Inasmuch as this probably does not need repeating, perhaps a re-calibration of the discussion is in order. I can't believe I'm the only one who sees this discussion going in circles without reaching
repeats, with Yuri: As Carl points out, the Orion (and like my Omni Six and Pegasus), the amp is keyed ahead of any actual RF output from the rig. Here's what I think you are suggesting: The CW cont
The difference is that semi would be fine but for the fact the CW speed may change (and does change through the contest), which would alter the hang time needed to key the amp "just" long enough to
"I don't think TT intentionally made CW PTT mistake. This happens in a big projects..." "Enable PTT functionality for CW, just like all the other manufacturers have been doing for decades." Fine. You
You are correct Bob. Their primary concern with the use of a dedicated PTT line is to avoid having their amplifier's T/R relay switch between keyed elements. And, semi-break-in is unacceptable to th
Hi Paul: Winamp opens and I add the URL: http://www.w8kc.com/stream.asx and press the "play" button but I don't hear or see the stream? Thoughts? -Paul, W9AC -- Original Message -- From: "Paul Valko"
W8KC's Internet stream is operating fine. Apparently the .ASX file extension requires a program like Windows Media Player, not an MP3 player. -Paul, W9AC of due

FWIW - I've had three separate Pegasus rigs in here during the past four years and have never had a single problem with any of them. -Paul, W9AC my one It
I ran a pair of ACOM amps with my Omni Six back in 1999 and the ACOM is more than fast enough to keep up with the Omni, even without using the bi-directional keying loop. -Paul, W9AC
2.8KHz Sort of... Originally, the INRAD 2.8 kHz filter for the 9 MHz I.F. slot was designed to widen the transmit passband to allow the CW carrier offset to rest sell within the filter passband and
I replaced the T/R relay in my Triton 540 with a high-voltage NPN transistor. I believe it is a 2N5551. The collector is open to the T/R line in the event I want to use an external amp. The transisto
But if a rig is made in JA and the parts come from Malaysia (as is certainly the case), does that make them 4th-world parts?...or 2nd-world parts? -Paul, W9AC
John...an excellent assessment of what is occurring in the Omni Six/Six Plus. Ss you point out, substitution with better 9 MHz BFO crystals goes a long way to 1) improve overall frequency stability,

This is a common anomaly with wide frequency splits. However, with narrow splits, you should not hear, nor see (on a monitor scope) the effect of wave-form truncation. It may be that there is a PLL a
That's right George. With the proliferation of transformerless audio designs during the late '60s and '70s, it no longer became necessary to "power match" the source with the load. For decades, dBm
