Re: [Elecraft] P3 Waterfall
You can increase the waterfall sensitivity by adjusting the REF LVL to place the noise right at the bottom of the spectrum display and then increasing the SCALE setting. The same REF LVL and SCALE settings are applied to both the spectrum and the waterfall displays. For further details, see the PX3 User's Manual section called How to Set Up and Interpret the OX3 Display. To erase a FN key setting, use the FN Erase menu function. You can also over-write it by assigning a different function.

First, when I engage the Marker function and use it in the waterfall window, it comes up on the P3 screen, but not on the external monitor (although it does work on the upper panadapter portion of the monitor screen). How do I get it to work on both waterfall screens? Second, I run the K3 in conjunction with my Flex5000A. I notice that the Flex waterfall appears to have considerably more detail and a more robust color scheme than the P3. The Flex also has more detail (I see signals on the Flex that barely come up on the P3). I switch between the same antenna, so that should not be a factor. Is there a sensitivity adjustment on the P3 that I need to play with? If not, I must admit that the P3 waterfall does not appear to perform nearly as well as the Flex. Finally, once you assign a function to an FN series button, is there a way to delete the assignment, short of assigning another function over it? Thanks for your input. K0GFY R.

Re: [Elecraft] Don't have a 50W dummy load
I can add, for those who want a good 130+ watt dummy load and are willing to build one (a quart size Heath 'Cantenna'), take a look at http://k4eaa.com/dummy.html. I built 2, one for myself and another for my grandson (we did it as a project together). It is not difficult at all. You may want to check for mineral oil at a lower price than the drug store.

Re: [Elecraft] Don't have a 50W dummy load
It's a good idea to check the resistance of any used dummy load, especially one that has some age on it. The resistance of my 30+ year old Heath Cantenna gradually reduced to 42 ohms. This was enough error for the power meter to indicate a potential transmitter problem. W1GA is selling non-inductive replacement resistors on eBay for use in the Cantenna. I purchased one and it brought the resistance back to 50 ohms. - Dave My Web Site -- View this message in context: http://elecraft.365791.n2.nabble.com/Don-t-have-a-50W-dummy-load-tp7600633p7600647.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] Don't have a 50W dummy load
I have heard the same thing about the original Heath Cantenna. I have a homebrew gallon size Cantenna that I built many years ago. I happened along some large wattage carbon resistors (about 1/2 inch in diameter and 2.5 inches long - maybe 25 watts each) and used several of them in parallel to create a 50 ohm load ( I recall it was 11 560 ohm resistors). This was when I was a cash-flow restricted ham. I measured mine recently with my antenna analyzer and was surprised to find it was still less than 1.15 SWR up through 30 MHz. This is despite reports that the old 'trusted' carbon carbon resistor changed value with age. In any case, I am happy with the results of that old homebrew dummy load. In the same batch of resistors, I also had many 1500 ohm units. I was going to put 30 of them in parallel for a dry dummy load, but the lead length was excessive and the leads gave it an inductive characteristic above 14 MHz. The original Cantenna used a single resistor which apparently did change in value with aging. 73, Don W3FPR On 3/24/2015 6:44 PM, Dave KW4M wrote: It's a good idea to check the resistance of any used dummy load, especially one that has some age on it.

Re: [Elecraft] K3 Diversity VFO Linking
Hi James, Here is how you can use split in diversity mode: Operating Split in Diversity Mode You can operate split when in diversity reception. Because both receivers are tuned by VFO A when in diversity mode, you must revert to the operating techniques needed for a single receiver radio. You will be listening to the DX station on VFO A and searching for the station that has successfully broken through the pile-up with VFO B, which can be tuned independently of VFO A. VFO B controls the transmit frequency in split operation. 1. Tune into the DX station with VFO A. 2. Tap AB to transfer VFO A to VFO B. 3. Start up diversity reception by holding SUB for more than two seconds. 4. Hold SPLIT to enter split mode. Now you will be transmitting on VFO B. 5. When you hear the DX station go back to a station in the pile-up, hold the REV switch to reverse VFO A and VFO B temporarily. Quickly search through the pile-up using VFO A to find the station going back to the DX. When you find it, release REV and get ready to call the DX on the next over. 6. You may also hold B SET to enter b SEt mode. You will hear the Main receiver in the left ear and the Sub in the right ear. This temporarily overrides diversity mode allowing you to hear the DX station on VFO A and the pileup frequencies on VFO B.

