It wasn't my term. But I think "full-bodied" cw means a slightly wider I-F to establish background noise that some ops want to hear, particularly if the receiver has exceptional gain distribution and in-band IMD, which the latest Icoms do have. This gives articulation to cw signal outs of a quiet back ground of noise, and so long as you are not dealing with an exceptionally strong signal nearby, hard-wired fast agc can give relative strength to the competing signals. Then, a good cw op can pick out stations actually easier than with a 400hz filter where RIT becomes more necessary. Of course on the Icom radio there is no choice but to do this because 3khz is the narrowest setting, though you could ask for more DSP filtering.
So, here again, is what I mean: set you K3 for 2.7khz and I-F DSP at 500hz and tune in a s-9 signal. Now engage your narrow cw filter (I can do 400hz, 250hz, and 200hz). Listen to the I-F back ground noise decrease relative to the signal. Notice too that 2.7 hz with 500hz of DSP sounds more "full-bodied" than 400hz, 250hz, 200hz. Of course, this is all good when you are trying to hear a weak signal anyway as opposed to running a pileup of stations. My point is (or was in the discussion about this) if you like running stations with an Icom you can enjoy running them in the same way with K3. But what has to happen to the Icom radio when a signal like the one Guy describes gets within the 3 khz roofing filter? On the k3 you can engage a 200 hz filter and carry on the east coast -EU battle If there is an advantage to contesting in Idaho it is that EU stations from over the pole are seldom over s-9 and don't blink, you will miss the EU opening, hi. However, I have seen east coast signals nearly peg the meter of k3 a few times in 300z cwt. 73, Will, wj9b KX1, k2, so2r K3/P3 CWops #1085 CWA Advisor levels II and III http://cwops.org/ -------------------------------------------- On Tue, 9/20/16, Ron D'Eau Claire <r...@cobi.biz> wrote: Subject: Re: [Elecraft] Running stations with k3 To: "'F5vjc'" <foxfive....@gmail.com>, "'Guy Olinger K2AV'" <k2av....@gmail.com> Cc: "'Elecraft Reflector Reflector'" <elecraft@mailman.qth.net> Date: Tuesday, September 20, 2016, 6:03 PM A very long time ago (1950's) we called 'em "California Kilowatts" knowing that their driver stages were running a kilowatt at least and then the big amp following... On A.M. (not so much SSB then) 100% modulation was a starter. 150% produced a nice splatter that told everyone across the band that you were "on the air". The same with CW using very square wave keying that announced your presence over many kc/s with clicks that allowed everyone to read your call and know that "Big Al" (or whomever) was on his key. They seemed rampant on 75 and 20 meters. So the geography has shifted, but not the crazy interests of some operators. BTW, if you are interested in a 15 kW H.F. amp check out the "Tsunami": http://ta5fa.blogspot.com/2013/03/15kw-hf-rf-amplifier-tube.html I'm sure that some operators would use it to drive a "big" final amp, Hi! We can hope they don't find a way. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of F5vjc Sent: Tuesday, September 20, 2016 3:01 PM To: Guy Olinger K2AV Cc: Elecraft Reflector Reflector Subject: Re: [Elecraft] Running stations with k3 This is the degeneration of Amateur radio, yes really, it's true.
