Hi - Is the Omni VII built-in speech processor function RF-based or AF-based? The manual says it is an RF-based function, but I thought I was told differently when they sold me a Model 715 RF-based p
Neither, it is DSP based. Now is that RF or AF? 73 Bob, K4TAX _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/te
Bob, to answer your question, one would have to know the frequency it is working on. However I seem to recall it's something like 48 kHz. In that case then it would be more like RF than AF. Reason: W
Interesting - Stan at TenTec HQ says the Omni VII built-in speech compressor uses "AF Based" compression. And... yet... Page 31 of my owner's manual states: "The speech processor used in the Omni VII
I had the 715 with my Omni VI+'s and loved it. When I got the Omni VII, I used the internal processor (only 10%) and I get so many unsolicited comments on the audio during contests and while working
My take, the 715 is best suited for radios that do not have speech processing or those that do not have good speech processing. The 715 does add certain benefits not found in some analog processing s
I've kept the 715 to use with my OMNI-VII. I also have a FLEX-1500 as sub-receiver of the OMNI-VII using the N4PY modification and DXLab Commander to slave it. The FLEX-1500 has a panadapter mode wit
Gary, I disagree, it is not an AF clipper. It may not do as good of a job of amplifying and clipping as the 715 does, but then that's a question of design. If it is operating in the DSP, it is RF, no
A DSP speech processor is not an RF clipper. In DSP you are working with signals that are all numbers. You can modify the numbers according to some clever algorithm and increase the average talk powe
OK Carl, that makes sense. But the DSP operates quite like an RF clipper, in that the "harmonic" distortion that AF clippers typically have is not present in it. In that respect, both DSP compression
Check the various forum archives on this topic please as I believe Carl, Bob, myself, and others had a rather spirited debate on this very topic only a few years ago when the 715 product was first re
My measurements indicate the internal processor can increase average output as much as 12 dB. Typical at 45% is 6 dB to 8 dB average increase. 73 Bob, K4TAX __________________________________________
HOLD THE PHONE, GUYS.... IT IS AN RF-BASED COMPRESSOR AFTER ALL! HERE IS WHAT STAN BROCK SENT TODAY, which appears to have some input form the infamous John Henry... I love to see tag-team problem- s
In my evaluation of the Omni VII Speech processing system I concluded that there are some 9 definable steps found over the displayed range of 0% to 100%. These are not exactly linear in their appeara
For clarity on this point, James is referring to an email I sent him off-line comparing AF and RF compression, NOT my post earlier to the group, which Carl corrected. Cheers Rick, DJ0IP HOLD THE PHON