Re: [Elecraft] KX3 Roofing filter question
Joshua, Probably not. The ultimate BW of your receiver is set by the DSP and noise power is sort of proportional to BW. The purpose of the roofing filters is to protect the ADC sampler at the head end of the DSP from very strong signals that could drive it to saturation. Noise, other than atmospheric and galactic, needs to be attacked at the source. Like getting rid of your switching wall warts and power supplies. So long as the atmospheric noise is not saturating the ADC, reducing the DSP BW is the only really effective way to reduce it's impact, and that's a lot easier on CW than on SSB. Different roofing filters are not likely to make much difference at all unless they're more narrow than your DSP setting.

[Elecraft] P3 Waterfall
I recently purchased a new P3/SVGA unit, and am using it with my K3 (serial # 6999). I have a few questions. First, when I engage the Marker function and use it in the waterfall window, it comes up on the P3 screen, but not on the external monitor (although it does work on the upper panadapter portion of the monitor screen). How do I get it to work on both waterfall screens? Second, I run the K3 in conjunction with my Flex5000A. I notice that the Flex waterfall appears to have considerably more detail and a more robust color scheme than the P3. The Flex also has more detail (I see signals on the Flex that barely come up on the P3). I switch between the same antenna, so that should not be a factor. Is there a sensitivity adjustment on the P3 that I need to play with? If not, I must admit that the P3 waterfall does not appear to perform nearly as well as the Flex. Finally, once you assign a function to an FN series button, is there a way to delete the assignment, short of assigning another function over it? Thanks for your input. K0GFY R.

The P3 is a very powerful and versatile product, and the SVGA board increases its capabilities. It's scan width can set to any value between 2 kHz and 200 kHz. Amplitude range can be set between about 10 dB and 80 dB. The unit can be calibrated to the voltage at the K3's input terminals (a signal generator is required). Both amplitude and waterfall can be averaged or not, and average settings are adjustable. There are separate settings for the P3 display and the external display. The frequency resolution is quite good, and is improved by a factor of 10 or more by the separate FFT used to drive the SVGA output.

Re: [Elecraft] Don't have a 50W dummy load
Tony, Scolding time :-) One thing that I believe should be in every ham's shack is a dummy load capable of handling the maximum power that your station can develop. Ridge Equipment has a 50 ohm 75 watt dummy load good up to 1.5GHz for $11.95, but you will need an adapter for UHF connectors so that is an additional $5. See https://www.ridgeequipment.com/store/dummyloads.html. If ever you run into a problem, the first check is to see what happens when you transmit into a dummy load. That removes many variables - like RFI problems and antenna problems. It is the first check I recommend. If the rig works into the dummy load, you need to look for the problem somewhere other than the rig. I have had rigs sent to me for repair only to find that there is nothing wrong. The resulting repair charge is greater than the cost of a good dummy load. If you look for one at a hamfest, take your ohmmeter along to check if it is still a 50 ohm load - some are burned out from excessive power. 73, Don W3FPR On 3/24/2015 3:25 PM, Tony Estep wrote: Well, now I downloaded the new firmware, only to discover that I have to do the 50W calibration. I have a 5W dummy load, but no 50W. The 5W calibration went okay. So do I have to get a 50W dummy load before I can use the K3 again? Or should I back down to the previous firmware? Or what? __ 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 Message delivered to arch...@mail-archive.com
