[Elecraft] RE: K2 RF Speech Processor?

I was surprised that RF clipping or compression for ssb was not mentioned as a "requirement" for the K3 (or K 0.5 or K4). The German unit looks great (tiny). Decades ago, before I forgot "the phone" I used a board produced by DATONG (UK). Back then (late 70's early 80's??) it was "small" but wo

Re: [Elecraft] K2 RF Speech Processor?

Hi Geoff, cut your weeds and we can both think hard on what "Speech Compression" really is. I got to thinking and about all it can be is clipping of the high voice peaks, and increasing audio drive. I will look at the ARRL Hand Book and see what they have. 73 Karl K5DI Geoffrey Mackenzi

Re: [Elecraft] K2 RF Speech Processor?

the K2 already has a "variale compression and noise gate " chip for the mic preamp... analog devices SSM2165-1 see: http://www.analog.com/UploadedFiles/Data_Sheets/2864404SSM2165_b.pdf#search=%22ssm2165-1%22 I too would be interested to see how much additional ""distortionless"" average ampl

Re: [Elecraft] K2 RF Speech Processor?

Hi, I have modified my K2 with the internal SSM2165. With the SSBC-Menu I can choose the compression 1:1 (1:1), 3:1 (2:1), 6:1 (3:1) and 9:1 (4:1) - the original in bracket -. The mod is very easy: You change RP5 to a 150k and connect Pin 2 and Pin 3 of RP5. Thats all! You find the mode in 'QRP

[Elecraft] Smooth Voice Controller? was K2 RF Speech Processor?

And along the same lines, what about a better VOX? The Smooth Voice Controller from April 1992 QST used a bucket brigade audio delay system to prevent any audio from being chopped off by the VOX. A QSK system for voice. Probably lots of better technology exists now than 14 years ago when that

Re: [Elecraft] K2 RF Speech Processor?

Thanks Bill for all the information and the fact that the K2 has a chip from Analog Devices that should do the desired job. I have the pdf thanks Bill and will study that with interest. A question. Does the K2 have a variable resistor at R! Compression ratio set? 73 Karl Bill NY9H

[Elecraft] Lightning damage result/repair

Hi Yesterday a thunderstorm ran through here, and while I didn't think it was anywhere too close, the SWR bridge diodes in the KPA100 thought otherwise. A few hours after the storm, I fired the K2/100 up and it was receiving fine, but my troubles started when I tried to tune up. I don't reca

Thank you Ray. I've included a note to move up or down for tomorrow's 20 meter net if anyone hears the music. Hopefully my 'hearing' will not be impaired too much by working from a city with a less than optimal antenna. If all goes well I'll pull your KX1 out from the noise floor. But,
