood, BUT - from observation, hobbyists are by no means "normal." And 15 gr
QSK gone away? Not on my Orion. I can hear another station between dits at what the MFJ 493 keyer says is 60 - and with what the internal keyer says is 60. So I certainly have QSK - at speeds higher
Hi Tommy: Well, K5TO is 66, I'm 69 myself, and way too much playing with high powered short barreled rifles has left me about like Red Skelton's Cauliflower McPug. So it's easier for me to run a litt
Personally, I "open" the file and let Windows put the opened version in the TTOrion directory. I have every update since day one in that directory, and if I ever do wind up with something I can't liv
Hi Lee; I suspect it will depends bit on just how fast you operate. If the 91's keying is as fast as the 87A you won't have much if any degredation in the QSK. Of course, I could tell the difference
HI Jerry: Well, my Orion and the amps are built in and it's a real pain to get them out single handed - but it is set up with two versions of Titan, so I can only speak about the keying loop - and no
Hi Bob, I guess I will have to re-read what I wrote. Sometimes with two grandkids, two dogs, and Kritter the hamshack cat buzzing around what I write does not come out all that clearly. Especially be
Well, I have my Orion EXT T/R delay set to 0. Nothing seems to want to hot switch so I will leave it there until there is some reason to change. 73 Pete Allen AC5E -- Never squat with your spurs on
Well, everyone has an opinion, subject to change, but so far my opinion of the IC7800 remains the same as it has been since day one. I have looked at what specs Icom has released on the IC-7800 and t
Well, I have only had three Omni VI's, the Plus and the two Option 3's. In each and every one of them I found the sound MUCH more agreeable with the PBT at 11 o'clock for LSB/CW and at 1 o'clock for
Well, everybody to their own taste as the good man said as kissed the pig, but 1.370 works FB for me. The NR is MUCH improved, the AN likewise, the sweep seems better for chasing the weak ones, and t
