Re: [Elecraft] K3: listening to both rcvrs - Reduced receiver noise floor
Tayloe Dan-P26412 wrote: single composite receiver with a lower noise floor. If you added just enough RF pre-amplification to overcome the signal splitting loss to N receivers, adding more and more receivers Only if the pre-amplifiers are noiseless, or at least contribute equivalent input noise power that is much less than the equivalent power generated by the receiver times their gain. In that case, you could do better by using the pre-amp on one receiver and dumping the excess gain later in the system. That's better in noise, but you may compromise dynamic range more. in parallel will produce a composite receiver that has a better and better noise floor. This is in essence what the space telescope folks do. They gang many dishes and many receivers together across a very large area to get an enhancement on the signal and space noise and a suppression of the effective receiver noise contribution. In this case, there is no splitting loss, and the noise is uncorrelated because it is being received at different locations. -- David Woolley The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio List Guidelines http://www.elecraft.com/elecraft_list_guidelines.htm ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] RE: K3 Filter Questions
Dave, It is unlikely, but possible that your 250 Hz filter is defective. My original 400 Hz filter had a center frequency offset beyond the 250 Hz correction limit (as an 8-pole, supposed to be 0 Hz offset). If you can center the signal in another filter's bandbass (use CWT to be sure) and then switch to the narrow filter and it is no longer there, but noise is, tune the receiver (first try shifting the DSP) and see if you find it nearby. If it's way off you may need to configure it as if it were a wider filter (say 1 kHz) and have the DSP set to 1 kHz, so it will get through. I have had an opportunity to evaluate quite a few K3 filters lately, and this is the only one I've seen that was obviously off frequency -- in my personal K3 -- naturally g! Needless to say, Elecraft replaced the filter immediately and that fixed the problem. snip 1. When I turn my 250 Hz filter on in config, and then select that filter (which is FL5 here)I can hear noise coming through but no cw signals come through. I can see the signals on my PowerSDR/LP-PAN setup and CW Skimmer. Signal comes through all the rest of the filters O.K. Yes, I opened the radio, and all the filters are installed. snip Regards, Joel Joel R.

re: [Elecraft] K3 - How to get more headphone output
In the recent discussions of this subject, I don't recall any mention of Rx EQ settings, or FLx gain settings as ways of obtaining more output.

I don't recommend that you do this, although of course yo can. When you go to 100 Hz or 50 Hz width, the RxEQ is no longer in effect so you'll lose this boost. I'd suggest more sensitive headphones if setting AF Gain to HI doesn't give yu the boost you need. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

It's a risky to assume that ALL RX noise is uncorrelated after being detected. While there may be differences in RF level due to antenna displacement and transmission line length, the detected audio may be correlated if some specific noise source is heard by both receivers. In other words, noise can be random or correlated. Examples: an impulse noise generated from a power line or hash generated by a swithing power supply. While both are broadband sources, they are NOT random. If both antennas hear a source like them, the detected audio will be correlated between the two receivers! So in that case, there's no advantage from combining the two RX outputs. The 3 dB advantage arises when the noise is truly random, like the noise preamps that are not common to the two receivers. 73, Jim Brown K9YC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 Transmit Alignment
Ron, Do you have power output on any band? Try them and see. The display of 0.1 watts is as low as it will indicate. An indicated 'output' of 0.1 or 0.2 usually means no power output at all. Check the other bands and get back with us for further troubleshooting, your answer will indicate where to look next. If you do not have power output on any band, you will likely need to build the RF Probe from the parts provided with your kit (unless you have an oscilloscope with a 10x probe). 73, Don W3FPR Ron McCurdy wrote: I had trouble aligning on all bands with the KPA.

Thus, when operating CW on split, the screen would be flickering all the time between the two frequencies.

Re: [Elecraft] K3: Item for 'Wish list ' maybe
Hi, Before I bought the K3, I too, was concerned about the fact that the main (A) VFO display would not change when transmitting with split enabled, but I am no more. There are a number of indications in the display that I am in split mode, the delta-F LED is lit, the TX arrow points down to the B VFO and unless you have an alternate display in the B VFO it will display the transmit frequency. To have the main (A) display change when transmitting really only makes sense when there is just one frequency display (which is what I was used to, too). And I agree with Greg that having it swapping with each dit on CW would drive me crazy. I also agree that when operating split it is prudent to have the B display set for the B VFO frequency.

I like to operate QSK and to me having the VFOA frequency change rapidly while sending CW would just drive me bonkersmore so than I already amjust ask my dog! :) snip - AB2TC - Knut -- View this message in context: http://n2.nabble.com/Item-for-%27Wish-list-%27-maybe-tp1516191p1517001.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 Beta firmware rev. 2.67: Main/Sub AF balance control; AGC-off AF limiter
K3 beta-test firmware revision 2.67 (with DSP rev 1.96) is now available. Please send any problem reports to [EMAIL PROTECTED] For instructions on how to load beta firmware, please see: http://www.elecraft.com/K3/k3_software.htm Full details appear below. 73, Wayne N6KR * * * MCU 2.67 / DSP 1.96, 11-18-2008 * MAIN/SUB BALANCE CONTROL: If CONFIG:SUB AF is set to BALANCE, then the SUB AF GAIN control becomes a main/sub AF balance control when the sub receiver is turned on (including diversity mode). In this case the MAIN AF GAIN controls the AF gain level for both receivers. When SUB AF is at 12 o’ clock, both receivers will be at full volume (main left, sub right). If SUB AF is rotated fully counter-clockwise, you’ll hear only the main receiver. If it’s rotated fully clockwise, you’ll hear only the sub receiver. At intermediate settings you’ll hear both. A BALANCE control is very useful for contesting and split operation. But it can also save a lot of AF gain control tweaking (i.e., matching main and sub), since MAIN AF controls both main and sub receiver audio. * AGC-OFF AF LIMITER: An adjustable AF output limiter has been added for operators who turn AGC off. This can protect your ears if a large signal appears. Signals or noise above the threshold will sound highly distorted due to the limiting action, reminding you to back down the AF or RF gain. The associated menu entry, CONFIG:AF LIM, defaults to NOR. Typical settings for those who often turn AGC off are 17 to 23, but some experimentation will be required. * EASY SUB RX ANTENNA SWITCHING: A hold of RX ANT will alternate between MAIN and AUX for the sub receiver’s antenna, if the sub is installed. This is faster than going into BSET to switch the sub antenna. * SUB ANT SAVED SEPARATELY FOR DIVERSITY/NON-DIVERSITY: At many stations, the sub receiver’s AUX antenna is only used in diversity mode. The K3 now remembers which sub RX antenna setting you use in diversity and non-diversity cases, so you won’t have to use BSET as often. * DIGOUT0 SIGNAL (ACC connector): This now behaves as described in the owner's manual. When a transverter band is selected that is configured for low-power operation (i.e., .01-1.50 mW, and using the KXV3’s XVTR IN/OUT jacks), DIGOUT0 provides a low-resistance path to ground that could be used to activate a small relay or other circuitry. At all other times the DIGOUT0 line will float (high-Z). If all transverter bands are configured for low power, then DIGOUT0 can be used as a “transverter band selected” signal. * POWER LEVEL ON XVTR AND HF BANDS: Switching between HF and transverter bands no longer modifies the present HF band power setting. --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
