Re: [Elecraft] Help on Configuration
Hi, If you have the FM filter you do not need the AM filter for listening to AM broadcasts with envelope detection. The FM filter is plenty good enough as the DSP allows you to set any bandwidth you please up to about 4.2kHz audio bandwidth (or thereabouts). This is wider than the 6kHz AM filter would allow and is really nice on strong, interference free signals. I am really looking forward to the arrival of the SAM detector though. I also use SSB mode when conditions are difficult as with strong selective fading. I do not have the AM filter as I have no desire to transmit AM.

Re: [Elecraft] Replacing the Lead acid shell inside K2 with Li-Po cells
I think that dangers of protected Li-Ion batteries are way overblown. After all, millions of laptops with those batteries fly every day with no problem. The charging problems are overblown as well. What happens if the battery life is 100 charges and not 500 when you need to charge every two weeks. By the time the battery is weak it is obsolete. I have 2 x 3 pack of computer Li-ion cells (with built-in protection) in my K2 for 5 years. Charged via a 12.6V 1A regulator with a laptop PS. Light and zero problems. It seems that charging each cell 4.2V (or 12.6V for 3 cells) with some current restriction is a good enough technique for longevity.

[Elecraft] K3 RF gain cal questions
I have performed the RF gain calibration (and also re-calibrated the s-meter) on my K3 using the Elecraft XG-2 generator hooked up to the receive antenna input of the KXV3 module. I used this input for two reasons: One reason is there is no chance of RF coming out of this input. Secondly, I have a KD9SV receive antenna switch box (Dxpedition model, with preamps for 80/160m) which allows me to have the XG-2 conveniently available at all times, simply by leaving it hooked up to one of the receive antenna jacks. Of course, I left the KD9SV preamps off for these procedures. First question: Is there any problem using the Rx input jack for the RF gain cal, instead of the ANT1 input as directed by the latest version of the K3 utility ? Second question: Suppose that I do an RF gain cal, then change the filter gain (in the Crystal filter configuration part of the K3 utility) of the roofing filter I used during the gain cal? Should I repeat the RF gain cal? Third question: What exactly is calibrated during an RF gain cal? I understand in a general sense that the overall RF/IF system gain is determined by many things, including scaling constants in the DSP.

Re: [Elecraft] K3 RF gain cal questions
Chuck Guenther wrote: Is there any problem using the Rx input jack for the RF gain cal No. Works equally well. Suppose that I do an RF gain cal, then change the filter gain (in the Crystal filter configuration part of the K3 utility) of the roofing filter I used during the gain cal?

But typical per- filter gain settings are in the low dB range (or should be), so a small change won't noticeably affect S-meter accuracy. What exactly is calibrated during an RF gain cal? The K3 uses a low-noise JFET IF amp. Gain control of this stage -- what we refer to as hardware AGC -- is achieved in two ways: by varying the current through the preceding PIN-diode attenuator, and by varying the JFET source voltage (its gate is at ground, so this varies the transconductance). A very wide range of IF gain control is achieved in this manner. But the gain curve varies a bit from one radio the next, because JFET pinch-off voltage varies (the voltage differential between gate and source at which drain-source current ceases to flow). The RF gain calibration procedure injects a DC voltage at the hardware AGC control node, sweeping it slowly over a 0 to 3 V range using a D- to-A converter. The DSP measures the resulting signal level (from your XG2), building a table of control voltages vs. 1 dB attenuation steps. This table can later be used by the DSP to determine the strength of incoming signals that activate hardware AGC; it simply monitors the AGC detector voltage at the control node. S-meter readings are a composite of the detector-voltage-to-dB table value and the DSP's internal representation of signals below the hardware AGC activation level (also in dB), so the S-meter is now calibrated. The RF GAIN pot, when rotated counterclockwise, simply adds a DC voltage at the control node (via the DAC mentioned above), so it is now calibrated as well, given that the DSP knows exactly what voltage to inject to achieve the desired attenuation.

Re: [Elecraft] K3: proposed SSB coarse tuning rate change
Hi Wayne, Wayne Burdick schrieb am 29 Sep 2009 um 10:29: We've had many requests to provide an 0.5-kHz VFO tuning step size in SSB modes. I'd like to substitute this for the current 2.5 kHz selection. The new set of steps sizes for SSB would then be: 0.1, 0.5, 1.0, 5.0 Most operators probably don't find 2.5 kHz steps to be particularly useful. 0.5 kHz, on the other hand, seems to be a useful lowest-common- denominator for tuning the SSB band segments. Each mode can have up to 4 step sizes with the K3's present per-mode data structure. I could add more step sizes, but that would require a much more extensive change. Please let me know if you have a compelling requirement for 2.5 kHz steps. I dont really care if the last step is 2.5 or 5 kHz. I think 5 is better for a fast move (QSY). My wish is that I can choose 0.5 kHz for the fast tuning rate with the clarifier knob. Most stations are sitting either at .0 or .5, and it is nice to check the band with the RIT knob and fine tune with the main VFO (which is rarely necessary in fact) This is what I use very often.

I have to agree with the need for the radio to be smarter about changing it's tuning rate automatically. This is a software change that would be helpful to most of us and is great on the Icoms.

These are unpowered bookcase speakers, but provide plenty of volume when used with the K3. They're very inexpensive and sound great. Size: about 4W x 8H x 4D. Having two speakers allows you to get L/R separation of the main and subreceivers, as well as take advantage of the K3's AFX simulated stereo mode. 73, Wayne N6KR On Sep 29, 2009, at 7:00 AM, Dan Copeland wrote: I am looking at speakers for my K3 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] speakers
These look really good and you can't beat the price. No we just need stereo amplifier so we can drive them from the line level output. 73, Doug -- K0DXV ac...@aol.com wrote: Here's the Best Buy webpage for these speakers: _http://www.bestbuy.com/site/olspage.jsp?skuId=7314523type=productid=11188 43685964_ (http://www.bestbuy.com/site/olspage.jsp?skuId=7314523type=productid=1118843685964) I bought these after Eric recommended them and have been very happy with them on my K3 on both CW and SSB in AFX mode.

Re: [Elecraft] Tuning Rate Change
I have to agree with the need for the radio to be smarter about changing it's tuning rate automatically. This is a software change that would be helpful to most of us and is great on the Icoms. I guess I'm the odd man out on this preference. I used an ICOM 735 for 20 years so I'm used to it, but I never really liked it ... never knew where I'd end up when I gave the knob a spin. Constant rate works great for me, especially with the coarse option and fast tuning with the RIT knob. 73 and thanks for listening, Carl WS7L K3 #486 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] speakers
I use a pair of these on my K3, but they're actually KLH Audio Systems Model 403A. The carton says they're weatherized and suitable for use in your boat, patio, workshop, etc The company's website rates them at 4 - 6 ohms, 40 watts. The company address is 11131 Dora Street, Sun Valley, CA 91352. 73!
