Don’t forget “contest” mode, where the meter reads S-9 for all signals :-) Grant NQ5T > On Apr 24, 2020, at 9:42 AM, Charlie T wrote: > > S-meters should be calibrated with 9 signal levels: > > *Faint - Signal barely perceptible > *Very weak signals > *Weak signals > *Fair signals >

Re: [Elecraft] K4 S-meter characteristics

It is very true that - in a contest situation - we aren’t often concerned with measuring signal levels. No argument. And, if contesting, DXing and rag chewing are all you use your K3 / K4 for, then I understand why you aren’t interested in the additional bells & whistles that are being

Re: [Elecraft] K4 S-meter characteristics

Agree completely. I find all S meters to be totally inaccurate and next to useless, including my K3S’. > On Apr 24, 2020, at 7:43 AM, Morgan Bailey wrote: > > Maybe it is just me but, Turn the radio on, adjust the audio/rf/agc > controls, hear the station, work him, move on. I dont need a

Re: [Elecraft] K4 S-meter characteristics

Maybe it is just me but, Turn the radio on, adjust the audio/rf/agc controls, hear the station, work him, move on. I dont need a fancy dbm or an iconic number of engineering controls, to say what the dbm was when I worked the guy. When you contest, who the hell cares, hear him, work him, move on.

Re: [Elecraft] K4 S-meter characteristics

Now that the K4 has exact knowledge of its gains and losses through the preamps, attenuators, splitters, bandpass filters and so forth, could this enable an alternate way of visualizing the receiver's range? This alternate measurement would be quite useful in setting the controls optimally for

Will the K4 have alternate S-meter scales since its direct sampling. Dbm, and Dbuv would be useful. Will the K4 have  better S-meter resolution or a menu option to set the dynamic range to give better indications of nulls or peaks? It would be nice to limit the range  in 2 scales S1 to S9 and

Re: [Elecraft] K4 S-meter characteristics

Simulation of traditional analog meters is possible, though not in the works at present. The advantage of the K4's present high-resolution bar graphs is especially apparent in transmit mode, where we simultaneously show forward power, SWR, ALC, and compression. We've found this to be extremely

Re: [Elecraft] K4 S-meter characteristics

I do not believe that I saw in any demonstrations but was any thought ever given to include traditional type meter faces rather than the horizontal meters used in the past elecraft products? Barney K3LA -- Sent from: http://elecraft.365791.n2.nabble.com/

[Elecraft] K4 S-meter characteristics

We've been making some final changes to firmware associated with the S-meters. Seemed like a good time to summarize how they work. The S-meters in the K4 have been upgraded from the K3/K3S: - separate, color-coded S-meters for VFO A and B - higher resolution (twice as many bars) - calibration
